Abstract

The relationship between the soil amplification ratio and the ground condition was examined using strong motion records measured at 77 JMA stations in the period of over 8 years. The amplification ratio for the instrumental JMA intensity as well as the peak ground acceleration and velocity was obtained from the station coefficients of the attenuation relationships. The combined use of the geomorphological land classification and the surface geology was found to give the best estimate of the amplification ratio. This result suggests that the Digital National Land Information may be conveniently used for the estimation of strong motion distribution of a large area in Japan.
