Earthquake:-
An Earthquake is basically the vibration of Earth produced by the rapid release of energy. This energy radiates in all directions from the source, focus, in the form of waves. The intensity of an earthquake and the destruction it causes are greater over softer soil regions, for example on alluvial soils, than on more rocky areas. The magnitude or intensity of energy released by an earthquake is measured by the Richter scale. It ranges from between 0 and 9. India is divided into five earthquake Zones (Seismic Zones) based on the intensities of earthquakes recorded on the Modified Mercalli Scale.

The Indian subcontinent has a history of earthquakes. The reason for the intensity and high frequency of earthquakes is that the Indian plate driving into Asia at a rate of approximately 49 mm/year.
