| 抄録（英）： |
A hybrid technique has been developed to simulate ground motion excited by external sources in 3D local geological structure models. We use the hybrid approach combining the discrete-wavenumber (DW) 3D finite-difference methods. This technique is convenient in increasing the quality of sedimentary structure model of basin through the parametric simulations of ground motion records, because our technique needs less computer memory and time. The accuracy of the technique has been tested through numerical comparison with the results obtained using DW method. As a practical application, we have simulated the ground motions in the northern area of Osaka basin for the MJMA 5.1 earthquake occurred in southern Kyoto.
