Earthquake in Tennessee???

Yes we had one and we felt it!!! This morning at 4 a.m. Tim woke up and then I woke.The house was trembling and even the fans were rocking!! I have heard we have had mild tremors before but this was the first one I ever felt. Tim's first words were asking if that was an earthquake. I was half a sleep and said it might be the wind.Then I realized the fans were not on and they were rocking. That was a very weird feeling. The house vibrated for about another minute before it stopped. Maybe we need to check and make sure we have earthquake insurance!!!
