Land Subsidence in the United States (U.S. Geological Survey Circular, 1182)

By Devin Galloway

Land subsidence (LS) is a gradual settling or sudden sinking of the Earth's surface owing to subsurface movement of earth materials. More than 80% of the identified LS in the nation is due to our exploitation of underground water (UW). This report illustrates the 3 basic mechanisms by which human influence on UW causes land subsidence: compaction of aquifer systems, dewatering of organic soils, and mass wasting through dissolution and collapse of susceptible earth materials. Also examines the role that water-management groups play in mitigating subsidence damages. Color and B & W photos, maps, and drawings.
