Fig. 3.

Spatial distribution of CMTs of (a) interplate aftershocks, (b) non-interplate aftershocks in the hanging wall, and (c) non-interplate aftershocks in the foot wall. Symbols are the same as in Figs. 2(a) and (b). The black and pink contours respectively denote coseismic and postseismic slip estimated from GPS data observed in a period from March 11 9:00 to May 11 18:00, 2011 (Geospatial Information Authority of Japan, 2011). The contour intervals for coseismic and postseismic slip were 8.0 and 0.4 m, respectively.
