quake, East Bay, Hayward fault


We had a minor but vivid little earthquake just before midnight -- about three seconds of shaking and a roar like thunder. I automatically start timing the length of the shaking: Mississippi 1, Mississippi 2, just as I used to time the gap between lightning and thunder back home.

It was centered on Fairmont Drive, a couple miles from here, so it was quite noticeable. Not as intense as the time there was a 3.5 practically right under the house in Santa Teresa -- I could actually hear the frame of the house groaning with that one.

No damage. Just a reminder of the power of the earth.
