It's the reason I'm online at the moment. I was watching TV about a half hour ago, when a vibration occurred, followed by a fairly strong, yet short shake. Everything rattled quite well, and the blinds swayed slightly for awhile after.
So, I ran in here to check the quake site, and lo and behold, we're having some tremors in the area around Anaheim (we're blocks away from DLR). They're happening about every 5 minutes - mainly quick shakes, but we can certainly feel them because we're practically on top of 'em.
Kinda freaky, really. But, thought I'd share. Gotta love California!
