Volcanic activity began in the Yellowstone National Park region a little before about 2 million years ago. Molten rock (magma) rising from deep within the Earth produced three cataclysmic eruptions more powerful than any in the world's recorded history.View full answer
Moreover, Is Yellowstone ready to erupt?
Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. ... In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. This comes out to an average of about 725,000 years between eruptions.
Keeping this in mind, How many times has Yellowstone exploded?. Yellowstone has had at least three such eruptions: The three eruptions, 2.1 million years ago, 1.2 million years ago and 640,000 years ago, were about 6,000, 700 and 2,500 times larger than the May 18, 1980 eruption of Mt. St. Helens in Washington State.
One may also ask, Who would die if Yellowstone erupted?
Scientists have talked about what could happen if Yellowstone's supervolcano were to erupt in a modern-day setting throughout the United States. One scientist spoke to medically daily and reported that scientists predict that 5 billion people in total would die as a result of an eruption.
What is the most dangerous volcano in the world?
A recent PBS documentary identified Kilauea, on the island of Hawaii, as “The Most Dangerous Volcano in the World.” A curious choice, in my opinion, for any rating of a volcano's danger must take into account both the intrinsic hazard and the number of lives at risk. Eruptions of Kilauea are certainly spectacular.
Should the supervolcano lurking beneath Yellowstone National Park ever erupt, it could spell calamity for much of the USA. Deadly ash would spew for thousands of miles across the country, destroying buildings, killing crops, and affecting key infrastructure. Fortunately the chance of this occurring is very low.
How does a 'supervolcano' eruption work? Below Yellowstone National Park, there's a huge magma reservoir that's responsible for all the geysers and hot basins, bubbling away — and it's precisely this reservoir that has the potential to destroy humanity.
Yellowstone volcano eruption simulations show an unexpected blast would produce ash fallout from the Northwest US down to the southern tip of Florida. 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.
“There's no indication that the Yellowstone magmatic system is really going to be waking up anytime soon,” he said. That's good news as Yellowstone National Park is expecting a record year for visitation in 2021 and an eruption would likely put a dent in it.
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. ... YVO gets a lot of questions about the potential for Yellowstone, or some other caldera system, to end all life on Earth.
Q: Is the volcano dormant or extinct or still active? A: The Yellowstone Volcano is still active. Evidence for the activity of the Yellowstone Volcano are the 1,000 to 3,000 earthquakes per year, active ground deformation, and the over 10,000 thermal features found in Yellowstone.
Given Yellowstone's past history, the yearly probability of another caldera-forming eruption can be approximated as 1 in 730,000 or 0.00014%.
1. Yes, it will! But the next eruption is likely to be pretty small, just a bit of lava extruding with maybe minor amounts of ash. ... If the next enormous eruption happens in our lifetimes, there will of course be death and destruction, but not enough to destroy the United States, or even just the American West.
The lack of a peak or potential outlet for gas, heat and pressure building underground increasess the likelihood that “the entire surface above the underground chamber, which can be many miles wide, is blown away by a titanic explosion that can be thousands of times more powerful than that of a regular volcano.”
Is Yellowstone a volcano? Yes. Within the past two million years, some volcanic eruptions have occurred in the Yellowstone area—three of them super eruptions.
In short, yes. Below Yellowstone Park lies a caldera that would knock not just your personal socks off, but the socks of those worldwide. Scientists recently discovered that the caldera is 55 by 20 miles (89 by 32 kilometers), and 3 to 9 miles (5 to 14 kilometers) below the surface [source: News.Au].

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).
