... Abstract Submarine landslides can pose a significant threat to offshore installations and coastal communities. They can strike installations far from their origin and generate destructive tsunamis. To assess and quantify this hazard, it is necessary to be able to model their dynamics in complex...

... an alternative view, where an initial small failure can grow into a larger failure at the point of initiation. A result is that an explanation of the conditions leading to failure can be attributed to many submarine landslides. Further, accounting for the potential propagation of a shear band in the future...

... Abstract Sørfjord outside the village of Finneidfjord has a history of landsliding throughout the Holocene. The 1996 landslide -the focus of this study - has many characteristics typical of submarine landslides (well-developed slip plane, outrunner blocks, peripheral thrusting and lateral...

..., situated in the French part of the Ligurian Margin, represents a landslide-prone area, where different factors favour slope instability: (i) Seismicity up to ~M6, (ii) rapid sediment deposition in the Var fluvial system, (iii) groundwater discharge along the coastal aquifer, (iv) creeping of sensitive clay...

... Abstract According to statistics for the Mississippi Rived Delta (MRD), landslides accounted for a significant amount of damage to off-shore pipe. This study focuses on the pipeline response to offshore landslides for various orientations of the pipeline with respect to the direction...
