Tech Times –
If the massive volcano that lies beneath the Yellowstone erupts, 90,000 people will get killed.
The eruption of the supervolcano would emit very high levels of molten lava on the Earth’s surface and very thick clouds of smoke in the skies. There would be no way out and two-thirds of the United States could be wiped out.
ummmm … wouldn’t 2/3 of 300 million = 200 million …not 90,000?
In the rare chances that an eruption of the Yellowstone supervolcano would ever occur in this lifetime, the majority of the U.S. would be put to a state of ‘nuclear winter,’ where a thick layer of ash would cover the landmass and block the sun, leading to very low temperatures.
A supervolcano can emit more than a trillion tons when it erupts. If the Yellowstone supervolcano fully explodes, molten layer could go up to about 10 feet thick. From the explosion site, the molten layer could travel to as far as 1,000 miles. It would be impossible to send out search and rescue teams, as the area would pretty much be blanketed in very high levels of volcanic residue. Even air travel would be suspended.
While the chances of an actual massive eruption in Yellowstone are very small, it’s always good to be aware of what could happen, if in case it does, experts say.
– Looks like the 90,000 would be the ones stuck in the molten layer in the thousand mile radius.
