Abstract

Summary

Landslides are one of the most common forms of geodynamic hazards, causing significant damage to infrastructure and ecosystems, especially in mountainous regions. This study investigates the influence of geostructural, geomorphological, climatic and anthropogenic factors on the activation of landslide processes in the Ukrainian Carpathians, particularly in the Flysch Carpathians and the Transcarpathian Internal Depression. Using GIS and multiple linear regression, data on 2,325 landslides were analysed and classified according to slope morphotype, geological structure, absolute heights, proximity to watercourses, faults, roads and buildings, as well as microseismicity parameters. The model for the Flysch Carpathians revealed the decisive influence of slope morphology (especially complex and straight forms), high absolute elevations, seismic activity, and anthropogenic factors. Within the Transcarpathian depression, geolithological features and the influence of technogenic disturbances of slope equilibrium are dominant. The results confirm the spatial differentiation of the influence of factors within different tectonic units, which allows the creation of accurate landslide susceptibility maps for regional planning and risk management. The obtained regression models have high coefficients of determination (R2 > 0.79) and can be used for further forecasting of landslide intensification in the context of climate change, increasing urbanisation and seismic activity.
