Shortly before 1:00 p.m. on Tuesday, people started calling in to our 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.

This happened around 12:26 p.m. Tuesday afternoon.

The USGS website currently does not have an earthquake recorded.

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.”
