'Geospeedometer' Confirms Super-eruptions Have Surprisingly Short Fuses (vanderbilt.edu)
Science_afficionado writes: Super-eruptions – you know, those gigantic prehistoric volcanic outbursts that throw 100 times more superheated gas, ash and rock into the atmosphere than run-of-the-mill eruptions like Mt. St. Helens — tend to pop-off within a few hundred years after their underground body of magma reaches a high enough proportion of molten rock and low enough proportion of crystallization to become explosive. That's a much shorter time than geologists had thought. That means if the hot spot under Yellowstone, for example, were to turn explosive, then we would only have couple hundred years to prepare for an eruption that could blanket the entire continent with up to 3,600 cubic miles of ash and rock!

More Chicken Little crap from /.
Quite simply put, if your number is up, you're going to die. Come tell me when they think it's going to start the cycle and we can prepare appropriately. Until then, this is more "making news" and I'm quite fucking tired (as are many...) of this bullshit.
The Columbia river gorge in Washington state was carved from a series of cataclysmic floods, the largest of which carried 13 times the volume of the Amazon river.

Wow!
If you think that all problems can be fixed at the end of a gun, think again, idiot. Those that refuse to learn the lessons of history etc ...
blanket the entire continent with up to 3,600 cubic miles of ash and rock!
In the case of an eruption like that, clearly the ruined lawn of Americans would be the pertinent problem. Global winter and loss of crops worldwide? Who gives a shit.
Start now.
Where did the 3,600 cubic miles of ash and rock figure come from?
The largest 3 previous explosions of the Yellowstone caldera happened 2m, 630k, and 1.3m years ago releasing an estimated 600, 240, and 67 cubic miles of ash and rock. That's a combined 907 cubic miles, a quarter of what the summary suggests could happen. I can't find that number in the article anywhere. 3600 cubic kilometers converts to approximately 863.7 cubic miles which would be more believable. The largest volcanic eruptions ever believed to happen top out at 8,600 cubic kilometers, ~2063 cubic miles.
That's so scary. It's like I could hear that the super volcano would erupt and then only have time to live my entire life and die before my great great... great grand children who I would never meet would possibly suffer from the eruption!
Well, one of those lessons of history is that if you're trying to get from point A to point B and there's a fence in the way, then more/better guns than the guys with the fence plus better tactics, can get you to point B. Not every problem can be solved with guns, but the simple sort described in this thread is of the kind that can.
I've seen worse.

Where did the 3,600 cubic miles of ash and rock figure come from?
It's probably based on the size of the magma chambers underneath Yellowstone which are much larger in volume than the eruptions from Yellowstone.
While you are currently right about the estimated size of known, possibly single volcanic eruptions, it's worth noting that ongoing volcanic eruptions can be much larger, such as the Siberian Traps, which are thought to originally have been as high as seven million cubic km of lava over a million year period.

It was precisely calculated by taking the realistic number and adding the "scare multiplier" to it in order to increase page views.
Whew! So it's only 600 or so cubic miles.
Thank god.
(-1: Post disagrees with my already-settled worldview) is not a valid mod option.
3600 cubic miles is roughly 10 percent of the mass of earth. If that much erupted I think nothing would exist afterwards, especially N Am. Earth's orbit would probably be changed if there was an eruption that size.
I had a super-eruption recently. Let's just say Daisy Ridley was a fiiiiiiine choice for Star Wars.

can get you to point B.
Well, "you" collectively, not necessarily "you" personally, as even with better weapons and tactics, it is not a 100% guarantee that every person will survive without harm. Too often people suggesting guns are a solution act like they are a magic forcefield or that bad guys have worse aim than a stormtrooper.
3600 cubic miles is roughly 10 percent of the mass of earth.
Huh?
3600 is a little less than 16 cubed (2^12 = 4096). So it's a volume contained in a cube less than 16 miles on a side.
That's a lot less than 10% of the volume of the Earth.
God said, "div D = rho, div B = 0, curl E = -@B/@t, curl H = J + @D/@t," and there was light.
wait, what? How small do you think the earth is! I can only guess that you think 3600 cubic miles is the volume of a cube of side 3600 miles. Usually this is meant to be the volume. so, for example, the volume of a cube of side 15 miles is around that much.
we would only have couple hundred years to prepare for an eruption
I think you meant "we would only have a couple hundred years to sit on our asses denying that an eruption could ever happen, and even if it did erupt there's nothing we could do about it anyhow".
but there's probably enough energy in the Yellowstone magma chambers to 100% power all our (humanity's - the world's) energy requirements for absolutely everything we do. Tapping it fully, MAYBE we could keep it from getting any hotter. Suspicious we could not construct enough heat sinks to actually cool it at all, its too big.
Hollow Earth theory bro, hollow earth.
Yellowstone is one... are there any others? How many? Where?

Yes. I want your shotgun. Not all shotguns - just yours anon - just yours. /s/ The Democratic Party.
Perhaps you're thinking "3600 miles cubed" instead of "3600 cubic miles". They're not the same thing.
"I do not agree with what you say, but I will defend to the death your right to say it"
3600 cubic miles is roughly 10 percent of the mass of earth.
You might be confusing the term "3600 cubic miles" with "3600 miles cubed".
The standard interpretation of "3600 cubic miles" is that it's the volume that results when you take one cubic mile and multiply it by 3600.
The standard interpretation of "3600 miles cubed" is that it's the volume of a cube that is 3600 miles long on each side.
There is at least 10 orders of magnitude in difference between these two interpretations.

The volcano ate too much at Taco Bell (aka Toxic Hell).
That Democratic Party should put in a constitutional amendment to be voted upon than. The constitution guarantees the rights of the people to own firearms, no matter how much the DNC wants to claim otherwise.

Taco Bell uses Silicon Dioxide as an anti clumping agent in their meat, so it is possible I suppose that a volcano would want some as that is simply sand.
