This data collection contains information concerning all known accidents by snow avalanches in Switzerland with at least one fatality. The data set commences on 01/10/1936. After the completion of a hydrological year, the new data is added.
The following information is provided:
* avalanche identifier
* date of the accident
* accuracy of the date in range of days before and after
* hydrological year (always from first of october to end of september)
* canton
* municipality
* start zone point latitude
* start zone point longitude
* start zone point accuracy (in meters)
* start zone point elevation (in meteres above sea level)
* slope aspect (main orientation of start zone)
* slope inclination (in degree, steepest point within start zone)
* forecasted avalanche danger level 1 (first danger)
* forecasted avalanche danger level 2 (second danger)
* accident within the core zone (most dangerous aspect and elevation as mentioned in the forecast)
* number of dead persons
* number of caught persons
* number of fully buried persons
* activity/location of the accident party at the time of the incident
