Found this article and a very good map here . I am reproducing it. Read it and Think. I found it very relevent in the wake of recent happenings in Japan.
FoThe massive earthquake in Japan and the subsequent nuclear crisis has triggered fears of nuclear security across the world, including India.
Most of India falls in the moderate risk to very high risk seismic zones and so do a majority of India’s nuclear reactors. While there are no nuclear projects in Zone V (seismic intensity of 8 and above), the proposed Jaitapur Nuclear Power plant falls in Zone IV on the earthquake hazard zoning map. The map plots India’s nuclear power plants on a seismic map.
