‘Earthquake’ Off Florida Coast Was Actually Explosion Set Off By Navy

Saturday's undersea "earthquake" off northeast Florida actually was the Navy doing an experimental explosion, said John Bellini with the U.S. Geological Survey in Colorado.


The shock from the 10,000-pound explosive caused a minor earth tremor, registering 3.7 magnitude on a Geological Survey seismometer at Disney World, Orlando.

It was detected at 4 p.m. Saturday about 156 miles east northeast of Daytona Beach.

Later, the Navy confirmed it was detonating underwater explosives to test a new ship's ability to withstand shock. Based on the information, the Geological Survey reclassified the quake as an experimental explosion, Bellini said.

The explosion was the latest in a series of tests in the ocean that started June 10, said Dale Eng, spokesman for the Naval Sea Systems Command, Washington, D.C. The ship being tested is the USS Jackson, based out of Mayport Naval Air Station near Jacksonville.

So far, said federal officials, there are no signs the explosions harmed sealife.

Before the latest explosion, the Navy had notified the National Marine Fisheries Service the explosion could occur anytime from July 16 and 20, weather permitting.

Real earthquakes are rare in Florida. The last recorded on the Treasure Coast was in the 1870s. Dr. James Henshall, of Kentucky, felt rumblings underneath him at night while camping with others camping along the St. Sebastian River in northern Indian River County. Henshall's book, "Camping and Cruising in Florida," said, "I learned afterward that it was quite severe in some portions of the state. At the Cape Canaveral lighthouse "it threw oil out of a lamp on the reflector ... and shook the solid brick tower of the Jupiter lighthouse to its base."

The possibility is remote for an effect of earthquakes: tsunamis. Along the Treasure Coast, such waves could come either from an earthquake zone off Puerto Rico or from across the ocean from the area near Portugal, National Weather Service forecaster Scott Spratt said.

Indian River County is the only county on the Treasure Coast to be designated as "TsunamiReady" by the National Weather Service. That means the county has contingency plans for handling a tsunami and has posted signs along the beaches.

SACRAMENTO, Calif. — As many as 380 Americans on the Diamond Princess cruise ship docked in Japan – which has nearly 300 passengers who have tested positive for the deadly coronavirus, now known as COVID-19 – will be extracted Sunday from Yokohama and flown to Travis Air Force Base near Fairfield and a Texas base for further quarantine.

After whiffing on its recruiting goal in 2018, the Army has been trying new approaches to bring in the soldiers it needs to reach its goal of 500,000 in active-duty service by the end of the 2020s.

The 6,500-soldier shortfall the service reported in September 2018 was its first recruiting miss since 2005 and came despite it putting $200 million into bonuses and issuing extra waivers for health issues or bad conduct.

Within a few months of that disappointment, the Army announced it was seeking soldiers for an esports team that would, it said, "build awareness of skills that can be used as professional soldiers and use [its] gaming knowledge to be more relatable to youth."

WASHINGTON — The Pentagon is requesting about as much money for overseas operations in the coming fiscal year as in this one, but there is at least one noteworthy new twist: the first-ever Space Force request for war funds.

Officials say the $77 million request is needed by Oct. 1 not for space warfare but to enable military personnel to keep operating and protecting key satellites.

NEW YORK (Reuters) - U.S. prosecutors on Thursday accused Huawei of stealing trade secrets and helping Iran track protesters in its latest indictment against the Chinese company, escalating the U.S. battle with the world's largest telecommunications equipment maker.

In the indictment, which supersedes one unsealed last year in federal court in Brooklyn, New York, Huawei Technologies Co was charged with conspiring to steal trade secrets from six U.S. technology companies and to violate a racketeering law typically used to combat organized crime.
