New strong motion attenuation relations are presented for NE Italy. These relations are calibrated on a huge data set of strong- and weak-motion recordings. The comparison of the behaviour of this new regional relation for PGA and some others, suitable for the study region, points out its fast attenuation in the far field. Considering some hazard results obtained with different attenuation relations, both in terms of hazard maps and hazard curves for specific sites, the new regional relation drives us to higher PGA values, mainly due to its high standard deviation, and, consequently points out the importance of a robust attenuation model in seismic hazard assessment.

Abstract

New strong motion attenuation relations are presented for NE Italy. These relations are calibrated on a huge data set of strong- and weak-motion recordings. The comparison of the behaviour of this new regional relation for PGA and some others, suitable for the study region, points out its fast attenuation in the far field. Considering some hazard results obtained with different attenuation relations, both in terms of hazard maps and hazard curves for specific sites, the new regional relation drives us to higher PGA values, mainly due to its high standard deviation, and, consequently points out the importance of a robust attenuation model in seismic hazard assessment.
