The noise was heard at around 11 a.m. ET on Tuesday, shaking windows, surprised residents told the station.
The nearby Columbus Air Force Base Office of Public Affairs said they don’t have a reason to believe the base was behind the boom. An investigation was launched, a spokesperson told the news outlet, which had suggested that a plane may have produced a sonic boom.
WCBI noted that the base rarely permits supersonic travel after it “caused lots of damage on the ground in the 1960s and 1970s.”
The Tennessee Valley Authority, meanwhile, said there were no problems at the Caledonia Combined Cycle Plant.
Several local officials – including Caledonia Mayor Mitch Wiggins and Lowndes County Emergency Management Agency Director Cindy Lawrence – said they got no reports of the boom or damage.
Wiggins, however, said he saw reports online from local residents in Caledonia, but he added that no 911 or emergency calls went out.
The U.S. Geological Survey said there was no earthquake in the area.
A recent boom was reported on Nov. 20 at around 9 p.m. in Lochbuie, Colorado.
“[O]ur officers were notified of a suspicious sound, described as a ‘loud boom’ that shook multiple houses, coming from the northwest side of Lochbuie. At this time, the origin of the sound is unknown,” Lochbuie Police Department stated on Facebook.
There were also booms recorded in places like New Zealand, Detroit, and New Jersey.
“Reports of a loud sound coming from various parts of the county,” St. Clair County Emergency Management Agency said on Twitter after the Nov. 15 “'Bama Boom.” “We will post information as soon as it becomes available.”
