The opposite of isostatic subsidence is known as isostatic rebound—the action of the crust returning (sometimes over periods of thousands of years) to a state of isostacy, such as after the melting of large ice sheets or the drying-up of large lakes after the last ice age. Lake Bonneville is a famous example of isostatic rebound.
Land subsidence in the Central Valley is monitored by various government agencies including NASA, the California Department of Water Resources, the USGS, and various local agencies or businesses within the valley. The NASA Jet Propulsion Laboratory uses InSAR to remotely measure topographic change over time. In a monitoring study from May 2015 ...
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-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.
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 ...
They may fund government services, direct payments to citizens, a rainy-day fund, or specific infrastructure projects. A version can be found in oil-rich Alaska, where its $80 billion sovereign ...
Tectonic subsidence is the sinking of the Earth's crust on a large scale, relative to crustal-scale features or the geoid. [1] The movement of crustal plates and accommodation spaces produced by faulting [2] brought about subsidence on a large scale in a variety of environments, including passive margins, aulacogens, fore-arc basins, foreland basins, intercontinental basins and pull-apart basins.
Term Description Examples Autocracy: Autocracy is a system of government in which supreme power (social and political) is concentrated in the hands of one person or polity, whose decisions are subject to neither external legal restraints nor regularized mechanisms of popular control (except perhaps for the implicit threat of a coup d'état or mass insurrection).
