Hi Gerry,

I guess I am mystified when looking at seismic quiesense for Olympia, WA because in other area's where quakes have been classified as working according to that theory, they were using "b value" studies. In so far as I know, b value studies relate to small earthquakes, not a series of 5.0's prior to a subduction event.

I checked out Weimar's site and he surely worked hard to make things look simple. So I sent him an e-mail and asked him what he thinks.

To me, the quakes prior to Olympia, were simply a series of foreshocks pointing the way to that block moving, nothing more. Then comes the next question. If that is the case, where would you look for precursory quakes if you expected the Canadian block to move? Would they be in the same area or north of the Canadian block?

What about Oregon? Oregon has been quiet far longer than WA, so why wouldn't we expect Oregon to have a subduction event? Northern CA did in 1994. Ummm? Gosh.

What do you think?
