Number of avalanche fatalities per hydrological year in Switzerland since 1936-1937

Attention: this data is not updated after 2022 anymore. This dataset contains the statistics on the number of avalanche fatalities per hydrological year in Switzerland. The data set commences with the beginning of the hydrological year 1936/37 on 01/10/1936. After the completion of a hydrological year, the new data is appended to the existing dataset.

The following information is contained (by column and column title):
- hydrological year
- number of fatalities in the backcountry (=tour)
- number of fatalities in terrain close to ski areas (=offpiste)
- number of fatalities on transportation corridors including ski runs, roads, railway lines (=transportation.corridors)
- number of fatalities in or around buildings or in settlements (= buildings)
- sum (of all four categories)

The definition for these four categories as described in the guidelines to the avalanche accident database:

tour:
activities include back-country ski, snowboard or snow-shoe touring

offpiste:
access from ski area, generally from the top of a skilift with short hiking distances

transportation.corridors (Techel et al., 2016):
people travelling or recreating on open or temporarily closed transportation corridors (e.g. a road user or a skier on a ski run) and people working on open or closed transportation corridors (e.g. maintenance crews on roads, professional rescue teams)

buildings (Techel et al., 2016):
people inside or just outside buildings, and workers on high alpine building sites
