In January 1880, Cuba was the center of two strong earthquakes that sent severe shock waves through the city of Key West, Florida. [8] Another earthquake centered outside Florida was the 1886 Charleston earthquake. The shock was felt throughout northern Florida, ringing church bells at St. Augustine and severely jolting other towns along that ...
The platform's western edge, or Florida Escarpment, is normally defined where water depths at 300 feet (91 m) drop dramatically and in a short distance to 10,000 feet (3,000 m). 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.
Tectonophysics is concerned with movements in the Earth's crust and deformations over scales from meters to thousands of kilometers. [2] These govern processes on local and regional scales and at structural boundaries, such as the destruction of continental crust (e.g. gravitational instability) and oceanic crust (e.g. subduction), convection in the Earth's mantle (availability of melts), the ...
Map of the later North Atlantic region after the closing of the Iapetus Ocean and the Caledonian/Acadian orogenies (Wilson 1966).Animals: Trilobites and graptolites. [1] [2] Euramerica in the Devonian (416 to 359 Ma) with Baltica, Avalonia (Cabot Fault, Newfoundland and Great Glen Fault, Scotland; cited in Wilson 1962) and Laurentia (Other parts: Iberian Massif and Armorican terrane).
But A. Wegener did not have the specialisation to correctly weight the quality of the geophysical data and the paleontologic data, and its conclusions. Wegener's main interest was meteorology, and he wanted to join the Denmark-Greenland expedition scheduled for mid 1912. So he hurried up to present his Continental Drift hypothesis. [2]

Since seismology is based on elastic waves, the speed of waves could help determine density and therefore the behavior of the layers within the Earth. [5] Nomenclature for the behavior of seismic waves was produced based on these findings. P-waves and S-waves were used to describe two types of elastic body waves possible. [6]
That they did is likely because they were found in natural holes in the limestone filled with water, called solution holes, which better preserves them, Ardren said. Human, animal remains uncovered
