Gjermundnes is a hamlet in Norway on the east side of the mouth of Tres Fjord in the municipality of Vestnes.
[3] It is also the location of the Møre og Romsdal Agricultural Museum.
[4][5] Just before 8:00 pm on February 22, 1756, a landslide with a volume of 12,000,000 to 15,000,000 cubic metres (16,000,000 to 20,000,000 cubic yards) — the largest known landslide in Norway in historic time — traveled at high speed from a height of 400 metres (1,312 ft) on the side of the mountain Tjellafjellet into the Langfjorden 40 kilometres (25 mi) from Gjermundnes.
The slide generated three megatsunamis in the immediate area in the Langfjorden and the Eresfjorden with heights of 40 to 50 metres (131 to 164 ft).
Damaging waves, although reduced in size, reached Gjermundnes.
