Subsidence is the motion of a surface (usually, the Earth's surface) as it shifts downward relative to a datum such as sea-level. The opposite of subsidence is uplift, which results in an increase in...

In the areas of southern California where ground subsidence has been reported, the phenomenon is usually associated with the extraction of oil, gas or ground water from below the ground surface, or the organic decomposition of peat deposits, with a resultant loss in volume.

We see evidence of continued differential subsidence of the land surface over the crater in the geology and topography of the modern land surfaces around the bay. First look at the geology.

Land subsidence occurs when large amounts of ground water have been withdrawn from certain types of rocks, such as fine-grained sediments. The rock compacts because the water is partly responsible for holding the ground up.

The paper aims at highlighting the problem of ground subsidence in the Himalayan terrain together with the hardships of the victims. All these habitations are being affected by ground subsidence and the inhabitants of these villages are facing severe resource crisis.

Underground mining causes costly subsidence damage world-wide. In the 1980s German mining research developed stowage techniques using mining wastes during longwall mining operations. These were applied successfully, but not continuously because of economic considerations at that time.
