Failed submarine landslides on the shelf break, off Fukiage-hama, Satsuma peninsula, Kyushu, Japan

Submarine landslides along the Malacca Strait‐Mergui Basin shelf margin: Insights from sequence‐stratigraphic analysis

[1] The enormously destructive tsunami of December 2004, caused by sudden motion of the Sunda megathrust beneath the Indian Ocean, raised concerns about tectonically induced tsunami worldwide. Submarine landslides may also trigger dangerous tsunami. However, the potential and repeat time for such events is in most places poorly known due to inadequate exploration of the sea floor and age constr...

Relationship between submarine landslides, channel erosion and thrust fault activity in the Nankai Trough, Japan

Following IODP Expedition 333, frontal ramps of submarine landslides were investigated together with a submarine channel-gully system. In this presentation they are shown to reflect thrust-fault activity in the Nankai accretionary wedge, prior to one of the major stages of movement of the large megasplay fault (MSF). Variations in channel bed slope, height and width of channels and gullies indi...

Submarine landslides: processes, triggers and hazard prediction.

Huge landslides, mobilizing hundreds to thousands of km(3) of sediment and rock are ubiquitous in submarine settings ranging from the steepest volcanic island slopes to the gentlest muddy slopes of submarine deltas. Here, we summarize current knowledge of such landslides and the problems of assessing their hazard potential. The major hazards related to submarine landslides include destruction o...

FDM simulation of earthquakes off western Kyushu, Japan, using a land–ocean unified 3D structure model

Seismic activity occurred off western Kyushu, Japan, at the northern end of the Okinawa Trough on May 6, 2016 (14:11 JST), 22 days after the onset of the 2016 Kumamoto earthquake sequence. The area is adjacent to the Beppu–Shimabara graben where the 2016 Kumamoto earthquake sequence occurred. In the area off western Kyushu, a M7.1 earthquake also occurred on November 14, 2015 (5:51 JST), and a ...
