Greenwood County, South Carolina Experiences Two Small Earthquakes
Greenwood County, South Carolina, was rattled by two small earthquakes late on August 18 and early August 19, 2025. The U.S. Geological Survey (USGS) reported the first quake occurred at approximately 11:30 p.m., registering a magnitude of 2.2. The epicenter was located approximately 2.4 miles north-northwest of Coronaca at a depth of about 2.5 miles beneath the surface.
The second earthquake struck at 3:08 a.m. on August 19, registering 1.7 on the magnitude scale. Its epicenter was situated around 3.1 miles southeast of Coronaca and occurred more than three miles underground. Both tremors were classified as “micro quakes” under the Modified Mercalli Intensity Scale and have not led to any reported damage or injuries.
Recent Seismic Activity in the Region
These two earthquakes are part of a broader series of seismic activity that has been observed in the Upstate region, with three earthquakes recorded within a week. These incidents mark the 13th and 14th confirmed earthquakes in South Carolina for 2025. Just days before, on August 9, a 1.75-magnitude earthquake was documented near Myrtle Beach.
Since January 18, 2021, the state has experienced a total of 161 earthquakes, indicating a rise in frequency compared to historical averages. South Carolina typically sees between six and ten earthquakes each year. However, the Coronaca area has been particularly active, with nine earthquakes occurring there in just six days in October 2024.
Local Geologists’ Observations
Local geologists have stated that while the recent series of minor earthquakes might seem alarming, they do not necessarily forecast a larger seismic event. The earthquakes in Greenwood County, categorized as micro quakes, produced no significant impacts in the area.
In light of the increased seismic activity, emergency officials advise residents to familiarize themselves with earthquake preparedness measures, such as securing household items and knowing how to respond during a quake. Residents who experienced the recent tremors have been encouraged to report their experiences to the USGS for further data collection.
Historical Context of Earthquakes in South Carolina
South Carolina’s seismic history includes significant events, notably a 7.3-magnitude earthquake that struck Charleston in 1886. This earthquake resulted in substantial casualties and extensive damage. Generally, seismic activity is less common in South Carolina, with the Midlands area and Kershaw County being the primary locations for recorded quakes.
As of now, there have been no reports of injuries or major damages related to these smaller earthquakes or to any previous quakes in the region.
