There was a small-ish tremor from an earthquake, today, where I live--the first one I've ever felt. (It was very mild, with no damage.) It was an interesting experience, though, considering how rare that is in my region. Apparently this one originated from a 5.9 magnitude quake in Virginia. I hope that the damage isn't too severe for those closer to the epicenter.
If you felt the quake, the USGS has a brief questionnaire you can fill out, to help them gather more data.
