Collapse dolines are a type of karst landform formed when the roof of an underground cavity, such as a cave or void in limestone, collapses, causing the ground above to sink suddenly. This collapse creates a circular or oval depression on the surface, which can range from a few meters to several hundred meters in diameter. The process is often triggered by natural factors like the dissolution of soluble rocks (e.g., limestone, gypsum) by groundwater, but it can also be accelerated by human activities such as mining or construction. Collapse dolines are common in regions with extensive karst systems and can pose significant hazards in populated areas due to the risk of sudden ground subsidence.
