All of the above areas are prone to subsidence. Areas underlain by permafrost may experience thawing and collapse of the ground. Swampy areas can experience the consolidation of the soil due to the weight of the overlying water. Areas underlain by limestone can experience sinkholes due to the dissolution of the rock by water. River deltas can experience subsidence due to the compaction of sediment and the withdrawal of groundwater.
