Penny..what? Yes, if you are talking about the 2004 and 2005 Sumatra quakes, sure, they had some distant effects. But, why would they have anything significant on the Vancouver Island swarm...is a plate boundary...Pacific plate is being dragged under Aleutians by subduction...making big right lateral zone along Britich Columbia, and the small plates are subducting under the Pac NW. Sumatra can't do more than tickle that...and the tickling was strongest at the time of the quakes.
