In this study an updated deterministic seismic hazard contour map of Bhubaneswar (20°12'0"N to 20°23'0"N latitude and 85°44'0"E to 85° 54'0"E longitude) one of the major city of India with tourist importance, has been prepared in the form of spectral acceleration values. For assessing the seismic hazard, the study area has been divided into small grids of size 30?×30? (approximately 1.0 km×1.0 km), and the hazard parameters in terms of spectral acceleration at bedrock level, PGA are calculated as the center of each of these grid cells by considering the regional Seismo-tectonic activity within 400 km radius around the city center. The maximum credible earthquake in terms of moment magnitude of 7.2 has been used for calculation of hazard parameter, results in PGA value of 0.017g towards the northeast side of the city and the corresponding maximum spectral acceleration as 0.0501g for a predominant period of 0.05s at bedrock level.
