Is magma rising under Yellowstone?
A new 3-D model shows the 45-mile-wide (72-kilometer-wide), 410-mile-deep (660-kilometer-deep) plume of hot, molten rock rising under Yellowstone’s supervolcano.
How many years are we overdue for Yellowstone?
That being the case, there is still about 100,000 years to go, but this is based on the average of just two time intervals between the eruptions, which is meaningless.
Will the Yellowstone volcano wipe out the human race?
The answer is—NO, a large explosive eruption at Yellowstone will not lead to the end of the human race. The aftermath of such an explosion certainly wouldn’t be pleasant, but we won’t go extinct. How do we know? Because this “super eruption” experiment has already been run.
Would Yellowstone cause an ice age?
One of the most concerning effects of the amount of ash particles in the air would be on the climate. The ash would block out the sun causing the whole world to experience a sudden temperature drop of up to ten degrees. It would even spark a mini ice age.
What states would be affected 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 cold would the Earth get if Yellowstone erupted?
They found that an eruption like Toba would cool the Earth by about 17°F (9.4°C) after the first year (Figure 3), and the temperature would gradually recover to 3°F (1.8°C) below normal ten years after the eruption.
How much would the global temperature drop if Yellowstone erupted?
If Yellowstone erupted, global temperatures could drop 3-5°C and stay low for years. A prolonged volcanic winter, similar to the concept of a nuclear winter, could set in, devastating harvests and ecosystems the world over.
