From: Seismicity near the hypocenter of the 2011 off the Pacific coast of Tohoku earthquake deduced by using ocean bottom seismographic data

Fig. 7.

Space-time distribution projected using two orthogonal axes shown in Fig. 6. The stars show the LFS (Largest ForeShock) and MS (MainShock). (a) Space-time plot between -30 and 0 days before the MS of the seismicity along the dip of the subducting plate boundary (X-axis). (b) Space-time plot between −30 and 0 days before the MS of the seismicity along the strike of the subducting plate boundary (Y-axis). (c) Space-time plot of the seismicity along the X-axis from the LFS to the MS. (d) Space-time plot of the seismicity along the Y-axis from the LFS to the MS.
