Probabilistic Seismic Hazard Assessment Studies on the Central-East of Iran-Kerman Region

Seismic hazard analysis of the earthquake-prone eastern of Iran-Kerman regions-has become more important due to its growing economic importance. Many cities in that region have experienced life and financial losses due to major earthquakes in recent years. Therefore, in this study, the goal was to estimate the seismic hazard curves and site-specific spectrums with probabilistic approaches for the Kerman region. The main faults in the region were identified, earthquake catalogues, declustered catalogues and seismic parameters were obtained. The earthquake parameters were calculated for active faults using the earthquake ground motion levels with several ground motion predicting (attenuation) models. The spectral acceleration coefficients were calculated and site-specific acceleration spectrum were depicted and compared. The findings showed that the peak ground acceleration values varied between 0.13 and 0.33 g for earthquakes, with a 10% probability of exceedance in 50-year period and 0.27-0.53 g for a probability of 2%. Seismic hazard curves were developed, this curve would help engineers in design of earthquake resistant structures for the region.
