List of sinkholes

The Great Blue Hole, a giant submarine sinkhole, located near Ambergris Caye, Belize

The following is a list of sinkholes, blue holes, dolines, cenotes, and pit caves. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks^[1] or suffosion processes.^[2] Sinkholes vary in size from 1 to 600 m (3.3 to 2,000 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide.^[3]
