Comparison between hypocenters by the OBS networks (red circles) and those determined by the JMA (blue circles). The inverted green triangles indicate positions of the pop-up type OBSs and the land-based seismic station. Grey circles indicate hypocenters of aftershocks determined by the JMA from March 12th to 19th. Note that a low seismicity area is seen 50 km south of the OBS network.
