What Would Happen If Yellowstone's Supervolcano Erupted?
Live Science ^ | 2 May, 2016 | Becky Oskin

Although fears of a Yellowstone volcanic blast go viral every few years, there are better things to worry about than a catastrophic supereruption exploding from the bowels of Yellowstone National Park.

Scientists at the U.S. Geological Survey's (USGS) Yellowstone Volcano Observatory always pooh-pooh these worrisome memes, but that doesn't mean researchers are ignoring the possible consequences of a supereruption. Along with forecasting the damage, scientists constantly monitor the region for signs of molten rock tunneling underground. Scientists scrutinize past supereruptions, as well as smaller volcanic blasts, to predict what would happen if the Yellowstone Volcano did blow.

Here's a deeper look at whether Yellowstone's volcano would fire up a global catastrophe.

Probing Yellowstone's past Most of Yellowstone National Park sits inside three overlapping calderas. The shallow, bowl-shaped depressions formed when an underground magma chamber erupted at Yellowstone. Each time, so much material spewed out that the ground collapsed downward, creating a caldera. The massive blasts struck 2.1 million, 1.3 million and 640,000 years ago. These past eruptions serve as clues to understanding what would happen if there was another Yellowstone megaexplosion.

Right... I guess an EMP would wipe out communication and lead to a huge loss of life. (is that the same, for all intents and purposes, as a massive solar flare that would burn people up instantly, or are they two different Doomsday scenarios?)

.. But the sulfur would lead to nothing that could grow for a very, very long time. So worse than the aforementioned....

..what would happen if the Yellowstone Volcano did blow?

Screaming and running, falling down and dying.

California would no longer vote Democrat and it would stop the Reconquesta. As a matter of fact there would be no California.

A question I ask a lot and never get an answer to.

What if we drilled into the mantle (3-5 miles down) or close to the magma chamber and blew a major hole in the covering magma dome? Would it release enough internal pressure (gases, heat) to lower that pressure without it erupting like a lanced big zit?

Or would it help the chamber to explode with the same amount of internal force it originally had?

I’m a big fan of blowing up things in order to cripple or destroy them, including tornadoes, very doable; tsunamis, probably doable for limited areas.

In fact I wrote a column about that subject years ago, entitled “Don’t complain about the weather, blow it up”! for the old www.augustafreepress.com. Later got thrown out as a columnist for being too conservative (i.e, honest about the Left).

Don’t think that column is still on their Archives but the main thesis was that explosives are nothing but air-pressure devices. Direct a powerful air-pressure blast against a critical part of a tornado and who should be able to collapse it like shooting out the near bottom of a spinning ice-cream cone, disconnecting it from the source of its growth, earth heat.

Re Tsunamis, you might be able to disrupt actual large waves before they hit critical land areas (i.e, Japan, Hawaii, Thailand, Ceylon, etc). Would take some serious explosives, i.e. small nukes or even large ones but it is just like standing in the surf using your body to block incoming waves. The broken waves continue on but you can stop a key part of the wave from hitting you sandcastle.

Sci-Fi meets science. You never know what you are going to get until you try it.

I thought racism caused Global Watming. Has the Pope decreed that it’s the other way around?

Actually the correct term is "Global Worming", but you're right about racism being the cause. Here's proof:

Well, as I said, if it’s medium or small, then you have to deal mainly with the ash fall.

That means transportation and probably power for whoever is downwind.

But if it is a supervolcano, then it’s all over. You are talking AT LEAST two feet of ash covering everything that is downwind. That means not months, but YEARS of nothing growing - at least nothing you could eat. And transport, power, food distribution, clean water, all these things would be gone. For all intents, for the rest of your life, which however you look at it, isn’t very long!

During the Toba eruption, there was over 200 million tons of SO2 pumped into the atmosphere. Temperatures plummeted by ten degrees celsius, not for a generation, or for 100 years, but for over 1000 years.

I have heard that men did indeed survive Toba - just barely. Worldwide population of mankind fell to 1000-3000 people.

It would cause less damage than Obama has.

Montana and Idaho need to be prepared to cover the climate damage caused by any eruption. Any shortfall in funds need to be covered by the USA.

That is only fair.

Another estimate I have seen was a remaining population of perhaps 10,000 people. At any rate a very small number, and from other things I have read, it was not until 20,000 years later that the human population had really begun to rebound.

I don’t think guys like Matt Dillon or Wyatt Earp would be able to do as much as martial law would.

Just kidding with you.

Like AGW, this calls for geo-engineering.
