Is Mount Hood due to erupt anytime soon?
No one knows when a volcano is going to become active again. The Cascade Range is one of the most active volcanic areas in the world, and new activity is to be expected. The Three Sisters area in central Oregon is perhaps the next most likely area to see volcanic activity, as it has been swelling several centimeters per year for about 10 years now. Mt. St. Helen’s is still erupting, although quietly, in a dome-building eruption. But that could change at any time. Mt. Hood has not given any signs that it is going to become active soon, but it is still considered ‘active’ because the last activity was only a few hundred years ago.
