A probabilistic Seismic Hazard Analysis (PSHA) was performed on the basis of Cornell-McGuire method (Cornell 1968; McGuire 1977) and the uniform hazard spectra corresponding to the probability of exceedence 10% and 2% , (PE=10% and PE=2%), of the Bazargan telecommunication building site were estimated.
In this paper the well known computer program SEISRISK III (Bender and Perkins 1987) which is a computer program for seismic hazard estimation was used for hazard analysis procedure. A collection of available cataloged consist the recorded and historical events was used for calculating the parameter b value for the selected region based on Gutenberg-Richter relation. The maximum magnitude value was determined using the well known Kijko approach. The aftershocks were removed using windowing procedure proposed by Gardner and Knopoff. Using the response spectral-based attenuation relationships the peak ground accelerations (PGA) and the elastic response spectra with 5% damping ratio corresponding to the probability of exceedenses 2% and 10% were estimated.
