Another rattler hits California

I was home this morning when I heard the bedroom door open on its own and just as I was about to dismiss it as a lost cat burglar or a draught from the open window, I realized that the windows were all shut and that there wasn't anything at home that might interest a burglar! More noises - pictures moving and blinds rattling. I always feel a little dizzy when a quake hits and this time was no different. Just as I was debating whether to step outside, the whole thing settled down. Turned out to be a 6.0 on the Richter scale. I suppose it wore down by the time it got to San Fran from its center in Parkfield, deep Southern Cal beyond LA.
