“…a volcano will do what a volcano wants to do.”

Definitely read the whole post, and follow the link for some interesting info on monitoring & activity.

“Earthquake Monitoring at Mount St. Helens.”

One of the best monitored active volcano’s in the Country.
“An average of 22 events per month of seismic activity are recorded.”

Ref- Volcano’s & the seepage-thread: “majority of gas emitted at Mount St. Helens is water vapor (H2O), followed next by carbon dioxide (CO2), and sulfur gases, including sulfur dioxide (SO2) and hydrogen sulfide (H2S).”

(Still investigating “volume” of volcanic-gas emissions. Government stats are good at concentration-levels but laboring to figure out some sort of world-wide emissions amount.)
