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.

Groundwater extraction is one of the primary drivers of coastal subsidence. Cities and industries are pumping water from underground aquifers faster than it can be replenished, a situation ...

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 ...
Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface creates voids (i.e., caves).If the roof of a void becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface.
Nearly half of China’s urban areas comprising 29% of the country’s population are sinking faster than 3 millimeters per year, according to a new study.
Mexico City subsidence. Groundwater-related subsidence often results in major damage to urban areas. In Mexico City, the buildings interact with the settlement, and cause cracking, tilting, and other major damage. [7] In many places, large sinkholes open up, as well as surface cavities.
