On May 10, 2025, a 4.1 magnitude earthquake struck near Greenback, Tennessee, sending tremors across parts of Georgia, North Carolina, and South Carolina. As reports flooded in from Atlanta, Knoxville, Maryville, and even Asheville, NC, many residents asked the same question: “Was that an earthquake just now?”
What Happened in Tennessee Today?
According to the U.S. Geological Survey (USGS), the earthquake occurred just after 9:00 AM and originated from the Eastern Tennessee Seismic Zone (ETSZ). With a shallow depth of around 25 kilometers, the quake was widely felt despite its moderate magnitude.
Areas Affected by the Earthquake
The seismic activity was felt in:
- Knoxville, TN
- Atlanta, GA
- Maryville & Greenback, TN
- Asheville & Charlotte, NC
- Greenville & Spartanburg, SC
While there were no immediate reports of injuries or damage, the earthquake did cause noticeable shaking that startled thousands across the region.
Why Was There an Earthquake in Georgia and Tennessee?
The ETSZ is one of the most active seismic zones in the eastern United States. Unlike California, where large quakes are more common, this region experiences smaller, less frequent events—but they can be felt over a broader area due to denser geological structures beneath the surface.
Aftershock Possibility and Safety
Although aftershocks are expected after moderate quakes, USGS data suggests a low likelihood of dangerous follow-up tremors. Residents should still stay informed and review local emergency procedures.

Conclusion
The May 10, 2025 Tennessee earthquake is a reminder that seismic events can strike unexpectedly—even in areas not known for major quakes. From East Tennessee to North Georgia, residents felt the earth move, sparking renewed conversations around preparedness and awareness.
