Just felt an earthquake a little while ago, but it was different. Two very large very loud bangs and that was it. No rocking, no swaying. Lasted only a couple of seconds but it felt like a truck running into the wall.

I checked the USGS and it was only a 2.9 which I normally wouldn't have noticed but the epicenter is within a mile from here and it was only 6/10ths of a mile deep.
Never been sitting on top of one like that before.
