State of the art review of seismic hazard approaches in Indian context

Abstract

Numerous researchers have carried out seismic microzonation of India using various criteria. Seismic zonation was conducted at the national and regional levels using the conventional approaches i.e., either a probabilistic or a deterministic approach. Between the computed peak ground acceleration and the real peak ground acceleration observed during the seismic event, significant differences have been detected. Different approaches (conventional and new) have been used in the literature to conduct seismic hazard analysis and site-specific analysis of India in order to address this issue. The goal of the current work is to evaluate critically various researchers’ approaches to seismic hazard analysis and compare those to Indian codal provisions already in place with a highlight of need for further research and modifications.
