USGS Research Publishes Updated List Of U.S. Volcanos With Highest Danger To Erupt

The United States Geological Survey (USGS) updated its list of American volcanos with the highest probability of erupting. Yes, 2018 is a scary time in the natural world. We have to worry about super-hurricanes, climate change, earthquakes, and as the USGS kindly reminds us– catastrophic volcanic eruptions.

*The last time this list was updated was back in 2005. 

The Most Dangerous Volcanoes In The United States:

  1. Kilauea, Hawaii
  2. Mount Saint Helens, Washington
  3. Mount Rainer, Washington
  4. Mount Redoubt, Alaska
  5. Mount Shasta, California

Volcanos provide excellent terrain for backcountry skiers. It is easy to notice that most of these peaks are popular with the ski and mountaineering crowd.

Mount Shasta, Mount Rainer, and Mount St. Helens are part of the Ring Of Fire tour where skiers tackle major skiable volcanoes.

While it is concerning that these popular mountains are at-risk for an eruption, the majority of US volcanoes have a decreased threat level. There are 161 active volcanoes in America.

The agency said a dozen volcanoes have jumped in threat level since 2005. Twenty others dropped in threat level.

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. – CBS Local San Francisco
