Coronaca, South Carolina: Flurry of Earthquakes Recorded in a Week

Coronaca, South Carolina, recently experienced a significant increase in seismic activity, as eleven earthquakes were recorded over a span of just 65 hours from August 23 to August 25, 2025. Data from the United States Geological Survey (USGS) indicated that the epicenters of these earthquakes were located a few miles northwest of Coronaca, near the Lake Greenwood area. The initial earthquake struck at approximately 12:15 a.m. on August 23, and the sequence culminated with the last quake occurring around 7 p.m. on August 25.

The recorded earthquakes varied in strength, with magnitudes ranging from 1.7 to 3.0 on the Richter Scale. Among these, two quakes were notably strong, registering at magnitudes of 2.9 and 3.0. These particular earthquakes, which struck on early Saturday morning, caused moderate to strong shaking felt by many residents. The 3.0-magnitude quake even had an impact that was noticeable as far away as Texas, New York, and Rhode Island.

Reports indicate that hundreds of people experienced the seismic sensations during this period. Following this series of earthquakes, local officials advised residents to remain vigilant and prepared for potential future quakes. Authorities emphasized that earthquakes can occur anywhere throughout South Carolina without warning, underlining the importance of household awareness and emergency preparedness.

As of August 29, three additional earthquakes were recorded, bringing the total to 14 quakes in the Coronaca area within the week. The latest seismic activity included a quake registering 1.8 magnitude at 10:20 p.m. on August 29, followed by a 2.0 magnitude quake just over four hours later, and concluding with another quake measuring 1.7 magnitude at 5:04 p.m. on August 30.

Interestingly, this surge in seismic events follows a similar trend observed in October 2024, when the Coronaca region recorded nine earthquakes over a six-day period. For context, South Carolina’s last confirmed earthquake prior to this recent series occurred on August 9, measuring 1.75 in magnitude. In total, the state has recorded 26 earthquakes in 2025 alone.

Historically, the Coronaca area, along with much of South Carolina, has experienced a low frequency of earthquakes, particularly outside the Midlands region where most seismic activity has been noted. The strongest earthquake documented in the state occurred in 1886 in Charleston, registering a catastrophic 7.3 magnitude. In light of the recent uptick in seismic events, officials recommended that residents review their earthquake insurance and secure any items in their homes that might become hazardous during tremors. Despite the increase in earthquake activity, state officials do not anticipate a larger earthquake that could cause significant damage based on current geological data.
