Mount St. Helens, Washington State
When Mount St. Helens erupted in 1980, the resulting destruction led to the death of 57 people, thousands of animals, and wiped out 200 square miles of forest. The eruption reduced the height of the mountain’s summit by nearly 1,300 feet. Four decades later, the forest area remains barren. The United States Geological Survey expects that further eruptions will take place, potentially causing more devastation that could affect the entire Pacific Northwest.
