Attenuation Relationships for Shallow Crustal Earthquakes Based on California Strong Motion Data

Abstract

Attenuation relationships are presented for peak acceleration and response spectral accelerations from shallow crustal earthquakes. The relationships are based on strong motion data primarily from California earthquakes. Relationships are presented for strike-slip and reverse-faulting earthquakes, rock and deep firm soil deposits, earthquakes of moment magnitude M 4 to 8+, and distances up to 100 km.
