Fig. 4.

Source model consisting of five SMGAs. The five SMGAs are superposed on the distribution of peak moment-rate inverted using strong motions data by Yoshida et al. (2011). The initiation point at each SMGA is roughly estimated by the back-propagation method. The area, stress drop and initiation point of each SMGA are estimated from the forward modeling, comparing the observed and synthetics ones using the empirical Green’s function method. The open star and closed stars show the epicenters of the mainshock and small events A, B, and C, respectively. The small rectangles and closed circles inside them show the SMGAs and their initiation points. The closed red triangles indicate the KiK-net stations used for analysis.
