Wow, JD is a geologist with the US geological survey as well... I've been keeping track of the quake activity as well as the opinions of the goelogists at washington state, and the USGS. They all seem to agree that the magnitude and the depth of the quakes as well as the longevity of this string of quakes marks a high probablility of an eruption. If you look at the timeline on the volcanic activity in the cascades St. Helens is the most active recently, as well as historically. According to various goeologist that know the makeup of the area and the history of the region they've made an educated assumption that it would be likely that an eruption will take place. Granted that it's the norm for water seepage to spur vulcan activity under the mountain that theory has basically been ruled out due to growth that has been detected in the lava dome. Just take a look here:
