http://www.showme.net/~fkeller/quake/ I found this recently and if you click on one of the maps, it shows where all the recent earthquakes have been happenin in the Midwest. Look at that area along the Mississippi in Missouri and Arkansas. Not a good place to live. Also, it appears that the knoxville area likes to shake, too.
yep, my wife thinks she felt one last fall here in Memphis. I thought she was full of it until the news reported an EQ in Arkansas and that it could be felt in Memphis Ryan
