Geophysical characterization of areas prone to quick-clay landslides
These landslides are retrogressive, meaning they usually start at water, and progress upwards at slow walking speed, although particularly deep quick clay layers on sloped regions may collapse much more rapidly, or in very large chunks that can slide at great speed due to the liquid nature of the disturbed clay. They have been known to An impressive quick clay landslide occurred in St-Luc-de-Vincennes, Quebec, Canada on November 10, 2016. Several homes were evacuated, although, luckily, no injuries were reported. A massive portion of land fell into a stream that flows into the St. Lawrence River. According to media reports, the affected region is about 200 m (656.2 feet) wide.

We study the rheology of quick clay, an unstable soil responsible for many landslides. We show that above a critical stress the material starts flowing abruptly with a very large viscosity decrease Se hela listan på en.wikipedia.org Quick clays are glaciomarine deposits that are mostly found in the Northern Hemisphere including many parts of Norway. Quick clay landslides have caused severe impacts on human civilization mostly due to their large size and the absence of an alert mechanism.

Quick clay slides can propagate very quickly backwards (retrogressively) over large areas, and the slide debris will float over considerable distances. The quick clay slide in Rissa (north of Trondheim in central part of Norway), in April 1978 was filmed while in action. Quick clay landslides therefore develop very quickly and often over large areas, even in quite flat terrain. It develops retrogressively, which means it starts at the bottom and goes backwards in the terrain as the quick clay is overloaded when the clay below has collapsed.
