avalanche_hazard_deposition: Modeled depth of snow deposited by avalanches, in meters (m). Available for four scenarios: Frequent Historical (1981-2010), Rare Historical (1981-2010), Frequent Future, and Rare Future. Frequent scenarios have an estimated return period of less than 30 years, and rare scenarios have an estimated return period between 30 and 300 years. Historical scenarios represent climate conditions from 1981 to 2010, and future scenarios represent projected future climate conditions. avalanche_hazard_max_pressure: Modeled maximum impact pressure of avalanches, in kilopascals (kPa). Available for four scenarios: Frequent Historical (1981-2010), Rare Historical (1981-2010), Frequent Future, and Rare Future. Frequent scenarios have an estimated return period of less than 30 years, and rare scenarios have an estimated return period between 30 and 300 years. Historical scenarios represent climate conditions from 1981 to 2010, and future scenarios represent projected future climate conditions. avalanche_hazard_extent: A simple extent of the modeled avalanche area. Available for four scenarios: Frequent Historical (1981-2010), Rare Historical (1981-2010), Frequent Future, and Rare Future. Frequent scenarios have an estimated return period of less than 30 years, and rare scenarios have an estimated return period between 30 and 300 years. Historical scenarios represent climate conditions from 1981 to 2010, and future scenarios represent projected future climate conditions.

The Alaska Snow Avalanche Hazards Database centralizes standardized data layers that describe snow and terrain conditions, potential release areas, and modeled avalanche extents for Alaska, where steep terrain, deep snowpacks, and exposed communities and transportation corridors make avalanches a recurring hazard. It supports evidence-based land-use planning, transportation, resource management, and risk-reduction decisions across avalanche-prone areas of the state, particularly where field-based hazard mapping is limited.
