Does anyone know anything about the earthquake in seattle today? What happened with the plate boundaries?

I read up on this, and apparently the earthquake originated about 30- 35 miles below the earth's surface in a spot labeled the Cascadia subduction zone. As you recall, a subduction zone is where one plate sinks beneath the other. The exact cause of the earthquake seems to be blamed on a plate called the Juan de Fuca plate which is pushing away from the Pacific oceanic plate and toward the continental plate of North America.
