A magnitude 2.2 earthquake struck almost directly under the Benton MacKaye trail on the Tennessee-North Carolina state line on Tuesday, according to preliminary information from the U.S. Geological Survey.

Initially reported as a magnitude 1.9 quake, information available on Wednesday indicated that the quake that shook the mountains about 1:15 p.m. Tuesday has since been classified slightly stronger.

U.S. Geological Survey information places the temblor just a few hundred feet east of the Unicoi Turnpike where it crosses the state line near the intersecting county lines of Polk and Monroe in Tennessee, and Cherokee in North Carolina.

The quake was estimated at a depth of just less than 2 miles.

A magnitude 2.2 quake is generally felt only by a few people under favorable conditions, according to the USGS.
