The Indian subcontinent has a history of devastating earthquakes. [1] The major reason for the high frequency and intensity of the earthquakes is that the Indian plate is driving into Asia at a rate of approximately 47 mm/year. [2] Geographical statistics of India show that almost 58% of the land is vulnerable to earthquakes.
Earthquake epicenters 1963–98. In seismology, a seismic zone or seismic belt is an area of seismicity potentially sharing a common cause. It can be referred to as an earthquake belt as well. It may also be a region on a map for which a common areal rate of seismicity is assumed for the purpose of calculating probabilistic ground motions.
The reason for the intensity and high frequency of earthquakes is the Indian plate driving into Asia at a rate of approximately 47 mm/year. [1] The following is a list of major earthquakes which have occurred in India , including those with epicentres outside India that caused significant damage or casualties in the country.
Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake.They are distinguished from seismic magnitude scales, which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking.
The Seismology Division and Earthquake Risk Evaluation Centre of the India Meteorological Department merged with NCS in August 2014 to more effectively monitor and research seismological activity. The Centre's objective is to improve understanding of earthquake processes and their effects through seismological research and monitoring.
Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design, earthquake engineering or structural assessment and retrofit (see structural engineering) in regions where earthquakes are prevalent.

Countries affected by the 2004 Indian Ocean earthquake. According to official estimates in India, 10,749 people were killed, 5,640 people were missing and thousands of people became homeless when a tsunami triggered by the 2004 Indian Ocean earthquake near the Indonesian island of Sumatra struck the southern coast on 26 December 2004.
