Archaeoseismological investigation along the Khazar fault system, based on the Paleoseismology (Gohar Tappeh protohistory Site, Behshahr- Mazandaran)

Archaeologists believe that men who lived in Archaeological sites of Mazandaran such as Komishan cave, Hutu and Kamarband, After leaving the cave were gradually formed the Gohar tappeh. Over time, people living with the loss of previous places were higher places. In Neolithic village has been form of rural life there, and And the Bronze period considered and the state of urbanization has found. Archaeological studies dating this area back to seven thousand years and findings of the Bronze era (the third millennium), Iron II Age (mid-second millennium B.C.) unfold it. this study provided Archaeoseismology based on knowledge paleoseismological on the fault system of the Khazar in the protohistory area on Gohar tappeh in Behshahr of Mazandaran province. 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 3500 to 5000 past years, with magnitude of 7 -6.2 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 375 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.
