The United States Geological Survey (USGS) has updated its volcano threat assessments for the first time since 2005. The danger list is topped by Hawaii's Kilauea, but where does that place Mt. Shasta and Crater Lake, the two active volcanoes in our region?

The United States Geological Survey (USGS) has updated its volcano threat assessments for the first time since 2005. The danger list is topped by Hawaii's Kilauea, but where does that place Mt. Shasta and Crater Lake, the two active volcanoes in our region?

The USGS assesses and prioritizes volcanoes based on hazards, recent activity and the exposure of people and infrastructure to those hazards; or how many people would be affected if an eruption were to occur. Both Mt. Shasta and Crater Lake are classified as "very high threats" with Mt. Shasta ranked #5 and Crater Lake ranked #17 out of 161 active volcanoes in the US.

Though this sounds alarming, it's important to note that all 18 volcanoes assessed as "very high", including Mt. Shasta and Crater Lake, did not change category or rank with this new threat assessment on October 25.

On November 21st, Meteorologist Caitlin Harvey will interview one of the scientists monitoring Mt. Shasta to find out what they look for when surveying the volcano and what we should be on the look out for.
