Abstract

The present paper revels a deterministic seismic hazard analysis for the central headquarters of Chhattisgarh. Central part of Chhattisgarh comes under Peninsular India which is tectonically identified as an intraplate region of Indian plate. Due to the convergent movement of Indian plate with Eurasian plate, movements are occurring along major intraplate faults resulting the seismic activity of the region and so its hazard assessment is very important. For deterministic hazard analysis, – linear seismic sources within a radius of 300 km were considered and the peak ground acceleration (PGA) at rock level was evaluated for the district headquarters Bilaspur, Janjgir, Raigarh and Korba of Chhattisgarh . The attenuation relations proposed by Iyengar and Raghukanth (2004), was used in the analysis. The effects of variation of focal depth over maximum PGA (g) values at rock level were reported for central district headquarters Bilaspur, Janjgir, Raigarh and Korba.
