42 for Loowit’s 42nd vol. 4: Menacing May
May had begun with an ominous quiet.
Ominous? Surely a restless volcano quieting down is a good thing!
Yeah, not when you’ve got one flank of the mountain growing a bulge like a demonic pregnancy and displaying worrying new thermal anomalies. Add in earthquakes and dramatic swelling, and you’re sure the volcano is ready to pop.

42 for Loowit’s 42nd vol. 3: Ominous April
For the people who lived and worked on the flanks of Loowit (Mount St. Helens), her awakening was both curse and blessing. Living with a restless stratovolcano isn’t safe nor comfortable. But the tourism it draws is great for the local economy. Locals leaned in, creating funny hats and shirts, renaming menu items, and finding other creative ways to capitalize on her activity.
For the scientists who flocked to her, it was the chance of a lifetime.

Volcanologists flocked to her slopes, installing equipment, taking measurements and photos, and flying over the summit as steam and ash spurted into the sky. They’d seldom had a chance to study an actively erupting composite cone so conveniently close to highways and large cities. Loowit was wonderfully accessible, and easy to observe, even in the Pacific Northwest’s capricious early spring weather. (more…)
41 Years Ago Today, Volcanic Hazards Awareness Expanded With A Boom
I’m middle-aged now, but back then I wasn’t even in kindergarten yet. That sunny May day, I was inside, glued to a television screen filled with a roiling gray haze of volcanic ash. Mount St. Helens had erupted with spectacular violence after a couple of months of unrest.

There was only one thing I could do once the shock of it wore off: I promptly grabbed construction paper and crayons and drew the volcano a get well card. She looked like it hurt.
It would be a couple of years before I began to grasp the scope of what had happened, and decades more before I knew how much the 1980 awakening, eruption, and aftermath had advanced the science of volcanology.
A Hero On Mount St. Helens: Remembering David Johnston
Dr. David A. Johnston is a person I’ve looked up to for most of my life. I first learned about him when I was a child, reading Marian T. Place’s book about the eruption of Mount St. Helens. He watched an active volcano. He warned a lot of people that she was going to violently erupt. He saved countless lives, but lost his own. He became a personal hero of mine, especially as I grew up and learned more about the work he did and the risks he took.
So I was super excited when I saw a whole book was being published about him. I bought a copy as soon as I could. Then…
