natural geomorphological hazards, total hazard value, cumulative effect of hazards, hazardous regions, Slovakia

The chapter is focused on an assessment of spatial distribution and mutual relations of the most marked natural geomorphological hazards in Slovakia. There are defined areas threatened by partial hazards, namely by earthquakes, landslides and related phenomena, karst and mining subsidence and collapsing, snow avalanches, wind erosion, water erosion, regional and local floods, as well as muddy floods. Consequently, the spatial structure of combinations of extreme values of various hazard types from the viewpoint of their possible synergetic operation and multiplication effect is analysed. Finally the authors present synthetic characteristics of hazards and delimit basic hazardous regions. Typifying the Slovak area from the viewpoint of various types of natural geomorphological hazards represents the result, which is utilisable in the process of landscape planning at a regional level.
