Abstract :
This study has carried out seismic hazard analysis and Peak Ground Acceleration (PGA) in different regions of Arak City located in Markazi province of Iran. I-listorical and instrumental earthquakes data sets from 4 B.C. to 2007 were used, and seismic sources up to 200km-radius surrounding Arak City were considered in modeling. In addition, seismicity parameters were calculated by kijko (2000), and three Attenuation relationships were used with Logic Tree method. Analysis was conducted for 17 x 12 grid points over Arak region and provance area with SEISRISK III (1987) software. Results were shown by PGA maps for four hazard levels.
