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.
Date Place Name/article Position Volume Comments Sources 1.4 Ma off northern Molokai, Hawaii: Wailau Slide 2,500 km 3: The northern third of East Molokai Volcano collapsed suddenly into the Pacific Ocean in a 25-mile (40 km) wide landslide with a 120-mile (193 km) run-out that climbed uphill 900 feet (274 m) from the Hawaiian Trough over the last 80 miles (130 km).
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 ...
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 ...
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 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 ...
The largest known of all prehistoric landslides was an enormous submarine landslide that disintegrated 60,000 years ago and produced the longest flow of sand and mud yet documented on Earth. The massive submarine flow travelled 1,500 km (930 mi) – the distance from London to Rome.
