Source effects on near-source high-frequency strong motion records remain much less known than local site effects. To demonstrate source effects, a strong-motion source inversion analysis is required. However, we have been faced with luck of well-instrumented earthquakes. Exceptionally, the 1987 Whittier Narrows, California, earthquake was excellently instrumented. Application of a source inversion method to this earthquake reveals a complex rupture process. The data records are fit well with the synthetics. The ground motion in the epicentral region predicted on the basis of the inferred distribution of slip is consistent with the real damage and intensity pattern. The ground motion can be well explained by considering source effects. キーワード(英): near-source high-frequency strong motion,source effects,source inversion,fault rupture process 記事区分 - 区分    委員会論文集
