Columbia, SC (WJBF) – An early morning earthquake Monday shook awake residents of Columbia, South Carolina.

It happened shortly after 1:30 a.m.

According to the National Geological Society the tremor registered 3.3 on the Richter Scale.

There are reports that it could be felt as far away as Aiken County.

There were no immediate reports of any damages or injuries.

A seismic analyst monitoring the quake for the USGS Geological Survey’s National Earthquake Information Center in Colorado, called it the latest in a series of shakes in recent months but stronger than usual.

“There’s definitely been a ‘swarm’ here over the past several months. It’s not like a swarm like after a large seismic event but we have had a number of them in recent months,” geophysicist Amy Vaughan with the 24-hour monitoring service told The Associated Press by phone.

She said the quake was a rather shallow one, fairly close to the surface, which made it felt, adding the area has been experiencing other shocks recently.

According to emergency management officials, about 70% of South Carolina earthquakes are located in the Middleton Place-Summerville Seismic Zone, about 12.4 miles (20 kilometers) northwest of Charleston.

In 1886, that historic coastal city was home to the largest recorded earthquake in the history of the southeastern United States, according to seismic officials. The quake, thought to have had a magnitude of at least 7, left dozens of people dead and destroyed hundreds of buildings.

That event was preceded by a series of smaller tremors over several days, although it was not known that the foreshocks were necessarily leading up to something more catastrophic until after the major quake.
