UPDATE (10/30/16 12:30 PM) -- an area near Cherokee, North Carolina, experienced four weak quakes in the early hours of Sunday morning.

Three of those earthquakes were a magnitude of 2.2. The fourth was slightly weaker, measuring just 2.1 on the Richter scale because it happened further below the Earth's surface.

This is the third report of earthquakes in this area in the past week.

PREVIOUS -- For the second time in a week, a weak earthquake has rocked part of East Tennessee.

The U.S. Geological Survey recorded a 2.6 magnitude earthquake shortly after midnight Sunday on the boundary of Monroe and Loudon County northwest of Tellico Lake.

Viewers called in shortly after the quake, saying they felt shaking and heard what sounded like a loud explosion. The USGS says noises like these commonly come with these small earthquakes.

This is the second earthquake recorded in East Tennessee in the last week. On October 25, a similar magnitude 2.9 earthquake shook the Louisville area. The USGS says this type of seismic activity is not uncommon, as thousands of small earthquakes happen across the country on any given month.
