What would happen if Yellowstone volcano erupted?
What would happen if Yellowstone volcano erupted? If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate.
When did Yellowstone last erupt?
The Yellowstone supervolcano last erupted about 640,000 years ago. A sleeping giant is nestled in the western part of the United States. Though it stirs occasionally, it has not risen from slumber in nearly 70,000 years.
What happens if Yellowstone blows up tomorrow?
If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate.
What happens to UK if Yellowstone erupts?
If you somehow managed to survive the fast flowing lava, the thick ash cloud that would rain down would choke you to death. All the states surrounding Wyoming would certainly perish very quickly. The UK and the rest of Earth would not escape.
What countries would be affected by the Yellowstone eruption?
Volcanic ash fallout of more than 39.4 inches (one metre) would blanket Yellowstone's immediate vicinity in the states of Wyoming, Montana and Utah. The severity of the blast decreases further out form Yellowstone National Park but extends into Canada, Mexico and the East Coast.
How many people would be affected if Yellowstone erupted?
It would kill around 100,000 people instantly and make most of North America uninhabitable as huge amounts of ash and dust would be thrown into the atmosphere.
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.
How far would a Yellowstone eruption spread?
The total energy released would be equivalent to an 875,000 megaton explosion. The shockwave would kill 90,000 people. Most of the lava would fall back into the crater. Any flows would be slow and only spread 40-50km or so.
Can we stop Yellowstone from erupting?
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.
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.
