Research Abstract

For Empirical prediction of strong-ground motion, the attenuation relationship of peak ground velocity is proposed from Japanese strong-motion records. Firstly the strong-motion records observed in Japan are collected and compiled. Using the dataset, the peak amplitudes as well as event and station data are compiled.
The functional form of the attenuation relationship is set considering source spectral characteristics, saturation of ground motion intensity in source area, and site effect. The parameters in the relationship are moment magnitude, source distance, and average shear wave velocity of ground. Using about 100 strongmotion records from seven Japanese earthquakes with M of 6.5 to 7.8, the attenuation relationship is developed by the statistical analysis.
The relationship proposed is compared with observations during the 1995 Hyougo-ken-nanbu earthquake and other destructive earthquakes. The relationship shows good agreements with the observation, indicating that the relationship proposed would be applicable at close distances.
