Guest editorial for the special issue “Tectonics of Bay of Bengal and Arabian Sea with special emphasis on coastal and marine geohazards”

Estimation of design basis earthquake using region-specific Mmax, for the NPP site at Kalpakkam, Tamil Nadu, India

“…The evolution of the Indian Ocean, the present morphology and tectonics of the bordering continental margins are the consequences of the breakup of Eastern Gondwana land and subsequent seafloor spreading between the constituent continents viz., Madagascar, Seychelles, India, Antarctica, and Australia, since the Early Cretaceous (Murthy et al, 2011). The recent occurrence of earthquakes in coastal regions of the East as well as West Coasts of India has invoked interest among the earth scientists to study the coastal seismicity in relation to morphological and tectonic lineaments associated with coastal and near-shore regions of the continental shelf (Murthy et al, 2010).…”

“…The recent occurrence of earthquakes in coastal regions of the East as well as West Coasts of India has invoked interest among the earth scientists to study the coastal seismicity in relation to morphological and tectonic lineaments associated with coastal and near-shore regions of the continental shelf (Murthy et al, 2010). Much work needs to be done in understanding the tectonics of the Bay of Bengal and the Arabian Sea to address coastal and marine geohazards of the region (Murthy et al, 2011). Here, it can be noted that macro scale geological studies are carried out for land part and limited studies are found for ocean part.…”

“…Indian Ocean is the third largest ocean of the world and is comprised of diverse and complex tectonic features (Murthy et al, 2011). Studies available for the Eastern Continental Margin of India (ECMI) are briefly presented here.…”
