My First Earthquake

I've been studying faults and earthquakes for over a year now, but it was not until just now that I felt my first trembler. I'm currently visiting my fiancé's family in Los Altos, CA. We were all sitting around the breakfast table when all the sudden the plates all started rattling. It was very brief, only a couple seconds long, but it was definitely an earthquake.

The USGS has it initially sized at a magnitude (local magnitude, ML) of 3.1
