Earthquakes are some of the most devastating natural disasters. Millions of dollars worth of property are damaged and a hundred die every time a big magnitude of eater quake strikes. It is in this regard that everyone must read and know about earthquakes and be prepared to mitigate the damage. Furthermore, the topic of earthquakes is quite often asked in exams. Preparing for this topic will enable them to have an edge and score more marks in the English paper.

To serve the above-mentioned purpose, Vedantu has come up with the Earthquake essay. This essay is prepared by the experts who know what exactly is required to know and weeding out points that are not important. The essay is very precise and would surely allow students to successfully claim marks in the essay question and even stay prepared when an earthquake actually strikes.

What is an Earthquake?

When the earth’s surface shakes, the phenomenon is referred to as an earthquake. Precisely, the sudden trembling of the earth’s surface is the cause of an earthquake. Earthquakes are regarded as one of the deadliest natural disasters. Huge damage and loss of property are caused by earthquakes. There are various types of earthquakes. Some of them are severe in nature. The most dangerous thing about an earthquake is that it is quite unpredictable. It can cause several damages without any previous indication. The intensity of an earthquake is measured by the Richter’s scale. Generally, earthquakes occur due to the movement of tectonic plates under the earth’s surface.

Types of Earthquake

There are four kinds of earthquakes namely

Tectonic Earthquake,

Volcanic Earthquake,

Collapse Earthquake and

Explosive Earthquake.

Tectonic Earthquake

It is caused due to the movement of the slab of rocks of uneven shapes that lie underneath the earth’s crust. Apart from that, energy is stored in the earth’s crust. Tectonic plates are pushed away from each other or towards each other due to the energy. A pressure is formed because of the energy and movement as time passes. A fault line is formed due to severe pressure. The center point of this dispersion is the epicenter of the earthquake. Subsequently, traveling of the waves of energy from focus to the surface causes the tremor.

Volcanic Earthquake

The earthquake caused by volcanic activity is called a volcanic earthquake. These kinds of earthquakes are of weaker magnitudes. Volcanic earthquakes are categorized into two types. In the first type, which is called volcano-tectonic, shaking happens due to input or withdrawal of Magma. In the second type, which is termed as Long-period earthquake, tremors occur due to changing of pressure among the earth’s layers.

Collapse Earthquake

Collapse Earthquake is the third type of earthquake that occurs in the caverns and mines. This is another example of a weak magnitude earthquake. Mines collapsed due to underground blasts. Consequently, seismic waves are formed due to this collapsing. Earthquakes occur because of these seismic waves.

Explosive Earthquake

The fourth type of earthquake is called an explosive earthquake. This is caused due to the testing of nuclear weapons.

Effects of Earthquake

The effects of earthquakes are very severe and deadly.

It can cause irreparable damage to property and loss of human lives. The lethality of an earthquake depends on its distance from the epicentre.

Damage to establishments is the direct impact of an earthquake. In the hilly areas, several landslides are caused due to earthquakes.

Another major impact of an earthquake is soil liquefaction. Losing the strength of water-saturated granular material is the cause behind this. The rigidity of soil is totally lost due to this.

Since the earthquake affects the electric power and gas lines, it can cause a fire to break out.

Deadly Tsunamis are caused due to earthquakes. Gigantic sea waves are caused by the sudden or abnormal movement of huge volumes of water. This is called an earthquake in the ocean. When tsunamis hit the sea coasts, they cause a massive loss of lives and properties.

Earthquake is termed as one of the most huge and lethal natural disasters in the world. It proves the fact that human beings are just nothing in front of nature. The sudden occurrence of earthquakes shocks everyone. Scientists are working rigorously to prevent the damage of earthquakes, but nothing fruitful has been achieved yet.

Examples of Devastating Earthquake

The city of Kobe in Japan witnessed a devastating earthquake on January 17, 1995, killing more than 6,000 and making more than 45,000 people homeless. The magnitude of the quake was 6.9 at the moment which caused damage of around 100 million dollars. The governor of Kobe spent years on reconstruction and made efforts to bring back fifty thousand people who had left home. Japan geologically is a highly active country. It lies upon four major tectonic plates namely, Eurasian, Philippine, Pacific, and North American which frequently meet and interact.

The second incident is in Nepal where an earthquake struck on April 25, 2015. About 9000 people were killed and almost 600,000 structures were destroyed. The magnitude of the quake was 7.9 and the repels were felt by neighbouring countries like Bangladesh, China and India. The disaster caused severe damage of millions of dollars. All the countries across the world including India garnered to help Nepal by sending monetary aid, medical supplies, transport helicopters and others.

Another safe place to hide is under the table or under the bed. If one is sitting in a multistory building, avoid taking a lift and only use the stairs. In this kind of situation, one should never panic and stay calm. Let the earthquake pass until then keep hiding in the safe spot. Once over, come out to evaluate the situation and take appropriate actions.

3. How to mitigate the effects of an earthquake?

Prevention is better than cure. It is always a better idea to take necessary actions before an earthquake has struck. In the first place, send a copy of all your documents to someone reliable. In case of an earthquake that destroys your important documents, there would always remain a facility to retrieve them. Research and know if your city is in a seismic zone. One should also take note of earthquakes during the construction of a house and lay emphasis on a seismic-proof house.

4. How can one teach people about the effects of an earthquake?

There are many ways one can raise awareness about the effects of earthquakes. There is Youtube and Instagram which could be used to disseminate all the knowledge about the earthquake and its impact on humans. You can also go to schools and colleges to conduct a seminar whereby the students could be told about the mitigation and steps to take when an earthquake strikes.

Earthquake Essay

Essay on Earthquake - An earthquake is a natural disaster that occurs when two tectonic plates collide. The force of the collision creates seismic waves that travel through the earth's crust, causing the ground to shake and buildings to collapse. Here are some sample essays on earthquakes.

100 Words Essay on Earthquake

Earthquakes can happen anywhere in the world, and although their occurrence is not predictable, there are some things you can do to make yourself more prepared in case one does strike. This includes having an earthquake kit ready to go, knowing how to drop, cover and hold on, and staying informed about any potential risks in your area. Make sure you have an emergency kit stocked with food, water, and other supplies, and know what to do when an earthquake hits. If you're not sure what to do, it's best to stay away from windows and other objects that could fall on you, and head to a safe place.

200 Words Essay on Earthquake

500 words essay on earthquake.

Earthquakes are a natural disaster that come with a lot of dangers. The shaking and movement of the earth can cause buildings to fall down, trapping people inside. The shaking caused by such a sudden change is usually very minor, but large earthquakes sometimes cause very large shaking of the land. The shaking waves spread from the spot at which rock begins breaking for the first time; this spot is called the center, or hypocenter, of an earthquake.

If you're inside when an earthquake starts, drop to the ground and cover your head. The earthquake's magnitude is related to the amount of earthquake energy released in a seismic event.

Different Types of Earthquakes

There are three types of earthquakes:

Shallow | A shallow earthquake is when the earthquake's focus is close to the surface of the Earth. These earthquakes are usually less powerful than the other two types, but can still cause a lot of damage.

Intermediate | Intermediate earthquakes have a focus that's located between the surface and the Earth's mantle, and are usually more powerful than shallow earthquakes.

Deep | Deep earthquakes have a focus that's located in the mantle, which is the layer of the Earth below the crust. They're the most powerful type of earthquake, and can even cause damage on the surface.

An earthquake can cause damage to buildings and bridges; interrupt gas, electrical, and telephone services; and occasionally trigger landslides, avalanches, flash flooding, wildfires, and massive, destructive waves of water over oceans (tsunamis).

The Dangers Associated With Earthquakes

The shaking of the ground can cause objects to fall off shelves and injure people. If you're outside when an earthquake starts, move away from tall buildings, streetlights and power lines.

An earthquake can also cause a tsunami, or a large wave, to form and crash onto the shore. Tsunamis can be very dangerous and can reach heights of over 100 feet.

How to Prepare for an Earthquake

When an earthquake is imminent, your first step should be to find a safe spot. The most ideal spots are under sturdy furniture or inside door frames. It is best to stay away from windows and anything that can fall over.

Once you've found the safest place, it's time to prepare for the shaking. Grab some blankets, pillows and helmets if possible – all of which can provide extra cushioning against falling objects.

Additionally, you should always keep an eye out for debris that could cause injuries, such as broken glass and sharp objects.

Finally, stay calm until the shaking stops, and monitor local news reports for additional information on how best to handle the situation.

What to do During an Earthquake

The moment an earthquake hits, it is important to stay as calm and collected as possible. Safety is the first priority so you must stay away from windows and furniture that can fall on you, and protect your head with your arms if needed.

If an earthquake occurs while you are indoors, stay away from anything that could fall or break such as windows, mirrors, or furniture. Do not run outdoors as shaking can cause glass and other materials to fall from the building structure. Instead, seek shelter under sturdy tables or desks. If there is no furniture available, move to a corner of the room and crouch down protectively with your arms over your head and neck.

It's also important to take note of any gas lines that could be affected during an earthquake and shut them off if necessary in order to prevent fires from breaking out due to exposed pipes.

After the Earthquake: Recovery and Assistance

When the shaking stops, there will be a period of recovery.

Don't enter any building if it has visible damage due to the earthquake - it's better to be safe than sorry.

You should contact local aid organisations like the Red Cross for additional help with sheltering, water, food and other essentials.

Stay in touch with local officials about any services provided for those affected by the earthquake.

Make sure you also have a plan for what to do if you're stuck in an earthquake, and know how to get in touch with loved ones in case of an emergency.

By being prepared and knowing what to do, you can help ensure that you and your loved ones are safe in the event of an earthquake.

An earthquake is a sudden shaking (or trembling) of the earth which lasts for a very short time.

An earthquake is caused by the violent movements of rocks deep inside the earth’s crust.

Earthquakes can cause immense damage to houses, other buildings, bridges, dams and people, etc. A lot of people get killed when they get buried under the debris of collapsed houses and other buildings during an earthquake. Earthquakes can also cause floods, landslides, and tsunamis

A major earthquake occurred in India on 26th January 2001 in Bhuj district of Gujarat.

Another major earthquake occurred on 8th October 2005 in Uri and Tangdhar towns of North Kashmir.

A great loss of human life and property occurred in both these earthquakes.

A major tsunami (caused by an earthquake) occurred in the Indian Ocean on 26th December 2004. All the coastal areas around the Indian Ocean suffered huge loss of life and property during this tsunami.

The other destructive natural phenomena such as cyclones and lightning can be predicted in advance to some extent so that we get some time to take measures to protect ourselves and minimise the damage to life and property. This is not so in the case of earthquakes.

Earthquake is a destructive natural phenomenon which cannot be predicted in advance. Nobody can tell when and where an earthquake will occur. This unpredictable nature of

earthquakes makes them even more dangerous. In order to understand why earthquakes occur, we should first understand the inner structure of the earth.

Inside Earth

The inside of earth is made up of three main layers : Core, Mantle and Crust.

The innermost part of the earth is called its core. The core of earth is made up mostly of iron. The core of earth is extremely hot. Most of the earth’s core (called outer core) is liquid (molten iron) whereas the inner part of core (called inner core) is under such high pressure that it is solid.

The central region of earth (between the core and crust) is called mantle. Mantle is the middle layer of the earth. Mantle is mostly made of dense, solid rocks. Some of the mantle is a mixture of solid rocks and hot molten rocks (liquid rocks) like the lava from a volcano. Heat coming from the core of earth warms the mantle. This heating sets up huge convection currents in the mantle. The giant convection currents occurring in the mantle can make the mantle move very, very slowly.

The outermost layer of earth is called crust . The crust of earth is made of comparatively lighter rocks than that of mantle. The crust of earth is thicker where there is land (or continents). The crust of earth under the oceans is thinner. The crust of earth is made of many huge pieces of flat rocks. Each piece of the earth’s crust is called a plate. The plates of earth on which continents exist are called continental plates whereas those plates of earth on which oceans exist are called oceanic plates. The solid plates which make up the earth’s crust are floating on the partially molten rocks of mantle beneath. Due to convection currents taking place in the mantle, the plates of earth’s crust are moving around very, very slowly. The reason the earthquakes occur is that the earth’s crust is made of a number of plates which are able to move. Earthquakes occur mostly at the edges of moving plates of the crust (or boundaries of the moving plates of the earth).

Occurrence of Earthquake

The earthquakes occur when the moving plates of the earth’s crust :

(1) slide past one another, and (2) collide with one another.

(1) The plates of earth’s crust are made up of huge rocks having rough edges. Due to their highly rough edges, the movement of two crust plates relative to one another is not smooth. When the two huge plates of earth’s crust slide past one another, they rub against one another ferociously and the rocks on their edges get entangled. Due to entanglement of the rocks at their edges, the two crust plates stop moving for some time. During this time, the plates are still pushing against one another and trying to move but they are not moving.

This builds up pressure between the two plates of crust. When sufficient pressure has been built up between the two crust plates, the entangled rocks of the two crust plates break open suddenly with a big jolt.

When the entangles rocks of the two crust plates break open suddenly with a big jolt, the earthquake occurs releasing a tremendous amount of energy.

This sudden release of tremendous amount of energy produces shock waves (or seismic waves) which make the earth shake. After the earthquake, the plates of earth’s crust start moving again and continue to move until they get entangled again.

(2) When the two plates of the earth’s crust moving in opposite directions collide with each other head on, then the ends of these crust plates buckle and fold forming new mountains and causing earthquakes. A tremendous amount of energy is released when the two huge plates of the earth’s crust collide with each other. This tremendous amount of energy sends shock waves (called seismic waves) throughout the earth. When these shock waves reach the surface of earth, the ground starts shaking violently. This shaking of the ground is felt as an earthquake.

Seismic zones or Fault zone

The weak zones of earth’s crust (which are more prone to earthquakes) are called seismic zones’ or fault zones.

Major earthquakes occur in the well defined ‘seismic zones’ called earthquake belts. The seismic zones mark the edges of the huge mobile pieces of the earth’s crust called plates. . In India, the areas most threatened by earthquakes are Kashmir, Western and Central Himalayas, the whole of North-East, Rann of Kutch, Rajasthan and Indo-Gangetic Plane. Some areas of South India also fall in earthquake danger zone.

Seismograph

Earthquake tremors produce shock waves (called seismic waves). The shock waves travel in all directions through the Earth and also reach the surface of the earth.

Seismograph is an instrument which measures and records the magnitude of an earthquake in terms of the shock waves it produces.

Seismograph detects the shock waves produced by an earthquake and also records the shock waves on the paper in the form of a graph. Seismograph is also known as seismometer .

A seismograph consists of a heavy weight suspended from a support with the help of a strong wire. The support is attached to the base of seismograph. And the base of seismograph is fixed rigidly to a solid rock on the surface of earth. A pen is attached to the lower end of the hanging heavy weight. This pen can trace lines on a graph paper wound around a rotating drum which lies beneath it.

The purpose of using a freely suspended heavy weight is that, being heavy, it has a lot of inertia and hence it remains stationary during an earthquake when the rest of seismograph (including its support) fixed to the earth shakes (or vibrates) during an earthquake.

Working of Seismograph

When an earthquake occurs, the earth starts shaking due to which the base of seismograph fixed to the earth also starts shaking. But the freely suspended heavy weight (and the pen attached to it) do not shake during the earthquake, they remain stationary. Since the graph paper on the rotating drum shakes with the shaking earth, the pen attached to suspended weight records the vibrations produced by earthquake on the graph paper which moves under it. The pen traces the relative movement between the shaking earth and the stationary, suspended heavy weight. This trace on the graph paper records the earthquake. The seismograph record is also known as seismogram .

A seismograph record (or seismogram) shows seismic waves or earthquake waves recorded on a graph paper by a seismograph. It also shows the duration (or time) for which the earthquake lasts, in seconds.

By studying the seismograph records of an earthquake produced at various seismic stations, scientists can construct a complete map of an earthquake giving its focus, epicentre, magnitude and duration.

The place inside the earth’s crust where the earthquake is generated, is called focus of the earthquake. The focus of an earthquake is deep underground.

The seismic waves spread from the focus and travel through the earth in all directions.

Focus is actually source of an earthquake. The point on earth’s surface directly above the focus is called epicentre.

Richter Scale

The magnitude (or intensity) of an earthquake is expressed on the Richter Scale . The Richter Scale is a series of numbers from 1 to 12 used to express the magnitude (or size) of an earthquake.

An earthquake of magnitude 2 is ten times as strong as an earthquake of magnitude 1.

An earthquake of magnitude 3 on Richter Scale is 100 times as strong as an earthquake of magnitude 1 on the same scale. And an earthquake of magnitude 6 on the Richter Scale is 1000 times stronger than an earthquake of magnitude 4. An earthquake of magnitude 6 on Richter Scale has 1000 times more destructive energy than an earthquake of magnitude 4.

An earthquake of magnitude 1.5 on the Richter Scale is the smallest earthquake that can be felt by us. An earthquake of magnitude 4.5 on the Richter Scale causes some damage but not much damage. The earthquakes having magnitudes higher than 7 on the Richter Scale are really destructive earthquakes.

Both, Bhuj and Kashmir earthquakes had magnitudes greater than 7.5 on the Richter Scale. The earthquakes which measure 8.5 or more on Richter Scale are devastating. During these earthquakes, the affected part of earth’s surface shakes violently. Such earthquakes can destroy entire cities and villages causing a great loss of life and property.

Protection Against Earthquakes

Earthquakes are highly destructive and they cannot be predicted. So, it is necessary that we take precautions to protect ourselves all the time.

Some of the important precautions which can be taken by the people living in seismic zones for protection against earthquakes are as follows:

(i) All the houses and other buildings in seismic zones should be designed and constructed in such a way that they can withstand major earthquake tremors.

(ii) In highly seismic areas, the use of mud and timber (wood) for building houses is better than using heavy construction materials. The roofs of houses in such areas should be kept as light as possible so that a roof falls during an earthquake, the damage will not be too much.

(iii) The cupboards and shelves should be fixed to the walls so that they do not fall easily when shaking occurs during an earthquake. Glass bottles should not be placed on high shelves and heavy objects should be placed low to the ground.

(iv) The objects such as heavy mirrors, photo frames, wall clocks and water-heaters, etc, should be mounted securely on the walls at such places in the house that they do not fall on the people in the house in the event of an earthquake.

(v) All buildings (especially tall buildings) should have fire-fighting equipment in working order.

In case an earthquake occurs, we should take the following precautions to protect ourselves depending on whether we are at home or outdoors at that moment.

If we are at home when an earthquake occurs, then:

(1) We should take shelter under a sturdy table or a kitchen counter and stay there till the shaking due to earthquake stops. We should cover our head with hands.

(2) We should stay away from tall and heavy objects (like steel almirahs, cabinets, book racks and refrigerators), so that if they topple , they may not fall on us.

(3) We should also stay away from glass windows that may shelter due to vibrations.

(4) If we are in bed, we should just move on the bed to be close to a wall but not get up from the bed. We should protect our head with a pillow.

If we are outdoors when an earthquake occurs, then:

(1) We should stay at a clear spot away from buildings, trees and over-head power lines. We should also sit on the ground.

(2) If we are in a car (or bus), we should not come out of it. The car (or bus) should be driven slowly to a clear spot away from buildings, trees and over-head electric wires.

Essay on Earthquake for Students in English | 500+ Words Essay

January 2, 2021 by Sandeep

Essay on Earthquake: It is a major natural disorder that causes trembling of the Earth’s surface. Heavy loss to both lives and property are usually recorded when an earthquake occurs. When the Earth’s tectonic plates glide over one another, it creates seismic waves. If these waves are of a higher magnitude, then destructive earthquakes occur. Earthquakes have different names depending on their location like tsunamis, landslides, avalanches and large displacement. Seismographs measure the magnitude of earthquakes.

Essay on Earthquake 500 Words in English

Below we have provided Earthquake Essay in English, suitable for class 5, 6, 7, 8, 9 and 10.

Earthquake is the shaking of the earth, which releases an immense amount of energy that creates seismic waves. These waves can be ranged from weak to strong. Some seismic waves are too weak to sense and too strong to destroy cities and create violence. The seismic activity refers to the rate and frequency of earthquakes experienced over the years.

Manifestations of the earthquakes are the shaking and the displacement of the ground. A tsunami is caused when the epicenter of a massive earthquake is displaced by strong waves. Because of the earthquake, the phenomenon of landslides and volcanic activity takes place. This can also be defined as the seismic wave that is caused by naturally or by humans. The occurrence is mostly due to the cause of geographical faults. The other reasons include landslides, volcanic activities, nuclear tests, etc.

Types of Earthquake

Tectonic Earthquakes – Tectonic plates are the loose, cracked fragments present in the crust of the earth. These plates move slowly and gradually under the surface. The movement of the plates is in different forms. They can move towards each other, away from each other, in the sliding directions, or in a colliding way. A huge tremor occurs when these plates slide over one another. They are the reason for massive mass destruction.
Volcanic Earthquakes – Volcanic Earthquakes mostly occur after or before the phenomenon of the eruption. The magma eruption from the earth leaves a space behind. To fill the space, the rocks displaces towards the space that results in the severe earthquakes. The cases of massive explosions occur when magma blocks the vent during the volcanic activity.
Explosion Earthquakes – The main reason for these kinds of explosions is nuclear testing. Men mostly trigger these earthquakes. In the year 1930, numerous small towns and villages were devasted because of the testing of nuclear weapons by the United States.
Collapse Earthquakes – They occur near underground mines and are generally smaller. In addition, these are called as mines burst. Pressures that are generated within the rocks instigate these earthquakes. These earthquakes mostly prevailed in the small towns where the underground mines are located.

Effects of Earthquake

Ground Shaking is considered the most familiar experience one finds during the earthquakes. It is the series of seismic waves that hit the ground from a small to large scales. The consequences noted are the damages to the buildings, troubles in standing stable, and destruction of natural habitats in the cases of vigorous shaking.
When the wave’s movement is actually along with the fault, this leads to the total distortion of the ground. The cases for actively ground ruptures are quite rare. The surface of the earth is left with deep cracks.
When there occurs a sustainable shaking and direct rupturing of less stable slopes, it gives rise to the phenomenon of landslides.
Tsunamis, popularly and often called tidal waves, are termed as the most hazardous event. The main cause of this is the movement of the seafloor vertically, causing a series of water waves. The speed of the Tsunami has been measured for more than 700 km/hr. This speed resembles the speed of the jet planes, and it can reach up to 27 meters.

Steps to Control Earthquake

Personal Measures

When an earthquake occurs under table and door-frames are quite the right place to seek shelter.
Try not to be in some confined areas. Run in the open area, if possible
Take preventive measures to avoid risks from liquefaction, landslides, etc.
Keep a check on the gas lines and pipes, after earthquakes.
Keep a close connection with the authorities, and try to follow the instructions.

Technical/Biological Measures

Limited measures to be taken to prevent the damage from secondary effects. As no measures can be taken to prevent earthquakes.
The design of the buildings should be earthquake resistant.

Information about Earthquake and Causes

Earthquakes can take place at depth of up to 720 km below the earth's surface.
However, the ones, that produce significant effects at the surface of earth, usually occur no deeper than 70 km.
Every year, there are about 1,000 earthquakes around the world that are strong enough to cause damage to life and property.
Major earthquakes are much less frequent but are more destructive.
Major earthquakes usually do not occur alone; when one such earthquake happens, there is usually another one at a nearby location.
Sometimes, an earthquake also has foreshocks. Foreshocks are smaller earthquakes that happen in the same place before the larger (main) earthquake occurs.
As at present, scientists (geologists) cannot predict (very) accurately whether a given earthquake is a foreshock that is likely to be followed by a larger (main) earthquake.

Effects of an Earthquake

Earthquakes can cause damage to the buildings, bridges, dams.
Earthquakes, in many cases, may cause great loss of life.
Earthquakes can also cause floods and landslides. Landslides, triggered by earthquakes, often cause more destruction than the earthquakes themselves.
Sometimes the earthquake occurs beneath the ocean floor. Such earthquakes can lead to a tsunami.

Cause of an Earthquake

It is now known that these plates are moving around very slowly — just a few millimetres every year.
This (small) movement is due to the movement of the molten magma inside the earth.
The movements of these plates cause changes on the surface of the earth which may cause an earthquake.
Tremors , on the earth, can also occur when a volcano erupts, or a meteor hits the earth, or an underground nuclear explosion is carried out.
However, most of the earthquakes are caused by the (natural) movement of earth's plates.

The boundaries (rough edges), of the plates, may get interlocked due to friction.
The rest of the plates, however, keep on moving. This causes a tension to build up in the plates.
When the force of moving plates overcomes the friction at the edges, all of their stored energy gets released. The earth shakes/vibrates around this point.
The vibrations, at the point of the release of energy, give rise to shock or seismic waves ; these are very much like the ripples in a pond that arise when a stone is thrown into it.
These seismic/shock waves shake the earth as they move outward through it.
When the waves reach the surface of the earth, they shake the ground as well as all the things on it, i.e. buildings, bridges, dams, etc.

Protection Against Earthquake

Earthquakes are highly destructive natural disasters, leading to significant loss of life and extensive damage to property on a global scale each year. In response, the disaster management committee has implemented various safety measures to minimize the devastating effects of these catastrophic events. Developing effective strategies and promoting disaster management awareness is paramount in mitigating the impact of earthquakes and ensuring our safety. This article aims to provide a comprehensive understanding of earthquakes, including their causes and effects, along with detailed instructions on how to respond during and after an earthquake.

What is an Earthquake?

An earthquake refers to the shaking of the earth’s surface caused by a sudden release of energy within the earth’s crust. This release of energy generates seismic waves, commonly known as S waves. The intensity and characteristics of an earthquake are determined by the seismic activities occurring in a specific region.

During an earthquake, the stored energy accumulated within the earth’s crust is suddenly released, leading to the rapid movement and displacement of rock masses along fault lines. This movement produces vibrations that propagate through the earth in the form of seismic waves. The two primary types of seismic waves are S (secondary) and P (primary) waves .

S waves, also called shear waves, travel through the earth by causing particles to move perpendicular to the direction of wave propagation. These waves are responsible for the side-to-side shaking motion experienced during an earthquake. On the other hand, P waves, or compression waves, cause particles to move in the same direction as the wave propagation. P waves are the first detected during an earthquake and are responsible for the initial abrupt jolts.

Understanding the nature of earthquakes and the behaviour of seismic waves is crucial for assessing the potential risks associated with these natural disasters. It enables scientists and experts to study seismic patterns, develop early warning systems, establish building codes for earthquake-resistant structures and educate communities on preparedness and response measures.

What Causes an Earthquake?

Earthquakes occur due to sudden tectonic movements within the Earth’s crust. The Earth’s crust is divided into large sections called tectonic plates , which float on the semi-fluid layer known as the asthenosphere. These plates are constantly in motion, albeit very slowly.

When two tectonic plates interact, various types of boundaries can form, such as convergent and divergent and transform boundaries. The most powerful and destructive earthquakes typically occur at convergent boundaries, where two plates collide or slide past each other.

At a convergent boundary, one tectonic plate may be forced beneath another in a process called subduction. As the plates collide or slide past each other, immense pressure and friction build-up. Eventually, the stress becomes too great, causing the rocks along the plate boundaries to break and slip. This sudden release of stored energy generates seismic waves, resulting in an earthquake.

In addition to tectonic movements, other geological activities can also trigger earthquakes. Volcanic activity, for instance, can cause earthquakes when magma rises through the Earth’s crust, creating pressure and fracturing the rocks around the volcano. The disturbances caused by these movements and ruptures within the Earth’s crust generate vibrations that propagate in all directions, shaking the ground. These vibrations are the seismic waves that travel through the Earth and are detected by seismographs.

It’s important to note that the build-up of stress and the subsequent release of energy in the form of shock waves are the fundamental mechanisms behind earthquakes. The magnitude or strength of an earthquake is determined by the amount of energy released during this process.

Delve Deeper into the Causes of Earthquakes

We present to you an insightful video that explores the fascinating mechanisms behind seismic activity. By watching this video, you’ll gain a deeper understanding of how earthquakes are caused and the factors that contribute to their occurrence.

What to do During an Earthquake?

When it comes to earthquakes, being prepared can make all the difference. Here are some essential steps to take before the disaster strikes:

Before the Earthquake

Make Connections Flexible

Ensure that gas lines and appliances are properly installed with flexible connections. This helps prevent gas leaks and reduces the risk of fire hazards during an earthquake.

Create an Earthquake Readiness Plan

Develop a well-thought-out plan that includes identifying a shelter area in your home. Stock up on essential supplies such as canned food, a well-stocked first aid kit, ample water, dust masks, goggles, firefighting equipment, a flashlight and a working battery-operated radio. These provisions will prove invaluable in the event of an earthquake.

Consult Architects and Structural Engineers

Building sturdy structures is vital for minimizing earthquake damage and ensuring the safety of occupants. If you reside in an earthquake-prone area, it’s crucial to consult with architects and structural engineers before constructing buildings. They can guide you in implementing the necessary measures and adhering to regulations set by the disaster management committee.

Spread Awareness

Share the knowledge and importance of earthquake preparedness with your friends and family. By educating those around you, you contribute to creating a safer community.

During the Earthquake

When an earthquake strikes, quick thinking and appropriate actions can save lives. Here are some important guidelines to follow:

Stay Indoors

Remain indoors until the shaking stops and it is officially announced that it is safe to exit. Taking cover beneath a sturdy table or bed can provide vital protection against falling objects.

Avoid Hazardous Areas

Steer clear of bookcases, heavy furniture and appliances that may topple over during the earthquake. Your safety should always be the top priority.

Find a Safe Spot

Seek shelter under a sturdy piece of furniture, such as a table or bed. Hold on to a post or any other fixture to maintain stability and minimize the risk of injury.

If Outdoors, Move to an Open Area

If you are outside when the earthquake occurs, find a clear spot away from buildings, trees and power lines. These objects pose a significant danger during seismic activity.

After the Earthquake

Once the earthquake subsides, it’s important to proceed with caution and take the following measures:

Administer First Aid

Attend to individuals with minor injuries using first aid kits. For those with more severe injuries, it’s essential to wait for professional medical help and avoid moving them until it is safe.

CPR and Rescue Breathing

If someone is not breathing, administer rescue breathing. If the person has no pulse, perform CPR (cardiopulmonary resuscitation) until medical assistance arrives.

Be Mindful of Hazards

Attend any tumbling shelves or falling items and be cautious around damaged walls made of bricks or other unstable materials. Your safety should be a priority.

Check Gas and Power Connections

Inspect gas valves for leaks and turn off the main power switch if damage is possible. Unplug broken appliances until they can be properly repaired.

Stay Clear of Power Lines

Keep a safe distance from downed power lines and any objects or appliances in contact with them. Electricity poses a significant risk, so exercise caution.

By following these guidelines, you can ensure your safety and the well-being of those around you during and after an earthquake. Remember, preparedness and knowledge are key to effectively managing these natural disasters. Stay informed and stay safe!

Enhancing Preparedness with Disaster Management

In times of uncertainty, being equipped with the knowledge and strategies to navigate through natural disasters is crucial. In this section, we present an insightful video that sheds light on the broader concept of disaster management and its significance during both predicted and unpredictable calamities.

What are the Effects of an Earthquake?

Earthquakes can have a wide range of effects, varying in severity depending on factors such as the quake’s magnitude, the depth of its epicentre and the local geology. Here are some of the primary effects caused by earthquakes:

Ground Shaking: When an earthquake occurs, the release of energy creates seismic waves that cause the ground to shake. The intensity of the shaking can vary depending on factors such as the magnitude of the earthquake, the distance from the epicentre and the local geology. Areas closer to the epicentre usually experience more intense shaking, which can significantly damage structures and infrastructure.
Damage to Man-Made Structures: One of the most noticeable effects of an earthquake is the damage it can cause to buildings, bridges, roads and other man-made structures. The shaking can lead to structural failure, collapse and extensive damage, especially if the buildings are not designed or constructed to withstand seismic activity. The severity of the damage depends on factors such as the quality of construction, adherence to building codes and proximity to the epicentre.
Fires and Hazardous Chemical Spills: Earthquakes can trigger secondary hazards, such as fires and hazardous material spills. The violent shaking can rupture gas pipelines, damage electrical systems and disrupt infrastructure, leading to the ignition of fires. Additionally, earthquakes can cause the release of hazardous chemicals stored in industrial facilities, posing risks to human health and the environment. These secondary effects can further exacerbate the impact of an earthquake and complicate rescue and recovery efforts.
Landslides and Avalanches: In areas with steep slopes or unstable terrain, earthquakes can trigger landslides and avalanches. The shaking can destabilize slopes, causing rocks, soil and debris to slide downhill. Landslides can damage structures, block roads and even bury entire communities, leading to additional casualties and hindering rescue and relief operations access.
Tsunamis: Underwater earthquakes can generate tsunamis, particularly those occurring along tectonic plate boundaries. These massive ocean waves can travel long distances, reaching coastal areas and causing devastating flooding. Tsunamis pose a significant threat to coastal communities and can result in widespread destruction and loss of life.

Understanding the potential effects of earthquakes is crucial for implementing appropriate mitigation measures and developing effective disaster response plans. It is important to note that these are just some of the effects that earthquakes can have. The severity and extent of these effects depend on various factors, including the earthquake’s characteristics, the impacted area’s location and the affected communities’ preparedness and resilience.

Understanding Seismograph and the Richter scale

A seismograph and the Richter scale are essential tools used in seismology to understand and characterise earthquakes. While they are related to each other, they serve different purposes. Here’s an elaboration on the difference between a seismograph and the richter scale.

Seismograph

A seismograph is a device used to measure and record the vibrations or ground motions caused by earthquakes.
It consists of a ground motion sensor, typically a mass attached to a fixed base and a recording system that captures the movements detected by the sensor.
Seismographs are essential in monitoring seismic activity, as they provide valuable data about the intensity, duration and frequency of ground shaking.
By analyzing the recorded seismograms, scientists can determine various characteristics of an earthquake, such as its magnitude, location and focal depth.
Seismographs also detect other seismic events, such as volcanic eruptions and underground explosions.

Richter scale

The Richter scale, developed by Charles F. Richter in the 1930s, is a numerical scale used to quantify the magnitude or strength of an earthquake.
It measures the energy released during an earthquake by analyzing the amplitude of seismic waves recorded on seismographs.
The Richter scale is logarithmic, meaning that each whole number increase on the scale corresponds to a tenfold increase in the amplitude of the seismic waves and approximately 31.6 times more energy released. For example, a magnitude six earthquake releases about 31.6 times more energy than a magnitude five earthquake.
The Richter scale provides a standardized measurement for consistent comparison of worldwide earthquake magnitudes.

Difference Between Seismograph and Richter scale

In summary, a seismograph is a device used to measure and record the ground motions caused by earthquakes. The Seismograph provides the data necessary to calculate the magnitude of an earthquake, which is then represented on the Richter scale. At the same time, the Richter scale is a numerical scale used to quantify the energy released during an earthquake. Together, these tools help seismologists and scientists better understand and characterise seismic events, enabling them to assess the impact and potential hazards associated with earthquakes.

Effects of Earthquake

Earthquake is one of the worst natural disasters . It causes a catastrophe. But do you know why do earthquakes occur? What are its after-effects? Let’s find out more about it.

Introduction to Earthquake

An earthquake is a sudden shaking movement of the surface of the earth . It is known as a quake, tremblor or tremor. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities. The seismicity or seismic activity of an area refers to the frequency , type and size of earthquakes experienced over a period of time.

So far, there have been sixty-two earthquakes in India. The first recorded earthquake in India was on 6th June 1505 it occurred in Saldang, Karnali zone. And the most recent one happened in India as on 31st January 2018 and occurred in Kashmir, Pakistan, Afghanistan, and Tajikistan.

An earthquake is measured on Richter’s scale. A seismometer detects the vibrations caused by an earthquake. It plots these vibrations on a seismograph. The strength, or magnitude, of an earthquake, is measured using the Richter scale. Quakes measuring around 7 or 8 on the Richter scale can be devastating.

Learn more about Shape of Earth here in detail.

Causes of Earthquake

Earthquakes are caused by sudden tectonic movements in the Earth’s crust. The main cause is that when tectonic plates, one rides over the other, causing orogeny collide (mountain building), earthquakes. The largest fault surfaces on Earth are formed due to boundaries between moving plates.

The stress increases when they stick, relative motion between the plates. This continues until the stress rises and breaks, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy as shock waves. Such faults are San Andreas fault in San Francisco, Rift valley in Africa etc.

The effects of an earthquake are terrible and devastating. Many building, hospitals, schools, etc are destroyed due to it. A lot of people get killed and injured. Many people lose their money and property. It affects the mental health and emotional health of people.

The environmental effects of it are that including surface faulting, tectonic uplift and subsidence, tsunamis, soil liquefaction, ground resonance , landslides and ground failure, either directly linked to a quake source or provoked by the ground shaking.

Due to this, we can feel the entire ground shaking below our feet. This can cause buildings, trees and other tall structures to break and fall.
The strength or intensity of an earthquake is called its magnitude and it is measured on the Richter scale from 1 to 10.
Earthquakes can be measured using a seismograph.
Earthquakes of 6 or 7 magnitude are very strong and can cause massive loss of life and property.
The exact spot where an earthquake originates is called its epicentre. This place faces the maximum effect of the disaster.
People living in earthquake-prone areas must always be prepared to face the danger and have a disaster management strategy as it is difficult to predict an earthquake.
The best way to ensure safety during an earthquake is to run to open fields.
If there is no open space nearby, you can duck under a strong and sturdy table.

Short paragraphs on earthquakes help students to weave their essays around them. They guide the children on how to form sentences. A short paragraph on earthquakes is given below for the reference of the kids:

Earthquakes are caused by the shaking of the earth, which occurs when two of the earth’s tectonic plates slide over each other. These can be caused by natural factors such as volcanic eruptions or man-made factors such as mining or the construction of various structures. Some earthquakes have little or no effect, while others cause widespread devastation. There have been numerous earthquakes in the past that have resulted in significant loss of life and property. During an earthquake, it is recommended that we run out of our home and move to an open and safe location. We cannot predict earthquakes, but we can ensure safety with proper precautions.

Since earthquakes are a common phenomenon, knowing about them is crucial. Given below is an example of a short essay for classes 1, 2 and 3:

An earthquake is a natural disaster which is caused by the shaking of the earth. The main reason for this is the movement of tectonic plates. Tectonic plates are fragments of the earth’s surface plates that float in the core. When these plates begin to drift away from each other or begin to slide towards each other, tremors occur, resulting in earthquakes. An earthquake can also be induced by a volcanic eruption or man-made factors such as mining and the construction of concrete structures. It can also cause fires, tsunamis, and other natural disasters.

Areas closer to the continental shelf, such as Mumbai, Srinagar, Kolkata, and Chennai, are more vulnerable to earthquakes. The impact of an earthquake on a location is determined by how far it is from the epicentre. The magnitude of an earthquake is measured on the Richter scale. Higher magnitude events are less common but cause more damage to people and property.

Earthquakes sometimes cause a huge loss of life and property, making it essential for children to learn about them. Writing an essay on earthquakes makes them aware of its causes, effects and even precautions that one should take. Given below is a long essay for class 3 that can help students learn more about this natural calamity:

What Is An Earthquake?

An earthquake is the movement within the earth’s crust due to the sudden release of energy from the earth’s interior. It results in massive loss of lives and affects that area’s infrastructure. The damage caused depends on the intensity of the earthquake.

What Are The Types Of Earthquakes?

Earthquakes can be categorised into four types based on the cause of occurrence:

Tectonic Earthquakes: These earthquakes occur when the floating tectonic plates on the earth’s core either move away from each other or slip towards each other, causing friction. As a result, pressure from the ground is released, causing tremors.
Volcanic Earthquakes: Volcanic eruptions cause these earthquakes. Magma movement causes pressure and changes in the rock surrounding the magma, resulting in earthquakes.
Collapse Earthquakes: These are low-intensity earthquakes caused primarily by mining. Underground blasts in mines are a major cause of mine collapse, resulting in collapse earthquakes.
Explosive Earthquakes: These earthquakes are typically caused by explosions caused by nuclear bomb testing.

What Are The Causes Of Earthquakes?

An earthquake is a natural disaster; hence, it is generally caused naturally. However, there are undoubtedly other reasons too that can cause earthquakes like:

Volcanic Eruptions: Volcanic earthquakes are the result of volcanic eruptions. It’s a common cause of earthquakes, and areas with active volcanos are more vulnerable to such earthquakes.
Human Activities: Natural and man-made activities can both cause earthquakes. Human activities that can cause earthquakes include the construction of concrete structures, mining, and nuclear bombing.
Geological Factors: These occur when tectonic plates shift away from their original position, causing friction and, as a result, earthquakes.

What Are The Effects Of Earthquakes?

An earthquake has numerous effects, such as:

Death and property destruction is one of the effects of an earthquake. On the other hand, the magnitude of the destruction is determined by the magnitude of the earthquake and its distance from the epicentre.
Earthquakes can also spark fires in electric and gas pipelines, resulting in huge losses.
Tsunamis are sometimes caused by an earthquake, causing even more damage to people and property.
Earthquakes can also cause large structures and monuments to collapse, causing irreparable damage.
Landslides are another significant impact of earthquakes. Landslides, which result in the fall of large rocks, are common in hilly areas. They can also cause traffic congestion.

Precautions To Be Taken During An Earthquake

Even though earthquakes are not predictable, there are certain precautions that we can take to lessen their impact, such as:

Avoid enclosed spaces: Get out of your building as soon as you feel a tremor and find an open space.
Avoid using the lift: It is always advisable to avoid using the lift while evacuating the building during an earthquake because it can be dangerous.
Avoid trees and lampposts: If you’re driving, never park your car and stand beneath a tree or a lamppost because the earthquake could cause it to fall.
If you cannot move, try crouching beneath a sturdy table or bed to protect yourself from falling objects.

This earthquake essay will give your child a general understanding of the subject while also making them aware of their surroundings. It will also help kids learn about the precautions to take during an earthquake, so they know what they should to if it happens again.

Some of the interesting facts about earthquakes for children are:

Earthquakes can occur for natural or man-made reasons.
An earthquake cannot be predicted in advance.
Seismology is the study of earthquakes. The Richter scale is a device used to measure earthquake intensity.
The greater the intensity on the Richter scale, the more severe the damage.
Earthquakes can be so devastating that they can cripple an entire economy.

1. Can We Forecast Earthquakes?

No. No such technology has allowed seismologists to predict an earthquake in advance.

2. How Is Earthquake Measures?

The intensity of an earthquake is measured on a Richter scale.

3. Which Are The Earthquake Prone Areas In India?

Several earthquake-prone areas in India include Srinagar, Mumbai, Patna, Kolkata, Chennai, Delhi, Guwahati, Pune, Kochi, and Thiruvananthapuram.

Earthquakes are major natural disasters that have caused irreparable damage in the past and will do so in the future. We cannot prevent them, but we can aim to mitigate their effects with proper precautions.

Short Essay on Earthquake – Essay 1 (200 words)

Earthquakes occur suddenly, usually without any warning signs, and can cause huge destruction. Though there is a separate branch of science referred to as seismology that study about earthquakes and tries to predicts their occurrence however, it doesn’t help in determining the exact time or date of this natural calamity.

Scientists around the world constantly try to predict the occurrence of earthquakes. While seismology department does warn against Earthquake in certain areas in future however it is unable to find out as to when exactly it would occur.

As it is said, little knowledge is dangerous hence lame predictions about earthquakes do more harm to the people than good. People begin to live in constant fear of earthquake. Panic among people living in such areas can be seen clearly as they can hardly do much about safeguarding themselves from the possible destruction caused due to this natural calamity.

However, earthquakes aren’t always severe and destructive. At times, these are small and mild. Sometimes, these are so mild that people do not even get to know that these have occurred. However, even at the slightest of tremors, it is suggested to evacuate the buildings and come out in an open area to ensure safety.

Essay on Earthquakes and Volcanoes – Essay 2 (300 words)

Introduction

Earthquakes and volcanoes are two natural calamities that occur due to the changes in the surface of Earth. Man has little or just no role in bringing about these natural disasters. Earthquakes and volcanoes are said to be interrelated. It has been observed that volcanic regions are more prone to earthquakes that often serve as a warning sign of an impending volcano.

Earthquake is basically the shaking of the Earth. Earthquakes either occur due to the movement of tectonic plates under the Earth’s surface or because of the movement of magma in volcanoes. The ones caused due to magma movements may be followed by volcanic eruptions. Earthquakes can be weak as well as violent. While the weak volcanoes are hardly felt, the violent ones can result in the devastation of big buildings and huge loss of life. Numerous earthquakes have occurred in different parts of the world causing severe destructions.

Volcano is the eruption of hot lava from the surface of Earth. It occurs when the Earth’s crust ruptures. Hot lava, poisonous gases and volcanic ash come out by way of volcanic eruptions and can cause vast destruction. Different types of volcanoes include super volcanoes, sub-glacial volcanoes, underwater volcanoes and mud volcanoes.

What is Volcanic Earthquake?

Volcanic earthquake also known as volcano tectonic earthquake is caused due to the movement of magma. This movement exerts pressure and causes changes in the rock around the magma and this eventually leads to volcanic earthquake. These earthquakes are known to cause major destruction that may include ground deformation, uprooting of buildings and ground cracks.

Both earthquakes and volcanoes may result in severe loss for the mankind. While scientists try their best to predict both of these, they haven’t been successful in determining the time and date for these natural disasters. People living in earthquake and volcano prone areas must stay vigilant and be prepared to face these and should act calmly and wisely if such a problem occurs.

Essay on Types, Causes and Effects of Earthquake – Essay 3 (400 words)

Earthquakes are caused due to the movement of magnum or tectonic plates under the Earth’s surface. They may vary in severity, time and other factors. Earthquakes have been classified into various categories. The effect they cause varies based on their type.

Types of Earthquake

There are different types of earthquakes that have been experienced on our planet. Here is a look at the main types of earthquakes:

Tectonic Earthquake

A tectonic earthquake is an outcome of the breakage of Earth’s crust because of exertion of pressure on rocks and tectonic plates.

This is often a mild earthquake that takes place in the same area that has been hit by a severe earthquake few hours, days or weeks before.

A small earthquake that takes place before a severe earthquake is referred to as a foreshock.

Explosion Earthquake

This type of earthquake occurs because of explosion of a chemical and nuclear device.

Volcanic Earthquake

It is an earthquake that occurs due to the combination of tectonic forces and volcanic activities.

Collapse Earthquake

This type of earthquake is caused due to the explosion of rocks. These are generally mild earthquakes that occur due to mining activities.

Submarine Earthquake

It is an earthquake that takes place underwater particularly at the bottom of an ocean. It is commonly referred to as Tsunami.

Causes of Earthquake

An earthquake basically is an outcome of the movements of tectonic plates beneath the Earth’s surface. However, these are also caused due to certain other reasons. These are mostly natural reasons however sometimes these can even be man-made. Given below are the various causes of earthquakes:

Volcanic Eruptions

Volcanic eruptions are a common cause of earthquake. Areas that are faced with frequent volcanic activities are more prone to earthquakes.

Geological Fault

It occurs because of the displacement of plates from their original position. As the rocks move alongside these planes, it brings about tectonic earthquakes.

Human Activities

Man is known to influence various natural activities and earthquakes are no exception. Nuclear bombing, building of dams and mining are few such human activities that can cause earthquake.

Effects of Earthquake

Mild earthquakes are harmless however the violent ones can cause mass destruction. Numerous lives are lost, several people are injured and many houses and other buildings are devastated during this natural calamity.

Earthquake is a dangerous natural calamity that has caused huge damage in various parts of the world. It cannot be avoided as the scientists are not able to predict its occurrence accurately.

Long Essay on Earthquake Management – Essay 4 (500 words)

Earthquake is a natural calamity which is capable of causing vast destruction and there is no way to stop it from occurring. Our planet has been hit by a number of strong earthquakes of different magnitudes that have led to the loss of many innocent lives and heavy damage to the property. A need for disaster management for earthquake was felt owing to the huge and frequent damage they had been causing around the world.

Earthquake Management

The seismic department studies earthquakes. The department monitors the environment and the activities that occurs under the Earth’s surface in an attempt to predict earthquakes and their severity. However, it has largely failed in predicting the exact date and time of occurrence of the earthquake.

Since it is almost impossible to forecast and avoid the occurrence of earthquakes, we must prepare ourselves to lower the losses caused by these. Japan for instance is highly prone to earthquakes. However, their preparedness to handle this natural calamity ensures little or no damage to property and life in the country.

The recent earthquakes that jolted India have shown how under-prepared we are to handle this natural calamity. A need to build an environment which is earthquake resistant has been felt. Though, this cannot be full proof however efforts in this direction can certainly help bring down the magnitude of losses.

Extensive research is going on in this direction. Builders are being encouraged to build earthquake resistant structures. Special degree in Earthquake Engineering is being imparted to prepare our future generations to tackle this natural disaster smartly. Structural Earthquake Engineering, Geo-technical Earthquake Engineering, Remote Sensing and Seismology are the fields that are being explored and taught.

Do not Panic during an Earthquake

It is but natural to panic during any difficult situation however doing so only worsens the problem. We must thus not panic during earthquake. We should rather act wisely. Here are few things you can do to lower the possibility of disaster:

Come out of your house/ office/ shop and gather in an open place.
Do not use elevator. Take the stairs to go down.
Make sure you are at a safe place as you come out and not somewhere where there is a possibility of falling objects or collapsing building.
Get under a table or bed if you cannot move out.
Stay calm and don’t indulge in negative talks.
Help those caught inside or in need if you can.

Earthquake: Precautions to be taken

People living in earthquake prone areas must stay alert and prepared to handle this natural disaster at all times. Here are certain things that they must keep handy:

Necessary medicines
Canned packaged food
Camp stoves that can be installed outdoors
Enough drinking water
Sanitation stock
Cash/ Debit card/ Credit Card
Important Certificates/ documents

It is a good idea to prepare a bag that can be carried easily in case of emergency.

The government must take measures to ensure the destruction caused by this natural calamity is lowered. In case of a severe earthquake, the government must take measures to help people who lose their houses and other important belongings. The government must be prepared to handle such an emergency situation efficiently so that people do not suffer further.

Long Essay on Earthquake in India – Essay 5 (600 words)

Earthquakes occur when the tectonic plates shift and climb over one another. This leads to mountain building referred to as orogeny which is the cause of severe earthquakes. Thus, the tectonic plates that lie under the surface of Earth are responsible for this natural calamity. Just like many other parts of the world, India has also experienced numerous earthquakes in different areas. While some of these have caused serious destruction others have largely gone unnoticed.

Major Earthquakes in India

Our country has suffered from some major earthquakes in the past that have led to severe damage and immense panic among people. Some of the major earthquakes experienced in India are as follows:

The Hindu Kush Earthquake (26 October 2015) : This was a magnitude 7.5 earthquake that caused vast destruction in South Asia. Jammu and Kashmir in India was jolted by this quake and tremors were felt in many other parts of Northern India. With its epicentre in Afghanistan, the quake caused tremendous destruction in the country as well as in its neighbouring country Pakistan. Statistics reveal that 399 people lost their lives and as many as 2539 were injured during this earthquake.

The May 2015 Nepal Earthquake : Yet another severe earthquake in Nepal that led to havoc in India too as strong tremors were felt in various parts of our country including Uttar Pradesh, Bihar, and Delhi. With its epicentre in Dolakha and Sindhupal Chowk, Nepal it was a 7.3 magnitude earthquake. Considered to be an aftermath of the April 2015 earthquake, it took away 218 lives and injured more than 3200 people.

The April 2015 Nepal Earthquake : This is said to be one of the major earthquakes that has ever occurred in the recent times. It was a 7.8 magnitude earthquake. The epicentre of this earthquake was Gorkha District in Nepal however strong tremors were felt in various parts of India too. It led to the devastation of many buildings and took as many as 9,000 lives. 22,000 people were injured during the event.

Bhuj Earthquake (26 January 2001): This was one of the most devastating natural calamities that ever hit our country. The earthquake with a magnitude of 7.7 lasted for more than 2 minutes and wrecked havoc on the beautiful Indian state of Gujarat. Numerous buildings were devastated as a result of this earthquake. It killed around 20,000 people and injured as many as 167,000 people.

The Latur Earthquake (30 September 1993): The Latur earthquake hit the Indian state of Maharashtra. This 6.2 magnitude earthquake mainly affected the districts of Latur and Osmanabad. It demolished as many as 52 villages in Maharashtra and killed around 10,000 people. As many as 30,000 people were injured during the event.

Uttarkashi Earthquake (2 nd October 1991): The earthquake with a 6.8 magnitude hit Gharwal and Uttarkashi in Uttrakhand. Strong tremors were felt in these two regions and various other parts of Uttar Pradesh. It caused mass destruction. Numerous buildings were wrecked during the event. More than 700 people lost their lives and numerous others became homeless.

Earthquake Prone Areas in India

Almost every part of India has been hit by earthquake at some point or the other. While some areas in the country are highly prone to earthquakes others stand a low chance of being hit by them. Some of the earthquake prone areas in the country include Srinagar, Mumbai, Delhi, Guwahati, Pune, Kolkata, Chennai, Patna, Kochi and Thiruvananthapuram. All these regions have felt strong tremors of earthquake in the past and stand a high chance of experiencing the same in future as well.

India has seen major destruction due to earthquakes. Many buildings have been damaged and several people have lost their lives due to this natural calamity. We wish and pray to God that such strong tremors don’t occur in future.

Long Essay on Earthquake – Essay 6 (800 Words)

An earthquake is a tremor that is produced when two surfaces of earth, underneath the surface, slip against each other and release seismic waves. Thus, an earthquake implies a sudden release of energy from within the earth, which takes the form of tremors, generally called earthquake. World over, around fifty thousand earthquakes occur annually, but only about hundred of them are potentially dangerous. Little was understood about them until the 20 th century, when Seismology was introduced as a study of earthquakes. In the following essay we will go through the causes, effects and facts about earthquakes.

Causes of Earthquakes

Earthquakes are caused by the movement or breaking of rocks underneath the surface of earth. Under earth’s surface layers of rocks stay connected to each other. The rocks or plates push each other continuously, but doesn’t move as the forces balance each other.

However, if the rocks break or layers move against each other, seismic waves are produced which reach the surface in form of tremors known as earthquake. Hence earthquake is felt as long as the rocks are rubbing against each other and ceases as soon as the rocks get stuck again. In seismic language, the point immediately below where the rocks break is called the focus and the point immediately above is called the epicenter.

Measurement

The severity of an earthquake is measured in Richter scale. A strong earthquake has a high value on Richter scale while a low earthquake has a lower value.

An earthquake which measures 6 to 7 on Richter scale is potentially damaging to life and property, while the effects of earthquake measuring 4 to 5 on Richter scale could result only in mild tremors or a little structural damage.

There are many effects of earthquake and may include the following; though, they are not limited to the effects mentioned here below-

1) Tremors or Shaking

Shaking of ground is the first effect of earthquake and is also the most damaging one. The severity of shaking; however, depends on the magnitude of earthquake and the distance of the place from the epicenter. An earthquake measuring around 6 or above on Richter scale has an ability to destroy even the most strongest of buildings, depending on their proximity to the epicenter.

2) Ground Rupture

Sometimes, an earthquake measuring high on Richter scale could cause visible rupture in the ground along the fault line. Sometimes, when the earthquake is potentially high on Richter scale, a ground rupture measuring several meters deep and several kilometers long, may result. Such ground ruptures are considerably harmful to significant structures like dams, nuclear power stations and bridges.

Earthquakes can cause forest fires, as tremors force the trees to rub each other, thereby generating heat and sparks. There have been forest fires recorded after earthquakes. Moreover, an earthquake can cause fire in urban areas also, by rupturing electrical lines and damaging electrical protection systems.

4) Landslides

Landslides are the most common aftereffects of earthquake in hilly areas. Shaking of earth displaces the soil on sloppy hills, resulting in a landslide. The landslides sometimes could be potentially more dangerous than the earthquake itself, as they contain debris like trees and rocks, and have a high potential to damage life and property.

Tsunami is the most severe and frightening aftereffect of earthquake. Tsunami is caused when the epicenter of an earthquake lies under the ocean surface. An earthquake in the sea bed results in waves those are not more than a ripple over the epicenter, but as they travel towards the shore, they get bigger, faster and stronger. A wave only measuring 1 meter above the epicenter could measure 100 meters at the shores, resulting in huge loss of life and tremendous damage to the property.

What to do in an Earthquake?

Though the science of studying earthquake has developed significantly, and today it’s possible to forecast an earthquake, even then it might not be possible in every place and situation. Below given are some of the safety precautions you could take when caught in a situation, to save yourself and family from harm.

Situation 1 – Outdoors

If you are outdoors and sense an earthquake, move away from buildings, poles, trees as fast as you can. The greatest danger is immediately outside of a building and near boundaries. When caught outside in an earthquake it’s wise to stand still on a clear ground, away from any structure that could fall upon you.

Situation 2 – Indoors

If you are caught in an earthquake inside a building, the best option for you would be to find some sturdy and strong table or bed and lie down below it, ducking your head under your arms. Stay put in this position until the tremor ceases or help arrives.

Situation 3 – Driving a Vehicle

If you are driving and sense an earthquake, then move as fast as possible from buildings and other high structures and stay inside the vehicle. Even after earthquake, proceed cautiously and avoid bridges if possible, as the tremors might have damaged them.

Earthquakes are a natural phenomenon and despite our knowledge on them, we cannot stop them from occurring; nevertheless, we can always act wisely when caught in the situation, saving our life as well as life of others.

What is an Earthquake?

Last updated at April 16, 2024 by Teachoo

Sudden shaking or trembling of earth is called Earthquake.

It lasts for a very short time.

It is caused by deep disturbance within the earth's crust.

Damages caused by Earthquake

Damage to building and property.

Many buildings, dams,bridges are damaged because of earthquake

Loss of Life

Many plants, animals and human beings die because of earthquake

Cause Floods, Tsunamis,Landslides

Earthquakes cause sea level to rise causing Tsunamis

Earthquake in mountain areas may cause rocks to fall causing landslide

How are Earthquakes Caused?

It is caused by brushing or collision of different plates of earth's crust.

This brushing or collision cause disturbance which leads to earthquake

Explanation

Earth has different layers like inner core, outer core, mantle and crust.

The outermost layer is called the crust

The crust is not in one piece

It is fragmented into different parts

These parts are called plates

These plates are not stationary(they keep on moving)

When one plate comes near another plate, it either collides with it or brushes apart

This brushing or collision causes disturbance which leads to earthquake

Note : Tremors on earth can also be caused when a volcano erupts or a big meteorite hits the earth or an underground nuclear explosion is carried out.

Earthquakes

We know what earthquakes are and how they are caused. More details after long research has been found about the earthquakes.

Somewhere under the earth’s crust a strata fractures and crumbles down. As it breaks it strikes against the rocks around it and causes quakes to travel out in all directions. The impact of the explosion radiates waves of shock in all directions. The shock waves strike the earth’s crust and make the earth tremble or quake. The quake lasts only for a few seconds. But within these fleeting moments terrible havoc is caused to life and property.

The quakes differ in intensity; mild shocks pass off lightly. Severe shocks cause great damage and terrible suffering. In 1923, two Japanese cities, Tokyo and Yokohama were struck and about 250,000 people were killed and several crores of rupees worth of properties were destroyed.

If the shock is severe, great changes in the earth’s crust occur. The land on either side moves up or slips down. Portions of sea floor rises up to form dry land-Sea beds rise up making the sea shallow. Tracts of land become suddenly elevated or depressed or even submerged. Rocks and boulders on mountain sides are loosened setting up a land slide. If the quake occurs in the mid sea, great waves are set up. The waves spread destruction along the neighbouring shores.

The spot where the quake occurs and from where shock waves radiate is known as the Epicenter. The shock waves are transmitted over thousands of kilometres all around. Now it is possible to get warnings of an impending shock even some days in advance through, instruments called the Seismograph and seisnnoscope.

The Japanese who often suffer from earthquakes build their houses with light materials like bamboo. They have now evolved shock proof houses also.

The earthquake belt run around the earth along the Pacific Ocean, the Himalayas and its branches, Quetta, Baluchistan, Cutch, Bihar, Assam, Peru, Burma, the East Indies, Japan, New Zealand, Peru and Chile.

Karnataka State Syllabus Class 8 English Supplementary Chapter 2 The Earthquake

The earthquake questions and answers, summary, notes.

I. Answer each of the following in a sentence or two:

Question 1. What was the wild imagination of the hare? Answer: The hare imagined that the earth was falling to pieces around him.

Question 2. Which event caused the crash? Answer: A huge ripe bel fruit fell right on top of the palm shrub.

Question 3. Name a few animals that joined the race. Answer: Hares, deer, boars, antelopes, buffaloes, gazelles, rhinoceroses, tigers and elephants.

Question 4. Which of the animals do you think was the sensible one? How do you justify that? Answer: The lion was the sensible animal. It knew that there wasn’t any earthquake. And the animals had misunderstood some sound for an earthquake.

Question 5. What did the lion guess about the cause of the crash? Answer: The lion guessed that there was no doubt it was a ripe bel fruit fell from above on to the palm leaf and made the crash.

Question 6. What was the command given by the lion to the animals at the end? Answer: The lion told the animals that there was neither an earthquake nor any other calamity. It ordered them to go back to their places and live peacefully.

II. Write the answers for each of the following in about 50-60 words.

Question 1. It is said: ‘The mob cannot think’. Do you agree? If so, how does this story illustrate that? If you do not agree with the statement, how do you explain the behaviour of the animals? Answer: Yes. I agree with the statement. In the story the hare misunderstands the sound of the bel fruit falling on a palm shrub for an earthquake and starts running to save its life. Hares and other animals believe what the other animals had said and joined the stampede towards a safe place. In a mob, the group mentality prevails over individual judgment. The majority cannot go wrong is belief. So, without making sure that there has been an earthquake really, the animals rush towards a safer place to save their lives. No. I do not agree with the statement. When there is a threat to life, the instinct is to run away from the danger area and be safe.

Question 2. Sum up what the lion did to verify the statement of the hare. Answer: The lion guessed what might have happened. But, it wanted to make sure. It asked the other animals to stay there until it came back. It asked the hare to sit on its back and ran towards the palm trees. The lion examined the place and found the bel fruit which had fallen on the palm shrub. It returned to the place where the other animals were waiting. It assured them that there was no reason to fear. It ordered them to go back and lead their normal lives.

Very long ago, near the Western Sea, a hare lived in an earth hole under a small palm shrub at the foot of a bel tree. One day, as he was bringing food to his earth hole, a strange fear entered his mind. He thought what would become of him if the earth were to fall to pieces. At that very moment, a huge ripe bel fruit fell on top of the palm shrub. The hare was sure that the earth was falling to pieces around him. He started running without looking back. Another hare saw him running and asked why he was terrified and running like that. The hare told the second hare that the earth was falling to pieces behind them.

So, the second hare ran after him. Similarly, each and every hare followed suit. Soon a hundred thousand hares were all fleeing after him. Then a deer, a boar, an antelope, a buffalo, a gazelle, a rhinoceros, a tiger and an elephant saw the hare one after the other. After they were told that the earth was falling to pieces, they also ran after him. Gradually the whole race of each species joined the mad race towards safety.

Then a huge lion saw the wild flight of animals. He asked them what the matter was. When he was told that the earth was falling to pieces, he thought, there wasn’t any question of an earthquake. He was pretty sure that the animals had misunderstood some sound they had heard. He decided to find out the truth and save all the animals from destruction.

The lion ran to the foot of the hill, stood before the animals and roared thrice. All the animals were frightened. They huddled up together. The lion asked them the reason for their running. They all said that the earth was falling to pieces. He asked who had seen that. Some said the elephants knew about it. When he asked the elephants, they said the tigers knew it. In this way each and every animal said it had not seen it. Finally, the hare, which started the commotion, was asked. The hare said that it was true. The lion wanted to know where the hare was at that time.

The hare replied that he was resting under a palm leaf at the foot of a bel tree near the Western Sea. The lion guessed what might have happened. A ripe bel fruit had fallen from above on to the palm leaf and made some noise. The hare must have thought that the earth was cracking up and fled. The other animals without bothering to confirm had run after him.

The lion decided to find out. It ordered all the animals to stay where they were until he returned. He asked the hare to sit on his back and lead him to the place. The hare took the lion near the bel tree and showed him the spot. The lion found a ripe bel fruit near the place and there was no sign of an earthquake. The lion and the hare returned to the place where the other animals were waiting. The lion assured them saying that there was neither an earthquake nor any other kind of calamity. It told them not to be afraid of anything but to go to their place and live as they did before. The animals thanked their king and went back to their habitats.

The huge solar storm is keeping power grid and satellite operators on edge

Planet Earth is getting rocked by the biggest solar storm in decades – and the potential effects have those people in charge of power grids, communications systems and satellites on edge.

The National Oceanic and Atmospheric Administration says there have been measurable effects and impacts from the geomagnetic storm that has been visible as aurora across vast swathes of the Northern Hemisphere. So far though, NOAA has seen no reports of major damage.

The Picture Show

Photos: see the northern lights from rare, solar storm.

There has been some degradation and loss to communication systems that rely on high-frequency radio waves, NOAA told NPR, as well as some preliminary indications of irregularities in power systems.

"Simply put, the power grid operators have been busy since yesterday working to keep proper, regulated current flowing without disruption," said Shawn Dahl, service coordinator for the Boulder, Co.-based Space Weather Prediction Center at NOAA.

"Satellite operators are also busy monitoring spacecraft health due to the S1-S2 storm taking place along with the severe-extreme geomagnetic storm that continues even now," Dahl added, saying some GPS systems have struggled to lock locations and offered incorrect positions.

NOAA's GOES-16 satellite captured a flare erupting occurred around 2 p.m. EDT on May 9, 2024.

As NOAA had warned late Friday, the Earth has been experiencing a G5, or "Extreme," geomagnetic storm . It's the first G5 storm to hit the planet since 2003, when a similar event temporarily knocked out power in part of Sweden and damaged electrical transformers in South Africa.

The NOAA center predicted that this current storm could induce auroras visible as far south as Northern California and Alabama.

Around the world on social media, posters put up photos of bright auroras visible in Russia , Scandinavia , the United Kingdom and continental Europe . Some reported seeing the aurora as far south as Mallorca, Spain .

The source of the solar storm is a cluster of sunspots on the sun's surface that is 17 times the diameter of the Earth. The spots are filled with tangled magnetic fields that can act as slingshots, throwing huge quantities of charged particles towards our planet. These events, known as coronal mass ejections, become more common during the peak of the Sun's 11-year solar cycle.

A powerful solar storm is bringing northern lights to unusual places

Usually, they miss the Earth, but this time, NOAA says several have headed directly toward our planet, and the agency predicted that several waves of flares will continue to slam into the Earth over the next few days.

While the storm has proven to be large, predicting the effects from such incidents can be difficult, Dahl said.

Shocking problems

The most disruptive solar storm ever recorded came in 1859. Known as the "Carrington Event," it generated shimmering auroras that were visible as far south as Mexico and Hawaii. It also fried telegraph systems throughout Europe and North America.

Stronger activity on the sun could bring more displays of the northern lights in 2024

While this geomagnetic storm will not be as strong, the world has grown more reliant on electronics and electrical systems. Depending on the orientation of the storm's magnetic field, it could induce unexpected electrical currents in long-distance power lines — those currents could cause safety systems to flip, triggering temporary power outages in some areas.

The storm is also likely to disrupt the ionosphere, a section of Earth's atmosphere filled with charged particles. Some long-distance radio transmissions use the ionosphere to "bounce" signals around the globe, and those signals will likely be disrupted. The particles may also refract and otherwise scramble signals from the global positioning system, according to Rob Steenburgh, a space scientist with NOAA. Those effects can linger for a few days after the storm.

Like Dahl, Steenburgh said it's unclear just how bad the disruptions will be. While we are more dependent than ever on GPS, there are also more satellites in orbit. Moreover, the anomalies from the storm are constantly shifting through the ionosphere like ripples in a pool. "Outages, with any luck, should not be prolonged," Steenburgh said.

What Causes The Northern Lights? Scientists Finally Know For Sure

The radiation from the storm could have other undesirable effects. At high altitudes, it could damage satellites, while at low altitudes, it's likely to increase atmospheric drag, causing some satellites to sink toward the Earth.

The changes to orbits wreak havoc, warns Tuija Pulkkinen, chair of the department of climate and space sciences at the University of Michigan. Since the last solar maximum, companies such as SpaceX have launched thousands of satellites into low Earth orbit. Those satellites will now see their orbits unexpectedly changed.

"There's a lot of companies that haven't seen these kind of space weather effects before," she says.

The International Space Station lies within Earth's magnetosphere, so its astronauts should be mostly protected, Steenburgh says.

In a statement, NASA said that astronauts would not take additional measures to protect themselves. "NASA completed a thorough analysis of recent space weather activity and determined it posed no risk to the crew aboard the International Space Station and no additional precautionary measures are needed," the agency said late Friday.

While this storm will undoubtedly keep satellite operators and utilities busy over the next few days, individuals don't really need to do much to get ready.

"As far as what the general public should be doing, hopefully they're not having to do anything," Dahl said. "Weather permitting, they may be visible again tonight." He advised that the largest problem could be a brief blackout, so keeping some flashlights and a radio handy might prove helpful.

And don't forget to go outside and look up, adds Steenburgh. This event's aurora is visible much further south than usual.

A faint aurora can be detected by a modern cell phone camera, he adds, so even if you can't see it with your eyes, try taking a photo of the sky.

The aurora "is really the gift from space weather," he says.
