After shocks of 4.4 and 5.0 were also recorded.
CBC reports that the three large quakes were unusual since it was not within the Cascadia Subduction Zone (where the Juan de Fuca and North American plates interact). Instead, they occurred about 118 miles southwest of Port Hardy, a town at the northeast corner of Vancouver Island. KIRO 7 reports that this is where the Explorer plate meets the Juan de Fuca plate.
The looming “Big One” that is expected to rock the Pacific Northwest will likely come from the Cascadia Subduction Zone.
