Geyser Guys & Gals, You folks (education - university) that like to study the frequency and predicability of various geysers, hot springs, dry holes, etc., could or should be able to have a heyday with the seismic activity of the St. Helen's seismograph displays at the link below. There is a very good repeating pattern to the activity and it would be interesting to hear some good theoretical explanations as to what's the cause/s of such patterns. (bubbles, lava movement, mountain heartbeat, etc.) How about giving it some thought and feedback..... It's just another Yellowstone in it's infancy, but a much smaller scale. Just thought I'd again put in my 2-pennies worth....
