How deep is the volcano at Yellowstone?

How deep is the volcano at Yellowstone? How large is the magma chamber that is currently under 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.

What is the largest supervolcano in North America is beneath?

Yellowstone Caldera The largest supervolcano in North America is beneath Yellowstone National Park in Wyoming. Yellowstone sits above a hotspot that has erupted catastrophically three times: 2.1 million, 1.3 million, and 640,000 years ago.

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.

What would happen if the volcano in Yellowstone 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.

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.

Is there a volcano bigger than Yellowstone?

Supervolcano in Southern Utah is 30 times larger than Yellowstone.
