Today we have been to the cinema to see a Norwegian catastrophe movie; Bølgen (The Wave). What happens in the movie could happen in real life.
From IMDB:
Even though awaited, no-one is really ready when the mountain pass of Åkneset above the scenic narrow Norrwegian fjord Geiranger falls out and creates a 85 meter high violent tsunami. A geologist is one of those caught in the middle of it.
