Florida is a state located in the southeastern region of the United States. Most of the state is a large peninsula with the Gulf of Mexico on its west and the Atlantic Ocean on its east. Much of the state has a humid subtropical climate; southern Florida has a tropical climate. Florida was named by Juan Ponce de León, who landed on the peninsula on 2 April 1513, during Pascua Florida (Spanish for “Flowery Easter,” referring to the Easter season). Florida is the fourth most populous state in the country.
Much of the state of Florida is situated on a peninsula between the Gulf of Mexico, the Atlantic Ocean, and the Straits of Florida. It extends to the northwest into a panhandle, extending along the northern Gulf of Mexico. It is bordered on the north by the states of Georgia and Alabama, and on the west, at the end of the panhandle, by Alabama. It is near several Caribbean countries, particularly the Bahamas and Cuba. Florida’s extensive coastline made it a perceived target during World War II, so the government built airstrips throughout the state; today, approximately 400 airports are still in service. According to the National Drug Intelligence Center, Florida has 131 public airports, and more than 700 private airports, airstrips, heliports, and seaplane bases. Florida is one of the largest states east of the Mississippi River, and only Alaska and Michigan are larger in water area.
The Florida peninsula is a porous plateau of karst limestone sitting atop bedrock. Extended systems of underwater caves, sinkholes and springs are found throughout the state and supply most of the water used by residents. The limestone is topped with sandy soils deposited as ancient beaches over millions of years as global sea levels rose and fell. During the last Ice Age, lower sea levels and a drier climate revealed a much wider peninsula, largely desert. The Everglades, an enormously wide, very slow-flowing river encompasses the southern tip of the peninsula.
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, Florida. There were reports of heavy shaking that knocked plaster from walls and articles from shelves. Similar effects were noted at Daytona Beach, Florida 50 miles (80 km) south. The tremor was felt as far south as Tampa and as far north as Savannah, Georgia. In January 1880, Cuba was the center of two strong earthquakes that sent severe shock waves through the city of Key West, Florida. Another earthquake centered outside Florida was the great Charleston, South Carolina earthquake of 1886. The shock was felt throughout northern Florida, ringing church bells at St. Augustine and severely jolting other towns along that section of Florida’s east coast. Jacksonville residents felt many of the strong aftershocks that occurred in September, October, and November of 1886. As recently as 2006, a magnitude 6.0 earthquake centered about 260 miles (420 km) southwest of Tampa in the Gulf of Mexico sent shock waves through southwest and central Florida. The earthquake was too small to trigger a tsunami and no damage was reported.
