UPDATE: The U.S. Geological Survey and TVA confirm that there were two earthquakes this morning near Watts Bar Nuclear Plant in Meigs County.
TVA and USGS officials say a second magnitude 3.3 earthquake – an aftershock of the first one that shook Meigs County around 4:14 a.m. – struck a few minutes afterward and was a little nearer the nuclear plant.
The second quake was about 6.8 kilometers deep and was about a mile west of the first, officials report.
TVA spokesman Jim Hopson said this morning that the federal utilities’ facilities up and down the Tennessee River reported no damage and officials are continuing to run through checklists to make sure nothing was overlooked.
