I saw that. I have an ap on my I-pad called Quake Watch that is wonderful as you can isolate 1.0+, 2.5+, 4.0+, 5.0+, and 6.0+ quakes to double check and you are 100% correct. It shows a cluster of 2's by Petrolia but that's it. What bothers me is that it lines up awfully well with that 6.0 offshore Oregon. Plus, there was another of size offshore BC a week or two ago. It seems like the entire subduction zone is warming up in scales. Hope not, but fascinating.
Stay safe,
