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.

Dozens of cities along the US coastline are sinking at alarming rates, leaving them far more exposed to devastating flooding from sea level rise than previously thought, scientists reported ...
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.
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. Though home damage from ...
