For the second time in three days, tectonic forces beneath Edgefield, S.C., shook the region in what officials are calling an aftershock from Friday’s earthquake.
About 3:23 p.m. Sunday, a quake with a preliminary magnitude of 3.2 was recorded 12 kilometers west of Edgefield at a depth of 5 kilometers, according the U.S. Geological Survey’s Web site.
Edgefield County Emergency Preparedness Coordinator Mike Casey said the aftershock was in the same general area as Friday’s magnitude-4.1 quake, which was the strongest felt in Georgia in two decades.
The aftershock was felt as far away as Columbia and Thomson, according to responses on the U.S. Geological Survey Web site.
“If I had paid attention to the signs and listened to my dog, I would have known it was coming,” said Casey, whose dog ran for the nearest door moments before the quake happened.
After speaking to firefighters near the center of Sunday’s aftershock, Casey said it appears the quake resulted in less shaking of the ground but had more noise.
He said it’s too early to tell whether more aftershocks will be felt in the coming days.
“That’s when you throw down chicken bones and dice and see how they land,” he said with a laugh.
Friday’s quake was reportedly felt as far away as Athens, Ga.; Atlanta; Spartanburg, S.C.; Columbia; and Charlotte, N.C. Officials from both sides of the Savannah River said Saturday that major structures, including waste tanks at Savannah River Site and reactors at Plant Vogtle, were unharmed.
