An earthquake jostled Blount County late Tuesday night, U.S. Geological Survey scientists confirmed.

At approximately 11:06 p.m., a 2.4-magnitude earthquake struck Rockford, with its center at Williams Mill Road. No injuries or damages were reported to the city of Rockford as of 12:40 p.m. Wednesday.

The earthquake was the 63rd in East Tennessee so far in 2019 and the third over the past seven days.

Other earthquakes this week shook Monroe and Bradley counties.

These counties along with Blount are part of the East Tennessee Seismic Zone, one of the most active seismic areas in the South.

Earthquakes in East Tennessee are mostly unharmful, John Bellini, a geophysicist for USGS, told The Daily Times.

“Almost nobody ever feels below a 2.0-magnitude earthquake,” Bellini said. “Most people can feel down into the low 2.0-range if they’re in a quiet situation.”

Small earthquakes occur almost everywhere, Bellini added. A total of 134 earthquakes with a magnitude 2.0 or greater occurred nationally last week.

Bellini said there was little reason for concern despite the fact earthquakes are common in the area.

“The Earth doesn’t live on a human time scale,” he said, “... precautions are not any different from weathering a bad winter storm.“
