Don, Chris, John,

Thanks for cool comments. Going back to what John and Chris said, yes I've read some abstracts about the seismic debt socal might be in. My basis for suggesting future decades of sleep was just based on looking at past. There aren't very good records prior to 1857, supposedly there was a large one in 1855. After 1857 there was 1933. Then 1971. So if you look in the populated areas of LA from 1857 to 1933 and from 1933 to 1971, we witness whole lifetimes where people in greater LA never felt anything more than an occasional bumps. Then we get Whittier, Northridge, Big Bear, Landers and Hector all in like 20 years. If the LA area had sleep from 1933 to 1971 and now nothing since 99, yes maybe sleep prevails again, OR, we start the cyle to releive the slip that Chris indicated.

I guess these dynamics is what drives the big question of prediction. If we know for sure what certain slip models are, its frustrating not to be able to pinpoint the exact cycles.
