Geirangerfjord (UNESCO 2005)
Nicknamed the « Pearl of the Fjords », this 15 km long sea inlet cuts into the Sunnmøre mountains in Møre og Romsdal county. UNESCO-listed in 2005 (with Nærøyfjord) as one of the world's most spectacular and preserved fjords. Iconic waterfalls: the Seven Sisters (De Syv Søstrene, 7 parallel falls side by side over 250 m), the Bridal Veil (Brudesløret), the Suitor (Friaren) facing them. Geiranger village (200 year-round inhabitants, ~700,000 visitors/year), reachable by ferry from Hellesylt (1h, Fjord1 line) or by road via the Trollstigen / Eagle Road and its 11 vertiginous switchbacks. Dalsnibba viewpoint at 1,500 m (toll road, summer only).
The Geirangerfjord is THREATENED by the potential collapse of the Åkerneset mountain flank (on neighbouring Storfjord): since 1986, Norwegian geologists have been monitoring a 800-million-m³ rock fracture sliding ~10 cm per year. The day this flank falls into the sea (estimate: within decades), it will trigger a 70-to-85-metre tsunami that will wipe out the villages of Geiranger, Hellesylt and Stranda in 10 minutes. Norway installed an early-warning system (sirens + GPS sensors + seismometers) in 2008, and Geiranger's population is trained to evacuate to higher ground within 10 minutes. Despite this known risk, residents refuse to leave.
