Oh, and make sure you fill out USGC's "Did You Feel It?" questionnaire.

"A Strong Earthquake Has Shaken Los Angeles," or so says this jarring single headline on CBS 5. You know anything more? We'll update as soon as we do.

Update 11:45 a.m.: According to Twitter user jamesrocchi, "Earhtquake, fun. 5.6. 29 km from city center, but I felt it fairly well." (And it made him temporarily European! What's a "km"? Oh noes!) More to come.

Also, it's moments like these in SoCal that, inexplicably, make us miss the place. Sadly, it's really one of the few things that brings people together down there. Chin up, other half.

Update 12:48 p.m.: According to Eye On Blogs the quake is actually 5.4. The shaker must've photoshopped its size. Typical.
