Posted on 03/10/2007 8:19:17 AM PST by aculeus
Researchers at Rensselaer Polytechnic Institute have discovered what likely triggered the eruption of a "supervolcano" that coated much of the western half of the United States with ash fallout 760,000 years ago.
Using a new technique developed at Rensselaer, the team determined that there was a massive injection of hot magma underneath the surface of what is now the Long Valley Caldera in California some time within 100 years of the gigantic volcanos eruption. The findings suggest that this introduction of hot melt led to the immense eruption that formed one of the worlds largest volcanic craters or calderas.
The research, which is featured in the March 2007 edition of the journal Geology, sheds light on what causes these large-scale, explosive eruptions, and it could help geologists develop methods to predict such eruptions in the future, according to David Wark, research professor of earth and environmental sciences at Rensselaer and lead author of the paper.
The 20-mile-long Long Valley Caldera was created when the supervolcano erupted. The geologists focused their efforts on Bishop Tuff, an expanse of rock that was built up as the hot ash cooled following the eruption. The researchers studied the distribution of titanium in quartz crystals in samples taken from Bishop Tuff.
A team from Rensselaer previously discovered that trace levels of titanium can be analyzed to determine the temperature at which the quartz crystallized. By monitoring titanium, Wark and his colleagues confirmed that the outer rims of the quartz had formed at a much hotter temperature than the crystal interiors. The researchers concluded that after the interiors of the quartz crystals had grown, the magma system was "recharged" with an injection of fresh, hot melt. This caused the quartz to partly dissolve, before starting to crystallize again at a much higher temperature.

I'm selling Supervolcano Eruption credits. They are currently going for $10.00 a credit. Who wants to buy some?
I'm trying to capture the market on 'super volcano insurance.' If one erupts, I'll be right there, trust me.
Sell 'em to yourself, a la Algore.
Ok, when the Yellowstone caldera erupts, I'll give you a call.
So, what they are saying is that a build up of MAGMA causes a volcano to erupt. NOW WHO WOULD HAVE EVER SUSPECTED THAT!!!!
This is a conservative website where we extol the virtues of a market economy. My Supervolcano Eruption credits are available for purchase at $9.75 a credit, and I'll give a 10% discount for every 100 credits purchased.
All I have to do is get my website up, and I'm ready for bidness.
This sort of eruption is now forbidden by EPA regulations, thank goodness.
Come on FRiend. Let's set up a Corporation.
This sucker goes off again it will make one huge carbon footprint, NO? LOL!
LOL!!! Sounds good to me. Texas has a 4.5% corporate income (franchise) tax. What's the cost of doing business in Alaska?
"So, what they are saying is that a build up of MAGMA causes a volcano to erupt. NOW WHO WOULD HAVE EVER SUSPECTED THAT!!!!"
Yeah, everybody knows that Republican greed causes volcanoes to erupt.
That's what I was thinking. Looks like another case for CAPTAIN OBVIOUS!!
Thanks for that bit of info, I will sleep much better tonight : )

Does that mean that all credits are free after 1000 are purchased?
About 4 years ago a Richter 5 hit the pluton below Yellowstone. Long dormant geysers are coming back to life again, big time. Yellowstone Lake is being rapidly pushed out of its bed, to the south. The land is rising by (measured)millimeters month by month.
Yellowstone erupts every 600,000 years on the average, and it's been 630,000 years since the last major eruption, although there have been some 30 minor eruptions in the interval. So it's looking more and more like a NATURAL nuclear winter will not only cover the midwest bread basket with ash, but take out 99+% of the human race as well.
This has happened before of course. The tabu(sp?)supervolcano in indonesia 74,000 years ago almost completely wiped out homo sapien, it shows up in our mitochrondial DNA : between 70,000 and 80,000 years ago the population was reduced to just 200-400 individuals(it was that close to extinction for us).
DefSec Cohen referred to the scalar beam weapon that can cause earthquakes as well as weather control(like steering hurricanes ala katrina). The Yakusa(japanese mafia)were supposedly involved with the rented russian SBW which caused the Richter 5 Yellowstone Quake. Sounds far out, yes? How often is truth stranger than fiction?
I can die peacefully now.
LOL! If that's what it takes to get Walmart out of the picture, so be it! I still make at least $4000 on the deal, and my cost of sales is zilch, so I'm ok.
Where I'll make the big bucks is infomercials on TV, just like Carleton Sheets.
I've read that the group which set off the Tokyo sarin gas attack used the SBW to set off the Kyoto earthquake.
I wanted to live in Bishop...mama said no. Too many volcanoes.
Y'gotta' love the Internet. All of the world's libraries within reach of your den.
yep! I know what happen 760,000 years ago...........
I also have global warming jackets...
If only we knew what was in those burned libraries...
I was watching a show about the Yellowstone supervolcano once, though, and I remember one scientist saying that it was unlikely to ever happen again with the same magnitude because the area of magma under Yellowstone has been moving for years, albeit slowly, and will be partly under the mountains after a while, and will be less likely to erupt with the same force because it won't be under a relatively thinner area of crust. Don't know, but it sounds plausible.
We were at Yellowstone back in 2003, when they had to close some areas because they were overheating. The map of the park shows, with a dotted line, the outline of the caldera, but you don't need that to know when you've crossed the line. The land changes, and you see what looks like chalky or salty areas along with the fumeroles continually bleeding steam into the air above ground. It is truly a sight to behold!
That picture is a very good graphic display of what a super volcano is compared to a "regular" volcano.
Tuba sounds better, a BIG BLAST from the biggest HORN in the band.
Do you remember the Mount Saint Helens eruption in 1980? That shut down the Pacific NorthWest for 7-10 days, remember it well. These things HAPPEN, the question is the RATE, how MUCH volcanic dust is injected into the stratosphere for it to subsequently settle out over the ensuing 3-4 years. Do you remember the golden/yellow hue of the atmosphere after the Mount Pinatubo eruption?
Yellowstone is showing all the signs of an eruption with the increased activity and rising land/earthquakes. All it takes is a crack from the surface to the pluton magma chamber 5 miles down....is this the "wormwood" mentioned in the book of revelation, and the subsequent three and a half years of nuclear winter darkness that follows.
On the one hand is the "it never happens to ME" crowd and on the other hand is may 1980...
Could be. Ironically one of the guys in our singing group on waikiki beach was Yoshi from Kobe, a real super guy. It's scary that we are developing technology like the scalar beam weapon and it finds its way into criminal hands, the co-ordinated attack of 911 being a prime example.
As you read up on this on the cheniere.org website you can then download satellite photos and SEE the carpenter's square(L shaped)clouds that indicate this SBW in action.
So what to do? The US trying to defend, as the world cop, everyone everywhere...or a satanic world wide police state...or a UN that is more than oil-for-food crooks taking bribes, a REAL democratic organization...or Jesus returning to WHACK the bad guys...what's the answer?
Toba(tuba) was 6,000 times bigger.
I'm not saying that the Yellowstone supervolcano will not explode again, I'm just saying that it may not be quite as bad as the last one was, because of the supposed movement of the magma chamber. Even an eruption 1/4th the size of the previous one would put a lot of people in a world of hurt for a long time!
But it makes life more exciting!
P.S. That photo doesn't look like the Bishop Tuff I've seen.
760,000 years ago.
Even a minor eruption would take out our midwest bread basket, how much in the way of canned goods have you got stored up?
Hellava TUBA blast, yes? Reminds one of the UFO TUBA blast in the movie CLOSE ENCOUNTERS that shattered the glass in the tower on the set....
Great movie, some was filmed in my backyard:
Didn't know that about film sets/locations for CLOSE ENCOUNTERS. If you've ever actually been there at the devils tower you know how SMALL it is, and just an asphalt walkway around it. My father was born in Hulitt, WY; just a stone's throw away. There is another similar volcanic spire in the area but it isn't as prominent as the devil's tower.
I never saw that one, either; but when I found it, it looked so perfect...
He was very dubious, but my impression was that his doubts were not about the possibilities, but the likelihood that they had been developed and tested.
I retain an open mind.
Where did SecDef Cohen make those remarks about scalar weapons ?
