Abstract


In this study, synthetic catalogs based on the Monte Carlo simulations have been produced for probabilistic seismic hazard assessment (PSHA), in the Kermanshah region, West of Iran. Resultant seismic hazard zoning maps, hazard curves and three-dimensional deaggregation of seismic hazard are provided. In order to validate the estimated peak ground accelerations (PGAs), the deduced uniform hazard response spectra (UHRS) are compared with the recorded PGAs in some stations near to the large Mw 7.3 earthquake occurred in the western part of Iran near to Iraq border on 12 November 2017. Different ground motion prediction equations are tested and the results are compared.
