A preliminary 3.3 magnitude jolted many residents of the northeast of South Carolina’s capital city early Monday.
According to reports, no damages or injuries in the relatively rare East Coast earthquake.
Sources said the pre-dawn earthquake lasted only seconds, but many people took to social media to describe being shaken from sleep when the quake hit shortly after 1:30 a.m. A seismic analyst monitoring the earthquake 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.
Geophysicist Amy Vaughan revealed the 3.3 magnitude is an early assessment and could change, adding the quake occurred about 1.9 miles (3.1 kilometers) below the earth’s surface near the community of Elgin. The epicenter was about 21 miles (3 kilometers) northeast of downtown Columbia, the capital city.
The residents who felt the earthquake said they felt like it was shaking for several seconds, and some even described what sounded like a heavy truck moving nearby.
