WASHINGTON (CBS13/AP) — Government scientists are classifying 18 U.S. volcanoes as a “very high threat” because of what’s been happening inside them and how close they are to people.
The U.S. Geological Survey is updating its volcano threat assessments for the first time since 2005. The danger list is topped by Hawaii’s Kilauea, which has been erupting this year. The others in the top five are Mount St. Helens and Mount Rainier in Washington, Alaska’s Redoubt Volcano and California’s Mount Shasta.READ MORE: Fallen Tree Blocks Multiple Lanes Of Highway 99 In Lodi

Among those where the threat score is higher are Alaska’s Redoubt, Mount Okmok, Akutan Island and Mount Spurr. Threat scores also rose for Oregon’s Newberry Volcano and Wyoming’s Yellowstone.
The last eruption in California was Lassen Peak in 1915. Mount Shasta erupts every 300 years on average; it’s due to erupt in the next 68 years.MORE NEWS: 'We Have To Do Something': Assembly Passes Bill That Would Allow California Parents To Sue For Social Media Addiction
