Natural disasters in India, many of them related to the climate of India, cause massive losses of Indian life and property. Droughts, flash floods, cyclones, avalanches, landslides brought on by torrential rains, and snowstorms pose the greatest threats. Floods are the most common natural disaster in India.

A shaking of the earth caused by a sudden movement of rock bneath the Earth's surface. An earthquake occurs on a fault, which is a thin layer of crushed rock between two blocks of rock.

Stress builds up and the rocks slip suddenly, releasing energy in waves that travel through the rock to cause the shaking that we feel during an earthquake.
