More than half a billion people on Earth live in the shadow of an active volcano. Growing up, I was one of them.
I spent my childhood in Tacoma, Washington, observing the gorgeous ticking time bomb that is Mount Rainier. From this vantage point 40 miles away, the mountain is pale blue and white, etched with the dark shadows of glaciers. Its silhouette sits in the foreground during sunrises throughout the year. In the summertime, the full moon rises right behind it.
Though Mount Rainier hasn't shown any hint of activity for a century, and its last major eruption was about 1,000 years ago, scientists believe the magma beneath the mountain could rise again.
