Abstract: 

In this paper, the characteristics of reservoir-induced earthquakes of five large Dams of Iran that located in the different seismotectonic region are investigated.
For this, the earthquakes occurred in the radius of 30 Km of dam site have been analyzed. The investigation showed that the epicenter of earthquakes generally located in the side of reservoir .the frequency of earthquakes are related to the type of Dams and tectonic area and the rate of induced earthquake are as same as the tectonic earthquakes. The frequencies of low magnitude in case of karoun 3 after Dam canstruction are increased but the frequencies of high magnitude are decreased. In the case of Latian and Lar dams the frequency of earthquakes are decreased.
