چکیده

An assessment of the landslide risk (Rls) for territory Bulgaria by administrative districts has been made combining vulnerability (V) and hazard (Hls) maps. Landslides are a significant part geological hazards widespread throughout country. In order to assess Bulgaria, it is necessary take into account not only all landslides given region, but also its vulnerability, thus level this Rls = f (V, Hls). Landslide determined matrix, using selected indicators weighting coefficient hazard. Assessing region subjected key component assessment. These include exposure infrastructure, industrial facilities production capacity, residential buildings, regional GDP per capita potential human disability (defined population density in district). The data used combined create map showing each district. Indicators density, GDP, length road railway networks number buildings were vulnerability. district intensity processes district, depending on their activity affected area. normalized (distributed) an area region. categorized as active, stabilized. results express weighted average rated from 1 5, where means no 5 that very high (very hazard). degree turn leads possible economic losses, social environmental consequences (landslide risk). (level) assessed low, medium, high, shown relevant
