Abstract
The present paper was done under the title of peak
ground acceleration(PGA) on bedrock and uniform seismic
hazard spectra(UHS) for different regions of Golpayegan city. A
set of seismic sources, historical and instrumental seismicity data
within the radius of 200 kilometers from the city center since the
year 1316 until now has been collected and used. Kijko[2000]
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. The calculations were performed by using the logic tree
method, Five weighted attenuation relationships were used;
including Ghodrati et al (2007), 0.3; Ambraseys et al (1996), 0.2 ;
Campbell-Bozorgnia (2000), 0.15 ; Campbell-Bozorgnia (2009),
0.15 and Akkar & Bommer(2010), 0.2. 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, Ambraseys et al
(1996), 0.3 ; Ghodrati et al (2010), 0.3 ; Campbell (1997), 0.2 &
Berge-Thierry (2003), 0.2 were used. The SEISRISKIII (1987)
software was used to calculate the earthquake hazard. The results
of this analysis were submitted including the spectra and maps for
10% and 2% probability of event in 50 years.
