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 ...
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.
Instability in the edifice of El Golfo volcano resulted in El Hierro's youngest and largest landslide, the El Golfo lateral collapse landslide, when a large part (with a volume of 180 km 3 (43 cu mi)) of the volcano's northern flank slid downwards off the island and onto the ocean floor; individual blocks of moved material, up to 1,200 m (3,900 ...
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 ...
Large landslides from volcanoes often bury valleys with tens to hundreds of metres of rock debris, forming a chaotic landscape marked by dozens of small hills and closed depressions. If the landslide deposit is thick enough, it may dam streams to form lakes. These lakes may eventually drain catastrophically to create floods and lahars ...
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 ...
Giant landslides and collapses of ocean island volcanoes were first described in 1964 in Hawaii and are now known to happen in almost every ocean basin. [1] As volcanoes grow in size they eventually become unstable and collapse, generating landslides [2] and collapses such as the failure of Mount St. Helens in 1980 [3] and many others. [4]
