Yellowstone, one of the world’s largest active volcanic systems, has produced several giant volcanic eruptions in the past few million years, as well as many smaller eruptions and steam explosions. Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely.

Is Yellowstone dormant or active?
Q: Is the volcano dormant or extinct or still active? A: The Yellowstone Volcano is still active. Evidence for the activity of the Yellowstone Volcano are the 1,000 to 3,000 earthquakes per year, active ground deformation, and the over 10,000 thermal features found in Yellowstone.
How much would the Yellowstone volcano destroy?
In all, the YouTuber says FEMA (the Federal Emergency Management Agency) estimates the volcano would do $3 trillion worth of damage, which equates to approximately 14% of America’s GDP. The loss of life, however, would, of course, be the most horrific aspect of event.
