Sinkholes are typically caused when a deposit of earth comprised of a soluble rock, such as limestone, salt or gypsum, is exposed to water and dissolves. When limestone dissolved in rainwater, lower down the bedrock and groundwater flowing in the passage, then washes away the soil. Privacy Policy . The ground continues to disintegrate from beneath. Step #3: Fence or Rope Off the Area. "Third body pulled from giant sinkhole." It may all start as precipitation, but through infiltration and seepage, water soaks into the ground in vast amounts. Sinkholes are most common in what geologists call, "karst terrain." The last flooding scenario happens when an overflowing river is connected to a sinkhole via underground streams and conduits. Over time, surface drainage, erosion, and deposition of sinkhole into a shallower bowl-shaped depression.
