'Earthquake' off Florida's coast was Navy testing

[n2doc]

DAYTONA BEACH, Fla. —What was previously recorded as a 3.7-magnitude earthquake off the coast of Florida was triggered by a man-made explosion to test the seaworthiness of a new U.S. Navy vessel.

Seismographs detected the "earthquake" Saturday afternoon about 168 nautical miles northeast of Daytona Beach Shores.

The U.S. Geological Survey, which monitors earthquake activity worldwide, now lists the event as an experimental explosion. It had previously been listed on the USGS website as an earthquake.

The Daytona Beach News-Journal reports a similar 3.7-magnitude "earthquake" on June 10 off of Ormond-by-the-Sea happened about the same time the Navy reported conducting a shock trial on the USS Jackson for testing. The Navy notified the National Oceanic and Atmospheric Administration's National Marine Fisheries Service that another shock trial would be conducted between July 16 and July 20.
