Subsidizing
Subsidence is the settling or lowering down of the earth surface due to geological or human-activities. It occurs because of underground material movement such as removal of water, oil, natural gas or mineral resources out of the ground by pumping, fracking or mining processes.
Natural events of subsidence include earthquake, soil compaction, erosion, sinkhole formation, glacial adjustment and loess deposits.
