At the Earth’s surface‚ earthquakes manifest themselves by vibration‚ shaking and sometimes displacement of the ground.

The phenomena of Natural Disasters An earthquake is sudden motion or trembling of the ground produced by the abrupt displacement of rock masses. HOW DO THEY OCCUR? The earth’s outer shell is divided into seven major and some smaller plates which are constantly in a dynamic state‚ pushing against‚ pulling away from‚ or grinding past one another. Forces build up as the plates attempt to move in relation to each other. When the adhesions along the fault give way‚ stored energy is released in the

When summer is quite severe sometimes what was once a large reservoir of water shrinks to a pool. Both human beings and animals suffer for want of water. If it rains it rains and rains and there is a flood. The cultivated crops under deep water rot and perish. When there is inadequate yield of crops there is famine. Rice and wheat scarce and there
