Greenwood County, South Carolina Experiences Earthquake Swarm
Greenwood County, South Carolina, is currently experiencing an ongoing earthquake swarm, with a total of 14 earthquakes recorded in the last week alone. The latest quake, which took place on Monday, August 25, 2025, at 5:04 PM, registered a magnitude of 1.7 and was located 1.2 miles northwest of Coronaca.
This recent seismic activity has been marked by an increased frequency of earthquakes, especially noted on Saturday, August 23, when the region experienced a burst of seismic events, including one significant quake measuring 3.0 in magnitude. Early reports indicate that most of the quakes occurred overnight, seven of them between midnight and 4 AM.
On Monday, three earthquakes were observed, which included two smaller ones earlier in the day: one at 1:51 AM with a magnitude of 2.0 and another in the morning measuring 1.8. The earthquakes in this swarm have varied in magnitude, ranging from 1.7 to 3.0.
The seismic activity began on August 19, with the initial quakes recorded at magnitudes of 2.2 and 1.7. A noteworthy quake with a magnitude of 2.0 was documented on Thursday, August 21, near Ware Shoals, approximately 3.1 miles southeast of the recent swarm center. No significant injuries or property damage have been reported despite the noticeable tremors felt by residents in the area.
According to the U.S. Geological Survey (USGS), these earthquakes are centered in Greenwood County, raising awareness among local residents. Experts emphasize the importance of being prepared for seismic events, particularly given the frequency of occurrences. The South Carolina Emergency Management Division has recommended that residents review earthquake preparedness steps, along with their insurance options.
This recent activity represents the most active week for earthquakes in the Greenwood area since a previous swarm in October 2024. USGS research geophysicist Thomas Pratt outlined that typically, significant damage occurs only when earthquakes reach a magnitude of 4.5. Therefore, while the swarming activity appears concerning, the likelihood of larger quakes in the immediate future remains low.
Residents are encouraged to report any shaking sensations they experience through the USGS earthquake reporting service. Awareness and documentation can help experts analyze the patterns of activity and improve preparedness measures for future events.
