Essay on earthquake

Earthquake occurs due to disturbances in the tectonic plates below the Earth’s surface. Earthquakes can be brief and mild or large and destructive. Our planet has suffered many severe and mild earthquakes for centuries.

Earthquakes are mostly brief but can cause mass destruction within seconds. Recently, earthquakes have caused a lot of damage to people all over the world.

Earthquakes occur suddenly, usually without any warning or sign, and can cause massive destruction. Although there is a separate branch of science called seismic that studies about earthquakes and tries to predict their occurrence, it does not help in determining the exact time or date of this natural disaster.

Scientists around the world constantly try to predict the occurrence of earthquakes. Although the seismology department warns against earthquakes in some areas in the future, it is unable to ascertain when exactly it will occur.

As the saying goes, little knowledge is dangerous so lame predictions about earthquakes do more harm than good to people. People start getting scared due to earthquake. Panic can be seen clearly among the people living in such areas because they cannot do much about protecting themselves from the possible destruction caused by this natural disaster.

However, earthquakes are not always severe and catastrophic. Sometimes they are small and light. Sometimes, they are so mild that people do not even know that it has happened. However, even in the slightest setback, it is suggested to evacuate the buildings and come out in an open area to ensure safety.

introduction

Earthquakes and volcanoes are two natural disasters caused by changes in the Earth’s surface. Humans have little or no role in bringing about these natural disasters. Earthquakes and volcanoes are said to be interlinked. It has been observed that volcanic regions are more prone to earthquakes which often act as warning signs of an adjacent volcano.

Earthquake

Earthquake is basically the movement of the Earth. Earthquakes are caused either by the motion of tectonic plates below the Earth’s surface or by the motion of magma in volcanoes. Volcanoes caused by magma movements can occur after an eruption. Earthquakes can be violent as well as weak. While weak volcanoes are rarely felt, violent ones can lead to the destruction of large buildings and heavy loss of life. There have been many earthquakes in different parts of the world which cause severe destruction.

Volcano

A volcano is an eruption of hot lava from the Earth’s surface. This is when the earth’s crust bursts. Hot lava, poisonous gases and volcanic ash move out of the way of volcanic eruptions and can cause huge destruction. Various types of volcanoes include super volcanoes, sub-glacial volcanoes, underwater volcanoes and clay volcanoes.

What is a volcanic earthquake?

A volcanic earthquake is also known as a volcanic tectonic earthquake, it is caused by the movement of magma. This movement creates pressure and causes changes in the rock around the magma and eventually leads to a volcanic earthquake. These earthquakes are believed to cause major destruction which can include ground deformation, uprooting of buildings and ground cracks.

Conclusion:

Both earthquakes and volcanoes can result in serious harm to mankind. Although scientists try their best to predict both, they have not been able to determine the time and date for these natural disasters. People living in earthquake and volcano affected areas should be vigilant and ready to face them and should work in peace and understanding in case of such problem.

Preface:

Earthquakes are caused by the motion of magnum or tectonic plates below the Earth’s surface. They may vary in severity, time, and other factors. Earthquakes have been classified into various categories. The effect due to them varies depending on their type.

Types of earthquake

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

Tectonic Earthquake:  A tectonic earthquake is a result of the rupture of the earth’s crust due to pressure on rocks and tonic plates.

After the shock:  It is often a mild earthquake that occurs in the same area that had been hit by a severe earthquake a few hours, days or weeks before.

Before the shock:  A small earthquake that precedes a severe earthquake is called a foreshadowing.

Explosion Earthquake:  This type of earthquake is caused by the explosion of a chemical and nuclear device.

Volcanic Earthquake:  It is an earthquake caused by a combination of tectonic forces and volcanic movements.

Brief Earthquake:  This type of earthquake is caused by the explosion of rocks. These are generally mild earthquakes caused by mining activities.

Submarine Earthquake:  It is an earthquake that occurs exclusively under water at the bottom of an ocean. This is commonly called a tsunami.

Reason of earthquake

An earthquake is basically a result of the movements of tectonic plates below the Earth’s surface. However, they are also caused by some other reasons. These are mostly natural causes but sometimes they can also be man-made. Given below are the various causes of earthquake:

Volcanic eruptions:  Volcanic eruptions are a common cause of earthquakes. Areas where volcanic movements are frequently encountered are more prone to earthquakes.

Geological faults:  It is caused by displacement of plates from their original position. Since rocks move along these planes, it causes tectonic earthquakes.

Human activities:  Humans are known to affect various natural activities and earthquakes are no exception. Nuclear bombing, construction of dams and mining are some of the human activities that can cause earthquakes.

Earthquake impact:

Mild earthquakes are harmless but can cause violent mass destruction. Many people die, many are injured and many houses and other buildings are destroyed during this natural disaster.

Conclusion:

An earthquake is a dangerous natural disaster that has caused extensive damage in various parts of the world. This cannot be avoided as scientists are not able to estimate its occurrence accurately.

Preface:

An earthquake is a natural disaster capable of causing massive destruction and there is no way to prevent it from happening. Our planet has been affected by many strong earthquakes of different magnitude, which has led to the loss of many innocent lives and caused great damage to property. The need for disaster management for earthquakes was realized due to the huge and persistent losses that have arisen worldwide.

Earthquake disaster management

The Earthquake Department studies earthquakes. The department monitors the environment and the activities under the earth’s surface to estimate earthquakes and their severity. However, it has largely failed to predict the exact date and time of the earthquake event.

Since the occurrence of earthquakes is almost impossible to predict and avoid, we should prepare ourselves to minimize the damage from them. For example, earthquakes are highly likely in Japan. However, their preparedness to handle this natural disaster does little or no harm to property and life in the country.

Recent earthquakes that have shocked India have shown how prepared we are to handle this natural disaster. There is a need to create an environment that is earthquake resistant. However, this may not be absolute proof but efforts in this direction can certainly help reduce the magnitude of the damage.

Extensive researches are going on in this direction. Builders are being encouraged to build earthquake resistant structures. Special degrees in earthquake engineering are being provided to prepare our coming generations to deal smartly with this natural disaster. Structural earthquake engineering, geotechnical earthquake engineering, remote sensing and seismology are areas that are being explored and taught.

Do not panic during an earthquake:

Although it is natural to panic during any difficult situation, doing so only worsens the problem. Thus we should not panic during an earthquake. We should act rather wisely. Here are some things to reduce the likelihood of disaster:

Exit your home / office / shop and gather in an open space. Do not use the lift. Take the stairs to go down. Make sure you are in a safe place as you come out and nowhere where there is a possibility of falling objects or a building falling.

If you can’t go outside then stay under a table or bed. Keep calm and do not indulge in negative conversation.
Help those caught inside or in need if you can.

Earthquake: precautions to be taken

People living in earthquake prone areas should be alert and ready to deal with this natural disaster at all times. Here are some things they should use:

  • Essential medicines
  • Canned Packaged Food
  • Camp stoves that can be installed outdoors
  • Adequate drinking water
  • Hygiene stock
  • Cash / Debit Card / Credit Card
  • Important certificate / document
  • It is a good idea to prepare a bag that can be easily carried in an emergency.

Conclusion:

The government should take measures to reduce the destruction caused by this natural disaster. In case of a severe earthquake, the government should take measures to help those who lost their homes and other important belongings. The government should be prepared to handle such emergencies efficiently so that no more harm is done to the people.

Preface:

Earthquakes occur when tectonic plates shift and climb over each other. It refers to the mountain building as orogeny which is the cause of severe earthquakes. Thus, tectonic plates located below the Earth’s surface are responsible for this natural disaster.

Like many other parts of the world, India has also experienced many earthquakes in different regions. While some of these have caused severe destruction, others have largely gone unnoticed.

Major earthquakes in India:

Our country has suffered some major earthquakes in the past, causing severe damage to people and causing great panic among the people. Some of the major earthquakes in India are as follows:

The Hindu Kush Earthquake (26 October 2015): It was a 7.5 magnitude earthquake that caused widespread devastation in South Asia. Jammu and Kashmir in India was hit by this earthquake and tremors were felt in many other parts of northern India. With its epicenter in Afghanistan, the earthquake caused tremendous devastation in the country as well as in its neighboring country Pakistan. Statistics show that 399 people lost their lives and 2539 were injured during this earthquake.

Nepal Earthquake of May 2015: Yet another severe earthquake in Nepal, which caused devastation in India too, as vigorous tremors were felt in various parts of our country including Uttar Pradesh, Bihar and Delhi. It was a magnitude 7.3 earthquake with its epicenter at Dolakha and Sindhupal Chowk, Nepal. It is believed that after the earthquake of April 2015, it killed 21 people and injured more than 3200 people.

Nepal Earthquake of April 2015: It is said to be one of the major earthquakes in recent times. It was a 7.8 magnitude earthquake. The epicenter of this earthquake was Gorkha district in Nepal but strong earthquake tremors were also felt in different parts of India. It destroyed many buildings and killed 9,000 people. 22,000 people were injured during the incident.

Bhuj Earthquake (26 January 2001): It was one of the most devastating natural disasters that has ever occurred in our country. The earthquake with a magnitude of 7.7 lasted more than 2 minutes and wreaked havoc on the beautiful Indian state of Gujarat. Many buildings were destroyed as a result of this earthquake. It killed about 20,000 people and injured 167,000 people.

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

Uttarkashi Earthquake (2 October 1991): Earthquake of magnitude 6.8 in Uttarakhand and Earthquake in Uttarkashi. Vigorous tremors were felt in these two regions and other parts of Uttar Pradesh. This led to mass destruction. Many buildings were ruined during the incident. More than 700 people lost their lives and many others became homeless.

Earthquake prone areas in India:

Almost every part of India has been hit by an earthquake at some point. While some areas of the country are more prone to earthquakes, others are less likely to be hit. Some of the earthquake prone areas in the country include Srinagar, Mumbai, Delhi, Guwahati, Pune, Kolkata, Chennai, Patna, Kochi and Thiruvananthapuram. All of these areas have experienced strong earthquake tremors in the past and there is a high chance of experiencing the same in the future.

Conclusion:

Earthquake has caused major destruction in India. Due to this natural disaster many buildings have been damaged and many people have lost their lives. We pray to God and pray that such strong shocks do not occur in future.

Preface:

An earthquake is a shock that occurs when two surfaces of the Earth, below the surface, slide against each other and release seismic waves. Thus, an earthquake means the sudden release of energy from within the Earth, which takes the form of an earthquake, commonly called an earthquake.

Worldwide, about fifty thousand earthquakes occur every year, but only about one hundred of them are potentially dangerous. Very little was understood about them until the 20th century, when seismology was introduced as a study of earthquakes. In the following essay we will learn about the causes, effects and facts of earthquakes.

Causes of earthquake

Earthquakes are caused by rocks moving or breaking below the Earth’s surface. The layers of rocks below the surface of the earth are connected to each other. Rocks or plates push each other continuously, but do not move until the forces balance each other.

However, if rocks break or the layers move against each other, seismic waves are generated that reach the surface in the form of shocks known as earthquakes. So the earthquake is felt until the rocks rub against each other and as the rocks get stuck again. In seismic language, the point immediately after the rocks break is called the focus and the point above it is called the subcentre immediately.

Measurement:

Earthquake severity is measured in the Richter scale. A strong earthquake has a high value on the Richter scale while a low earthquake has a low value.

An earthquake measuring 6 to 7 on the Richter scale potentially causes damage to life and property, while an earthquake measuring 4 to 5 on the Richter scale can cause only mild tremors or little structural damage.

Effect of earthquake

Earthquakes have many effects and may include the following; However, they are not limited to the effects mentioned below-

1) Shocks:

Earth shaking is the first impact of the earthquake and also the most damaging. Severity of tremors; However, the intensity depends on the earthquake and the distance of the place from the sub-center. An earthquake of magnitude 6 or higher on the Richter scale has the potential to destroy most buildings, depending on the proximity of the epicenter.

2) Ground breaking 

Occasionally, measuring high earthquakes on the Richter scale can cause ground breaks along the fault line to appear. Occasionally, when earthquakes are potentially higher on the Richter scale, a terrain several meters deep and several kilometers long may break. Such ground breakdowns are quite harmful for important structures such as dams, nuclear power stations and bridges.

3) Fire

Earthquakes can cause forest fires, as shocks force trees to rub each other, creating heat and sparks. Forest fires have been recorded after the earthquake. In addition, earthquakes can also occur in urban areas by breakdown of electrical lines and damage to electrical safety systems.

4) landslide

Landslides are the most common cause of earthquakes in hilly areas. Earth’s shaking displaces soil on muddy hills, resulting in landslides. Landslides can sometimes be potentially more dangerous than earthquakes, because they contain debris like trees and rocks, and have a high potential for damage to life and property.

5) Tsunami

The tsunami is the most frightening and frightening after the earthquake. Tsunamis occur when the epicenter of the earthquake lies below the surface of the ocean. Earthquakes produce waves that are no more than one wave above the sub-center, but as they move toward the shore, they become larger, faster, and stronger.

A wave measuring only 1 meter above the epicenter can measure a distance of 100 meters on the shores, causing great loss of life and property.

What to do during an earthquake?

Although the science of studying earthquakes has evolved greatly, and it is possible to predict earthquakes today, it is still not possible everywhere and in the situation. Given below are some safety precautions that you can take to protect yourself and your family from harm if caught in a situation.

Case 1 – Out

If you are outside and feel an earthquake, move as far away from buildings, poles, trees as you can. The biggest danger is outside a building and near the borders. When caught outside in an earthquake, it is wise to stand on a clear ground away from any structure that may fall on you.

Situation 2 – Indoors

If you are trapped in an earthquake inside a building, the best option for you will be to find and lay down some sturdy and sturdy table or bed, lay your head under your arms. Stay in this position until the trembling stops or help arrives.

Case 3 – Driving

If you are driving and feeling an earthquake, move as fast as possible from buildings and other high structures and stay inside the vehicle. Even after an earthquake, proceed with caution and avoid bridges if possible, as shocks can cause damage to them.

Conclusion:

Earthquakes are a natural phenomenon and despite our knowledge on them, we cannot prevent them from happening; Nevertheless, we can always act wisely when stuck in a situation, saving our lives as well as the lives of others.
