Officials seek source of sonic booms in New Jersey
TRENTON, N.J. -- Officials are trying to determine the cause of some reported rumblings that shook areas of southern New Jersey.
Residents in several counties reported hearing booms or feeling the ground shake early Wednesday.
But the U.S. Geological Survey didn't report any earthquake activity in New Jersey.
National Weather Service officials say there's "nothing weather-related" that would cause the noise.
Sources tell CBS Philadelphia the booms were generated by an F-35 military plane out of Maryland, which was connected with an offshore training exercise.
Officials say sonic booms have been caused in the past by military planes doing drills along the east coast. It wasn't immediately clear if that's what happened on Wednesday.
No injuries or damage were reported.
