Uniform Seismic Hazard Spectra for Different Regions of Rasht, Iran

This research titled Uniform Seismic Hazard Spectra for Different Regions of Rasht, Iran was conducted to estimate seismic parameters for Rasht city in Iran. . A set of seismic sources, historical and instrumental seismicity data within the radius of 222 kilometers from the city center since the year 859until now was collected and used. Kijko[2221] method was applied for estimating the seismic parameters considering lack of suitable seismic data, inaccuracy of the available information and uncertainty of magnitude in different periods. The calculations were performed by using the logic tree method. Furthermore, in order to determine the seismic spectra based on weighted attenuation spectral relationships, and also for the reason of being spectral and more suitable with the conditions of the zone, Ghodrati et al (2212), 2.3 ; Campbell-Bozorgnia(2229), 2.3& Zare (1888), 2.4 were used. The SEISRISKIII (1891) software was used to calculate the earthquake hazard. The results of this analysis were submitted including the spectra and maps for 121 and 21 probability of event in 52 years
