CHARLESTON, S.C. (WCBD) — Shortly before 1:00 p.m. on Tuesday, people started calling in to the WCBD newsroom reporting vibrations from Charleston, Berkeley and Williamsburg Counties.

In Mount Pleasant, people reported hearing a big booming sound. Some on Daniel Island, James Island and Goose Creek said their homes shook.

“My whole house just shook…. anyone else ? Weird and heard loud boom on Folly Beach,” wrote Debbie Wilson Pustorino on Facebook.

“The whole restaurant here at Shem creek just shook! Earthquake?!” Danielle Scott said.

This happened around 12:26 p.m. Tuesday afternoon. The USGS website currently does not have an earthquake recorded.

Beaufort Air Station confirmed that they did have F-18 jets involved in military exercise covering North Carolina, South Carolina and Georgia on Tuesday afternoon. They cannot confirm if it is one of their jets that made the loud boom heard across the Lowcountry.

At 1:37 p.m. the USGS said “We see no detectable EQ in Charleston at the time of reported shaking. The origin of the disturbance is unknown possibly a sonic boom.”

The College of Charleston Earthquake Centers tells News 2, what was recorded on the seismograph was too small to have been an earthquake felt this widespread.

C of C says “Our SC Earthquake Education and Preparedness program says it was a sonic boom, not an earthquake.”
