Tectonically quiet zones seem to have the highest density of known events. Most landslides occur as long run-out distance debris flows, but slumps and deep-seated failures are also relatively common. In abyssal plains the distal product of massive failures is recorded as large megatur-bidites, while on volcanic islands the dominant failure type is flank-collapse with development of debris avalanches. Submarine landslides, excluding megaturbidites, appear to occur in all water depths between the coastline and about 2000 m. Most landslides occupy areas ranging from a few to about 600 km2 and volumes up to 220 km3. Abyssal plain megaturbidites can attain 60,000 km2 and 1,000 km3. The landslides headwall height are clustered around two modes: 0 to 40 m for relatively small landslides and 160 to 200 m for the largest ones. Most recorded submarine landslides are relatively young in age and several events appear to group near the Pleistocene to Holocene transition
