Chronological database of sinkholes in Italy

focus-sinkholes-evidenza Sinkholes occurrence is related to the presence of an underground cavity, from which instability starts and propagate upwards until causing the collapse of the surface soil layer. The cavity may have a natural or artificial origin. Natural caves are due to presence of soluble rocks, and are typical of karst settings, where most of the sinkholes occur for dissolution processes. Man has excavated Anthropogenic cavities, for different purposes and ...

DInSAR techniques for the assessment of sinkhole hazard

OLYMPUS DIGITAL CAMERA Sinkholes occur as sudden collapses of the ground, related to natural cavities produced by karst processes in soluble rocks, or to man-made cavities deriving from different types of human activities in different historical ages. Sinkholes are widespread all over the world, and the related hazard is extremely high, with very severe damage to built-up areas and human infrastructures, and heavy losses to the ...

GIS technologies for managing sinkhole hazard

GIS_sinkhole- The widespread sinkholes that involve large sectors of the Apulian territory are related to natural cavities produced by karst processes in soluble rocks, or to man-made cavities deriving from different types of human activities in different historical ages. The related hazard is extremely high, with very severe damage to built-up areas and human infrastructures, and heavy losses to the ...

Hazards in karst areas and mitigation strategies

OLYMPUS DIGITAL CAMERA The high fragility of karst terrains, and the deriving vulnerability to a number of possible events, together with the presence of significant natural (first and foremost, groundwater), landscape and historical resources, are at the origin of the project activities, aimed at the safeguard of karst environments and the mitigation of the related ...
