Deterministic Seismic Hazard Analysis of the Region

Abstract

India is considered one of the most seismically active countries. According to severity of earthquake, Indian zones are divided in to five earthquake zones. To carry out seismic hazard analysis for a particular region one should consider the fault earthquake data first. Earthquake catalogue has been generated by considering region covering some area around that particular region. By considering the faults, shear zones, and lineaments in the area having the past earthquake events (more than 150 events), a seismotectonic map can be prepared. Seismic earthquake catalogue has been used to find out the peak ground acceleration (PGA) that will be used to define the maximum credible earthquake. By using simple mathematical equation shortest distance between sites to source has been calculated causing tectonic activity. Peak ground acceleration (PGA) model has been presented for the basic design parameters of that region.
