Cooperative Research for Strong Ground Motion Prediction

点击翻译按钮获取中文摘要

The purposes of this cooperative research project are (1) to compare and evaluate usual prediction methods of strong ground motions for future large earthquakes in the points of Applied seismology and Engineering Seismology and (2) to find and establish more accurate estimation method of strong ground motions. Our study period was from 1993 to 1995. During this period, we had a variety of earthquake disasters by the 1993 Kushiro-Oki, Hokkaido-Nansei-Oki, the 1994 Hokkaido-Toho-Oki, Sanriku-Haruka-Oki, and the 1995 Hyogoken-nanbu earthquakes. Members of this research group carried the cooperative strong motion observations and/or analyzes. Especially, our group members tried to investigate the cause of the Great Hanshin-Awaji earthquake disaster by empirical, semi-empirical, and theoretical approaches and elucidated quantitatively. On Jan., 1996, the symposium on prediction of strong ground motions was held with not only our group members but foreign researchers. Moreover, we made a report on Cooperative Research for Strong Ground Motion Prediction.
