Greenwood County, South Carolina Experiencing Unprecedented Earthquake Activity
Greenwood County is currently the epicenter of a significant surge in seismic activity, as the area recorded its 10th consecutive earthquake early Tuesday morning. The latest tremor, measured at a magnitude of 1.5, struck at 7:13 a.m., just below the surface of the ground. The U.S. Geological Survey (USGS) confirmed this event, highlighting an ongoing pattern of shaking that has gripped this region since October 10.
Timeline of Earthquakes
This recent earthquake is part of a remarkable series of seismic events in Greenwood County. On Sunday alone, eight earthquakes were reported, with seven of those occurring in the community of Coronaca. In total, 26 earthquakes have now been confirmed in South Carolina this year, following 28 incidents last year. These statistics are markedly higher than the historical average of six to ten quakes per year in the state, which has prompted concern among residents and officials alike.
Implications and Preparedness
This unusual seismic activity coincides with Earthquake Preparedness Week, as declared by South Carolina’s Emergency Management Division. Officials are using this opportunity to encourage residents to prepare for potential earthquakes. Kim Stenson, the state’s Emergency Management Division director, emphasized the importance of reviewing insurance policies for earthquake coverage and securing loose items in homes that could pose hazards during tremors.
Understanding the Recent Activity
While Greenwood County is now experiencing a dramatic uptick in seismic events, it is important to note that historically, most earthquakes in South Carolina have occurred in the Midlands region, particularly from Kershaw County down. Since June 2022, Kershaw County has recorded 64 earthquakes, including two significant quakes in June 2022, registering magnitudes of 3.5 and 3.6. The strongest quake recorded in South Carolina’s history remains a devastating 7.3 magnitude event in Charleston back in 1886.
Science Behind the Shaking
Despite this surge of activity, experts have not determined a single cause for the quake patterns, although some theories suggest a link to the Wateree River and its fluctuating water levels over the past two years. The South Carolina Department of Natural Resources (DNR) mentioned that many smaller tremors could have gone unnoticed, with as many as 200 possibly unrecorded during recent years. For reference, at least 130 earthquakes have been detected statewide since the beginning of 2022, predominantly centered around Columbia.
No Major Damage Reported
So far, Tuesday’s tremor and others in this recent spate have not resulted in any reported injuries or significant damage. The Earthquake Preparedness Week initiative urges residents to take precautionary measures, emphasizing personal safety protocols such as “drop, cover, and hold on” during tremors. Experts underscore that earthquakes with a magnitude of less than 5.5 are unlikely to cause significant destruction.
What Residents Should Do
Residents in Greenwood County and surrounding areas who felt Tuesday’s earthquake are encouraged to report their experiences to the USGS. State geology experts are closely monitoring these events, but they are cautious not to alarm the public unnecessarily. “While the frequency of these minor earthquakes may raise concerns, we do not currently anticipate a major earthquake in South Carolina at this time,” said Stenson.
As this situation continues to develop, officials will provide updates and further guidance to residents. With the increased seismic activity, now is the time for South Carolinians to remain vigilant and prepared.
