It woke me up. Not the shaking, the noise from one of the dogs growling, then I heard the window which was not fully latched shut shuttered just a little bit (I actually thought maybe a breeze) and my gadget/toy (quake alarm that sense P waves) was dinging (but it does a lot anyway).
Know a few who live in Napa and the area. Napa had a minor 3.something a week or two ago. One friend & his wife woke ffrom it. Haven't heard from them on this 6.0 yet.
I was actually in the Northridge quake in southern California. The hotel I was in was damaged. Everyone but me evacuated. It was dark, cold outside, and I was comfy so I went back to sleep. Room sure was all messed up.
