Probabilistic Seismic Hazard Assessment For Ground Motion Studies At VNSGU Western India

Abstract

The occurrence of earthquake is natural. Most of the regions in the world are leads to earthquake prone. The regions that are frequently exposed to large earthquakes are seismically active regions of the world. The Western Indian shield considered as a stable continental region, has become an area of low - moderate to high seismicity. During the last 50 years, more numbers of earthquakes of moderate magnitude have occurred in this region, 3 to 4 high risk earthquakes are occurred with higher magnitude. Recent earthquakes in the coastal regions of Gujarat have invoked interest to study the coastal seismicity in relation to morphological and tectonic lineament. the result of the seismic hazard computation is then used to construct uniform hazard curve for the two earthquake return periods. The PGA value obtained from PSHA approach for Veer Narmad South Gujarat University, Gujarat region is 0.081g and 0.105g for 475 and 2475 years return period.
