The three Storegga Slides count among the largest recorded landslides. They occurred under water on the edge of Norway's continental shelf (Storegga is Norwegian for "the Great Edge") in the Norwegian Sea, 100 km north west of the Møre coast, where an area the size of Iceland slid, causing a megatsunami in the North Atlantic Ocean. The latest incident occurred around 6100 BC. In Scotland, traces of this tsunami have been recorded.
As part of the activities preparing the Ormen Lange natural gas field, the incident has been thoroughly investigated. One conclusion was that the slide was caused by material built up during the previous ice age, and that a reoccurrence would only be possible after a new ice age.
