We propose a synthetic procedure for predicting strong ground motion at a specific site from a future large earthquake using a semi-empirical method. First, we estimate regional scaling relations of source parameters based on observed ground motion data from earthquakes occurring in the objective region. Next we select appropriate empirical Green's functions, I.e., observed records from small events, judging from the event locations and source characteristics. The parameters required for synthesizing strong ground motion are estimated from the empirical scaling relations. Furthermore, empirical Green's functions are corrected by considering the differences in stress drop, attenuation effect due to propagation media, high-frequency cutoff (F■) of acceleration spectra, and radiation patterns between large and small earthquakes. In this paper, the above procedure is applied to ground motion prediction for future earthquake (M=7, ■=13km) caused by the NEGORO fault in Wakayama, Japan. We obtained the results whein the peak acceleration and velocity of the synthetic motion are comparable to the empirical values estimated from Watabe's and Kanai's formulas, respectively, and the upper limits of the synthetic velocity response spectra show good agreement with the design response spectra by Ohsaki. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
