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 ...
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).
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 ...
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 ...
A number of homes in northern Norway collapsed into the sea on Wednesday due to a powerful landslide. Around 4 p.m. local time, authorities first received reports of the incident in Alta, a town ...
The Alta landslide occurred on 3 June 2020 in Alta Municipality in Finnmark county, Norway near Kråkneset, a small village about 6 kilometres (3.7 mi) southeast of the larger village of Talvik, Altafjorden. The landslide developed on a marine clay substrate that had originally formed in the early Holocene epoch when the area was under sea level.
