Authorities: Rumble Likely a Sonic Boom

WILMINGTON — Local law enforcement officers say a rumble felt across the Wilmington area was likely a sonic boom.

We’ve received phone calls from viewers from around the area, including Wilmington, Bolivia, Southport, Navassa, Winnabow, Leland and Rocky Point, saying they felt the ground shake this morning.

A sonic boom is a shock caused by an aircraft.

There is no information to indicate another cause, and there are no reports of any damage.

R. says she felt something last night and didn’t mention it. We’ve felt this mysterious, massive but quiet unsettling before here a couple times. It’s the “Seneca guns” phenomenon. (USGS: Earthquake Booms, Seneca Guns, and Other Sounds).
