Greenwood County, South Carolina Shaken by Series of Small Earthquakes
Early Saturday morning, residents in parts of Greenwood County, South Carolina experienced a swarm of minor earthquakes, creating noticeable tremors in the community. The U.S. Geological Survey (USGS) confirmed that at least seven measurable earthquakes occurred after midnight on Saturday, with magnitudes ranging from 1.8 to 3.0.
The most significant of these seismic events included a magnitude 2.9 quake recorded at 12:17 a.m. and a magnitude 3.0 quake at 12:23 a.m.. Local reports indicated that over 200 residents felt the shaking from the largest quake, with many being awakened by the tremors.
The shallow nature of these earthquakes resulted in loud booms, as the vibrations reached the surface. Although some minor disturbances were reported—such as photos being knocked over—there have been no reported damages associated with these earthquakes, which is typical for events of such low intensity on the Moment Magnitude Scale.
Context of Earthquake Activity in South Carolina
South Carolina is recognized as one of the most seismically active regions on the East Coast, averaging between 10 and 15 earthquakes annually. However, only a select few are strong enough to be felt or to cause damage. The state is home to multiple fault lines, with the Middleton Place-Summerville Seismic Zone being the most active area for seismic activity.
Most seismic activity occurs within the North American plate, limiting the impact of such events. However, historical earthquakes, such as the devastating 1886 Charleston earthquake—estimated to be between magnitude 7.0 and 7.3—resulted in significant destruction and loss of life in the region. Emergency management experts have warned that if a major earthquake were to occur today, it could have severe consequences due to the state’s growing population and aging infrastructure.
Growing Seismic Activity
The recent earthquakes add to a string of seismic activities recorded in the area, bringing the total to ten earthquakes over the last week alone. Prior to Saturday’s events, smaller earthquakes with magnitudes of 2.2, 1.7, and 2.0 were also noted. The earthquakes were primarily concentrated north of Coronaca, approximately six miles from Greenwood, near the Saluda River and close to the Laurens County border.
Residents have expressed concerns about the frequency of these events as the community continues to experience tremors without adverse outcomes. While seismologists continue to monitor the situation, no significant damages or injuries related to these recent earthquakes have been reported.
