In order to investigate the characteristics of the incident seismic wave, the seismic array observation simultaneously at 4 sites (HMY, SZJ, CHS and TTY) in Kanto District were constituted. We have tried to investigate the characteristics of the seismic waves theoretically based on the observed seismic wave records (61 earthquakes, 1269 components recorded from June 1979 to December 1981) at 4 sites using the simple fault model and the underground conditions in the Kanto District. From this investigation, the remarkable difference concerned with the characteristics of incident seismic waves in the Kanto District were recognized more clearly. These results reported in this paper would be a first step for the estimation of incident seismic wave characteristics in the Kanto district.
