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

In this paper, the peak ground acceleration (pga) over the bedrock is calculated by a probabilisticand deterministic seismic hazard assessment. an active fault map of the region is prepared. for this purpose,all active faults in a radius of 100 km from amol city center are recognized and their seismic and raptureparameters are determined. afterwards, for seismic hazard analysis, the seismic parameters of study region aredetermined and seismic classification zone is performed. maximum earthquake, seismic parameters and alsooccurrence rate are determined. seismic hazard analysis is performed using 3 different attenuation relationshipsresulted in seismic hazard curves for amol city center. the peak ground acceleration (pga) for design levelsmce, obe and benefit life structure 50 and 100 years are presented. for the pga quantity design levelsoperating base earthquake (obe), maximum credible earthquake (mce) for horizontal and vertical dimensionswere equal to sequences of 0.33, 0.5 and 0.3, 0.53 g, respectively.
