Calamities that occur due to nature are called natural calamities or disaster’s .Such as earthquake, floods, cyclones, drought, famine etc. Earthquake is defined as the shaking of earth .Factors which are responsible for causing earthquake are plate tectonics, malformation of rocks, crystallization of sedimentary rocks and due to volcanoes. During earthquake seismic waves come out from the earth’s surface. It causes high rate of destruction. At the same time it may be helpful to the scientist to know more about the earth. Animals have the super senses to detect these seismic waves and they migrate into safety places. When an earthquake occurs many people get injured and many people loose their lives and become homeless .Affected people receive food, medicine from others .We can protect ourselves from the earthquake by leaving the house immediately and going to an open ground. If you can’t move lay down under strong thing like a table and hold it tightly. .On 26th Jan 2001, people of India experienced an earthquake of very high intensity.
