In other words, the earthquake zoning map of India divides India into 4 seismic zones (Zone 2, 3, 4 and 5) unlike its previous version, which consisted of five or six zones for the country. According to the present zoning map, Zone 5 expects the highest level of seismicity whereas Zone 2 is associated with the lowest level of seismicity.
The usage of these maps in India, Pakistan and China are governed by different laws that restrict depictions of boundaries other than what is officially recognized by the state. Please check local laws and modify the map accordingly before use.

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.
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.
An orogenic belt, orogen, or mobile belt, [a] is a zone of Earth's crust affected by orogeny. [2] An orogenic belt develops when a continental plate crumples and is uplifted to form one or more mountain ranges ; this involves a series of geological processes collectively called orogenesis .
The National Centre for Seismology (NCS) is an office of India's Ministry of Earth Sciences. [1] The office monitors earthquakes and conducts seismological research. Specifically, it provides earthquake surveillance and hazard reports to governmental agencies. It consists of various divisions: Earthquake Monitoring & Services
The epilogue of the tectonic evolution was marked by granitic and rhyolitic magmatic events, namely the emplacement of the Erinpura granite and the Malani Volcanics on the western side of Aravalli-Delhi orogenic belt. [4] This event is ranked third among the largest igneous province in the globe, with a total area of about 52,000 km 2 in India. [9]
