Land subsidence is defined as the lowering of the land surface. Many different factors can cause the land surface to subside. Subsidence can occur rapidly due to a sinkhole or under ground mine collapse, or during a major earthquake. Subsidence can also take place slowly, becoming evident over a time span of many years. In either situation, subsidence can result in millions of dollars of damage. Find out more about causes of land subsidence by clicking on the links below.
