The gradual caving in or sinking of an area of land,
  1. The gradual caving in or sinking of an area of land

  1. remission: an abatement in intensity or degree (as in the manifestations of a disease); "his cancer is in remission"
  2. settling: a gradual sinking to a lower level
  3. cave in: the sudden collapse of something into a hollow beneath it
  4. 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 elevation. Ground subsidence is of concern to geologists, structural engineers and surveyors.
  5. Subsidence in the Earth's atmosphere is most commonly caused by cold temperatures: as air cools, it becomes denser and moves towards the ground, just as warm air becomes less dense and moves upwards. ...
  6. The process of becoming less active or severe; A sinking of something to a lower level, especially of part of the surface of the Earth due to underground excavation or seismic activity
  7. Decrease in the elevation of land surface due to tectonic, seismic, or artificial forces, without removal of surface material.
  8. A sinking or downward motion of air, often seen in anticyclones. It is most prevalent when there is colder, denser air aloft. It is often used to imply the opposite of atmospheric convection.
  9. Sinking air that is associated with warming air and little cloud formation.
  10. Where a property moves due to inadequate foundations or severe change to the underlying ground resulting in an instability in the structure of a building often evidenced by cracks in walls.
  11. A form of earth movement, excluded in most property policies.
  12. Sinking (downward) motion in the atmosphere, usually over a broad area.
  13. Ground movement, generally downward, possible a result of mining activities or clay shrinkage.
  14. Settling of the ground surface caused by the collapse of porous formations that result from withdrawal of large amounts of groundwater, oil, or other underground materials.
  15. The lowering of the soil level caused by shrinkage of organic layers. This shrinkage is due to desiccation, consolidation and biological conditions.
  16. The slow sinking of air, usually associated wit high-pressure areas.
  17. Sinking of the land surface due to a number of factors, including ground water extraction.
  18. A sinking of an area of the Earth's crust. In geothermal applications, this is usually due to fluid withdrawal and pressure decline.
  19. Sinking of land surface caused by natural factors such as tectonic shifts or by human activities such as groundwater withdrawals or oil and gas extraction
  20. Sinking or settling of soils so that the surface is disrupted, creating a shallow hole.
  21. island sinking due to lithospheric flexure
  22. The permanent movement of land down (subsidence) or up (uplift) due to geologic processes, such as during an earthquake.
  23. A sink hole. Sinkholes are characterized by the ground falling away due to the collapse of underground caverns or washouts.
  24. The gradual sinking, or sometimes abrupt collapse, of the rock and soil layers into an underground mine. Structures and surface features above the subsidence area can be affected.
  25. Subsidence is when the elevation of the ground drops slowly over time as water is pumped out and used for commercial and domestic uses. Since 1973 most of Harris County has fallen 1 foot with some areas falling as much as 5 feet. ...
