Quick clays involve considerable risks, for example in connection with stability problems, where small initial slips may evolve into large landslides involving the

According to media reports, the affected region is about 200 m (656.2 feet) wide. Quick clay landslides are of two main types – stepwise and uninterrupted. In stepwise landslides, sufficient failed material liquefies that the debris from each step flows away from the slide scarp, leaving an unsupported unstable slope that, in turn, fails and flows away. The Quick clay landslide in Rissa, Sør-Trøndelag in 1978, is the largest in volume that has hit Norway after 1900. Over 20 houses and farms were taken of the Quick-clay landslides are a serious geohazard in Canada, Norway and Sweden. Identification and mapping of quick clays are essential endeavours because the damage caused by an individual landslide can be large and costly, with potentially fatal consequences.

The government agency explained: “There are lengthy and special processes that lead to quick clay landslides that are not necessarily directly related to the current weather. This PhD is expected to improve the current knowledge of quick-clay landslides and how they are preconditioned. Climate change will probably affect the study area in the near future, most likely increasing landslide risk, therefore, research should continue and advance to new levels. 2021-03-25 · The quick clay ground under the affected area of Ask is known to be at high-risk of landslides. Just before Christmas, a smaller landslide occurred a few kilometres further north but neither buildings nor people were affected. Quick clay is generally stable but when the structure is disturbed, the clay can liquify. 2021-01-07 · Quick clay is a kind of clay found in Norway, Sweden, Finland, Russia, Canada and Alaska.

Quick clays are glaciomarine clays The footage confirms that a substantial failure occurred prior to the main Alta quick clay landslide.

The presence of potential quick clays is confirmed using geotechnical investigations, but near-surface geophysical methods, such as seismic and resistivity surveys, can also help identify coarse-grained materials associated with the development of quick clays. Quick clay landslides can occur in flat areas below the marine boundary where quick clay occurs. The landslide can develop quickly where the solid quick clay converts into liquid mass.

Rescuers responded on Thursday, December 30, 2020 to a quick clay landslide in the Village of Ask within Gjerdum municipality in Norway. At least two persons were killed in the landslide. The slide measured 2300 feet by 984 feet (700m by 300m). The collapse injured at least 10 people with one seriously injured.
