subsidence
含义: The gradual sinking or settling of the ground surface, caused by the removal of underground material, drying of clay soils, mining activity, or natural geological processes.
Subsidence is a significant concern for British homeowners, particularly in areas with shrinkable clay soils in south-east England, where prolonged dry spells cause the ground to contract. Tree roots — especially from oaks and willows — can exacerbate the problem by drawing moisture from the subsoil. Former mining areas across Wales, the Midlands, and northern England also suffer from subsidence as old workings collapse. Insurance claims for subsidence run into hundreds of millions of pounds annually. It collocates with 'ground,' 'mining,' 'clay,' 'structural,' and 'damage.'
