They believed that earthquake occur whenever mother earth become angry with them. It was Aristotle a great Greek philosopher who made people aware that earthquake occur because of some physical factors.

He told that, some parts of land moves whenever air compressed within the arch escapes which is called as volcanic activity. Earthquake waves cause movement in the surrounding areas because of air pressure and imbalance. Another reason of earthquake occurrence is isostatic adjustment. Earth surface contains some raised and depressed blocks which make balance of earth surface however the balance disturb when blocks moves revolving on units of axis.

Raised blocks get down and cause imbalance on the earth surface which inturn cause earthquake. Generally, it occurs in the volcano prime areas, under the feet of mountains and hills. However, it is not sure that earthquakes do not occur in other places.

Earthquake may occur anytime in any part of the world. Some of the earthquakes become weak however some of them become very strong with huge force which may shake the earth suface far away from the centre point.

Earthquakes with huge intensity become really dangerous and cause severe damage. According to the scientific study with the help of Seismograph, there are some secondary waves and tertiary waves in the earthquake. Himalaya zone, the Ganga, Deccan Plateau, the Brahmaputra valleys, etc are the earthquake prone areas in India.

Kutch Gujarat, India earthquake of the year was so massive calculated 8 on Richeter Scale and affected a huge area around square kilometers depressed by 15 feet and square kilometers raised by 50 feet. 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 also occur at high altitudes and at the mountains that are covered with snow the instability of the earth surface and trembling makes the snow roll down the slope with great speed. It makes impossible to provide relief to the victims.

The earthquakes result in the rupture of gas or petrol pipes thus fire spread and becomes a serious problem as it gets impossible to control such fire. For example in San Francisco earthquake more lives were lost due to fire than due to earthquake. This results due to sand losing its strength and converting to liquid.

This causes buildings and man made structures to sink in and ultimately collapsing upon themselves. Tsunami is a Japanese word meaning long sea waves. Tsunami occurs with earthquake more than 7. Tsunami waves can be as high as meter and can travel to km in 1 hour.

All the coastal area gets logged with water and then results in birth of various diseases. If dams are damages due to earthquake it can result in floods that is flowing of water from water source to land it results in diseases and shortage of potable water.

Due to earthquake and its effects lot of destruction occurs it results in loss of lives, collapsing of buildings and loss of crops. Earthquakes can be stop but its effects can be reduced by taking some preventive measures. Scientists are working to predict earthquake, engineers have designed buildings that can stand a high magnitude earthquake. People are made aware of what to do can they feel shaking of earth. The foremost thing for us is to turn of any source of fire and reach out for open place.

Earth quake is a very natural disaster and you might be asked by your instructor to write an earthquake essay or earthquake term paper.

Too often have people asked this question and we believe the confusion in this matter is solely due to a lack of knowledge. The scientific community hasn't exactly been sitting idle for the past half century, though despite of all the modern day computing power, it is difficult to predict earthquakes with a hundred percent certainty. Some people have claimed that they've built successful system. People tremble when they hear the word; destruction, mayhem, and tragedy: They occur without warning and cause millions of dollars in destruction and numerous deaths.

For these reasons and more, earthquakes are one of the most unpredictable and devastating occurrences Mother Nature dishes out. Earthquakes usually occur without warning. Disasters come in many shapes, sizes, and forms yet all are detrimental to people and structures of all types. The most terrifying of all disasters are natural disasters, the force of nature is rivaled by no man made disaster.

Essay # 2. Causes of Earthquake: There are many causes for earthquakes. Among them tectonic movement of the earth, volcanic eruption, icefall and landslide are the main ones. Tectonic Movement: The material of the interior of the earth gradually contract due to loss of heat by radiation. Earthquake is one of the natural calamities. Its origin can be traced to the early days of earth formation. It is responsible for a lot of damage to living and non-living beings. For many centuries man didn’t know why earthquakes occur and how they occur and to what extent they would damage.
