I missed it as I was driving and didn&#39;t feel it.<br />Joey, we have them about once every 10-15 years. The last one here was only 6 years ago. It was on a smaller less active fault line and was unnoticeable by a lot of folks. The one today was a part of the New Madrid fault line which in the early 1800s produced a 7.9 magnitude earthquake that permanently changed the course of the Mississippi River and caused it to flow backwards. It also formed Reelfoot Lake in TN.
