Probabilistic seismic hazard assessment for offshore structures in Andaman Sea

Abstract
A set of probabilistic seismic hazard maps for Offshore structures in Andaman sea has
been derived using procedures developed for the latest US National Seismic Hazard Maps. In contrast
to earlier hazard maps for this region, which are mostly computed using delineated seismic source zone,
the presented maps are based on the combination of smoothed gridded seismicity, crustal-fault, and subduction source models. The ground motion hazard map is presented over a 10 km grid in terms of peak
ground acceleration and spectral acceleration at 1.0 undamped natural periods and a 5% critical damping
ratio for 10 and 2% probabilities of exceedance in 50 years, which have generally been used for Seismic
Analysis and Design of Offshore Structures.
