Abstract

In this paper, SEISMIC ZONATION of PEAK GROUND ACCELERATION (PGA) in the DAMAGED AREAS of 2005 February 22 Dahooiyeh-Zarand earthquake is presented. The PGA is evaluated in the DAMAGED AREAS with both interpolation technique and ATTENUATION RELATIONSHIPS. In the interpolation method, PGA is estimated in different regions using inverse distance weighting (IDW) method and recorded PGA at the stations located in meizoseismal area of Dahooiyeh-Zarand (2005) earthquake. The optimum power of IDW method for best estimation of PGA is decided from the root mean squared error statistic. Then, IDW is applied to estimate PGA in the DAMAGED AREAS where no records of PGA were available. In the second step, The PGA is estimated in the DAMAGED AREAS using ATTENUATION RELATIONSHIPS of both Campbell and Bozorgnia (2008) and Fukushima (2003) ATTENUATION RELATIONSHIPS. Furthermore, the ATTENUATION RELATIONSHIPS were corrected by minimizing the difference between estimated and recorded PGA at the recording stations, where the PGA of mainshock was available. The results revealed that the estimated PGAs from the Fukushima (2003) attenuation relationship provides more accurate results than those derived from the other methods.
