Abstract
Strong ground motion of the 1948 Fukui earthquake was studied. Using discontinuous FDM grids and dynamic model, the effect of 3-D structure and dynamic source process was considered. The fault was assumed to be strike slip with relatively simple rupture process on a vertical plane. The velocity motions calculated by considering the two processes, i. e. the fault rupture process and the amplification process by sediment, were compatible with the observed directions of fall and collapse. However, the results disagreed slightly in the northern part. The simulation in the northern part might be improved by incorporating the role of dip angle and dip slip of the fault into the analysis.
