Seismic Hazard Analysis and Uniform Hazard Spectra for Different Regions of Kerman

Abstract

This paper was present a seismic hazard analysis and uniform hazard spectra for different regions of Kerman city. A collected catalogue containing both historical and instrumental events and covering the period from 8th century AD until now within the area of 200 Km in radius were used and Seismic sources are modeled. Kijko method has been applied for estimating the seismic parameters considering lack of suitable seismic data, inaccuracy of the available information and uncertainty of magnitude in different periods. To determine the peak ground acceleration the calculations were performed by using the logic tree method. Two weighted attenuation relations were used; including Ghodrati et al, 0.6 and Zare et al, 0.4. Analysis was conducted for 13×8 grid points over Kerman region and adjacent areas with SEISRISK III software and in order to determine the seismic spectra Ghodrati et al, spectral attenuation relationships was used.
