Mine subsidence is a risk in areas where old mining sites exist. It is a type of surface-level ground movement that happens when there is an underground collapse or shift.
Drivers, processes, and impacts of sinking cities [1]. Sinking cities are urban environments that are in danger of disappearing due to their rapidly changing landscapes.The largest contributors to these cities becoming unlivable are the combined effects of climate change (manifested through sea level rise, intensifying storms, and storm surge), land subsidence, and accelerated urbanization.

Subsidence (the sinking of land) may occur after considerable production of oil or ground water. Oil, and, less commonly, gas extraction, has caused land subsidence in a small percentage of fields. Significant subsidence has been observed only where the hydrocarbon reservoir is very thick, shallow, and composed of loose or weakly cemented rock ...
Land subsidence is a global issue and has different causes. Some are natural, like earthquakes , and some are caused by humans. In the United States, land subsidence from over pumping has affected 45 states and accounts for changes in over 17,000 square miles of land which is an area almost 10 times the size of Glacier National Park in Montana ...
A new study led by scientists at the University of Miami has revealed that 35 buildings along the Miami Beach to Sunny Isles Beach coastline are experiencing subsidence, where the ground is either ...
Groundwater-related subsidence is the subsidence (or the sinking) of land resulting from unsustainable groundwater extraction.It is a growing problem in the developing world as cities increase in population and water use, without adequate pumping regulation and enforcement.
Subsided house, called The Crooked House, the result of 19th-century mining subsidence in Staffordshire, England Mam Tor road destroyed by subsidence and shear, near Castleton, Derbyshire. Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities ...
The Intergovernmental Council for the International Hydrological Programme (IHP) created a Working Group on Land Subsidence for liaison of IHP subproject 8.4, "Investigation on land subsidence due to ground-water exploitation." in April 1975. [2] This first WGLS was composed by: Mr. Joseph F. Poland, Chairman. U.S. Geological Survey, USA. (Chair)
