Abstract
Cases of building decay and structural damage caused by the impact of snow loads are registered every year throughout the world. Such destruction not only results in property loss, but also leads to human losses. A database on 266 cases of roof collapse caused by snow loads in Russia for the period from 2001 to 2021 was collated for this study. The data were analyzed by date and place of collapse, building data, and number of victims. The analysis showed that civilian buildings are the most vulnerable, comprising 78% of the total number of collapses, followed by industrial buildings with 15% and agricultural buildings with only 7%. The relationships between roof shape, roofing material, number of floors, and type of collapsed building were determined. The data processing results showed that low-rise residential buildings (one to two floors) with a gable roof covered with fiber cement should be considered the most vulnerable. A linear relationship was revealed between a collapse area of more than 150 m2 and the cumulative number of collapse cases. The obtained results have practical application for rating building vulnerability to natural hazards and assessing the risk of emergencies associated with snow loads.

Summary
Far East Geological Institute, Far Eastern Branch of the Russian Academy of Sciences, Sakhalin Branch, Abstract: Cases of building decay and structural damage caused by the impact of snow loads are registered every year throughout the world. Such destruction results in property loss, and leads to human losses. The repeated collapse of and damage to buildings as a result of snow loads lead to a problem in their calculation and mapping [1,2,3,4,5,6,7,8]. Geis et al [12] estimated that at least one out of every 48,000 buildings in the United States experiences roof collapse due to snow during its lifetime
