Spread, activity and danger of landslide processes in the Otradnensky district of the Krasnodar Krai

The object of the study is landslide activity in the Otradnensky District of the Krasnodar Krai. The paper presents the results of systematization and analysis of various sources containing information about the distribution and of the activity manifestation of landslide processes (for the period 2005–2024) in the studied municipal district. The conditions, causes, extent, activity, and danger of landslide manifestations in the district are characterized. The role of natural and anthropogenic factors in the development of this process is determined. Some qualitative and quantitative (area, power) characteristics of large landslide masses developed in the territory of the district are given, and a brief description of the soils that form them is provided. The analysis of landslide activity for 2005–2024 showed significant development of active landslide forms, both by year and by the studied territory. The highest landslide activity was observed in 2018, while very low activity was recorded in 2016, 2022–2024. It is noted that of landslide manifestations most often occur on the ledges of the high terraces of the Urup River and its tributaries, mostly without causing significant damage to residential and commercial facilities. The article provides information about the extent of landslide deformations and destructions on the highways of the district. Over the past 20 years, no emergencies caused by landslides have been reported in the study area. The identified landslide activations observed in the district during this period, as well as the analysis of the socio-economic aspects of their consequences, suggest a significant level of landslide activity in the Otradnensky District of the Krasnodar Krai.
