Comparison of hypocenters determined by the OBS networks (red circles) and those determined by the JMA (blue circles). The inverted green triangles indicate the positions of the pop-up-type OBSs used for the locations. Grey circles indicate the hypocenters of aftershocks determined by the JMA from March 15th to June 18th. Note that the aftershock distribution obtained by this study is not uniform in time and space; however, positions of the re-located aftershocks have a spatially high resolution.
