Hi Don,

That's good material, but it doesn't answer my questions. I'm not talking about a hop, skip and jump event, I'm looking specifically at the Victoria/Vancouver area to the north and perhaps the southern areas south of Olympia to the Oregon border.

IE: [block B = Olympia] [block A = Victoria/vancouver] [block C= Southern WA] Is there any reason to believe block's A & C are more likely to move since block A did? Any other location is not relevant to my question. I want a specific answer to a specific question. Then we must look to historical events. Has there ever been a time when this exact set of parameters has played out before? I don't know, but I'd like to.

Now, let's throw some idea's around about the San Andreas or other faults in the area. Since Loma Prieta it has been thought that the section north of Loma Prieta from SF to San Jose might be a gap and possible for a quake. But we also have the Hayward fault that hasn't produced the expected mirror quake to Loma Prieta. But where was the last 5.0 quake in these given area's? Bolinas, on the San Andreas. Thus we would have to skip the SF Peninsula and go north. Do we also skip the lower section of the Hayward fault and look at the southern end of the Rodgers Creek? Is this a Hopscotch Hypotheses? Food for thought.
