Supervolcano beneath Mt. St. Helens?

nhytefall writes: We've all heard of the super-volcano that is Yellowstone Park. In short, it is an extremely large zone of conductive material, capable of producing a truly cataclysmic eruption. Apparently, now the Mt. St. Helens to Mt. Ranier corridor is also one of these zones. Be wary, Seattle... Be wary.
