Luckydog,
The earthquake was centered in West Napa, about 4 miles from our house. They are saying that the houses on the East side of Napa fared far better than those on the West side of town. The West Napa fault has not had any activity on it for thousands of years, so they never expected it to break open.
The damage that you see shown on TV of the damage downtown is because of unreinforced brick buildings that have been around since the early 1900s.
The damaged roads and broken water mains are all from West Napa. There were 90 broken water mains in an area suffering from severe drought, which is very sad.
Being shaken awake and tossed out of bed at 3:20 AM can really get your adrenaline going. We were without water for a few hours and without power for 6-7 hours. There was stuff broken on the floor in just about every room. Fortunately the house stopped moving before all our pictures fell off the walls, so only one broke. We worked cleaning up the house from 3:30am to 10:30 PM on Sunday.
We learned some very important lessons. One is to never leave red wine bottles on the dining room table. Because that red wine will make an absolute mess when it falls off the table and breaks open. Another important lesson is that when you live in California, you need to be diligent and secure your furniture to the walls.
