A 4.1-magnitude earthquake struck East Tennessee on the morning of May 10, shaking homes from Knoxville to as far away as Atlanta. The U.S. Geological Survey (USGS) reported the quake hit at 9:04 a.m. ET, with the epicenter located near Greenback, about 30 miles southwest of Knoxville, at a depth of 15 miles.

Though no injuries or major damage were reported, the tremor startled residents across the region.

More than 23,000 people submitted reports to USGS within the first hour. The Knoxville Fire and Police departments confirmed no emergency calls related to the quake, and TVA facilities were unharmed. Precautionary inspections were also conducted at several dams.

The event occurred within the East Tennessee Seismic Zone, a region known for frequent but typically low-intensity earthquakes.

While considered small, this was the strongest quake in the area since 2018 and served as a reminder of the region’s underlying seismic activity.
