Abstract

In this paper, the seismicity models in Karkheh and Karoun III dam sites before and after impounding are investigated. The results show that location of earthquake epicenters, focal depths and the other seismic parameters around the reservoirs, after filling of reservoir of dams were changed. Also, a good matching has seen between water level and earthquake frequency in both dams. The only difference between the induced seismicity of two dams is the longer delay time of earthquakes response to rising of water level in Karoun III relative to Karkheh; because the permeability of bedrock around the Karoun III is higher than the Karkheh.
