Probabilistic seismic hazard approach for low seismic regions, Visakhapatnam, Andhra Pradesh, IndiaDIA

Abstract

This paper presents seismic hazard analysis of Visakhapatnam using probabilistic approach. Visakhapatnam is a rapid growing coastal city in India and considered as stable region with low intensities. In this paper previous earthquake history of region was considered to generate earthquake recurrence relation. The mean annual rate of exceedence is generated against peak ground acceleration considering study area site conditions. From the present investigation the values of peak ground acceleration varies from 0.004 g to 0.02 g with rate of exceedance 50% and 0.05 g to 0.12g for 10% rate of exceedance.
