Geological sinkhole.
The GIS-based intersection of sinkhole location and geo-thematic information allowed us to explore the relation between ground collapses and geological setting, the latter being declined by some selected parameters, such as thickness, depth to top and bottom of different units and other synthetic information (e.g. ratio of thickness to the depth of …
Collapse sinkholes are found in groundwater recharge zones throughout the world. They cause substantial loss of property each year, and occasional fatalities. In such settings, the formation of these features occurs through the downward migration of regolith into karst voids. The presence of a void in the bedrock, and sufficient seepage pressure …The U.S. Geological Survey (USGS) says sinkholes commonly occur when the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by ...Science Publications News FAQ It is a frightening thought to imagine the ground below your feet or house suddenly collapsing and forming a big hole in the ground. Sinkholes rarely happen, but when they strike, tragedy can occur. Sinkholes happen when the ground below the land surface cannot support the land surface.Sinkholes of Hernando County, Florida, 1948 to 2007 This map was created by FCIT and represents reported sinkhole events in Hernando County based on data gathered by the Florida Geological Survey (FGS) and the Florida Sinkhole Research Institute (FSRI) between 1948 and 2007. These are called solution sinkholes. These rocks dissolve when attacked by rainfall or groundwater that is acidic. Solution sinkholes have sides that vary from gentle slopes to almost vertical, while their shapes include saucer-like hollows, cones, cylindrical potholes and shafts. Streams or rivers may enter a sinkhole and disappear underground.

Sinkholes are naturally occurring geologic hazards that can cause voids/cavities to develop in the subsurface in regions underlain by Limestone/Dolomite geology. Once sinkholes develop, they can cause significant damage to property, pose safety threats, and are typically costly to repair.Most sinkholes occur in places where water can dissolve the rock below the surface, for example where the bedrock is limestone, salt, or gypsum. They can collapse very quickly, or slump slowly over time. Many sinkholes occur naturally, but human activities can also cause them.
