Figure 1From: Aftershocks of the December 7, 2012 intraplate doublet near the Japan Trench axisMap of the study area. Bathymetric map showing the locations of conventional ocean bottom seismographs (OBS) and ultra-deep ocean bottom seismographs (UDOBS) used in this study and centroid moment tensor solutions of December 7, 2012 intraplate doublet earthquakes by the Global CMT Projects. The iso-depth contour of the 6,000-m water depth is indicated by the thick white line. The total slip distribution of larger than 10 m of the 2011 Tohoku-Oki earthquake from Yagi and Fukahata (2011) is also shown.Back to article page
