Jan 26, 2015 · This website provides an introduction to understanding landslide risk and guidance on what steps to take if the risk of a landslide is a concern in a particular coastal area. Landslides can occur in high coastal bluffs composed of muddy sediment.

Sep 8, 2017 · Storm-induced erosion of coastal cliffs and hillsides from increased wave activity is an important climactic threat that is often overlooked. Together with excessive precipitation, these erosive processes will be major factors in reshaping the coastline and initiating the next landslide.

The most common landslides along coastal shorelines are shallow failures on steep slopes known as debris avalanches. These often pose the greatest danger to development on the slope or at the bottom of the bluff.

Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows. These are further subdivided by the type of geologic material (bedrock, debris, or earth).

Sep 10, 2018 · Landslides and unstable cliff faces occur throughout the Alaskan coast. They are inherently unpredictable, and major events may occur at any time. Recently released from the grip of glacial ice, this newly exposed landscape is being shaped by water, ice, gravity, as well as biological and tectonic processes.

Apr 23, 2023 · A landslide is a form of mass extinction involving a variety of earth movements such as rockfalls, deep slope failure, and shallow debris. Landslides can occur underwater called underwater landscape, coastal and onshore environment.

Jul 15, 2015 · Coastal Landslide Hazards Maps show locations of known landslides and areas of potential landslide hazard on bluffs along the Maine coast. The explanation describes factors influencing landslide risk.

May 31, 2024 · Information about the USGS Pacific Coastal and Marine Science Center's studies of giant underwater landslides in 1986 and 1988.

Giant landslides in the Canary Islands could potentially generate large tsunami waves at both close and very great distances, and could potentially devastate large areas of coastal land as far away as the eastern seaboard of North America.

Jan 1, 2014 · The complex nature of coastal and submarine mass movements and their consequences calls for a multidisciplinary approach including state of the art coastal, seafloor and sub-seafloor mapping, investigations of physical properties, modeling of landslides and associated tsunamis as well as risk assessment.
