oa Landslide Inventories and Key Hazard Drivers in the Ukrainian Carpathians: The Upper Latoritsa Basin Case

A landslide inventory database was developed for the Upper Latoritsa basin, Mukachevo district of the Transcarpathian Region in Ukraine. Comprehensive analysis using remote sensing data, detailed field-based geological and geomorphological surveys, GIS tools, and statistical methods allowed for a thorough assessment of the influence of geological and geomorphological factors on the development of landslides. Spatial and temporal patterns of landslides were identified, confirming their complex, multifactorial genesis. The results confirm a strong spatial correlation between landslides and fault systems of various origins, with most landslides occurring within 100–500 meters of fault zones. This highlights the key role of structural-tectonic features and destructive processes in the initiation and propagation of slope instability. Terrain parameters such as slope steepness, curvature, topography wetness index and elevations were identified as critical contributors to landslide susceptibility, as they directly affect shear and normal stress conditions within landslide bodies. Seismicity was also found to be an important triggering factor. The results of the conducted research serve as a scientific basis for forecasting landslide hazards and assessing associated risks, they provide essential insights for land-use planning and effective georisks mitigation in the Carpathians.
