ASSESSMENT OF LANDSLIDE HAZARD IN BULGARIA USING GIS

The territory of Bulgaria has a high degree of landslide hazard with possible economic losses, social and environmental consequences. The Landslides are widespread throughout the country's territory. They form the most serious part of the geological hazard in Bulgaria. The main factors for landslide activity (rainfall, impact of surface and ground water, abrasion (sea erosion), erosion and earthquakes) around different regions in Bulgaria using the GIS data analysis are presented in this study. The purpose of the study is to provide an analysis for the assessment, forecasting and prevention of natural and anthropogenic risks and disasters and for inclusion in European networks and projects for the development of Earth sciences. Work is underway on structuring the database, collecting information on dangerous geological processes in the country and introducing them into the GIS environment.
