Seven Earthquakes Shake Greenwood County South Carolina Overnight

Greenwood County, South Carolina, experienced a swarm of at least seven to eight small earthquakes early Saturday morning, with magnitudes ranging from 1.5 to 3.0. The strongest quakes, measuring 2.9 and 3.0 magnitude, occurred near Coronaca and the Saluda River within minutes of each other, shaking homes and causing unsecured objects to move but no reported major damage. Residents reported feeling the tremors and hearing loud booms, typical of shallow earthquakes, which are common in South Carolina due to its location near multiple fault lines in the Middleton Place-Summerville Seismic Zone. Despite the cluster being unusual, seismic experts note that South Carolina typically experiences 10 to 15 earthquakes annually, with occasional larger historic events like the 1886 Charleston earthquake. Emergency officials are monitoring the situation and advising residents to check for structural damage and prepare emergency kits, although no evacuations or road closures have been issued. The activity highlights the state's position as one of the East Coast's most seismically active regions.
