However, experts say the Gjerdrum area has suffered quick clay landslides before, but not on this scale. The quick clay ground under the affected area of Ask is known to be at high-risk of landslides. 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. 2020-12-31 · Quick Clay Landslide in Norway Injures One — GeoPrac.net Posted on 31 December 2020 by Don Warrington A landslide struck the village of Gjerdrum, which is about 25km (15 miles) north-east of the Norwegian capital, Oslo.

Alta: a truly remarkable video of a quick clay landslide in Norway One of the top ten landslide videos of all time was captured yesterday at Kråknes in Alta, in the north of Norway.

The collapse of the quick clay Quick clay slides in Norway Quick clay slides are typical in Norway and Sweden. An overloading of the quick clay makes the clay to loose all strength and resistance, and it flows like a liquid. Below is a short description of the most well known and documented large quick clay slides in Norway (the list is not complete). Quick clay, also known as Leda clay and Champlain Sea clay in Canada, is any of several distinctively sensitive glaciomarine clays found in Canada, Norway, Russia, Sweden, Finland, the United States and other locations around the world. Quick clay (and other types of sensitive clay) is formed in Norway in areas where clay was deposited in a saline marine environment, and subsequently lifted near or above sea level due to post-glacial uplift. Groundwater flow has gradually washed out the electrically charged particles from the sediment pore water. Quick clays are glaciomarine deposits that are mostly found in the Northern Hemisphere including many parts of Norway.

The first quick-clay hazard mapping started in the beginning of 1980, in the southeast and middle parts of Norway, initiated by the big quick-clay landslide in Rissa, Norway, in 1978. Today, there are nearly 2000 mapped quick-clay hazard zones in Norway, and the mapping is still ongoing. Gregersen O (1981) The quick clay landslide in Rissa, Norway.
