General recommendations before a mass movement

Consult the available resources, in particular the  hazard map for your area. The hazard maps show the areas in Switzerland that are endangered by natural hazards. Many cantons make their hazard maps accessible on the Internet. The cantonal natural hazard agencies, communes and in some cases the local emergency services can provide information on the endangered areas.

If you live in an area that is exposed to the danger of landslides, shallow landslides, debris flows or rockfalls, it is crucial to take precautions in good time and keep the resources you need to hand:

For existing or new buildings

For existing buildings in endangered areas, following the planning advice.

  • It is essential that new buildings are erected only outside the danger zones.
  • Carry out structural works: Reinforce foundations and external walls, install permanent protection for openings such as windows and doors. Consult experts on questions concerning the precautions.
  • Have rainwater diverted.
  • Modify the interior layout: rooms on the endangered slope side of the building should only be used for short periods of time.
  • Modify the exterior layout: place seating areas, balconies etc. against the exterior wall facing away from the potential landslide.
  • Find out about the existing emergency plans from the authorities where you live and work.

For land outside existing residential areas

  • Stabilise landslide-prone slopes by planting deep-rooted trees and shrubs.
  • Divert rainwater (drain the slope).
