Description
Effects of reservoir filling are studied well during past decades by increasing monitoring stations around dams. In this study, a period of more than 10 years of seismicity around Seymareh dam (a major dam Southwestern Iran) is monitored and thousands of minor earthquakes around the lake is processed and evaluated before and after reservoir filling. Various parameters of active locations and faults, depth of events, magnitude, seismicity parameters (a-value, b-value) and source migration is explored in detail. It has been shown how lots of very shallow events are imposed on the area and how it affects by water level variations. An optimum rate for water level change is detected to minimize the induced seismicity effectively.

Far from dam's body, structures and living areas around dams are vulnerable when induced earthquakes happen
