From: Slip distribution of the 2011 off the Pacific coast of Tohoku Earthquake inferred from geodetic data
Estimated coseismic (left) and postseismic (right) slip distribution. Colors and white arrows denote the absolute amount and direction of the fault slip, respectively. Red ellipses in the left panel are the estimated source regions of past earthquakes (The Headquarters for Earthquake Research Promotion, 1999). Red star and black dots are the hypocenter of the main shock and aftershocks determined by JMA. The contour lines in the right panel show the coseismic slip distribution, and the black broken line shows the northeastern end of the Philippine Sea plate. Red stars are aftershock epicenters lager than M 5.5 from 14:55 to 23:00 on 11 March.
