When will the world's largest volcano erupt ?

Its been sitting dormant below Yellowstone National Park for 600,000 years and is now overdue.
If it did explode it would do so with a force 1000 times more powerful than the eruption of Mount St Helens in 1980 spewing an ash layer 10ft deep over 1,000 miles. It isn't known when the eruption will occur, only that it will - it could be tomorrow or it could be in another thousand years.
It would explode with a force a thousand times more powerful than the Mount St Helens eruption in 1980. Spewing lava far into the sky, a cloud of plant-killing ash would fan out and dump a layer 10ft deep up to 1,000 miles away. Two-thirds of the U. S. could become uninhabitable as toxic air sweeps through it, grounding thousands of flights and forcing millions to leave their homes.

It's going to erupt, but I am sure that when scientists say that it won't happen any time soon, they're correct.

There isn't even a guarantee that it will erupt. It doesn't have the power to do it now, and it's in a shallow spot of the mantle. Give it enough time, and the mountains surrounding it are going to be piled on top, killing any chances of it erupting.

Give it enough time, and the mountains surrounding it are going to be piled on top, killing any chances of it erupting. Thats not really true at all. Take a look at a geologic map, or any map really, of the Snake River Plain. You can see where the volcano has blown each time, as the crust moved over it. So if given time there will be no mountains. As the crust will move just as fast if not faster then a orogeny.

It's a burp of lava than randomly came out in that area. But in all cases, notice that the only places that there have been eruptions have been in the actual plain, meaning the shallow part. Once the plains move away from the hotspot and the mountai... [More]

But in all cases, notice that the only places that there have been eruptions have been in the actual plain, meaning the shallow part. Once the plains move away from the hotspot and the mountains slide into place, the hotspot will be buried beneath and have nothing to do but sit and cool off. A orogeny can happen away from a boundary as well. I said orogeny because that is what I thought you meant, but I see now that you meant the crust moving mountains over the hotspot. And if I reme...

Yellowstone should just blow up rightnow and save us all the waiting and planning.

It would make a GREAT disaster movie, wouldn't it ? meow purr It's already been made into one. It has been broadcast on TV, even. Something worth noting, though: eruptions either produce ash or lava flows, not both. I doubt that's the only mistake in the article. Doug

It's just as likely to blow now that it is 1000 years from now. It's not if it's when, but were talking huge time scales. No likely in our lifetime, but just as possible as anyone elses becomeing more and more likely going into the future.

We'll have plenty of warning before Yellowstone pops its top. I've lived in WA all my life and remember when St. Helens flipped her lid. Heard it in fact. We knew up to a month or better before St. Helens blew and we knew it was iminent. The mountain was monitored, even evacuated. What they did miss was the TYPE of explosion it would be, where the whole side of the mountain essentially disintegrated (which is the same type of explosion Vesuvius experienced), but the did know it was going to be a BIG BIG boomer. It will be the same with Yellowstone, you'll know maybe even months before it's goi... [More]

from what i read today the Italian one is dead. on the history channel today the are doing Revelations and stated that if Yellowstone blows it will block out the sun for 40 years. oh and it is over due. no it's not dead Here I found this Two thousand years ago Mount Vesuvius destroyed Pompeii. Today, a larger, far more deadly supervolcano lurks on the other side of Naples. If it erupts, Campi Flegrei could wipe out all life in Europe. So why are British scientists battling the Italians for the right to poke at it with drilling rods? Read more: http://www.dailymail.co.uk/home/moslive/article-13... [More]
