Gugla-Längenschnee_C (VS)

Landslide

Elevation: 2950-3100m - Massif: Valais Alps (Mischabel) - Commune: St-Niklaus (VS)  

The motion of this landslide, located at an altitude of about 3000 m a.s.l. on the western slope of the Gugla summit, has dramatically increased in 2018. In situ survey is permanently undertaken by means of a first GNSS station installed in 2016. Permafrost is likely to occur in the whole moving mass. A bit southward occurred a large landslide already in 1959, which caused the evacuation of the hamlet of Herbriggen.
