The vertical seismic array records at the Kobe Port Island during the1995 Hyogoken-Nambu earthquake are simulated. One-dimensional ground models and a two-dimensional ground model are numerically analyzed by effective stress method. The 2-D model consists of the unimproved area including seismic array site and adjacent improved area by compaction method. The 1-D models represent those two areas respectively. Compared the 2-D model with the 1-D models, the improved ground affects the earthquake responses of the seismic array point. Moreover, the vertical settlement of the ground surface using the results of the 2-D analysis corresponds to the observational settlement.
