Downgraded to a 5.4; 34 aftershocks recorded so far (I've only felt one). It was a sharp shock here, followed by some seconds of shaking...lost the cover of a light panel near me, apparently one of the other buildings took some damage. We had 15 minutes of faffing around and checking the website (
http://quake.wr.usgs.gov/recenteqs/Maps/118-34.htm), then the second floor was instructed to evacuate. I couldn't find anybody who actually knew anything, but I cleared out, too, and got a half row of knitting done in the parking lot before they told us to go back in.
