A descending motion of air in the atmosphere, usually with the implication that the condition extends over a broad area.
This problem, caused when the ground under a building moves downward, often because it has dried out too much, has to be specifically included as a peril under a Fire insurance.
loss of elevation of ground, often caused by sinking after extraction of groundwater or petroleum
The lowering of the Earth's surface, caused by such factors as compaction, a decrease in groundwater, or the pumping of oil.
Slow or rapid sinking of part of the earth's crust that is not slope related.
A sinking or settling of a part of Earth's crust with respect to the surrounding parts.
Surface feature resulting from the collapse of underground mine workings. Subsidences can be either dry, or fill with groundwater or surficial runoff.
Downward movement of structural walls and foundations due to a cause other than self weight of the structure.
Sinking of the land surface caused by removal of water, oil, or minerals from beneath the surface.
Sinking or settling of the ground surface caused when soil or rock collapses into a void. Subsidence can be natural (a sinkhole) or human induced (due to underground mining or pumping of petroleum or water).
Ground movement, usually downward, often as a result of local mining or clay shrinkage in hot weather. (See also Settlement).
The process of sinking to a lower level. For example, the elevation of the land surface above an aquifer may sink or subside when groundwater is withdrawn from the underlying aquifer. Subsidence also refer to the process by which sediment in solution settles out.
the collapsing of underground mines that may cause depressions or holes on the surface and/or damage to structures.
A localized gradual downward settling or sinking of a surface with little or no horizontal movement.
a gradual sinking to a lower level
the sudden collapse of something into a hollow beneath it
Where a property moves due to poor construction or ground movement for geological reasons
Sinking of the land surface due to a number of factors, such as groundwater extraction.
Damage due to land movement, e.g., a house on a hill due to heavy rains. Not earthquake damage.
Sinking of the earth's surface in response to geological or human-induced causes (e.g. mining, extraction of water or petroleum by wells). When subsidence occurs over large areas, the resulting features are termed geosynclines. Non-linear subsidence produces basins and irregular depressions. Subsidence may be counteracted by vertical accretion where sediment-loaded floodwater enters the area.
Movement of the land on which property is situated. A structure built on a hillside may slide down the hill due to earth movement caused by heavy rains. This is different from earthquake damage.
to sink or settle downward; submerge
A descending motion of the air in the atmosphere that usually extends over a rather broad area.
downward settling of the earth's surface
A 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.
Downward or sinking motion of air in the atmosphere. Subsiding air warms due to compression. Increasing temperature and decreasing humidities are present in subsiding air. Subsidence results in a stable atmosphere inhibiting dispersion. Subsidence is generally associated with high atmospheric pressure.
The lowering of the strata, including the surface, due to underground excavations.
The downward movement of air masses where the ground conditions do not favour warming of the air column; precipitation is unlikely to ensue.
A lowering of the land surface in response to subsurface weathering, collapse or slow settlement of underground mines, or the production of subsurface fluids such as ground water or oil.
Ground movement, generally downward, possible a result of mining activities or clay shrinkage.
Sinking air usually found around high pressure systems. Strong subsidence leads to very warm, dry air aloft, often appearing at high elevations first. It may arrive at day or night. Poor humidity recovery at higher elevations is usually a sign of strong subsidence.
The settling or sinking of a surface as a result of the loss of support from underlying soils or strata.
The vertical sinking of the Earth's surface in a region, relative to a reference plane.
(2) a sinking down of a part of the earth's surface due to the collapse of underlying underground openings.
sinking of the land surface due to a number of factors, of which groundwater extraction is one
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.
sinking or falling to the bottom.
sinking (downward) motion in the atmosphere, usually over a broad area
Lowering or sinking of land caused by compaction, wind and water erosion, oxidation of peat soils, and other causes.
The descent of a body of air, usually in a high pressure area, that warms the lower levels of air.
a gradual sinking of land with respect to its previous level
the downward movement of a part of the Earth's crust relative to the surroundings
Sinking air that is associated with warming air and little cloud formation.
Surface caving or sinking of a part of the earth's crust due to underground mining excavations.
progressive sinking of a basin under tectonic strengths often accompanied with a more or less continuous sedimentary filling.
The downward motion of air over a large area resulting in dynamic heating.
the settling of waste piles or other areas at mine sites which causes the surface of the land to sink.
Subsidence is where the ground supporting the foundation of a property shrinks due to a reduction in moisture content, causing the foundations to sink.
Damage to buildings by subsidence is a peril covered by modern houseowners' policies. Subsidence is strictly a vertical downward movement but has been held to include settlement (a lateral movement).
A sinking of an area of the Earth's crust due to fluid withdrawal and pressure decline. TDS Total dissolved solids. Used to describe the amount of solid materials in water.
the vertical fall of earth, usually caused by the loss of underground water or gas support, sometimes resulting from man-made pumping and sometimes from seismic action
The action of land sinking to a lower level
A form of earth movement, excluded in most property policies.
Subsidence is the downward movement of the ground below a building. This may result in cracked walls, movement of walls and foundations and general instability of the building. If a potential client's house shows signs of subsidence, Insurers may be unable to quote.
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.
The is the 'downward movement of the ground below a building'. Its may end up resulting in cracked walls or a general instability of the building. Insurers may be unable to quote if a clients house shows signs of this.
The loss of land elevation due to groundwater or petroleum withdrawal and natural settling. Groundwater withdrawal has been the most important contributor to subsidence for up to nine feet in the Galveston Bay region.
A meteorological term referring to the descending motion of air in the atmosphere, usually extending over a rather broad area, accompanied by warming and drying.
sinking or settling in bone, as in the case of prosthetic component of an artificial joint
Ground movement, possibly as a result of mining activities, clay shrinkage or drainage problems.
In geology, engineering, and surveying, 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. In meteorology, subsidence refers to the downward movement of air.
