Two earthquakes struck Wednesday morning in eastern Tennessee, rattling people awake across several Southeastern states.
Residents in Tennessee and Georgia got a big surprise Wednesday morning: the rumblings of an earthquake.
A magnitude 4.4 earthquake was recorded by the U.S. Geological Survey at around 4:14 a.m. ET, with its epicenter near Decatur, Tenn., which is roughly more than 150 miles from Nashville.
An aftershock was felt about 13 minutes later with a magnitude of 3.3, said the USGS.
According to Atlanta TV station WXIA, the earthquake was felt as far as northern Georgia.
Some light and weak shaking was felt as far as Nashville and Murfreesboro to the west and even north into Kentucky.
This morning's M4.4 earthquake near Decatur is the second strongest on record in East TN, according to the USGS. The strongest was a M4.7 near Maryville in 1973. #earthquake— NWS Morristown (@NWSMorristown) December 12, 2018
According to the USGS, the Eastern Tennessee seismic zone is one of the most active earthquake areas in the Southeast. The zone extends across Tennessee and northwestern Georgia into northeastern Alabama.
Confused residents in the region took to social media, including Twitter, to confirm the earthquake. The hashtag #earthquake is among the top trending searches on Twitter as of Wednesday morning.
There have been no reports of serious damage or injuries.
The National Weather Service in Morristown, Tenn., reported on Twitter the quake was the second strongest on record in East Tennessee. The strongest was a 4.7 magnitude earthquake that struck the region in 1973.
The area is part of the Eastern Tennessee Seismic Zone, stretching from northeastern Alabama to southwestern Virginia. It's the second-most active seismic zone in the central and eastern US, behind the New Madrid zone in the Mississippi River region, according to the Seismological Society of America.
Wednesday's 4.4-magnitude quake is the strongest of 799 recorded in the central US in the last six months, according to a list compiled by the University of Memphis' Center for Earthquake Research and Information.
