Comparisons of the 1D (blue lines) and 3D (red lines) strong-motion Green’s functions with rake angles of 225° for (A) the NS components from a subfault in the deeper part of the Kobe fault, and (B) the EW components from a subfault in the shallow part along the Nojima fault. The filtering and sampling for these Green’s functions are the same as those in Yoshida et al. (1996). The maximum amplitude is given in cm s−1 below each trace. We can see in (A) that the 3D Green’s function at station KOB has a notably larger amplitude than the 1D Green’s function.
