The great 2011 Tohoku-oki earthquake (Mw 9.0) and its 339 foreshocks
and 5,609 aftershocks (9-27 March 2011) were relocated using a three-dimensional
seismic velocity model and local P and S wave arrival times. The
distribution of relocated hypocenters was compared with a tomographic
image of the Northeast Japan forearc. The comparison indicates that
the rupture nucleation of the largest events in the Tohoku-oki sequence,
including the mainshock, was controlled by structural heterogeneities
in the megathrust zone.
