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 ...
The Florida peninsula is located on the eastern side of the platform, where in places it lies only 3 to 4 miles (4.8 to 6.4 km) from the platform's edge. On the gulf side the platform ends over 100 miles (160 km) to the west of the modern shoreline, where a massive cliff rises over 6,000 feet (1,800 m) from the 10,600 feet (3,200 m) depth of ...
At 345 feet (105 m) above mean sea level, Britton Hill in northern Walton County is the highest point in Florida and the lowest known highpoint of any U.S. state. [3] Much of the state south of Orlando is low-lying and fairly level; however, some places, such as Clearwater, feature vistas that rise 50 to 100 feet (15 to 30 m) above the water.
The Hawthorn Group includes several geologic formations found in southeastern South Carolina, the coastal plain of Georgia, and much of the Florida Peninsula.The Hawthorn Group extends from southeastern South Carolina through the coastal plain of Georgia and the Florida Peninsula to south Florida.
The first comprehensive study of Florida's springs was published in 1947. The next update was released 30 years later in the Florida Geological Survey Bulletin No. 31, Revised, "Springs of Florida". [6] In the 1977 Rosenau survey, there were sixteen offshore (under water) springs identified. All but two were situated on the Gulf coast.
Location of the Peace River Formation in Florida. Fossil (Gavialosuchus americanus) from the Peace River Formation, Florida. The Peace River Formation is a Late Oligocene to Early Miocene geologic formation in the west-central Florida peninsula.
Let us sing an ode to ooids, the tiny, roly-poly balls of broken shells that formed South Florida’s oolite limestone bedrock. South Florida geology 101: Lessons in the rock about future risks ...
In the first regional map depicting transmissivity variation across the aquifer, Miller (1986) showed that transmissivity values exceed 250,000 ft 2 /d (23,000 m 2 /d) where the aquifer system is either unconfined or thinly confined. In areas where the aquifer is thickly confined, Miller (1986) indicated lower transmissivity was related ...
