Why is Yellowstone so much more explosive than Hawaii?

Why is Yellowstone so much more explosive than Hawaii? Yellowstone's magma is thick and viscous, trapping gases within it. When the magma reaches the surface the trapped gas is violently released in the form of explosive eruptions. Hawaii's volcanoes are fueled by mostly thin, runny magma.

What states are in danger if Yellowstone erupts?

Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted by falling ash (the amount of ash would decrease with distance from the eruption site).

How long would the winter last after a Yellowstone eruption?

Location of past Yellowstone super-eruptions That triggered a dramatic 6- to 10-year global winter and (according to some) may have nearly wiped out the nascent human race. On average, the Earth has seen roughly one super-eruption every 100,000 years, although that's not an ironclad law.

What are the 3 super volcanoes in the US?

Would Yellowstone cause an ice age?

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.

Would humanity survive Yellowstone?

Can we survive a Yellowstone eruption? A massive eruption of the Yellowstone supervolcano would spread deadly ash for thousands of miles, killing plant life and affecting humans in its path. Humans who were in its path would surely die, but it would not mean the extinction of the entire human race.

What is the biggest threat in Yellowstone?

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.

Where is the safest place to be if Yellowstone erupts?

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.
