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.

Pulau Bukom, also known as Pulau Bukum (Chinese: 毛广岛; Tamil: புளு புகோம்), is a small restricted-access island belonging to Singapore that is located about five kilometres to the south of Mainland Singapore, off the Straits of Singapore. The size of Pulau Bukom is about 1.45 km 2 (0.56 sq mi).
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.
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 ...
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.
Located along Thomson Road in Novena, Singapore, the station is located near landmarks such as Tan Tock Seng Hospital, Mount Elizabeth Novena Hospital and United Square. Planned as part of Phase One of the MRT system, under the working name Thomson, the station's name was changed to Novena in November 1982, after the Novena Church.
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.
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)
