000011057 520__ $$2eng$$aWe apply the strong-motion prediction method ‘Recipe’ summarized by the Headquarters for Earthquake Research Promotion of Japan to the simulation of ground motions during the 2005 west off Fukuoka earthquake. We examine four source models. For underground structure, we first construct an initial deep structure model, which is between seismic bedrock and engineering bedrock including some basins, based on borehole and geological data and revise it by using H/V spectra of observed strong-motion records. Although the simulated seismic intensities match to observed ones well, we confirm that it can be improved by introducing an intensity amplification factor. In addition, we found that the rupture velocity is an important source parameter to affect characteristics of calculated long-period waves. We also calculate waveforms on the ground for the center of Fukuoka city in which shallow velocity structure model is constructed. The result implies that we have to do continuous efforts to improve the underground structure models not only deep basin but also surface layers to predict strong-motion accurately much more.
