Attenuation relationships are proposed for PGA, PGV, spectrum intensity (SI), instrumental seismic intensity, and acceleration response spectrum of ground motion at the Class I, II, and III ground and engineering bedrock using about 11,000 strong motion records observed in Japan. The attenuation relationships include short period level of acceleration source spectrum as one of variables besides moment magnitude and source distance. After taking the short period level of each earthquake into consideration, errors of the regression analyses become remarkably smaller than those without short period level. Dependence on magnitude and regional difference of short period level are also discussed.
