(a) Map of the seismic survey line used in Ito et al. (2005). Black and gray contours are rupture areas of the 2011 (Lay et al., 2011) and 1978 (Yamanaka and Kikuchi, 2004) earthquakes. (b) Comparison between the hypocenter locations and the 2-D V p model obtained by Ito et al. (2005). The earthquakes before and after the 2011 mainshock are shown by the gray and black dots, respectively. Focal mechanisms of large earthquakes estimated by F-net are shown.
