Tuesday June 19th is the start of one of the states largest emergency response drills. While the main focus of the simulation is the New Madrid Seismic Zone near Memphis, a real earthquake was being felt 170 miles east near the small town of Spencer (about 50 miles North of Chattanooga).
Although the quake was not widely felt, it is a constant reminder that earthquakes can occur at anytime and anyplace and they don't always strike along active fault lines. Tuesdays quake measured 3.3 and occurred at 1:16 PM local time.
If you think that earthquakes never happen in this area, you may be interested in this map which shows all earthquakes in the area (since 1970) with a magnitude of 2.5 or greater.
