Switzerland Landslide Hazard by Cantons - Opendata.swiss

Hazard maps indicate the locations in Switzerland where settlements are threatened by floods, avalanches, landslides and fall processes. Currently, 99% of the area to be mapped has been surveyed for avalanche hazards, 97% for flood hazards, 90% for landslide hazards and 91% for hazards from fall processes throughout Switzerland. The federal authorities support the cantons in the development and updating of the hazard maps. The map shows the state of natural hazard mapping relating to landslides.
