A giant fault threatens a Swiss village

The Val d'Anniviers is a Swiss valley particularly exposed to natural risks, as proven by the appearance of a 250-meter-long fault in October 2025. This fissure is caused by ground subsidence triggered by the lowering of the Navizence riverbed during successive floods. The unstable mass is estimated at 500,000 cubic meters, which forced the authorities to plan the evacuation of the municipality of Chippis.
