The supervolcano in Yellowstone National Park could cause an "ultra-catastrophe," warns an extinction events writer. The full eruption of the volcano last happened 640,000 years ago. The blast could kill billions and make United States uninhabitable.View full answer
Keeping this in mind, Can Yellowstone wipe out America?
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.
Accordingly, What states would be wiped out if Yellowstone erupted?. 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).
Also question is, Can Yellowstone destroy the world?
Roughly every 100,000 years, there's a supervolcano explosion somewhere in the world, the consequences of which can be fatal. If the volcano below Yellowstone National Park were to erupt, it would result in worldwide hunger and a volcanic winter (the cooling of the lower atmosphere).
Will Yellowstone cause extinction?
The most likely explosive event to occur at Yellowstone is actually a hydrothermal explosion—a rock-hurling geyser eruption—or a lava flow. ... As for the worst-case scenario, even previous Yellowstone supereruptions did not cause extinctions, and ash fallout on the other side of the continent was minimal.
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.
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.
The Yellowstone supervolcano — an 8 out of 8 on the Volcanic Explosivity Index — has erupted three times over the past 2.1 million years, most recently 640,000 years ago. A Yellowstone eruption would be like nothing humanity has ever experienced.
The USGS said: "You see, unlike science fiction stories, in which nuclear weapons seem to be the cause of, and solution to, many geological catastrophes, science fact tells us that you aren't likely to trigger a Yellowstone cataclysm with a nuclear weapon.
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].
“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.
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.
The Yellowstone Volcano is known to be a supervolcano because in the past (2 million years ago) it released over 600 cubic miles of lava and ash in one single event. When the last eruption took place about 640,000 years ago it is believed that it caused the last ice age.
The eruption of the Yellowstone supervolcano
The park has experienced three supervolcanic eruptions in the ancient past with the most recent explosion happening 640,000 years ago. ... The supervolcano is still active and could blow at any time.

Rising gradually to more than 4 km (2.5 mi) above sea level, Hawaii's Mauna Loa is the largest active volcano on our planet. Its submarine flanks descend to the sea floor an additional 5 km (3 mi), and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km (5 mi).
Vesuvius is still very much an active stratovolcano, with the city of Naples and its 3 million residents only a mere 12 kilometres away. ... Whilst these efforts are being administered, there are a multitude of visitors that come to see what the destruction of Vesuvius did to Pompeii.
