Submarine landslides are marine landslides that transport sediment across the continental shelf and into the deep ocean. A submarine landslide is initiated when the downwards driving stress (gravity and other factors) exceeds the resisting stress of the seafloor slope material, causing movements along one or more concave to planar rupture surfaces.
A landslide in which the sliding surface is located within the soil mantle or weathered bedrock (typically to a depth from few decimeters to some meters) is called a shallow landslide. Debris slides and debris flows are usually shallow. Shallow landslides can often happen in areas that have slopes with high permeable soils on top of low ...
A Southern California coastal area long prone to landslides continues to inch toward the ocean at a rising speed posing danger to human life and infrastructure, a new NASA report shows.. The Palos ...
It broke from the eastern or windward side of Oʻahu, Hawaiʻi between 1 and 1.5 million years ago and lies in the Pacific Ocean north of Molokaʻi. [1] [2] At the time of collapse, Oʻahu was part of the conglomerate island Maui Nui, elevated above the ocean from lower sea levels, and contained the Koʻolau Volcano. The eastern half of the ...
In traditional usage, the term landslide has at one time or another been used to cover almost all forms of mass movement of rocks and regolith at the Earth's surface. In 1978, in a very highly cited publication, David Varnes noted this imprecise usage and proposed a new, much tighter scheme for the classification of mass movements and ...
The new shoreline is about 250 feet farther out to sea after parts of the seafloor moved an estimated 10 feet vertically, he said, a "manifestation of this bigger, deeper, longer movement of the ...
The townhomes destroyed in the landslide were built in the 1970s, and according to Kyle Tourje, a structural assessor with Alpha Structural, much of the land was graded and reshaped to make room ...
Articles relating to landslides, several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, shallow or deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or ...
