  • About 5:30 p.m. Thursday, an extraordinarily loud boom rattled central South Carolina, with reports spanning Columbia and at least 40 to 50 miles east.
  • The U.S. Geological Survey placed the event about 3.5 miles northeast of St. Andrews, but by Friday experts had not identified a cause and had already dismissed several online theories.
  • Hundreds of residents described a thunderclap-like blast and rumble that felt like an earthquake, though authorities reported no serious injuries or property damage.
  • Richland County sheriff’s officials said they had not been notified of any cause and had no indication it was a law-enforcement matter, leaving the source of the boom unresolved.
