Studies on reservoir induced seismicity at various dam sites have been undertaken since last fifty years or so. The objectives of the studies are mainly to monitor the pre- and post-impoundment levels of seismicity and to assess the realistic seismic risk. Results of these studies could be more fruitfully utilized for two diverse purposes, viz., application to earthquake control and economic design of dams and appertenant structures. For this purpose it is necessary to widen the scope of the studies to include geological and geophysical aspects, rock properties and local hydrology.
