Map showing the locations of the rupture starting points of SMGAs (open stars). The large and small solid stars indicate the epicenters of the mainshock and reference event (EGF1) both determined by JMA, respectively. Solid triangles indicate the strong motion stations used for locating SMGAs. The broken contour lines represent the depth of the plate interface by Nakajima and Hasegawa (2006) and Nakajima et al. (2009) with an interval of 10 km.
