Hypocenters of mainshock and aftershocks in a 24-hour period for the 2011 Tohoku earthquake (black circles) and aftershock areas for M ≥ 7 earthquakes since 1926 (green lines, Uchida et al., 2009). Hypocenter data are from the Japan Meteorological Agency. Red dashed line shows down-dip limit of the Philippine Sea Plate (Uchida et al., 2009). Thick pink line shows the western limit of interplate earthquake distribution from Igarashi et al. (2001) and Uchida et al. (2009).
