My son just called in to say he felt it in Frisco.
You were right on top of it. Nice call.
We got some good jolts and shaking in Oakland. Side to side stuff ... no rough up and down.
KCBS say 4.3 - felt a little bigger than that, but it was right nearby.

If it was that small then it was right under me because it was a decent shake here, close to 10 or so seconds too...
Oh --- now 4.4 shall we start a pool?
Felt it here in Reno. The one man bandits started spilling quarters.
TV 2 news says 4.2 near Lafayette at 840 pm PT
Revision - this will go on for a while ....

Earthquakes are a sure sign of global warming, especially minor ones. Of course a lack of earthquakes is also a sign of global warming. /s
D'int feel it in San Jose, but we were watching _The Fifth Element_ on home theatre with surround sound. Got lost in the 'splosions, maybe.
