The term karst, therefore, refers to the terrain, and the term sinkhole is one of the types of drainage features found inthat terrain. There were reports of heavy shaking that knocked plaster from walls and articles from shelves. When the void contains air, it is less competent, and when a large rain event weighs down the overburden, it can collapse into the underlying air-filled void. Over thousands of years, dissolution within pore spaces and along fractures creates increasingly larger voids.

The resulting ooids, or spherical grains of limestone, were pushed by longshore currents into the linear Atlantic Coastal Ridge during the Pleistocene. The Rocky Glades region of Everglades National Park is an area of karst that separates Shark River Slough from Taylor Slough. Over time, sea-level fluctuations resulted in constantly changing conditions during which periods of sediment deposition alternated with periods of erosion. Actual coverage varies according to circumstances and insurance company policy. Note the elevated ridge (in large white rectangle) on which the Marquesas Keys are located. Pine forests are present on the higher ground of the Atlantic Coastal Ridge. Marl and peat soils are like opposites that cannot coexist. In these areas, the limestone bedrock is very close At that time, all FGS sinkhole data files were transferred to the FSRI. The survey refers to the limestone as part of the Biscayne aquifer, and it specifies the limestone as "Miami Limestone." which means that water cannot seep through it to the underlying One of their dutieswas to compile and tabulate this information and convert it to a computer database. While this data may include some true sinkholes, the majority of the incidents have not been field-checked and the cause of subsidence is not verified. Alternatively, when surface sediments ravel downward, instead of collapsing,into cavities a bowl-shaped depression forms at the surface, usually over a considerable period of time.

That is impressive given that much of the state is covered by a sand cap that can be over 100 feet deep in places. However, since these are natural systems, there can be no guarantees that a repaired sinkhole will not cause future problems. Slightly acidic groundwater slowly dissolves cavities and caves in the limestone over a period of many years. Start your own. Bedrock Surface map: Updated map of the bedrock surface shows contours of regional Pleistocene topography from the northern Florida Keys to west of The Quicksands. The clay layer is impervious to water, When an underground cavity enlarges to the point that its ceiling can no longer support the weight of overlying sediments, the earth suddenly collapses into the cavity. It is characterized by its extreme hardness (7.0) andglass-like fracture. Along the 832 miles from Pensacola to Key West, the soil varies.
