0.8429. The maximum value of peak ground acceleration (PGA) for a recurrence period of 100 years for the headquarter of Ambikapur was found to be due to fault F7 having a fault length of 46 km with a hypo-central distance of 14.366 km, and was 0.09587 g for 50 percentile and 0.15259 g for 84 percentile. On the other hand, the maximum value of peak ground acceleration (PGA), for the recurrence period of 100 years for the headquarter Baikunthpur [Koria], which was found to be due to fault F8, having fault length of 140 km, hypo-central distance of 17.598 km, and was estimated to be equal to 0.14554 g for 50 percentile and 0.23165 g for 84 percentile. For Korba and Jashpurnagar, the peak ground acceleration (PGA) for a recurrence period of 100 years found to be for fault F6, fault length of 46 km, and F9, fault length of 30 km are respectively very low. Using PSHA approach, a seismic hazard curves have been prepared for the major district headquarters of north Chhattisgarh. For Baikunthpur [Koria], the estimated return was found to be a period of 3848 year for 0.1g. The outcome of the present study is directly used for the design of earthquake resistance structures.
