Florida is tied with North Dakota as having the fewest earthquakes of any US state. [7] Because Florida is not located near any tectonic plate boundaries, earthquakes are very rare, but not totally unknown. In January 1879, a shock occurred near St. Augustine. There were reports of heavy shaking that knocked plaster from walls and articles from ...
Aerial image of Wakulla Spring, one of Florida’s large magnitude springs. Wakulla Spring is a karst feature formed by the dissolution of limestone over geologic time.
The upper confining unit is particularly thick in Coastal Georgia and South Florida; downward leakage of water through the upper confining unit in these areas is minimal and the Floridan aquifer system is thickly confined. Low permeability limestone rocks of Paleocene age (e.g. Cedar Keys Formation) form the base of the Floridan aquifer system.
Limestone is a major industrial raw material that is in constant demand. This raw material has been essential in the iron and steel industry since the nineteenth century. [126] Companies have never had a shortage of limestone; however, it has become a concern as the demand continues to increase [127] and it remains in high demand today. [128]

The Miami Rock Ridge of southeastern Florida, the islands of the Lower Florida Keys, and much of the Everglades, are underlain by Miami Oolite. [4] This limestone was formed by deposition when shallow seas covered the area between periods of glaciation. The material consolidated and eroded during later exposure above the ocean surface.

Florida Bay is underlain by a flat oolitic limestone bedrock, the Miami Limestone. The top of the bedrock is about 1 metre (3 ft 3 in) below sea level in the northeast corner of the bay, and slopes to 2 to 3 metres (6 ft 7 in to 9 ft 10 in) below sea level in the southwest.
