- Аннотация: The paper considers accidents triggered by the impacts of debris flows on the infrastructure. The information collected by the author in the database of technological and natural–technological accidents and emergency situations (NTES) occurred in the Russian Federation from 1991 to 2020 is analyzed. The concept of emergency situation is used to collect data. The majority of accidents are caused by debris flows of rain origin. The classification of NTES due to debris flows is proposed based on the type of the infrastructure disrupted and cascading accidents. Eight types of NTES are revealed. Linear structures are most exposed and vulnerable to these impacts. The most affected are facilities of the transport infrastructure, as well as power lines, pipelines, lines of communication, and other life-lines. An average annual frequency of occurrences of these accidents and disruptions was estimated; areas most at risk were identified; seasonal variation of events was investigated. These accidents occur most frequently (once every 2–6 years) in Sakhalin and the North Caucasus debris flow provinces. The proportion of accidents triggered by debris flows inthe total number of NTES is relatively small (about 2%); however, they cause the large damage and social problems creating emergency situations not only in the disaster areas but also in other areas connected by damaged linear structures. The majority of accidents occur during the warm season: from May to August in the North Caucasus and from Juneto October in the Pacific and Eastern regions.
