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.
A type of seismic zone is a Wadati–Benioff zone which corresponds with the down-going slab in a subduction zone. [2] The world's greatest seismic belt, known as the Circum-Pacific seismic belt, [3] is where a majority of the Earth's quakes occur. Approximately 81% of major earthquakes occur along this belt.
A seismic hazard is the probability that an earthquake will occur in a given geographic area, within a given window of time, and with ground motion intensity exceeding a given threshold. [ 1 ] [ 2 ] With a hazard thus estimated, risk can be assessed and included in such areas as building codes for standard buildings, designing larger buildings ...

It came on the heels of two other earthquakes on June 7 in the same area near the city of Buford — a 2.5 magnitude quake and another of 2.1 magnitude, which shook the area a few hours earlier ...
The 1948 seismic codes were prepared in consideration of the seismic zone map. A new code was revised in 1961 and in 1963, the seismic zonation map was updated with four hazard levels based on predicted shaking on the Modified Mercalli intensity scale. It was subsequently added a fifth hazard level in the 1972 revision. [12]
