I was 16 and lived 60 miles N of Mt. St. Helens in 1980. It was an awesome time here.

The Mountains rumblings did start with Micro Quakes but also the mountain began bulging up to 2 feet a day.

From the Seattle Post Intelligencer

A group of scientists planned to visit the mountain Monday and conduct a flyover to test for carbon dioxide and sulfur gases, which could suggest the involvement of magma. They'll also erect additional seismic sensors and sophisticated global positioning devices to measure activity.

but also the mountain began bulging up to 2 feet a day. I would be very surprised if that happens. If it does, it would obviously be a bad sign.

I'm waiting to hear about data coming in from the tiltometers and other sensors they stuck on the beasty.
I'd say that since they haven't mentioned any bulging, the magma rising up the pipe is what's causing the micro quakes, but it hasn't yet reached the point where it will cause bulging yet.
At least I'm assuming so.
