Spatial planning instruments

Maps are fundamental to the work of avalanche commissions. In addition to weather, terrain, and forest maps, specialized spatial planning tools—such as hazard maps—play a crucial role in evaluating and interpreting local avalanche risk.

Avalanche protection and climate change

Climate change and shifting weather and precipitation patterns are increasingly altering the dynamics, frequency, and characteristics of avalanches. As a result, avalanche commissions – serving as key actors in local risk management – are facing evolving and increasingly complex challenges.

Act – Measures: Artificial Avalanche Triggering

The targeted artificial triggering of avalanches is an effective method for minimizing avalanche risk. For this porpuse, various techniques are available, ranging from purely mechanical methods to the use of explosives and gas mixtures.

Permanent technical avalanche protection and its limits

Permanent technical avalanche protection comprises various structural measures designed to protect against avalanches. One of the responsibilities of avalanche commissions is to understand the functioning and the limitations of these protective measures; in addition, their continuous monitoring plays a crucial role.

Act – Measures: warnings, closures, and evacuations

To mitigate avalanche risk, avalanche commissions have a range of measures at their disposal, including warnings of increased avalanche danger, road closures, the evacuation of people, or combinations of these measures. These measures aim to reduce the exposure of people and assets to avalanches and thereby decrease their vulnerability.

Perceive: using data and doing observations

05.12.2025 Effective avalanche risk management relies on situational awareness, involving data analysis (e.g. weather, maps, bulletins…) and field observation (e.g. local condition, terrain, snow profiles…)
