Common standards form the foundation for collaboration between the European Avalanche Warning Services. The EAWS are constantly working on improving and standardizing their operating procedures and services.
Avalanche Danger Scale
In 1993, the European Avalanche Warning Services agreed on a common five-level avalanche danger scale, this was an important milestone in the history of the EAWS. The five danger levels were later introduced worldwide and today form the standard reference of modern avalanche forecasting.
The five avalanche problems of the European Avalanche Warning Services represent five typical situations that can be encountered in the winter backcountry. Avalanche problems aim to support both recreationists and professionals in their evaluation of the avalanche danger.
The avalanche bulletins published by the European Avalanche Warning Services are uniformly structured along the so-called information pyramid. The most generalized information forms the top of the pyramid, the information content and level of detail increases towards the bottom.
The EAWS Matrix is a tool used by the European Avalanche Warning Services to determine the regional avalanche danger level. It helps the forecaster to assess the avalanche danger more objectively and thus increases the consistency of the danger level across borders.
The primary purpose of European Avalanche Warning Services (EAWS) is to support its Members in preventing the loss of lives and damage due to avalanches by providing the society with efficient and effective avalanche forecasting and warning services.
