The Åknes and Hegguraksla mountains in western Norway are beautiful, but the instability of the mountains also poses a huge safety hazard. Once a landslide occurs, it will cause a huge tsunami. People have been worried about this for a long time, until one day it finally happened. The landslide caused a huge tsunami as high as 85 meters, which was about to wipe Norway off the map. A geologist predicted all this and had to start a race against time.
