Land subsidence is a gradual settling or sudden sinking of the Earth's surface owing to subsurface movement of earth materials. The principal causes of land subsidence are aquifer-system compaction, drainage of organic soils, underground mining, hydrocompaction, natural compaction, sinkholes, and thawing permafrost. For example, sea level rise contributes to saltwater intrus Oct 27, 2011 · How Sinkholes Develop in Florida and the Gulf Coast Sinkhole activity is a geologic function that naturally occurs over thousands of years.
