What would be the blast radius of Yellowstone?


What would be the blast radius of Yellowstone? Based on past research and the general location of the volcano itself, the blast radius of Yellowstone's calderas is quite large. When it comes to lava and magma flows spewing forth from this volcanic eruption, Yellowstone National Park would likely need to evacuate everyone within a 40 to 50 mile radius.


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.


How far would Yellowstone volcano affect?

Yellowstone Super Volcano FAQ If 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.


How much would the temperature drop if Yellowstone erupted?

Geologists believe the ash from the eruption would encircle the globe in as little as 48 hours, and make temperatures drop by a minimum of two degrees celsius for as long as 20 years. The cooling of the Earth could be catastrophic for the planet's fragile ecosystem, kicking off a chain reaction of extinctions.


How many nukes is Yellowstone?

Some stats on the Yellowstone supervolcano: A super-eruption would equal the force of 1,000 Hiroshima atomic bombs exploding every second. You could fit Tokyo, the world's biggest city, in Yellowstone's super-volcanic crater.


What would happen if Yellowstone was nuked?

For an eruption to occur, a volcano needs a large amount of liquid magma and enough pressure to make it ascend to the surface. While nuking Yellowstone may not cause it to erupt, a nuclear blast on U.S. soil will inevitably be very damaging to both animal and human life.


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.


What supervolcano is bigger than Yellowstone?

Which is bigger Mauna Loa or Yellowstone? Mauna Loa volcano is the largest volcano on Earth. It is over 30,000 feet tall from the seafloor where it was born to the summit, which is 13,684 feet above sea level.


Could an earthquake trigger Yellowstone?

Not in any significant way. Large, distant earthquakes can cause changes to geysers and hot springs within Yellowstone because shaking fractures the fragile subsurface hot water plumbing systems. However, significant tectonic stresses are not transmitted very far.


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.
