    An earthquake sequence consisting of one foreshock, a magnitude 4.6 main shock, and more than 30 aftershocks occurred south of Knoxville during the latter part of 1973. The foreshock, magnitude 3.4, on October 30, was felt over an area of 2,100 square kilometers, with a maximum intensity of V. The main shock cause minor damage (VI) in several towns in eastern Tennessee, Georgia, Kentucky, and North Carolina. Minor cracks in walls at the University of Tennessee Hospital at Knoxville were reported. Minor damage to walls, windows, and chimneys occurred in the Maryville - Alcoa area. The shock disrupted relay contacts at the Alcoa switching station, causing a temporary loss of power. The total felt area, including parts of South Carolina, Virginia, and West Virginia, as well as the region mentioned above, covered about 65,000 square kilometers.
    That one happened in the middle of the night but the boom it caused woke the whole city up.  It sure rattled everyone in my 3rd grade class.  If that's not bad enough, a professor from UT came forth and offered that Knoxville is built on top of a bunch of caverns.

      have been felt here, too, although I don't remember it.  My mom felt a tremor around about that time.  I missed what she felt because I was in my car at the time.  The first one I felt myself is the recent one.  

      BTW, you're just a young 'un.  In 1973 I was a year out of college.  :-)
