Oregon Subduction?

Doc;
These quakes:
2.7 2001/05/06 08:11:07 45.248N 123.509W 52.4 35 km (22 mi) SE of Tillamook, OR
1.4 2001/04/26 08:40:18 45.159N 124.390W 21.3 54 km (34 mi) SW of Tillamook, OR

are on or/and near the Cascadia SZ. I have not looked at any catalogues but my guess would be that subduction quakes in this area are not unusual. This is also an area which I have been watching closely for a few years now. It is where SFdF hits the NAP and dives and it is north of locked Gorda by quite a distance. I am certain you knew of that. The SZ depth Q's extend apprx. 50-75+ miles inland on the Oregon Coast.
Another thing I have not heard much of after its announcement and that is the reverse way in which Oregon Coast is turning as opposed NAP. It sounded to me like push came to shove and I was waiting for some follow-ups on the news but it has been a few months now and money is not forthcoming for some studies...
Andy Micheals told me numerous times that Menlo nor Berkeley nor UofW had any real good tech tools in the areas from the MTJ north to apprx. Portland lat. He said best guess for mags on Qs in that area were from Golden. Maybe something has changed or maybe the depth is a bit under. Reckon one would have to see if a final resoultion came in on those two Qs Petra mentioned as per above.
