Yeah...that would make one worry a little bit. Then again, it is California, you or I could just guess that far off, and have a pretty good shot that one will happen.
Wonder how much the next earthquake will cost the taxpayers...
These regions are large and all fairly active. Bet that there'll be events over any given time and you can't go wrong. Nailing the magnitude is another matter, unless there's a history.
The urban LA region gets pretty solidly hit every 20 years or so; usually a ~5.0 and then a larger 6.5 or so. 1933, 1956, 1971, 1994.... How much you wanna bet we get hit again by 2015?
