There are active faults in the western of Mazandaran Most of them are inverse and right-lateral. The main faults of the area are northwest-southeast general most of these faults are parallel At several points two thousand and three thousand rivers in different lithologies,cuts at high angles or vertical. The training facility is 3 km from the Caspian Sea coast. The geographical structure is 50.86N and 36.79 E, respectivelyExtensive Quaternary sediments of Tonkabon, By geotechnical investigation of a large earthquake zone that a structure can withstand, was calculated. The magnitude of the faults (North Alborz-Javahereh-Banan (Ajr) -Nosha Chalkrud-Kandovan) investigated, By comparing the magnitude of the faults and the size of a structure, Calculates the effect of earthquakes caused by the above faults on regional building and the risk was determined.
