Attenuation Relationships for Iran

The purpose of this study is to derive the attenuation relationships for PGA,PGV , and EPA parameters for areas within the seismic zones of Zagros alborz and Central Iran with rock and soit substractures. In order to do so , at first the available scientific data including the methods used for deriving attenuation relationships and the parameters involved have been gatherd. Afterwords, all the efforts have been focused on gathering a thorough catalogue of earthquakes occurred in Iran . in this regard , a majority of the available catalogs in Iran have been gathered and corrected though different methods and finally a set of 89 earthquake events including 307 earthquake records with reliable data was chosen.
