Description :
Sinkholes occur throughout the Campania territory both in soils and in rocks. Sinkholes in strongly karstified carbonate massifs are described by means of geological and geomorphological analyses. The interpretation of air photographs and topographic maps allowed the recognition of 77 sinkholes which were catalogued on the basis of their main morphometric features (depth, axial length, volumes, etc.) and geological (lithological, structural) and hydrogeological context. These data suggest high instability conditions along the slopes affected by sinkhole formation and evolution. In a few cases it was possible to establish that collapse sinkholes formed in historical times triggered by strong earthquakes. This may be taken into account for the construction of underground works or for territorial planning.
