Officials have confirmed a small earthquake hit eastern Tennessee.
According to the Knoxville News Sentinel, the U.S. Geological Survey said the magnitude-2.6 earthquake was reported Sunday morning about three miles south of Lenoir City.
Most earthquakes that inflict serious damage have been rated between 5.5 and 8.9 on the 9-point Richter scale.
USGS officials said the seismic zone extending across Tennessee and northwestern Georgia into northeastern Alabama has been one of the most active for earthquakes in the southeast.
The zone has not been known to have had a large earthquake, though some have caused minor damage.
