Field reviews of paleoseismological has been in the archeology trenches of the Gohar tappeh site and geophysical data ( GPR and geoelectric ) from this range is evaluated at the appropriate scale . On the basis of paleoseismology researches , five earthquake events in period of 3639 110 to 4720 132 past years , with magnitude of 7 -6.5 on the moment magnitude scale ( Mw ) detected . The maximum displacement of detected index in paleoseismological observations by the Geophysical perceptions and GPR data also confirmed . Moreover the average course back of earthquake events is estimated at about 330 years . According to Archaeoseismology researches conducted in area , occurrence of earthquake events has been identified that in Range a few hundred years ago Cause loss or migration and immigration of protohistorical Gohar Tappeh people .
