Earthquake is a natural calamity can occur anytime and anywhere on the earth surface, cause lots of disturbance of to the living beings and useful natural resources. If we think about the earthquake, we also think that nothing is more destructive than this natural calamity. Earthquake has its long devastating history from the ancient time all over the world however its monotonous regularity makes us more fearful. Earth crust consists of several unfixed solid rock faces which move slowly below the surface under the range of millimeters to kilometers. The rate of movement increases with the thickness of plates. Such huge moving plates get separated from other plates and get out of their boundaries. Earthquake occurs when such moving plates clash with each other and separate.
Sometimes volcanos (located around edges of the Pacific Ocean, known as Ring of Fire) bursts and releases lots of lava, gas, etc which causes pressure and imbalance within the earth surface and produces earthquake waves in the surrounding areas. Thus, volcanic activity within the earth surface is one of the reasons for earthquakes. Faults created by the volcanic activitiy are filled up by the strong earht surface movement which causes tremor. Everyone should take care of them when earthquake occurs by following some precautions like:
People should stay calm and stay inside or outside the door but away from windows, buildings and power lines.They should stand against the wall near to the center of building, at doorway and crawl under some heavy furnitures like a desk or table.Never use flammable things like matches, candles, or any other flame as they caught fire with broken gas lines.Never use elevators as they may stuck.If someone is in the running car, he/she must stop the car and stay inside until the earthquake stops. Long Essay on Earthquake Earthquake Essay 4 (400 words)Earthquake is a natural calamity which has power to destroy human lives in few seconds. It is lonely responsible for the huge damage to living and non-living beings. Earlier, people were unaware of the reasons of earthquake occurrence and the extent of damage. 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.
