Mapping a Monster Volcano 105
bmahersciwriter (2955569) writes In one of the biggest-ever seismology deployments at an active volcano, researchers are peppering Mount St Helens in Washington state with equipment to study the intricate system of chambers and pipes that fed the most devastating eruption in U.S. history. This month, they plan to set off 24 explosions — each equivalent to a magnitude-2 earthquake — around around the slumbering beast in an effort to map the its interior with unprecedented depth and clarity.

I live within the blast radius (Portland) of the majestic Mt St Helens. I saw the 1980 eruption from my back yard. 24 explosions around the mountain? What could go wrong?!
I lived quite a bit further away, about an hour north of Seattle, but we actually felt the blast as a minor tremor. Someone in my family actually joked "Well, there went Mt St Helens". There was quite a bit of news about a possible pending eruption, of course. We were pretty shocked when we heard what had actually happened though.

"Monster Volcano" is perhaps a bit overstated, but comparing it to a super-volcano-potential such as the Yellowstone Caldera is perhaps a bit unfair. After all, no volcano in the world today can really compare to the potential of that one.
I live nearby (relatively speaking), and got a chance to see the devastation first-hand within the first year or two after it occurred. The forest service built a viewing station where you could look out over the devastated landscape, and, even neater, watch the forest start to grow back. It's easier to dismiss it as geologically minor when you haven't personally seen the miles and miles of trees snapped and laid down like so many matchsticks. On a human scale, it's incredibly massive, and was damn impressive to see.
