Beneath its snow-covered peaks lies a chain of active volcanoes, including Mount Rainier, Mount Hood, and Mount St. Helens. This range creates rivers, feeds forests, controls weather, and supplies water to millions. At the same time, it sits on powerful tectonic forces capable of eruptions, earthquakes, and massive lan

This week, all volcanoes in the Cascade Range of Washington and Oregon are at normal background levels of activity.
