Distribution of frictional parameters used in this study. a Spatial distribution on the plate interface of (A–B) (MPa). Contours: depth (km) to the upper surface of the descending plate (Baba et al. 2006). Gray solid curve: downdip limit of the interplate earthquake distribution (Igarashi et al. 2001). Black crosses: locations used in Fig. 3. Barbed line: trench axis. b Spatial distribution of the characteristic slip distance (L). c–d Profiles of A − B and L along the strike at a depth of 10.15 km.
