However, variation of the characteristics of ground motion with an azimuth angle has not been sufficiently researched based on observation records of strong motion. In this paper, we focused on the variation of the characteristics of long-period ground motion observed in the Kanto Basin, Japan, due to the path and subsurface of the sedimentary basin. We evaluated the response spectrum and group delay time of the records using indices of ground motion characteristics. The response spectrum and the group delay time were calculated for several earthquake groups that were divided based on hypocenter locations and azimuth angle from the station. The relation between the groups, the variation of response spectrum, and group delay time were quantitatively analyzed and discussed. Consequently, it was found that the response spectrum and group delay time of the ground motion have different characteristics in each grouped area. In particular, the shapes of the response spectra for the long-period ranging from 2 s to 10 s varied depending on the area`s direction.
