Submarine micro-topography in the western part of Sagami bay.
Hydrographic Department performed the detailed topographic survey with a side-scan sonar and the geological observation of sea bottom with a ROV (Remotely Operated Vehicle) in the western part of Sagami Bay. At the foot of Oiso Spur, there is the seaward extention of Kozu -Matsuda Fault Line. In Sagami Trough, there are many traces of the debris flow or the turbidity current. A large slumpimg has happened and that crown cracks and head scarps was observed off Manazuru Misaki. Age determination by nannoplankton fossils of sedimentary rocks from cliffs continued at the north side slope of Manazuru Knoll indicated 0. 5～1. 3 Ma. At the south side of Manazuru Knoll, there are crown cracks and head scarps of slumps and many traces of the turbidity current. Manazuru Knoll is surrounded by some Faults and has been upheaved as yet.
