Relation between characteristic time and moment magnitude of the afterslip following the foreshock of March 9. The hatched area represents the scaling law for various slow earthquakes proposed by Ide et al. (2007). Solid circles represent the cases for the 1989/1992 Sanriku-oki earthquakes (Kawasaki et al., 2001). The solid rectangle denotes the case of the afterslip following the Mw 7.3 foreshock as revealed in this study.
