The range of quakes in this sequence varied from magnitudes of 1.7 to 3.0, with experts from the US Geological Survey noting that this week represented the most active period in the area since a similar swarm in October 2024.
Residents in the Greenwood County region have reported feeling shaking from these earthquakes, and the USGS has invited those who experienced the trembling to share their accounts. Research geophysicist Thomas Pratt commented on the nature of earthquakes in the Eastern U.S., indicating that while they are not uncommon, the frequency of occurrences in such a brief timeframe is unusual.
Although experts remain uncertain regarding the cause of this earthquake swarm and whether the tremors are precursors to a larger seismic event, historical patterns indicate that some swarms have preceded more significant earthquakes. However, current assessments suggest that the likelihood of the ongoing swarm triggering a substantial quake is low.
In summary, Greenwood County is currently experiencing heightened geological activity with a notable series of earthquakes. Local officials are emphasizing the importance of preparedness as they monitor the situation closely.
