| 抄録（英）： |
We simulated strong ground motions in the source area during the 1995 Hyogoken-Nanbu (Kobe) earthquake based on the source and underground structure models using 3D-FDM. Our modeling is limited from 0.1 to 1.0Hz with lowest S-wave velocity of 0.6km/s for the superficial layer, however, we accomplished qualitative explanations of observed waveforms and the large earthquake disaster distribution in the source area. We can conclude that large strong ground motion distributions are controlled by the heterogeneous rupture process, amplification of deep sedimentary basin and basin-edge diffraction effects, and nonlinear behaviors at the superficial layers along the coastal area. Moreover, we discussed the cause of damage distribution extension into Ashiya and Nishinomiya cities from the points of source and deep sediments.
