Hazards in karst areas
Karst. All processes, forms, and landscape related to dissolution and efficient underground drainage in soluble rocks (e.g., limestone, dolomite, marbles, chalk, gypsum, or salt).
Karst hazards. Natural and human-induced hazards in karst areas, connected with the nature of karst.
Collapse. The gradual or rapid failure of roof rock or caprock into an underground cavity manifested on the surface by collapse (natural) or subsidence (human-induced) sinkholes.
Subsidence. The process of gentle and continuous surface deformation, manifested on the surface by shallow depressions.
Karst hazardsare an important example of natural hazards. They occur in areas with soluble rocks (carbonates, mostly limestone, dolomite, and chalk; sulfates, mostly gypsum and anhydrite; chlorides, mostly rock salt and potassium salt; and some silicates, quartzite and amorphous siliceous sediments) and efficient underground drainage. Karst is one of the...
