Remarks concerning the table and map

The map can be zoomed.

The table can be sorted by clicking on the table header.

The shown points are the highest points of the release area.

Notes on using the data

The data is based on the information submitted by rescue services and SLF observers as well as on the detailed investigation conducted by the police. The table will normally be updated at the beginning of each new hydrological year.

The initial data on the individual accidents contained in the table have not been verified in detail. For this reason, some of the information may be inaccurate. The exact sequence of events is analysed by the police, which generally takes several months. Their findings (e.g. precise location of the accident, sequence of events) are subsequently reflected in the content of our accident reports, in the accident database and in the overview of the accidents of the last 20 years.

Date and location of avalanche starting zone

In some cases the day of the accident and the exact location of the avalanche starting zone was unknown. In these cases, date and starting zone location had to be estimated.

Activity, location

  1. Backcountry touring (incl. for instance snow-shoeing, mountaineering)
  2. Off-piste skiing and snowboarding (access generally from a ski area)
  3. Transportation corridors (including for instance ski runs or roads)
  4. Buildings


shown is the number of fatalities and, in brackets, the number of persons caught and fully buried

Danger level

The forecasted danger level is shown in the table with the following notations:

  • (3) - danger level 3, but location of accident not within the most dangerous aspects and elevations as given in the bulletin;
  • 2↗3 - increasing danger level during the day if two danger levels were given (examples: increasing danger with new snow and wind, or double map with danger level for dry and wet avalanche danger)
