This earthquake occurred at a subduction zone boundary where the Pacific plate dives beneath the North American plate. But this was a strike-slip earthquake inside one of the two plates, meaning the two sides of a fault slid laterally past each other rather than one going under the other.

I fell into a burning ring of fire I went down down down but the flames kept getting higher... Mt Saint Helen is in that ring

Thank you. Wonderful to see that detail. Are there really only a handful of seismic stations in Canada? Or do you not have access to the wider Canadian data?

We just aren't able to include all of them. But with additional data in, you can see some more there now: ds.iris.edu/spud/gmv/233...
