The landscapes we see today in Everglades National Park, and in all of south Florida, are the direct result of geologic events of the past and ongoing environmental processes. Over time, sea-level fluctuations resulted in constantly changing conditions during which periods of sediment deposition alternated with periods of erosion. These areas exhibit many karst features including To the south, the middle keys, along with much of Florida Bay, consist of oolitic limestone that is similar to the bedrock that makes up the previously discussed Atlantic Coastal Ridge. However, test results may be affected by the local geology and elevation of the water table, and are not always conclusive. In 1982, the Florida Sinkhole Research Institute was created at the University of Central Florida in Orlando. Because of the age of this publication, some of the information is outdated.

The bedrock underlying the state is honeycombed with cavities of varying size, most of which will not collapse in our lifetimes. Cover-collapse sinkholes occur where sediments overlying the void in the rock suddenly collapse, creating a hole at ground surface. Various private companies have tried developing risk prediction methodologies with very little success. Nosuch database exists within any government agency or private company.

Composed of limestone or carbonate sand and mud, the Florida Keys subprovince consists of long, narrow islands that stretch in an arc from the northernmost keys of Biscayne National Park to the southwesternmost keys of remote Dry Tortugas National Park. Yet further north in the Miami metropolitan area, Key Biscayne is composed of sand, as are the barrier islands that protect much of the entire east coast of Florida. The Floridian peninsula is a porous plateau of karst limestone sitting atop bedrock known as the Florida Platform. I am buying a new home and I want to know if there is a sinkhole disclosure law. It's usually about a four or six-inch deep concrete mat with gravel underneath for drainage. What should I do? In this case, the void in the rock is filled by sediments raveling downward from above.

[8] Another earthquake centered outside Florida was the 1886 Charleston earthquake. Strips of swamps and brackish marshes that are just above sea level characterize this area. High-resolution seismic-reflection profiles were generated using acoustic (sound-wave) instruments. Detailed regional bedrock topography in the Florida Keys was derived from geophysical data that provided the depth of the bedrock surface below present sea level. reappears to the west and to the east of the uplift. States that have a lot of swamp land or wetland territory, as well as those with significant amounts of coastline, simply have too much water in the ground to make most basements feasible . 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.

The sound waves penetrate through the water column and sediments, reflecting the sediment (seafloor) surface and the contact between the sediments and underlying bedrock. The emergent portion of the platform was created during the Eocene to Oligocene as the Gulf Trough filled with silts, clays, and sands.
