Florida is one of the least seismically active US states, with only rare, very small tremors.
The only real protection is a warning the moment the ground moves - which is exactly what the free QuakeMate app gives you, along with tsunami and volcano alerts for Florida.
What the record shows for Florida
Over the last 20 years, USGS has catalogued 0 earthquakes of magnitude 4 or greater within 300 km of Florida - about one every Infinity years. That rate describes how often the ground moves enough to be recorded, not how often damage occurs; most of these are never felt.
No tsunamis are recorded within 300 km of Florida in the NOAA NCEI database. A quiet record is not the same as no exposure - a large enough offshore earthquake can reach coastlines that have never been hit in the historical period.
Sources: USGS earthquake catalog, NOAA tsunami database, and the Smithsonian Global Volcanism Program. Figures update as the catalogs are revised.
