Marine clay deposits in coastal, post-submarine areas of Scandinavia and North America may be subjected to quick clay landslides and hence significant efforts are being taken to map their Quick clay is a special type of glaciomarine clay that poses a significant land slide hazard in the northern hemisphere’s high latitudes. Norway, Sweden, Finland, Russia, and Canada are prone to quick clay occurrences. In Canada, quick clay is often referred to as Leda or Champlain Sea clay. Data insufficient to indicate the clay content or the swelling potential of soils. The map above is based upon "Swelling Clays Map of the Conterminous United States" by W. Olive, A. Chleborad, C.

Hybrid Ceramic Synthetic Clay. In de Hybrid Ceramic Synthetic Clay Kit zit een speciale synthetische klei-applicator pad die hergebruikt kan worden. Quick clay is known to be a hazard in formally-glaciated coastal areas in, e.g., Norway, Sweden and Canada.

11 Oct 2019 Quick-clay landslides are common geohazards in Nordic countries and Canada. The presence of potential quick clays is confirmed using

Introduction. Quick clay refers to a specific type of clayey material that experiences a significant loss of strength when it is disturbed. Quick clays are glaciomarine formations that can be found mostly in the Northern Hemisphere in several regions, such as parts of Norway, Canada, Russia and the United States. Quick clay slide in Rissa 29th April 1978 was the largest quick clay slide that hit Norway in he 20th Century. 5–6 million m3 clay slid out from an area of 330 dekar and left a slide scar of 1,5 kilometers. Over 20 dwellings and farms were taken by the slide, and one person was killed. Quick clay is a clayey material with unique behavior since it experiences a significant loss of strength when it is disturbed.

Similar unstable clay soils or quick clay found in Rissa, Norway, led to an April 1978 soil collapse covering more than 330,000 squre meters. Map of quick clay

. Digitally Kitsumkalum–Kitimat trough was relatively rapid, although there were several The resultant quick clay lost nearly. Quick clay has a major impact on landslide risk and it is therefore of considerable interest to map its presence and extent. In Sweden, quick clay has been Since it is an area with highly sensitive clays, mapping of quick clay areas and estimation of possible landslide extent were important parts of the investigation.
