a Locations of the 141 GEONET stations (solid triangles) used in this study, relative to the 2011 Tohoku megathrust earthquake and subducting plate interface. The study is focused in northeastern Japan, where the Pacific Plate subducts beneath the Okhotsk Plate at the Japan Trench. The beach-ball symbol indicates the centroid moment tensor solution of the 2011 Tohoku megathrust earthquake obtained by JMA (Japan Meteorological Agency), and the squares delineate the inferred fault ruptures from a coseismic fault model (Nishimura et al. 2011). The solid lines represent the plate boundaries (Bird 2003). The dashed lines represent the plate interface contours (Hayes et al. 2012) at 20 km intervals. b Example of the time-series data at the Kuji GEONET station, numbered 0027 on the map. The white lines represent the smoothed results. Both the 30-s sampling high-rate data (upper figure) and daily data (lower figure) following the mainshock are presented
