Volcano Songs

Mt. Rainier’s roiling innards make constant noise — and by listening, geologists can tell what kind of mood it's in. Looming on the horizon like a holographic ice cream cone (when we can see it), Mt. Rainier draws eyes skyward everywhere in Puget Sound. But fear mingles with our fascination: Is it going to blow? And if so, when? Thankfully, ‘The Mountain’ is one of the most monitored volcanoes in the world, and geologists can decode what’s happening with Rainier in part by isolating the unique sounds coming from within. Their findings can tell us when we should worry — but they also reveal that our entire region vibrates with an eerie music all its own.  For this week’s episode, we’re joined on our trek to the edge of glaciers and deep within the rock by Kate Allstadt, of the U.S. Geological Survey, and Harold Tobin, director of the Pacific Northwest Seismic Network. --- Credits Host: Ted Alvarez Music/mixing: The Explorist
