As for the 9,900-MW Jaitapur Nuclear Power Project in the eco-sensitive Konkan region of Maharashtra, Dr Kakodkar said the site is less vulnerable to tsunamis and earthquakes as it is located on a plateau and falls in Seismic Zone 3, which is geologically less active..
(Zone 3 is classified as Moderate Damage Risk Zone on a scale of 2 to 5, with Zone 2 associated with the lowest level of seismicity.)
The locational advantage that the 29-metre-high Jaitapur plateau has over a site at sea-level needs to be understood in the context of the 10-metre tsunami that hit Sendai and other regions on the east coast of Japan on Friday. The tsunami led to flooding and explosion at the Fukushima 1 nuclear plant on the east coast.
According to an eminent earth scientist from IIT, a tsunami is highly unlikely on the west coast of India. Such geologically active zones are found near Japan and Java.
