Short Essay on Earthquake

The pressure builds up over many years and finally may cause the plates of the crust to move, creating an earthquake. Not all earthquakes cause damage or injury. Most are very mild. About 1,50,00 earthquakes occur each year; but only about one hundred are very destructive.

Every part of the world has earthquakes, but in most places they are not strong. If we mark on a world map, the places where earthquake often occur, our marks will form two large belts, the pacific belt and the Mediterranean belt. The earthquake shakes a building and loosens the bricks in a chimney or wall. The bricks fall, injuring someone or damaging other property. Earthquakes may also break water pipes, cut electric lines and damage gas mains.

Among the worst calamities in India, on 30 th September more than 50 villages around an area of about 70 sq. Seismic activity had registered 6. Earthquakes are generally looked upon as disasters which strike without warming. A significant part of the Himalayan region and some areas in the surrounding of large dams in Maharashtra can be identified as high risk areas.

Once earthquake — prone areas have been identified, it is important to formulate policies which earthquake strikes. People should be given clear region — specific instructions about how they should behave when a quake strikes. Instructions should be in simple language which can be easily understood even by illiterate persons.

For speaking this awareness we should use radio, televisions, newspapers and other mediums. If they know what to do when a quake strikes — even the loss of a few seconds can lead to the loss of life at the time of quake — it will be easy to act without any confusion. This can save a large number of lives. A study of rescue effort revealed that 95 per cent of the trapped people were saved by local people.

Ordinary villagers should be trained in rescue efforts. Construction of high dams, nuclear stations and other high — risk industries should not be established in earthquake — prone areas. Maintaining a green cover will also help to reduce the damage. Rats, snakes, crows, dogs, fish and many other animals are helpful by their changed behaviour to inform about earthquakes beforehand.

A warning before few minutes of earthquake can save thousands of live when an earthquake strikes. More than people were killed in the earthquake event of Latur and Osmanabad districts of Maharashtra on 30 th of September in Earthquake is the result of release of elastic energy after forceful tectonic plate movements. Elastic energy released in the form of seismic or shock waves which travels for a long distance outwards in all directions from the centre point a place of maximum destruction.

High-rise buildings and ancient structures of the cities like Delhi can be badly affected by the seismic force of earthquake. Earthquake is a very dangerous natural disaster which occurs as a sudden shaking movement of rocks in the earth's crust. Some of the earthquakes of low intensity become less dangerous however earthquakes having high intensity become very dangerous and can be extremely violent especially in the areas it occurs.

There is no any fix duration for the occurrence of earthquake, it may occur anytime and anywhere for any duration. It may be brief but repeat many times a day. Earthquake is the result of sudden energy release within the surface of earth.

This released energy under earth crust creates powerful seismic waves which travel through the earth surface. The frequency of waves and type and size of earthquake is measured by the help of seismology which involves the use of seismometer. Large earthquakes may destroy things to a great extent as they take down huge buildings, cause injury and thus death of people. There are various scales used to measure the intensity of shaking and the magnitude of an earthquake.

The scale showing magnitude 3 or less indicates that the earthquake is less harmful however the scale showing magnitude 7 or more causes huge level damage over a wide range of area. Earthquake which occur under the ocean take the form of a tsunami. It is a giant form which can cause death and destruction to the living and non-living things.

High intensity earthquakes give rise to the landslides in the surrounding areas. In the ancient time, people in China were used a device in order to guess the occurrence of earthquake. The device was similar to the jar having dragons on top and surrounded by frogs with open mouths. They guess the occurrence of earthquake by the exchange of fitted ball in dragon's mouth to the frog's mouth.

The direction of earthquake was decided by the position of frog receiving a ball. This device was an effective tool in the ancient time to figure out the origin of an earthquake. A series of earthquake can occur in the variety of earthquake storm whenever earthquake hit a fault in the clusters.

Tsunami is a dangerous form of earthquake which occur as a result of a chain of fast moving waves in ocean because of powerful earthquakes. It is a very serious challenge for the people's lives, safety as well as earthquake engineering as they can engulf coastal areas, swipe away whole city, damage houses and many more.

It is sad to say that it cannot be prevented however people can be warned through various warning systems to run away and save lives. Masters in Computer Application and Business Administration.

Login in to your account. Although earthquakes occur in almost all regions of the earth, they are mainly confined to two well defined belts: This belt is associated with the Circum-Pacific belt of mountain, i.

Nearly 68 per cent of the earthquakes of the world occur here. Nearly 21 per cent of the earthquakes of the world originate in this belt. The earthquakes occur in geologically active areas, mid oceanic ridges and mountain building regions.

The zones where earthquakes occur frequently are known as seismic belts. The belt encircles the Pacific Ocean and more or less overlaps the belt of young mountains and the zone of active volcanoes. In India, earthquakes frequently occur along the foothill zone of Himalayas beginning from Kashmir in the west to Assam in the east.

After , about 15 very destructive earthquakes have occurred in India. The precise prediction about earthquake calamity is elusive though it is not impossible, since for human grey matter sky is the limit.

Recently, the frequency of earthquake calamities in the region has attracted the attention of the scientists all over the world. It has been observed that earthquake may occur and reoccur at the same places and new places but they do not have any regular scale or frequency. The scientists know that elastic strain is piling up along SAF San Andreas Fault since , but they are unable to forecast the exact day, time and place.

In about half of the cases, just before the rocks reach the rupture point to announce the event, small foreshocks announce hours, days or even months before the climax shock, that stress has become critical. The long series of post event tremors indicate adjustments. Sometimes, the break may be as large as the major shock. Unusual animal behaviour, fluctuations of ground water level in wells and springs and variation in the discharge of springs are the phenomena closely related to the development of fractures.

In China, about 90 per cent of the country is lying on the young and restless crust. Chinese have successfully employed most of the precursors in predicting major disasters and have specially mastered the art of closely monitoring and analysing normal behaviour of animals to forecast earthquakes.

The Haicheng earthquake of February , of 7. Active thrust faults exist all across foothills of northern India, the north-east and into northern Pakistan. The subcontinent is sitting on the highly seismic Indian plate, with some major fault lines. In fact, there is no safe zone in India. Of late, the Indian plate boundary has become very active. It is on gradual move, pushing against the Eurasian plate by cm every year.

All the plates of India should have a disaster management authority to deal with any eventuality. Building of laws formulated after Bhuj earthquake to ensure the construction of quake-proof houses have not been implemented by any state government. India is among the few countries with no regulatory mechanism to control building activities.

Disasters have left the years old Qutub Minar with slight tilt, but it has survived several quakes in its life time. The earthquakes are classified on number of bases. Of these the depth of FOCUS, the cause, the intensity and magnitude of earthquakes are very important. The earthquakes are broadly classified into Tectonic and Non- Tectonic types.

The tectonic earthquakes are directly related to the movements of crystal block along faults. They are generally very severe and area affected is often very great. A third way to classify the earthquakes is on the basis of their intensity, which is defined by the effects or degree of damage that an earthquake produces on the structure and features of the earth. This scale of intensity is adopted internationally.

Richter, an American Seismologist, devised the earthquake intensity scale. This is based in the total amount of energy released during an earthquake. The vibrations are recorded on a strip of paper or photograph film and the diagram is produced as shown: Most seismographs contain a heavy weight suspended from a support, which is attached to bedrock.

Essay # 1. Introduction to Earthquake: We know that various forces of nature are responsible for changes in the crust of the earth. Earthquake is a movement of tremor of the earth’s crust. The most recent large earthquake of magnitude or larger was a magnitude earthquake in Japan in (as of October ), and it was the largest Japanese earthquake since records began. Intensity of shaking is measured on the modified Mercalli scostlale.
