Multibeam bathymetric map around the study area and interpreted map illustrating the formation of the Manazuru Knoll. (Top) Multibeam bathymetric map around the study area. MaK, Manazuru Knoll; KC, Katase Canyon; SK, Sagami Knoll; MC, Miura Canyon; MiK, Miura Knoll. (Bottom) Interpreted map illustrating the formation of the Manazuru Knoll. Black solid lines are the seismic lines of this study. The black area shows the Manazuru Knoll, as estimated by MCS and bathymetric data. Red circles and the red solid line show the anticlinal axis of the Manazuru Knoll obtained by MCS data. The red dotted lines are the anticlinal axis of the Manazuru Knoll estimated by bathymetric data. The yellow lines and yellow arrow show the strike offset of the anticline axis, which is bent. The black broken line indicates the reverse fault. The red arrow represents the crustal movement velocity in Sagami Bay detected by seafloor geodetic observation (Saito et al. 2008).
