Keeping an eye out

Mount St. Helens is the most active volcano in the Cascades. It's major eruption in 1980 has been succeeded by about 10 other smaller eruptions and maintains near-constant microseismicity. The first pictures show one of the close-in monitoring stations at Windy Ridge. The USGS Cascade Volcano Observatory maintains a number of large monitoring stations close to the mountain, near the vent, where they've been armored to protect from eruptive activity. These stations typically include a seismometer (seismogram here), a GPS station (the white dome), and other equipment like geophones or a webcam. Volcanoes never erupt spontaneously, they are always preceded by some kind of activity - usually small earthquakes - and let you know when they're ready to go. St. Helens hasn't done anything since about 2010, taking a well-deserved rest after the major lava dome growth in 2004-2008.

Around the mountain to the southeast, you can hike through the Plains of Abraham's pumice fields and past the slot-canyon head of Ape Canyon to the rim of the Muddy River, where another monitoring station reports seismicity and GPS data. The GPS stations observe the shape of the volcano over time. As gas, fluids, and magma move around inside the mountain, the surface deforms. Rapid or dramatic deformation is often indicative of impending eruption or other activity, and is one of the most important parameters in the volcanologists' arsenal.

page 553 - under the earth magma is roiling. Ceaseless.

If it stops, we're dead.

It will escape from time to time because it must. Explosive eruption or languid flow, it arrives as lava and burns what it touches. Or sometimes just what it breathes on.

I have to keep thinking to see what comes out.

Funny story: according to the myths of local native tribes, Mount Saint Helens was a woman who was in a love triangle with Mount Adams and Mount Hood. Yes she is acting up.
