OMG I never thought I would say this, living in Indiana, but we just had an earthquake! It was a 5.4 and was centered in south eastern Illinois. It only lasted about 5-10 seconds here, but it was enough to wake me up and scare me to death. I was sleeping downstairs on the couch...my first thought was that the house was going to explode from a gas leak or something. Yikes!! We live on the eastern edge of Indiana so this was a strong one! Hope everyone in Illinois is safe!
