Probabilistic and Deterministic Seismic Hazard Assessment in Amol Center, a City in North of Iran

In this paper, the peak ground acceleration over the bedrock (PGA) is calculated by a probabilistic and deterministic seismic hazard assessment. The active fault map of the region is prepared. For this purpose, all active faults in a radius of 100 km of Amol City center are recognized and their seismic and rapture parameters are determined. Afterwards, for seismic hazard analysis, the seismic parameters of study region are determined and seismic zones classification is preformed. Maximum earthquake, seismic parameters, and occurrence rate are determined. seismic hazard analysis are performed using 3 different attenuation relationship, resulted in seismic hazard curves for Amol City center, and peak ground acceleration (PGA) for design levels MCE, OBE and benefit life structure 50 and 100 years are presented. For the PGA quantities design levels OBE, MCE for horizontal and vertical dimensions were equal to sequences of 0.33, 0.5 and 0.3, 0.53 g, respectively.
