Was It an Earthquake? Here's What Happened Off Florida Coast
USGS said the 3.9 seismic event produced ground motions more typical of an explosion than a natural earthquake, and 11 reports came in by July 29.
- On Tuesday, the U.S. Geological Survey recorded a 3.9 magnitude "experimental explosion" 106 miles east-northeast of Flagler Beach, with ground motions appearing more typical of an explosion than a natural earthquake.
- The Navy has conducted "full ship shock trials" in this region in the past, according to the USGS, and News Jax reached out to the service for details on Tuesday's explosion.
- By 7 a.m. Wednesday, the USGS received 11 reports from residents who felt the event, with most concentrated on Florida's East Coast and one reaching as far as Tallahassee.
- Another experimental explosion measuring 3.9 occurred June 16 off Ponce Inlet, though Florida remains among the most geologically stable areas in the United States, according to the USGS.
- Most of Florida faces a 5% chance or lower of experiencing a damaging earthquake in the next 100 years, as the closest fault line runs through the Caribbean Sea north of Puerto Rico and the Dominican Republic.
