Oklahoma had it biggest earthquake ever. A 5.6. I know that might not sound like much but for Oklahoma it was a "big one". Our mobile home really shook and the sound was like a big truck or train was right on top of us. We didn't know what it was and all my area got was the after shock. There was some damage to some homes and roads. It is just so rare here. We didn't have any damage, but my friend in Oklahoma City had some minor damage.
