Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities Subsidence involves little or no horizontal movement, [1][2] which distinguishes it from slope movement
- Land Subsidence | U. S. Geological Survey - USGS. gov
The occurrence of land subsidence is seldom as obvious as it is in the case of catastrophic sinkholes or mine collapses Where groundwater depletion is involved, subsidence is typically gradual and widespread
- What is subsidence? - NOAAs National Ocean Service
Subsidence - sinking of the ground because of underground material movement—is most often caused by the removal of water, oil, natural gas, or mineral resources out of the ground by pumping, fracking, or mining activities
- Subsidence | Ground Movement, Soil Compaction Land Degradation . . .
Subsidence, sinking of the Earth’s surface in response to geologic or man-induced causes When subsidence occurs in great belts, providing troughs for the accumulation of sediments, the resulting features are termed geosynclines; nonlinear subsidence produces basins and irregular depressions
- What Is Ground Subsidence: How and Why Land Sinks
Ground subsidence is a gradual settling or sudden sinking of the Earth’s surface caused by the removal or displacement of materials underground It can happen slowly over years, dropping land by just a few millimeters annually, or it can occur abruptly when the ground collapses into a sinkhole The process affects cities, farmland, and coastlines worldwide, and in many cases it’s
- Subsidence - an overview | ScienceDirect Topics
Subsidence is defined as the downward vertical movement of the Earth's surface, which can occur due to natural processes or human activities, such as groundwater withdrawals
- General Concept – UNESCO Land Subsidence International Initiative
Subsidence (land surface sinking) occurs in many parts of the world, particularly in densely populated deltaic regions, causing extremely expensive damage
- Mapping the global threat of land subsidence | Science
Subsidence, the lowering of Earth's land surface, is a potentially destructive hazard that can be caused by a wide range of natural or anthropogenic triggers but mainly results from solid or fluid mobilization underground
