Comparison with plate interface coupling models. (a) High-frequency relative energy release (background colour within rupture areas) compared with slip-deficiency model based upon GPS data by Hashimoto et al. (2009) (blue contours). The red star with black outline indicates the epicentre as determined by the back-projection technique, and red dots show the locations of the aftershocks between March 11 and 17 (JMA catalogue). (b) Same as in (a) except that the blue contours show coupling strengths inferred by Loveless and Meade (2010). (c) Same as in (a) except that the comparison is made to source regions of historical tsunamigenic earthquakes provided by Hatori (1987).
