There are currently 169 active volcanoes in the United States. With Mount Kilauea in Hawaii currently erupting, we’re reminded how powerful and destructive volcanoes truly are.
Volcanoes are a natural phenomenon that we have no control over. All we can do is try to get out of their way. But how many are an actual threat? From a string of volcanoes in the Cascade Mountain Range to a supervolcano beneath the grounds of Yellowstone National Park, these are the most active and threatening volcanoes in the United States.
Mount Rainer Volcano, Washington
The real fear behind the potential eruption of Mount Rainer is that it’s covered with more snow and ice than all of the other volcanoes in the Cascade Range combined. This means that it would lead to an unstoppable amount of lahars or volcanic mudflows.
In past eruptions, Rainer’s lahars have made it all the way to the Puget Sound which is more than 62 miles away. Currently, that is a very developed area, which would be right in the direction of the lahars. Rainer is known to have activity every 500 to 1,000 years with its last eruption being over 500 years ago. Luckily, it appears the volcano isn’t showing any signs of movement.
