This lays in Concord, northern Bay area and Concord had a 4.5 earth quake last night around 10:30 pacific time. I did not feel it, but June's son and his fiance was sleeping, and they have a Shepard and it woke them up about that time, and it could be felt as far down as San Jose I have read. But who knows if the earth quake had anything to do with it.
June and I was sleeping too, and did not notice anything. June's daughter was sitting in her bed doing something at that time and did not feel anything either. The epicenter was said to have been 9 miles under the surface.
