Earth Quake

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 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 more slowly bellow the surface under the range of millimeters to kilometers. the rate of movement increases with the hickness of plates. such huge moving plates get separated from other plates get separated from other plates and get out of their boundarles. earthquake occurs when such moving plates clash with each other and separate.

Sometime 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 surrouding areas. thus, volcanic activity within the earth surface is one of the reasons for earth quakes. faults created by volcanic activity are filled up by the strong earth 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 windows, building 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 sick
- If some one is in the running car, he/she must stop the car and stay inside until the earthquake stops
