Greenwood County, South Carolina Experiences Series of Earthquakes

In Greenwood County, South Carolina, a series of earthquakes has been recorded with 14 quakes occurring in just one week, raising local concerns over seismic activity. The United States Geological Survey (USGS) reported two earthquakes on Saturday evening, August 25, 2025, along with several tremors that followed.

The first earthquake on August 25 occurred at 8:28:04 PM, registering a magnitude of 1.3, approximately 8.3 miles northeast of Greenwood. Just one second later, a second quake was recorded at 8:28:05 PM, with a magnitude of 1.7 occurring 11.2 miles north of Greenwood. Given their low magnitudes, these earthquakes typically go unnoticed by residents.

Following these events, three additional earthquakes were reported on Sunday night and Monday. The Sunday tremors included a 1.8 magnitude earthquake at 10:20 PM and a 2.0 magnitude quake confirmed at 2:51 AM on Monday. Another earthquake, registering 1.7 in magnitude, was confirmed around 5:04 PM on Monday. Overall, 14 earthquakes have been noted in the Coronaca area within the past week according to the South Carolina Department of Natural Resources.

Prior to this string of recent seismic activity, Greenwood County noted similar occurrences in late 2024, where nine earthquakes were documented in under a week during October. Earlier seismic events in August 2025, including a 2.2 magnitude quake recorded on August 18 and a 1.7 magnitude quake on August 20, contributed to the growing list of recent earthquakes in the area. Particularly, the moments following midnight on August 25 featured two larger earthquakes, measuring 2.9 and 3.0 in magnitude, occurring only six minutes apart.

Throughout the day on August 25, five additional quakes followed the initial tremors, recording magnitudes of 2.5, 1.9, 2.0, 2.4, 1.8, and 1.7. These earthquakes occurred at varying depths, with some just below the surface and others as deep as five miles underground. In total, South Carolina has recorded 28 confirmed earthquakes in 2025, reflecting a continued pattern of seismic activity.

The last notable earthquake before this wave in Greenwood County was a 1.75 magnitude quake in Myrtle Beach on August 9, 2025. Comparatively, South Carolina had seen 30 confirmed earthquakes in 2024 and 28 in 2023, illustrating fluctuations in seismic events over the recent years.

Considering the frequency of these tremors, officials have urged residents to prepare for potential further seismic activity. Although concerns have been raised, experts do not anticipate a larger-scale quake to follow. History indicates that the most powerful earthquake ever recorded in South Carolina struck Charleston in 1886 with a magnitude of 7.3, resulting in 60 fatalities.

Residents are being advised to review their earthquake insurance policies and ensure their homes are secured against potential damage from seismic activity. Awareness and preparedness are crucial as Greenwood County continues to monitor the recent uptick in earthquakes.
