About 2,250 additional people in Wilmington will be exposed to high-tide flooding if subsidence continues at the same pace, the researchers found, with the value of homes exposed to flooding in ...

Mexico City is an example of a sinking city that is neither coastal nor low-lying. The city was originally constructed by the Aztecs above a large aquifer in the 1300s. Subsidence was originally caused by the loading of large Aztec and Spanish structures. The city grew rapidly during the nineteenth century, and with it, so did the demand for water.
[5] [6] Total subsidence can usually be determined by ground-surface elevation surveys and GPS measurements. Potential impact on the aquifers and other resulting geohazards such as fissures can be assessed through long-term hydrologic studies and models. Mexico City subsidence. Groundwater-related subsidence often results in major damage to ...
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.
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.
Researchers said the main cause behind the sinking was vibrations from construction, which can cause soil particles to compact and settle, resulting in subsidence – the gradual sinking of land.
