Mannen

Mannen (lit. "The Man") is a mountain in Rauma Municipality in Møre og Romsdal county, Norway. The tall mountain is located just west of Horgheim, along the river Rauma in the Romsdalen valley. Mannen has a distinctive needle peak. The mountain's shape has been compared to an enormous seated goose that looks out over the Rauma valley, from which it can easily be seen.
Overview.
A major landslide of up to of material is said to be impending on the unstable mountainside, so an emergency preparedness service, the Åknes/Tafjord intermunicipal company (IKS), has closely monitored the area since 2009. Even a smaller slide of about could cross the valley floor, potentially devastating buildings and damaging the Rauma Line railway and European route E136. Such an event could also partially or completely dam up the river Rauma, creating major disruption and a flooding hazard.
During the autumn of 2014, observers became aware of an abnormally large shifting of a portion of the mountain. While it normally shifts by per year, for three weeks that year the movement averaged about per day. As a precaution, on October 22 several houses potentially in the path of a landslide were evacuated and the Rauma Line stopped its four-times-a-day rail service.
During the night of 28 October 2014, the highest part of the mountain shifted as much as . The mountain's slippage was three times as much as the previous night's measurement, and it was the largest motion the observers had seen to date. Geologist Lars Harald Blikra told a news conference that the lower part of the mountain has also increased its rate of motion.
During 19 and 20 September 2015, the upper parts of the mountain began to shift quickly again, moving in one day.
In September 2018, of movement was recorded during 24 hours, the highest measured. Both the 2014 movement, a 2017 movement, the 2018 movement and at more occasions, caused "red" alert, causing temporary evacuation of nearby residents and railway closure.
On 5 September 2019, a very large landslide took place from Mannen.
In total fell that day, in addition to which has fallen as small rockfalls during the previous years. After this landslide, some smaller parts among the debris is still unstable but will not cause a large landslide. It was said that it was the correct action to close the railway and evacuate residents at every one of the 16 red alerts, even if the landslide did not damage any house or the railway.
