Florida is among the most geologically stable areas in the United States. “We have had earthquakes in Florida — and we could have one today — but it’s not as likely as other places,” said Doug Smith, professor of geology and longtime director of the University of Florida’s seismic network in 2000. He explained earthquakes tend to occur in regions near the boundaries of underground plates or at weaknesses in the plates themselves. The closest fault line to Florida runs through the Caribbean Sea, just north of Puerto Rico and the Dominican Republic and south of Cuba toward Guatemala. Florida does not include any plate boundaries, and the plate the state occupies is very stable, he said, adding there are no recent volcanoes and no none active faults in the state.
