Well I had my first medium size earthquake this evening. It was fun. It was a 4.2-4.3 centered about 6 miles away in the hills. It lasted about 5-10 seconds and katy thought our glass cabinets were going to fall over. I felt a few 3.x ones out here as well and those just sound bigger than they feel. They feel like a truck has driven into the building. This one did some good shaking. Here is our the shake map: USGS Shake Map
