Abstract
AbstractThe importance of characterizing site-specific free-field surface motion of facilities of national and worldwide economic influence [like ports and nuclear power plants (NPPs)] is well-realized, especially in Mumbai, the most important commercial city in India, with 40% of its land reclaimed from the Arabian Sea. In the research reported in this paper, site-specific seismic hazard and one-dimensional (1D) equivalent linear ground response analysis (GRA) of important sites in Mumbai [Jawaharlal Nehru Port (JNPT), Mumbai Port, Bhabha Atomic Research Center (BARC), and Tarapur Atomic Power Station (TAPS)] are attempted. The seismicity of the research region is modeled through delineation of 31 fault sources with an earthquake database of the past 418 years (years 1594–2012). The epistemic uncertainty in hazard estimation is accounted by employing seven different ground motion prediction equations developed for worldwide shallow crustal intraplate environments. The probabilistic seismic hazard analysi...
