Coronaca, South Carolina
A magnitude 2.2 earthquake struck Coronaca, South Carolina, at 4:19 p.m. on Friday. The tremor’s depth was recorded at 3.5 miles. Located just six miles from Greenwood, the epicenter of the quake was situated northwest of Coronaca, near the intersection of Old Laurens and Blackwell roads. As of 9:30 a.m. on Saturday, fewer than ten individuals reported feeling the earthquake.
This incident is part of a larger trend, as the area has experienced approximately 20 earthquakes over the past two months. Most of these events have occurred in the northwestern section of Lake Greenwood and the Saluda River region. Notably, an earthquake swarm took place from Saturday to Monday, resulting in a total of 11 earthquakes with magnitudes fluctuating from 1.7 to 3.0. The first of these earthquakes occurred around 12:15 a.m. on August 23, with the last occurring about 7 p.m. on August 25. Two of these earthquakes, with magnitudes of 2.9 and 3.0, generated moderate to strong shaking, and the 3.0-magnitude earthquake was felt as far away as Texas, New York, and Rhode Island.
During the 65-hour swarm period, hundreds of individuals reported experiencing the tremors. The South Carolina Emergency Management Division has issued urgent warnings for residents to prepare for potential earthquakes. Despite the frequency of these seismic activities, there have been no injuries or significant damage reported thus far.
Experts consider the recent earthquakes to be the most active in the Coronaca and Greenwood area since an earlier swarm that occurred in October 2024. Although earthquakes are not uncommon in the Eastern United States, the unusual frequency of events in this specific area has raised concerns. However, experts remain cautious about interpreting these swarms as foreshocks for a larger earthquake.
South Carolina officials encourage residents to develop disaster plans to ensure preparedness for potential seismic activity. According to research by USGS geophysicists, damage from earthquakes typically occurs once they reach a magnitude of 4.5, making the recent tremors less likely to result in severe harm.
