Localized collapse of the land surface usually due to erosion of the underlying materials. Most commonly occurring in karst areas, but similar effects occur due to physical erosion in other terranes.
Describes and provides several detiled examples of impacts of human-induced land subsidence resulting from the extraction of subsurface water, including aquifer-system compaction, drainage of organic soils, dissolution and collapse of susceptible rocks.
Uses and availability of limestone and related commodities such as lime and portland cement. Hazards of limestone terranes due to erosion and sinkhole formation.
