摘要：In this study, a set of seismic sources as well as historical and instrumental seismic data since 8th century up to the present time with a radius of 150 kilometers were utilized. Considering lack of suitable seismic data and uncertainty of magnitude in different periods, Kijko program (2000) was used to estimate seismic parameters. The calculations were performed using the logic tree method. Five weighted attenuation relationship were used, namely Ramazi (1999), Ambraseys et al (1996), Campbell (1997) , Zare et al (1999) and Ghodrati et al (2007) which were combined with weights of 0.2, 0.15, 0.15, 0.2 and 0.3, respectively. In order to determine the acceleration spectra from weighted attenuation spectral relations, Ambraseys et al. (1996) and Ghodrati et al (2010) were utilized in the logic tree method with weights of 0.4 and 0.6, respectively. SEISRISK III software was used for calculating the earthquake hazard. The results of this analysis are presented in the iso-acceleratin maps, spectral acceleration maps and uniform hazard spectrum maps for 2 and 10 probability percent in 50 years.
