Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks [1] or suffosion processes. [2] Sinkholes can vary in size from 1 to 600 m (3 to 2,000 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. [3]
A massive sinkhole in Michigan is threatening homes and forcing officials to pump sewage into a river as they race to prevent sludge from filling basements.
Sinkholes can form because of natural or manmade causes, ... but the U.S. Geological Survey conservatively estimates that they have cost on average $300 million per year in damage over the last 15 ...
Thus, the total volume of the silts and clays is reduced, resulting in the lowering of the surface. The damage at the surface is much greater if there is differential settlement, or large-scale features, such as sinkholes and fissures. Aquifer compaction is a significant concern along with pumping-induced land subsidence.
