<Ul> <Li> Storegga Slide, some 8,000 years ago off the western coast of Norway . Caused massive tsunamis in Doggerland and other countries connected to the North Sea . A total volume of 3,500 km (840 cu mi) debris was involved; comparable to a 34 m (112 ft) thick area the size of Iceland . The landslide is thought to be among the largest in history . </Li> <Li> Landslide which moved Heart Mountain to its current location, the largest continental landslide discovered so far . In the 48 million years since the slide occurred, erosion has removed most of the portion of the slide . </Li> <Li> Flims Rockslide, ca . 12 km (2.9 cu mi), Switzerland, some 10000 years ago in post-glacial Pleistocene / Holocene, the largest so far described in the alps and on dry land that can be easily identified in a modestly eroded state . </Li> <Li> The landslide around 200 BC which formed Lake Waikaremoana on the North Island of New Zealand, where a large block of the Ngamoko Range slid and dammed a gorge of Waikaretaheke River, forming a natural reservoir up to 256 metres (840 ft) deep . </Li> <Li> Cheekye Fan, British Columbia, Canada, ca . 25 km (9.7 sq mi), Late Pleistocene in age . </Li> <Li> The Manang - Braga rock avalanche / debris flow may have formed Marsyangdi Valley in the Annapurna Region, Nepal, during an interstadial period belonging to the last glacial period . Over 15 km of material are estimated to have been moved in the single event, making it one of the largest continental landslides . </Li> <Li> A massive slope failure 60 km north of Kathmandu, involving an estimated 10--15 km .
