Tennessee shaking: 4.4 quake

The U.S. Geological Survey says a magnitude 4.4 earthquake struck eastern Tennessee and could be felt in Atlanta.

The light earthquake occurred Wednesday around 4:14 a.m. about 7 miles (11 kilometers) northeast of Decatur. About 13 minutes later, a 3.3 magnitude aftershock then struck.

There are no reports of injuries. But lots of rattled nerves.

Maybe MORE nerves will be rattled when contemplating this: The quake appeared to occur along the Eastern Tennessee Seismic Zone, a southwest-to-northeast belt extending from Alabama to far southwest Virginia that is the second-most active quake zone in the central and eastern U.S. behind the more notorious New Madrid zone.
