Avalanche accidents in Switzerland since 1970/71

**When using this data, please consider and adhere to the associated [Terms of Use](https://www.slf.ch/en/services-and-products/data-and-monitoring/slf-data-service.html)**. This data collection contains information concerning all known accidents by snow avalanches in Switzerland with at least one person involved (caught). The data set commences on 01/10/1970. 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 * 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使用本数据集时，请遵守关联的[使用条款](https://www.slf.ch/en/services-and-products/data-and-monitoring/slf-data-service.html)。 本数据集收录了瑞士境内所有已知的雪崩事故信息，此类事故均造成至少1人被雪崩卷入（捕获）。数据集起始时间为1970年10月1日，每个水文年度结束后将追加新增事故数据。 本次提供的信息包括： * 雪崩标识符 * 事故发生日期 * 日期精度（前后误差天数范围） * 州（Canton） * 市镇 * 雪崩起始区点位纬度 * 雪崩起始区点位经度 * 起始区点位精度（单位：米） * 起始区海拔高度（单位：米，相对于海平面） * 坡向（雪崩起始区的主朝向） * 坡度（单位：度，指起始区内最陡点的坡度） * 雪崩预警等级1（首次预警等级） * 雪崩预警等级2（二次预警等级） * 事故发生于核心预警区内（即匹配预警中提及的最危险坡向与海拔范围） * 遇难者人数 * 被卷入雪崩人数 * 完全被掩埋人数 * 事故发生时涉事团队的活动类型与所处位置
