Chances are few felt a small earthquake Thursday morning in Monroe County.
The magnitude 1.8 earthquake was reported about five miles south of Sweetwater at 8:40 a.m., according to U.S. Geological Survey.
No damage has been reported.
The earthquake had a depth of 15.1 kilometers, or about 9.3 miles. People very rarely feel quakes that small.
The Eastern Tennessee seismic zone, which extends across Tennessee and northwestern Georgia into northeastern Alabama, is one of the most active earthquake areas in the southeast. However, most of those are small and rarely cause damage.
The largest ever recorded in the area was a magnitude 4.6 on April 29, 2003, near Fort Payne, Alabama.
