TL;DR
A loud sonic boom was heard across the Midlands of South Carolina, confirmed by emergency officials. Experts suggest it was caused by an object traveling faster than sound, but the precise source is still unknown. The event has raised questions about potential military or atmospheric factors.
A sonic boom shook the Midlands of South Carolina Thursday evening, confirmed by emergency officials, with the cause still under investigation. The event prompted widespread reports and questions about its origin, which remains uncertain.
The United States Geological Survey confirmed the occurrence of a sonic boom late Thursday night, with reports from across Columbia and surrounding counties, including Darlington and Chesterfield. Emergency officials verified the noise was a sonic boom, and residents captured videos showing animals reacting and people’s reactions to the loud sound. Experts consulted by WIS explained that such booms typically result from objects moving faster than the speed of sound, such as jets, meteorites, or space debris, though no military activity was reported from local bases. Professor Erin Beutel from the College of Charleston suggested atmospheric conditions, like temperature variations, could cause sound to bounce, making it seem as though the boom originated from multiple locations or different times. Officials from Fort Jackson, Shaw Air Force Base, and McEntire Air National Guard confirmed that the boom did not originate from military operations. The cause remains unconfirmed, and authorities have yet to identify the specific source.
Why It Matters
This event matters because sonic booms can indicate high-speed objects entering or moving through the atmosphere, raising safety and security questions. The lack of military activity suggests the cause might be natural or civilian-related, but the uncertainty leaves residents and officials cautious. Understanding the source is important for public safety and for assessing any potential threats or atmospheric phenomena that could recur.

Background
Sonic booms are typically caused by aircraft exceeding the speed of sound, but recent events have also been linked to meteorites or space debris re-entering the atmosphere. The last significant sonic boom in the region was not recent, making this occurrence unusual. The event follows a pattern of unexplained loud noises reported in various regions, often attributed to atmospheric conditions that can cause sound waves to bounce or amplify. Authorities and experts have been cautious, emphasizing that no military activity was detected, and the event remains under investigation.
“Basically, anytime you have something moving from the atmosphere — if it is moving faster than the air is getting out of the way, all that air gets compressed. When that air gets compressed, it creates a band of compressed air that moves away from that object. It could be a jet, a meteorite or even space junk, but I’m a little wary of space junk because they’re supposed to burn up.”
— Professor Erin Beutel, College of Charleston
“The atmospheric conditions, such as temperature differences between warm and cool air, can cause sound waves to bounce and create the illusion of multiple sources or delayed sounds.”
— Ashwini Karmarker, University of South Carolina
“Based on current information, it appears unlikely that this was due to military operations, but the cause is still being investigated.”
— Venkat Narayanaswamy, North Carolina State University

What’s Next
Authorities and experts will continue investigations, including analyzing atmospheric data and monitoring for any high-speed objects. A formal statement or identification of the source could come in the coming days, and further atmospheric or space activity might be scrutinized to determine the cause.

Key Questions
What caused the sonic boom in South Carolina?
The exact cause is still unknown. Experts suggest it could be a high-speed aircraft, meteorite, space debris, or atmospheric effects, but no definitive source has been confirmed.
Was there any military activity involved?
No, officials from Fort Jackson, Shaw Air Force Base, and McEntire Air National Guard confirmed that the sonic boom did not originate from military operations.
Could atmospheric conditions cause such a loud noise?
Yes, atmospheric phenomena like temperature layers can cause sound waves to bounce or amplify, making the boom seem to originate from multiple locations or times.
Is this likely to happen again?
It is uncertain. If atmospheric conditions are responsible, similar events could recur, especially during temperature inversions or other atmospheric anomalies. If a high-speed object caused it, future occurrences depend on space or aircraft activity.
