There have been a number of estimates of which west coast fault is going to go next and how big it will be. The last I read, there were a lot of geologist-types who felt the Cascadia fault was next in line for something unpleasant. When that one gives, expect a lot of trouble in OR. Our building codes are weak, largely unenforced and have a boatload of loopholes. Also, nearly all the dams are in a state of imminent failure. However, I wouldn't be surprised if the Hayward fault goes first. That one runs through the football stadium at U.C. Berkeley and will probably drop all the bridges that cross the Bay when it starts dancing. I remember reading an estimate that said it had a better than 50% chance of a large quake in the next twenty years.

There was an article in a S.F. paper a few years ago that claimed the water supply to S.F. is vulnerable to rupture in the event of a large quake. As you may know, The City wasn't lost to the 1906 quake, it was lost to the fires that couldn't be put out because the water supply had ruptured. It's like deja vu all over again.

However, a person on the west coast is probably a lot more likely to be run over by a motorist than to die in an earthquake.
