Fig. 1

Location map of the southern Abukuma Mountains, northeast Japan. The inset map shows plate boundaries, directions of absolute plate motion (arrows), and the locations of the main map (rectangle) and the epicenter of the Tohoku-Oki earthquake (star). Plate velocities are from Argus et al. (2011). EU, Eurasia plate; PA, Pacific plate; PH, Philippine Sea plate. The main map shows epicenters and focal mechanisms of events larger than MJMA 4.0 between 11 March 2011 and 28 December 2016 from the F-net catalog of the National Research Institute for Earth Science and Disaster Resilience. Red lines indicate active fault traces (after Imaizumi et al. 2018) and black circles indicate the surface rupture of the 2011 Iwaki earthquake (after Mizoguchi et al. 2012; Toda and Tsutsumi 2013). The base topographic map is originated from GSI
