Oops, Florida Earthquake Saturday Was Really Navy Test

Remember all that social media buzz over the weekend about an earthquake off the coast of Daytona Beach? Never mind.

It appears the “earthquake” detected on Saturday by seismographs as far away as Venezuela and across the United States and Caribbean was triggered by a man-made explosion designed to test the seaworthiness of a new U.S. Navy vessel.

A similar 3.7 magnitude “earthquake” was reported by the U.S. Geological Survey on June 10, 156 nautical miles east-northeast of Ormond-by-the-Sea. That was the same day the Navy reported conducting a shock trial on the USS Jackson, headquartered at Mayport for testing. Shock trials test a ship’s ability to withstand the effects of underwater explosions and remain seaworthy.

On Saturday, the Geological Survey again reported a 3.7 magnitude “earthquake” around 4 p.m. about 168 nautical miles east-northeast of Daytona Beach Shores.
