The State of South Carolina was rocked by an earthquake shortly after 10:20 p.m. on Friday night – a seismic event felt from the state capital in Columbia, S.C. all the way up to Fountain Inn, Simpsonville and Spartanburg in the Palmetto Upstate (and all the way down to Charleston in the South Carolina Lowcountry).

In Columbia, the tremors lasted only a few seconds … and were hardly earth-shattering.  In fact many who took to social media in the immediate aftermath of the rumbling weren’t exactly sure what had happened.

According to the U.S. Geological Survey, the quake registered 4.4 on the Richter Scale – with its epicenter located 12 kilometers west-northwest of Edgefield, S.C.

That’s awfully close to the U.S. Department of Energy’s Savannah River Site …

South Carolina lies on a fault line, and according to earthquake expert Richard Cote is “home to one of the most active earthquake-producing regions in North America.”

The last major quake to strike the region took place on August 31, 1886 in Charleston, S.C. – killing more than 100 people, destroying more than 2,000 buildings and causing between $5-6 million in damage (roughly $150 million in today’s money).
