Abstract

Seismic vulnerability analysis, an approach to get an estimate of the strong ground-motions at any particular site, is mainly intended for earthquake resistant designs or for seismic safety assessments. The hazard analysis usually attempts to analyze two different kinds of anticipated ground motions, “The Probablistic Seismic Hazard Analysis” (PSHA) and “The Detemininstic Seismic Hazard Analysis” (DSHA). A sincere effort is made herein to do seismic hazard analysis for Sondur Dam site of Chhattisgarh state . The study consists of broadly two parts, the first part basically gives a detail overview of the seismicity of the region and identification of various faults existing within the Dam site with all their details and the second part includes DSHA analysis for the same. An attempt was made to compile the occurrence of past and recent seismic activities within 300 km radius, around the Sondur Dam site. Further the seismic hazard analysis was carried out at substratum level in terms of PGA using (DSHA), deterministic seismic hazard analysis technique. The main benchmark and indicator involved in carrying out the hazard analysis is the correctness and completeness of the data which needs to be attained. Finally the results are furnished in the form of peak ground acceleration(PGA) which can be used directly by engineers as fundamental considerations, for generating earthquake-resistant design of structures in and around Sondur Dam site.
