ANALYSIS OF SPATIAL PATTERNS OF LANDSLIDE FORMATION WITH GIS TOOLS (ZAKARPATSKA OBLAST)

To identify the primary and derived geological factors determining spread activation of landslides within Zakarpatska Oblast, a database 2.575 were collected integrated into GIS, with total area 385.21 km2 covered. Using ArcView Spatial Analyst environment, landslide formation represented by constructed grids relief, its derivatives, density structural-tectonic heterogeneities have been examined. It has established that development maximum occurs at heights hypsometric marks 280–730 m, slopes 7.5–22.4° steepness, oriented to west, south-west, south, south-east located distance up 500 m from watercourses. Two-thirds all analyzed are kilometer zone along disturbances 1250 disorders 90–180° azimuth. The approach applied made it possible establish for first time ever patterns occurrence, relying on results processing large array cartographic information, obtain probable limit values characterizing factors, as well build an iterative regional predictive model forecasting hazards occurrence. Mapping areas characteristic determined will be used local forecasts. implemented in measures reduce risk hazardous processes Oblast.
