How big is the magma chamber in Yellowstone?
How big is the magma chamber in Yellowstone? The magma chamber is believed to be about 40 by 80 kilometers across, similar in size to the overlying Yellowstone caldera. The top of the chamber is about 8 km deep and the bottom is around 16 km deep.
How far would the damage go if Yellowstone erupted?
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 big is the plume of magma that sits under Yellowstone?
They found evidence for a plume that is 350 km (about 220 mi) in diameter extending from the core-mantle boundary all the way to the base of the crust at Yellowstone. The suspected plume is tilted to the northeast, probably due to circulation patterns within the mantle.
How deep is the crust at Yellowstone?
The Yellowstone Plateau region has crustal thickness of 47–52 km; this thick crust primarily manifests the Laramide age shortening associated with the Beartooth Mountains and the magmatic underplate that created the high-velocity lower crust beneath much of the Wyoming Province crust.
Can you go inside a magma chamber?
Thrihnukagigur Volcano is the only spot on earth where it's advisable to explore a magma chamber from the inside. The volcano has not erupted for 4.000 years and shows no signs of coming to life anytime soon, so it is safe to enter.
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.
How big would the blast radius of Yellowstone be?
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.
What would be destroyed if Yellowstone erupts?
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.
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.
How deep is lava in Yellowstone?
Two large reservoirs full of magma exist beneath the Yellowstone Caldera—one that's about three to ten miles beneath the surface, and another that's 12 to 30 miles below ground.
