Notes on the data

All avalanche accidents in which one or more people were killed in the avalanche are included.

The avalanche events shown are reported by observers, the police, the emergency services and members of the public. The reports are checked for plausibility by SLF staff and corrected if necessary, but may contain inaccuracies or omissions. The table is updated regularly but not daily.

Spotted a discrepancy or error?

Email accidents(at)slf.ch with any additional information that will help us to correct the avalanche details.


The avalanche locations are based on the information contained in avalanche reports. While we do edit these where necessary, they may still be inaccurate.

Activity, location

  1. Backcountry touring (e.g. snow-shoeing, mountaineering)
  2. Off-piste skiing and snowboarding (generally accessed from a ski area)
  3. Transportation corridors (e.g. ski runs or roads)
  4. Buildings

Danger level

The forecast 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 (e.g. double map with danger level for dry and wet avalanche danger)

The map shows the relevant danger level for the day of the accident. A link to the bulletin can be found in the pop-up window.
