Location map of developed anchored-buoy OBSs with land seismic stations close to the OBSs. Bathymetric contours in the marine area where the water depth is shallower than 200 m indicate intervals of water depths of 10 m. Red circles indicate the position of the recovered anchored-buoy OBSs. The gray circle indicates the position of the OBS that could not be recovered. Inverted triangles and squares denote the position of permanent land seismic stations and temporary stations, respectively. Small gray circles denote the epicenter of aftershocks determined by the JMA from June 18 to July 13, 2019. A few OBSs and temporary land seismic stations on the coast are effective for the location of hypocenters
