Abstract

Summary

It is discussed acoustic characteristics on the submarine landslide and gravity flowing and their impact on the west slope of the Okinawa Trough.

Morphometric statistics give useful insight into submarine landslides. Four types of occurrence were recognized in seismic reflection patterns. Submarine landslide distribute mainly in a belt along the through near the fault zone on the upper slope. Gravity flowing deposits distribute mainly from the lower of the fault zone to the Okinawa Trough bottom.

The gradient of slope and sediment supply indicates that submarine landslide and gravity flowing deposits are extensive on the west slope.

Submarine landslide often appears the top of slope and downward the slope is the sediments creeping or debris flowing deposits. Lentoid turbidities bodies are often on the foot area of the slope, and turbidity plain appears on the bottom of the trough. The structure of the slope was the result of serial erosion-deposition.
