Rhine cutting through Flims Rockslide debris, Switzerland. Storegga Slide, some 8,000 years ago off the western coast of Norway. Caused massive tsunamis in Doggerland and other areas connected to the North Sea. A total volume of 3,500 km 3 (840 cu mi) debris was involved; comparable to a 34 m (112 ft) thick area the size of Iceland ...
Translational slides often are rapid movements along a plane of distinct weakness between the overlying slide material and the more stable underlying material. Slides can be further subdivided into rock slides, debris slides, or earth slides depending on the type of the material involved (see table). Type of Movement.
A debris flow is a moving mass of loose material that travels down a steep slope under gravity. It can be very fast, long, and dangerous. Learn how to identify, trigger, and prevent debris flows from various sources such as rainfall, eruptions, or logging. See videos, maps, and photos of actual events and examples.
17. Apr. 2020 · Debris slides are composed primarily of coarse materials including natural soils, unconsolidated sedimentary materials, and rock detritus. Increased pore (water) pressure or velocity can transition the sliding into the flowing mode of debris avalanches (Varnes, 1978).

30. Nov. 2013 · A suitable composite name for such an event would be “irregular rock slide-debris slide”. The limited velocity of the debris slide stage indicates an absence of liquefaction, although the talus was clearly mobilized by an increase in pore pressure, due to undrained loading.

Debris flow: A debris flow is a form of rapid mass movement in which a combination of loose soil, rock, organic matter, air, and water mobilize as a slurry that flows downslope (fig. 3F). Debris flows include <50% fines. Debris flows are commonly caused by intense surface-water flow, due to heavy precipitation or rapid snowmelt, that erodes and ...
21. Juli 2020 · Photos of the Slumgullion debris slide, USA (panel d), and the La Clapière rock slide, France (panel e), provide examples of slow-moving landslides.
