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

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.

Volcanoes

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.

Conclusion

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)

Introduction

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.

  • Aftershock

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.

  • Foreshock

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.

Conclusion

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)

Introduction

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.

Conclusion

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)

Introduction

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 (2nd 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.

Conclusion

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)

Introduction

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 20th 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.

Effects of Earthquake

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.

3) Fires

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.

5) Tsunami

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.

Conclusion

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.
