Geologists assess that an eventual catastrophic collapse of of rock into [[Sunnylvsfjorden]] is inevitable and could generate megatsunamis of in height on the [[fjord]]′s opposite shore. The waves are expected to strike [[Hellesylt]] with a height of , [[Geiranger]] with a height of , [[Tafjord]] with a height of , and many other communities in Norway′s [[Sunnmøre]] district with a height of several metres, and to be noticeable even at [[Ålesund]].
