The Geological Survey of India (G.S.I) first published the seismic zoning map of India in the year 1935. This map tells us about the earthquake-prone areas in India. The Map is colour coded in a different colour which shows four different seismic zones of India.
They are as follows:
1. Zone – II: This is the least active seismic zone.
2. Zone – III: It is included in the moderate seismic zone.
3. Zone – IV: This is considered to be high seismic zone.
4. Zone – V: It is the highest seismic zone.
