According to research by New Zealand scientists, Mt. St. Helens could be a supervolcano.  These scientists believe that Mount St. Helens, Mount Rainier and Mount Adams appear to be linked by a deep column that leads to a pool of what could be molten rock.  This could mean is that all the volcanoes work together to form one supervolcano, with Mt. St. Helens at the center.  That would make it one of the largest supervolcanoes in existence, equivalent to the supervolcano under Yellowstone.  Such a supervolcano would have the potential of a world-changing cataclysmic eruption.   For more information, see the New Scientist.
