説明
For mitigating seismic damage of structures during disastrous earthquakes, we have to improve both the procedure for constructing source models for future earthquakes and the method for estimating strong ground motions. The empirical Green's function method (EGFM) is one of the most appropriate methods for estimating strong ground motions near source faults. We constructed the best-fit source models for observed data from the two inland earthquakes, the 2005 West-off Fukuoka earthquake and the 2007 Noto Hanto earthquake using the EGFM. We extended the EGFM to ground motion simulation at soft-layers sites, combining it with the nonlinear analysis in soft soil layers. As a result, the calculated motions on the ground surface underlain by soft layers agree reasonably well with the observed ones. It means that the EGFM is one of the most effective methods for predicting the strong ground motions at both soft-soil sites as well as hard-rock sites.
