Yellowstone threatens the world

[Ldvs]

Unfortunately that's not some poor French joke. I watched a broadcast about super volcanoes yesterday and I was flabbergasted to discover:
1) the existence of super volcanoes
2) the hardly believable lethal impact they can cause

The Americans and Canadians here probably are more aware than us Europeans, that Yellowstone, the renown national park, is also a potential disaster for humankind.


Hidden deep beneath the Earth's surface lie one of the most destructive and yet least-understood natural phenomena in the world - supervolcanoes. Only a handful exist in the world but when one erupts it will be unlike any volcano we have ever witnessed. The explosion will be heard around the world. The sky will darken, black rain will fall, and the Earth will be plunged into the equivalent of a nuclear winter.

Normal volcanoes are formed by a column of magma - molten rock - rising from deep within the Earth, erupting on the surface, and hardening in layers down the sides. This forms the familiar cone shaped mountain we associate with volcanoes. Supervolcanoes, however, begin life when magma rises from the mantle to create a boiling reservoir in the Earth's crust. This chamber increases to an enormous size, building up colossal pressure until it finally erupts.

The last supervolcano to erupt was Toba 74,000 years ago in Sumatra. Ten thousand times bigger than Mt St Helens, it created a global catastrophe dramatically affecting life on Earth. Scientists know that another one is due - they just don't know when... or where.

Yellowstone National ParkIt is little known that lying underneath one of America's areas of outstanding natural beauty - Yellowstone Park - is one of the largest supervolcanoes in the world. Scientists have revealed that it has been on a regular eruption cycle of 600,000 years. The last eruption was 640,000 years ago... so the next is overdue.

Molten LavaAnd the sleeping giant is breathing: volcanologists have been tracking the movement of magma under the park and have calculated that in parts of Yellowstone the ground has risen over seventy centimetres this century. Is this just the harmless movement of lava, flowing from one part of the reservoir to another? Or does it presage something much more sinister, a pressurised build-up of molten lava?

Scientists have very few answers, but they do know that the impact of a Yellowstone eruption is terrifying to comprehend. Huge areas of the USA would be destroyed, the US economy would probably collapse, and thousands might die.

The WorldAnd it would devastate the planet. Climatologists now know that Toba blasted so much ash and sulphur dioxide into the stratosphere that it blocked out the sun, causing the Earth's temperature to plummet. Some geneticists now believe that this had a catastrophic effect on human life, possibly reducing the population on Earth to just a few thousand people. Mankind was pushed to the edge of extinction... and it could happen again.

Frightening, isn't it?

[Viking]

Yeah, I saw the recent BBC documentaries about it. Frightening indeed, but it`s not likely to happen in our lifetime so it shouldn`t be anything to worry about, yet.

[Ldvs]

Scientists aren't that optimistic. They say it can happen anytime now, tomorrow or in 10,000 years.

[English assassin]

I think we have to distinguish between things that are frightening and that we can't possibly do anything about, and things that are frightening that we could change.

There's so many of the second to worry about its hard to have any worry left over for the first.

Am I stupid, or does this fall into the catagory we can do something about? Drilling down to the magma chamber to relieve pressure. Course, it would be very expensive so much so that it would certainly be better to spend it on more certain/near term problems so I guess it's just a nitpick.

[Ldvs]

Unless you want to make everything explode I doubt drilling would be a good idea. Assassin is true here. Scientists are clear about that: they can't do anything but monitor and evacuate civilians when it's about to erupt.

[Steppe Merc]

To attempt and drill for an reason in Yellowstone would be unecaptalbe for the animal population there. Why don't we just drain the ocean to prevent giant tsunami, for goodness sakes?

What we have to do is fix what we've broken, not what is natrual.

[BDC]

Scary, and absolutely nothing can be done about it. An Act Of God really. Hehe.

[Goofball]

Since Yellowstone Park is quite plainly concealing a weapon of mass destruction, I think Bush should send in a couple of hundred thousand troops to kick a little Yogi Bear ass...

[Kanamori]

Wait until Redleg gets back, though.

[Gawain of Orkeny]

Ive posted this twice already. Its pretty old news.

The Americans and Canadians here probably are more aware than us Europeans, that Yellowstone, the renown national park, is also a potential disaster for humankind.

Yellowstone was allowed to become dangerous during the Clinton Administration, when efforts to address the issue were limited to a tactical airstrike on the Grand Canyon, made in an attempt to divert attention from the Lewinski affair.

The Bush administration intends to do the right thing to bring this dangerous threat under control. Several suspicious boulders from the Park are being held indefinitely at Camp Geo on an unidentified island off the coast of Zanzibar.

There are plans to release the pressure by drilling in and around the area and remove potentially dangerous oil, gas, water, and other minerals. Bush spokespersons deny that this is actually a cover for mining, saying that this is being done in the name of national security.

Additionally, in order to ensure that should the super-volcano explode the government can quickly recover and stabilize the country, all Americans are being required to submit DNA that will be encoded onto a lava-proof card, and defense installations are being outfitted with multi-million dollar ash/ember/smoke/flaming gas screens,currently being produced by Halliburton.

At this time research scientists working at a super-secret lab in Nevada are attmepting to find a way to speed up continental drift, in the hopes that the hotspot can be relocated to Mexico, or maybe France.

Yikes... Armageddon....

I think we need sanctions. ~D

Very good!

When it happens, I have the comfort in knowing those who die in the blast will probably never know what hit em'. Much like a nuclear strike, you will just be vaporized, probably painlessly. Those people living far from the area, I would fear, would die much more horribly, probably from starvation.

Not vaporized, unless you're standing just above the crater. They'll be incinerated instantaneously when the "ground-hugging" flows of volcanic ash hit them. Those who live far from the area will either die from starvation (lost harvests because of permanent snow falls) or be intoxicated by the ash rains.

Bis repetita placent.

Now that would be extremely cool

[Viking]

Really?

Perhaps if you live on the Moon with access to satellite-tv.

[Ldvs]

Now that would be extremely cool
Cool is the right word, considering scientists calculated that temperatures would plummet by 12°C (53.60 degrees Fahrenheit), with almost permanent snow falls spelling disaster for harvests ~;)

[Kagemusha]

We all die eventually.... :bow:

Lvds, no offense, but a 'delta' of 12C is not 53F. Absolute 12C is 53F, but you only add the 32F offset to get an absolute temperature reading. One degree Celcius is 9/5 (roughly 2) degrees Fahrenheit. The global climate would drop a still frosty 24F. The high temperature in Death Valley would only be in the 80s. LA would average highs of 55. Winter in Boston would see months of weather never getting above 0F.

That being said, I'm in EA's boat. Yeah, an asteroid might strike the planet at any moment. But what the hell am I going to do about it?

Funny post Ichi, I got a hoot out of that.

[Evil_Maniac From Mars]

Ask little Georgie to nuke it.

No offense taken ~;) As I never use Fahrenheit degrees, I converted thanks to a degree converter found on Internet. I just wanted to give the equivalent for the English/Americans but obviously it didn't help ~D

Huge areas of the USA would be destroyed, the US economy would probably collapse, and thousands might die.

[…] And it would devastate the planet. I love when journalists attempt to soften the blow by understating the projected casualty figures.

We are talking about a global disaster here on the same scale as an hypothetical collision with a small asteroid and “thousands might die.”

[Redleg]

the area is still the best lookin part of the World - no matter how dangerous it might have the potential to be.

In Highschool I did a Volcanology Class for a Semester, it was very interesting. One theory on the matter pertaining to Yellowstone is that it's gonna blow pretty soon in a Cosmic Sense (1 Day to 1000 years is pretty short). However, it is also seems that throughout history the hotspot of Magma underneath Yellowstone Park is moving west (veeerry slowly moving west), While the hotspot is in the throws of movement it has never been known to erupt, its when it hits a snag in the earths crust, it builds up pressure and explodes (such as Yellowstone Park). Previous to Yellowstone Park, the very same hotspot is what scientists some scientists believe to have been Yosemite Nat'l Park in California. Another similar hotspot is underneath the Hawaiin Islands, and as one can tell, the Islands are not connected, so while it is on the move, nothing seems to happen. So if the same can be said of the Yellowstone Hotspot (which is moving) it could be much longer than 1000 years for it to erupt. Some Volcanologists aren't sure weather the hotspot will erupt in Yellowstone again, or elsewhere, but when it happens, it will probably have the same affect.
