Storegga ([[Norwegian language|Norwegian]]: ''Great Edge'') is located at the edge of Norway's continental shelf in the Norwegian Sea, {{convert|100|km|mi|abbr=on}} north-west of the [[Møre og Romsdal|Møre]] coast. In around 6200 BCE, structural failures of the shelf caused three underwater [[landslide]]s, which triggered very large [[tsunami]]s in the North Atlantic Ocean. The collapses involved an estimated {{convert|290|km|mi|abbr=on}} length of coastal shelf, with a total volume of {{convert|3500|km3|cumi|abbr=on}} of debris.<ref name=stein>{{cite journal | first1 = S. | last1 = Bondevik | first2 = J. | last2 =Mangerud | first3 = S. | last3 = Dawson | first4 = A. | last4 = Dawson | first5 = Ø. | last5 = Lohne |date=5 August 2003 | title = Record-breaking Height for 8000-Year-Old Tsunami in the North Atlantic | journal = Eos, Transactions, American Geophysical Union | volume = 84 | issue = 31 | pages = 289, 293| doi=10.1029/2003EO310001 | bibcode=2003EOSTr..84..289B | hdl = 1956/729 | doi-access = free | hdl-access = free }}</ref>
