Remarks concerning the map and table
The map can be zoomed. The points shown are the highest points of the release area, with the colours indicating the forecast danger level.
The table can be sorted by clicking on the table header.
Notes on the data
All avalanche accidents in which one or more people were caught by the avalanche are included.
Avalanches are not included if:
- nobody was caught in or swept away by the avalanche or everyone involved managed to escape;
- they resulted in damage to property or search operations but no victims were found;
- details of the accident location are very uncertain and/or imprecise.
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.
Interpretation of the data
Avalanche accidents mainly happen where there are many winter sports enthusiasts. This is also reflected in this representation of avalanche accidents. This representation can indicate regions that are particularly prone to accidents. Conversely, places where no accidents have been reported in the last 20 years should not be considered safe. Under correspondingly critical conditions, avalanches can be triggered or spontaneously descend in steep terrain there as well. These accident data are therefore not suitable for tour planning or local assessment of the avalanche situation.
Spotted a discrepancy or error?
Email accidents(at)slf with any additional information that will help us to correct the avalanche details. .ch
Have we missed an avalanche?
Tell us about it, if possible providing photos of the avalanche and a brief description of what happened using the report form. All reports are handled confidentially.
The avalanche locations are based on the information contained in avalanche reports. While we do edit these where necessary, they may still be inaccurate.
- Backcountry touring (e.g. snow-shoeing, mountaineering)
- Off-piste skiing and snowboarding (generally accessed from a ski area)
- Transportation corridors (e.g. ski runs or roads)
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.
