Abstract

Arias intensity is considered a shaking parameter suitable for characterizing earthquake impact on ground stability. Within the framework of a study aimed at providing tools for the assessment of hazards related with earthquake induced slope failures, Arias intensity attenuation relations were determined for the Zagros Mountains region, an active tectonic belt elongated NW-SE in the western and south-western part of Iran. The calculation of relation coefficients was based on strong-motion data of earthquakes located in the Zagros area and recorded by Iranian stations managed by BHRC (Building and Housing Research Center of Iran). Five models of attenuation relation were considered and their coefficients were estimated through a least square regression analysis. The relations obtained were then applied to a data sample different from that used for regression and the RMS (Root Mean Square) of residuals was examined in order to compare effectiveness of different relations in probabilistic estimates. Furthermore a comparison made with attenuation relations obtained *Manuscript Click here to view linked References 2 for the Alborz and central part of Iran showed significant differences possibly related to structural differences.
