Description:
Failure of submarine slopes results in underwater landslides, a mass movement of sediment and rock that spills down ocean margin slopes (Hampton and Locat, 1996). Visual observations during submarine mass movement are few, and therefore landslides are commonly recognized by the remnant morphology they leave behind. These remnant slope failure features have been observed along the world’s continental margins, on the slopes of volcanic islands, and volcanic island arcs. Initiation of landslides commonly results from dynamic events, generally earthquakes. Landslides are most frequent along margins where converging lithospheric plates form subduction zones and the shear between the upper and lower plates create large earthquakes, however, some large landslides occur without tectonic or seismic triggers. Sedimentary processes have caused failure from loading or unloading. Submarine landslides in the spectrum from fast to slow can be catastrophic, incremental, or creeping. Large ca ...
