Yellowstone Super Volcano FAQIf the Yellowstone supervolcano ever erupted, it would bring about a calamity for most of the United States. The supervolcano would spew deadly volcanic ash for thousands of miles across the entire country.
A: For the most likely type of volcanic eruption in Yellowstone, everywhere would be safe except in the immediate vicinity of the advancing lava flow. In the highly improbable event of a large catastrophic eruption, the great the distance from the eruptive center, the safer it would be.
No.A very large volcanic eruption would cause a severe cold period called a volcanic winter, but not an ice age. Volcanic eruptions cool the planet by creating a fine aerosol of sulfuric acid in the stratosphere. The highly reflective droplets prevent a portion of the sun's light from reaching and heating the surface.

Yellowstone's greatest geological threat isn't a supervolcano. It's a magnitude-7 earthquake. YELLOWSTONE NATIONAL PARK, Wyo. – While concerns about a potential eruption of the supervolcano beneath this iconic park may garner the most alarming headlines, a more likely hazard in the coming decades is a large earthquake.
If heat could be bled off of the magma chambers, cooling and solidifying them, not only would that (theoretically) stop the volcano from erupting, but the heat could be used to generate electric power with a geothermal energy plant.
The largest dormant volcano in the world, Haleakala, makes up a large part of Maui. Mount Haleakala is also called the East Maui Volcano. Haleakala is considered a dormant volcano because it has not erupted in a long time, but it could erupt again in the future. Haleakala is a huge shield volcano.
