Nothing says "Welcome to the neighborhood" like signing an acknowledgment of the potential damage a volcanic eruption could have on your home. That's what residents in one county in the shadow of Puget Sound's Glacier Peak have to do when they buy land. Considered more explosive than Mount St. Helen's, whose 1980 eruption caused the world's largest landslide to date, Glacier Peak is ranked by the U.S. Geological Survey as one of the highest-threat volcanoes in the country.
The problem is that, while Mount St. Helen's has been under constant surveillance since its last eruption, Glacier Peak is not nearly as well monitored. The only warning signs that it's about to blow will be a series of earthquakes, making all 10,541 feet of it a colossal threat.
