Relocated hypocenters by the MJHD method in this study. Epicentral distribution and a vertical cross section along the A–B line, which is perpendicular to the strike of the nodal plane of the global CMT solution (Dziewonski et al. (1981) and later updates), are shown. This nodal plane corresponds with the fault plane. A C–D line is perpendicular to the strike of the other nodal plane of the global CMT solution. (a) The mainshock (2011/03/11 5:46) and immediate aftershocks within 24 hours. (b) The largest foreshock (2011/03/09 2:45) and its aftershocks. MS indicate the mainshock. (c) The largest Mw 7.9 aftershock off Ibaraki (2011/03/11 6:15) and aftershocks within 24 hours after the mainshock. (d) The Mw 7.6 aftershock at the outer rise (2011/03/11 6:25) and aftershocks.
