The mechanism and histories of reservoir induced seismicity are studied first to find out the factors affecting reservoir induced seismicity. A questionnaire survey is done to get an opinion of an expert on the effect of all the factors affecting reservoir induced seismicity. The results obtained from this questionnaire survey is used to find out the respective weightages of the factors by analytical hierarchy process. In the second part of the study, seismic details of 20 seismic and aseismic dams are found out in a questionnaire survey format. These details along with the weights found out in the first part of the study is used to find out the equation for reservoir induced seismicity by regression analysis.</span></span></p>
