Magnitude 4.1 Quake Rattles SC

Magnitude 4.1 Quake Rattles SC

People in the Midlands felt or heard the ground shake slightly Friday night from a magnitude 4.1 earthquake that was centered about 7 miles west-northwest of Edgefield.

The U.S. Geological Survey reports that the quake was about 60 miles west-southwest of Columbia and 21 miles north-northwest of North Augusta.

It occurred at 10:23 p.m.

The geographical location was 33.813N latitude and 82.063W longitude, at a depth of 4.8 kilometers or roughly 3 miles.

There are no reports of significant damage, but residents of South and North Carolina, Georgia, Tennessee and Virginia say they felt the tremor.

USGS Geophysicist Dale Grant says even though the quake was light, it was felt so widely because it was relatively shallow and the geology of this region transmits tremors easier than along the West Coast.

The U.S. Army Corps of Engineers will be checking dams along the Savannah River for any signs of damage.

Grant says there have been 4 quakes of similar magnitude over the past 40 years in the vicinity of Friday night's earthquake.

South Carolina normally experiences 15 to 20 quakes each year.

The state Department of Natural Resources says none over the past year have exceeded 2.5 magnitude.

Friday night's quake was north of the Aiken-Augusta area, still battling power outages and downed trees as one of the regions hit hardest by this week's winter ice storm.
