SEISMIC HAZARD ESTIMATION FOR RANI AVANTI BAI SAGAR PROJECT AT BARGI

Rani Avanti Bai Sagar Project at Bargi is a multipurpose project in the state of Madhya Pradesh (India). In this study seismic hazard has been estimated for Bargi Dam site. The probabilistic Seismic Hazard analysis has been used. Effects of all the faults, which can produce earthquake equal to or more than 3.5 Magnitude and those within a radius of 300 Km from the centre of the Masonry Dam has been considered. The past history of earthquakes indicated that a total 82 earthquakes, of magnitude 3.5 or more has been occurred in last 175 years. The maximum magnitude reported within the region of consideration is 6.5 in 1927 at Umaria. Probabilistic approach use these data for hazard Analysis. Results are presented in the form of peak ground acceleration and seismic hazard curves.
