Abstract
The development of mountainous areas leads to activation of hazardous exogenic processes, primarily landslides and mudflows. One of the important factors determining the intensity of these processes and having a significant impact on their characteristics is moistening of rocks in potential landslide and mudflow masses. This work considers the case of landslide activation at Gornyi Vozdukh ski resort in December 2021. A predictive model is presented for the formation of landslides induced by excessive moistening of slopes, which was calibrated to the conditions of southern Sakhalin. To calibrate the model, the data on the cases of landslides and mudflows within a 30-km radius from Yuzhno-Sakhalinsk hydrometeorological station are collected. The predictive model uses data on daily, antecedent, and cumulative precipitation. All these data are publicly available, which makes it possible to calibrate the model for any nearest hydrometeorological station. The daily precipitation threshold making possible the formation of landslides and mudflows in the given territory is determined as 51.4 mm.
期刊介绍：
Russian Journal of Pacific Geology publishes the results of research on the Earth crust and mantle composition and provides articles on the geological structure and patterns of distribution of mineral deposits in the Pacific Ocean, marginal seas and continental margins. It discusses the topics of stratigraphy, sedimentology, magmatic activity, and seismicity. The journal deals with the problems of lithosphere plates tectonics, and offers the results of neotectonic, geomorphological, geodesic, environmental and mining studies in the Pacific region. The journal accepts theoretical, methodical and philosophical articles covering general issues of geology, geophysics, geochemistry, geoecology and mining. The journal also publishes critical notes and comments, and reviews.
