This is right down at the bottom of the previous M7ish strike-slip earthquake, This one is oblique thrust.
The big question is which track? I am adamant about the buried strike-slip fault that defines the island, and goes way down into Seattle. This is the real threat to Vancouver, but it is buried under a ton of sediment. Pooh-pooh on the subduction zone, that is the worst-defined zone on the planet. Other cities will tumble before this one does anything.
Being adjacent to the old quake, it could be a left-over or the start of the next section. I make no predictions since my previous extrapolation was assuming the earthquakes were walking North to Alaska.
Just like Oklahoma, we could use some deep imaging here.
