Earthquake disaster study as well as mitigation is important for the safe and economic design of structures. Ankleshwar is the major industrial hub of India, situated in Bharuch district, located at south-west coast of Gujarat and lies in seismic zone III as per Indian seismic zonation. In present study, the seismic risk analysis of Ankleshwar city is carried out considering the past earthquake records. Earthquake catalogue consisting of all earthquake events from 1819 to 2019 is prepared within 400 km radius of the Bharuch district. After identifying the seismic sources and declustering of earthquake catalogue, the shortest distances from each seismic source responsible for the tectonic activity have been calculated. For the Ankleshwar city, the peak ground acceleration values at rock level have been determined using predictive relationships. The analysis reported that the PGA values are ranging from 0.18 to 0.38 g with respect to maximum credible earthquake of magnitude (Mw) 5.8 generated from Son Narmada Fault. The basic design parameters arrived from the PGA model can be used for the seismic design of structures in the Ankleshwar city.
