English Essay on "Natural Disasters on Earthquake"
Earthquake is one of the most terrible natural disasters. Its source 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 did not know why earthquakes come and how they happen and to what area they would damage. He only felt that mother earth was angry with him and so caused the earthquake and he always feared it. A natural disaster is the effect of a natural hazard that leads into environmental, financial and human loss.
There are different types of earthquakes, some are small covering small distances and some are large covering larger distances. Earthquakes are caused by sudden movements of rock beneath the earth. Stresses in the earth cause blocks of rock to break, then move along a fault, or crack. Rocks and earth may slip in any direction along a fault-sideways or up and down. Almost 95 out of 100 earthquakes occur in two great belts - the Pacific Belt, and the Mediterranean Belt. Most of the world's active volcanoes and young mountain ranges are in these areas an erupting volcano sometimes may cause an earthquake. Earthquakes bring widespread distraction.

It is true that a natural disaster is a natural process and we cannot stop it with the limited knowledge of nature. But by making certain preparations, we can reduce the magnitude of the loss to life and property. First of all we should reduce global warming which is the root cause of all the problems. We should also have insurance policies so that we could have sufficient money to rebuild our lives after any such disaster. The scientists should invent advance warning systems. While construction we should make sure that it is strong enough to withstand earthquakes. We should educate people about evacuation during any disaster.
