Fig. 1

Epicenters of earthquakes from 1920 to 2020 with M ≥ 5.0 and shallower than 100 km by JMA catalog. Stars and circles are M ≥ 6.9 and 6.9 > M ≥ 5.0 earthquakes, respectively. Blue stars show earthquakes for which fault models are estimated from seismic analyses and offshore active faults. Red stars show earthquakes for which fault models of previous studies and offshore active faults are used. Green box in the inset map shows the area of Hokkaido and Tohoku
