Caption

Fig. 1. (A) Distribution of 382 seismic stations used in this study. Red and pink beach balls denote focal mechanisms of the 2011 Tohoku-oki earthquake (Mw 9.0) and other megathrust earthquakes (Mw ? 7.0) during 1917 - 2017, respectively. The white line marks the downdip limit of interplate seismicity. Yellow dashed lines denote depth contours of the upper boundary of the subducting Pacific plate. (B) Tectonic settings of the study region (blue box). Black saw-tooth lines: oceanic trenches.
