GEOLOGY

Detailed explanation-1: -Landslides can also happen on the ocean floor and can be triggered by nearby earthquakes or other events. Usually the only man-made structures that can be damaged by the mass of seafloor are underwater cables. Unlike a slide on land, however, an underwater landslide can also cause a strong water wave called a tsunami.

Detailed explanation-2: -Steep slopes and areas at the bottom of slopes or canyons; Slopes that have been altered for construction of buildings and roads; Channels along a stream or river; and. Areas where surface runoff is directed.

Detailed explanation-3: -Landslides are more widespread than any other geological event, and can occur anywhere in the world. They occur when large masses of soil, rocks or debris move down a slope due to a natural phenomenon or human activity. Mudslides or debris flows are also a common type of fast-moving landslide.

Detailed explanation-4: -Photo by Ted S. Warren/Concord Monitor. Experts said that the primary reason for the Oso mudslide was rain. Water can trigger landslides and mudslides because it alters the pressure within the slope, which leads to slope instability.

Detailed explanation-5: -Submarine landslides are a broad term for indicating the phenomena of failure of near-seabed sediments under the effect of gravity. From: Regional Geology and Tectonics (Second Edition), 2020.
