The map showing the studied area. The large and small solid stars represent epicenters of the 2011 Tohoku earthquake (Mw 9.0) and two EGF events by JMA, respectively. Solid triangles indicate the strong motion stations whose observed ground motions are plotted in the record section in Fig. 2. The broken rectangle indicates the source fault plane of the 2011 Tohoku earthquake (from Suzuki et al., 2011).
