UPDATE: Shaking in Connecticut Caused by Sonic Boom, USGS Says

The United States Geological Survey says shaking reported on the Connecticut Shoreline Thursday afternoon was caused by a sonic boom in New Jersey.

The USGS say the sonic boom occurred at 1:24 p.m. about 2 miles northeast of Hammonton, N.J.

The Naval Test Wing Atlantic, based in Patuxent River, Md., was conducting routine flight testing in the Atlantic Test Ranges this afternoon “that included activities which may have resulted in sonic booms,” the Navy said in a statement, according to WTNH News 8 reports.

Some Connecticut residents living along the Shoreline including in Madison, Branford, Killingworth and West Haven reported that they felt the shaking too. The shaking could also be felt in Naugatuck, Trumbull and Fairfield, News 8 reports.

The town of Madison on its official Twitter account wrote this afternoon:

Town of Madison, CT ‏@Madison911

Callers from Ft. Path Rd. reporting that they felt shaking at around 2:30 pm. Possibly related to reported earthquake in Southern NJ?

A Killingworth resident contacted NBC Connecticut to report that they felt nine “significant tremors” and a West Haven reported two tremors also.

New Jersey residents reported shaking Thursday afternoon and the United States Geological Survey is investigating, according to Patch’s Tom Davis.

John Bellini, geophysicist with the United States Geological Survey, initially said it could have also been an earthquake or a sonic boom from a jet but “I don’t know.”

He said the USGS was investigating to determine what happened.

“We’ve gotten reports all the way from Long Island all the way down to southern New Jersey,” he said.
