About Avalanche Monitoring
Snow avalanches are among the most dangerous mountain hazards, causing hundreds of fatalities annually worldwide. Calamity aggregates avalanche danger ratings and bulletins from national warning services across major mountain ranges.
Our avalanche data comes from the European Avalanche Warning Services (EAWS) network, including the Swiss SLF, the ALBINA interregional service (Tyrol/South Tyrol/Trentino), Avalanche Canada, the Norwegian Avalanche Warning Service, and the Japan Avalanche Information Network. Danger levels follow the standardized 1-5 European scale.
The CalamityScore for avalanches integrates the regional danger level (1-5), the spatial extent of the warning area, and population exposure in affected mountain valleys. Danger level 4 (High) and 5 (Very High) trigger cascade analysis for burial risk in nearby populated areas.
