OK Don, They have 21% for the San Andreas for a M6.7+ in the next 30 years. That may be reasonable-but it includes a lot longer part of the San Andreas than would be ruptured by a 6.7. I recall that the probability for a rupture in a larger quake of the northern San Andreas (probably Golden Gate on north) was really low-like 2% or 4%......I was referring to that. The 21% includes the Peninsular segment, which may be more ready...... Chris
