Dam construction site as one of geological seismocity zone of Zagros is highly potential of earthquake. Most of huge earthquakes in this zone happen up to 1500 m of heights. Historical important earthquakes have happened in 840 in Ahwaz and in 1052 in Bagh Malek which were 6.8 Richter and the earthquake of Zagros which was 6.5 Richter. Important faults near the construction area are Pir Ahamd fault and... Certainly faults of Golestan, Togah, Lali and Masjed Soleiman are some of faults in 60 km distance range of the site, which can have seismocity potential.
The maximum acceleration of geo-structure for different levels is as follows:
