Empirical Arias Intensity attenuation relationships for the seismic hazard analysis of Greece

New empirical attenuation relationships of Arias Intensity for various site conditions, based on the strong-motion data recorded in Greece are presented. With regard to attenuation relationships, for the region of Greece, there are no Arias Intensity empirical attenuation models available today that may be used in seismic hazard analysis. For each site class, the attenuation relationship of Arias Intensity is expressed as a function of moment magnitude (M) and epicentral distance (R) and it is derived using a mixed effects regression analysis method. As a final result probabilistic seismic hazard maps in terms of Arias Intensity have been developed for the territory of Greece.
