Abstract

The event of Sarpol-e Zahab with magnitude of 7.3 severely struck the border area of Iran an Iraq in Kermanshah province, leading to catastrophic damages to a wide region, specially Sarpol-e Zahab city. Douts arous whether the damage distribution allover the city stemed from seismic ground response or superficial loose fill material. The issue was explord in this study by especial attention to an area with high damages in Sarpol-e Zahab, called Fooladi. Since the seismic bedrock motion was not available, it was first deconvoluted from the recorded acceleration on the ground surface. Then ground response analysis was conducted at three different locations in Fooladi area, by applying deconvolved motion. It was determined that the local site condotion was accountable for damage severity specially in Fooladi area.
