The location map with seismic lines. (a) Regional scale bathymetry map of the Japan Trench region, off Miyagi, northeastern Japan. Red rectangle in the inset map corresponds to the area shown in Figure 1a. Yellow star denotes the epicenter of the Tohoku earthquake that occurred on 11 March 2011. Yellow lines indicate the seismic survey lines used in this study. Yellow numbers are the CDP numbers. Red inverted triangle is the location of the JFAST drill site C0019. (b) Close-up map around drill site C0019 with bathymetry contours. Green inverted triangle indicates the site location of OBS JF1. Blue lines show the seismic survey lines and blue numbers are the CDP numbers.
