Thanks Canie

The fatality range seems high: is higher than the Field et al study (2005) for a large Puente Hills thrust. I have not seen a 3D ground motion simulation for the N-I fault. On the other hand, to say San Onofre will be OK must be presuming that the northern onshore part breaks. If the offshore part breaks, it is close to San Onofre. But, perhaps of more concern is whether the Oceanside thrust, responsible for the continental slope, is active. I'm supposed to be working on that.

Eric Frost lead a field trip in 1994 that included a stop at San Onofre and he mentioned that a big piece of coastline not too far away had failed/slipped into the ocean (1978???). The geology at San Onofre is similar (I think?).
