Yellowstone National Park's supervolcano just took a deep "breath," causing miles of ground to rise dramatically, scientists
Nature Wallpaper Midway Geyser Grand Prismatic Yellowstone
The simmering volcano has produced major eruptions—each a thousand times more powerful than Mount St. Helens's 1980 eruption—three times in
the past 2.1 million years. Yellowstone's caldera, which covers a 25- by 37-mile (40- by 60-kilometer) swath of Wyoming, is an ancient crater formed
after the last big blast, some 640,000 years ago.
Since then, about 30 smaller eruptions—including one as recent as 70,000 years ago—have
filled the caldera with lava and ash, producing the relatively flat landscape we see today.
Still, since the start of the swelling, ground
levels over the volcano have been raised by as much as 10 inches (25 centimeters) in places. "It's an extraordinary uplift, because it covers such a
large area and the rates are so high," said the University of Utah's Bob Smith, a longtime expert in Yellowstone's volcanism.
Yellowstone rises and falls all the time, it even mentions that in your own link. The 10inch in places rise you speak of has been over time from 2004.
Between 2007 and 2010 the rate of the rising has slowed down dramatically. All again from the link. Basically this news is 3+ years old.
Also check out the yellowstone thread here there is actually good info in that..
Your link seems to debunk your OP more than anything else, you may as well of just stated 'Yellowstone hasn't blown for a long time, it's overdue and
it will be dec 2012'
Fortunately, the surge doesn't seem to herald an imminent catastrophe, Smith said.
"At the beginning we were concerned it could be leading up to an eruption," said Smith, who co-authored a paper on the surge published in the December
3, 2010, edition of Geophysical Research Letters.
"But once we saw [the magma] was at a depth of ten kilometers, we weren't so concerned. If it had been at depths of two or three kilometers [one or
two miles], we'd have been a lot more concerned."
But there are also many examples, including the Yellowstone supervolcano, where it appears the ground has risen and fallen for thousands of years
without an eruption.
When the rate of increase slows, the theory goes, the magma likely moves off horizontally to solidify and cool, allowing the surface to settle back
Based on geologic evidence, Yellowstone has probably seen a continuous cycle of inflation and deflation over the past 15,000 years, and the cycle will
likely continue, Smith said.
It has nothing to do with the recent, normal behaviour of volcanoes. No connection at all.
Don't be so dramatic.
Yeah Yellowstone is cool, been there a few times........ I live in Idaho.
Every time I hear about Earthquakes in California, Floods in the midwest and tornadoes, and hurricanes on the east and southern coasts all I think is
thats why I love Idaho....... then I'm always reminded we live near one of the biggest potential disasters on earth....
If I remember correctly there are only a couple of these on earth. So....... yeah. But if it does go off like they think it has in the past it would
destroy everthing west of it and a lot to the east. Not much I can do besides bend over.
Scientists think a swelling magma reservoir four to six miles (seven to ten kilometers) below the surface is driving the uplift. Fortunately, the
surge doesn't seem to herald an imminent catastrophe, Smith said.
Umm, it looks pretty ok at the moment and the uplift has slowed in recent years. Way to act like tabloid rag and over sensationalise it...
Your title scared me to death - whewww (let's out breath). Interesting article (good to see this didn't just happen all at once today). Seems its
building up to something but scientist seem more relieved then they did at one time. I hope they are right - otherwise, its been great, love you and
see you in the next world.
This news article reminds me of the scene from the movie 2012: Super Volcano Eruption from Yellowstone Park. Everyone remembers the big bulge before
the huge eruption? Check it out (video includes Transformers soundtrack).
However though, History Channel also produced a documentary on a future eruption from the volcano of Yellowstone and recreated what may happen
according to the physics of the explosion. It gives a good idea about the nature of the Park as well as other facts you need to know about the history
of the super volcano.

Moreover, news of this super volcano has been produced and aired in January of 2009 by FOX News. Apparently congress did not want it to be shown on
tv, but after something happened between FOX and congress, the media news source was then able to show their story live on tv. Check it out!!!
Yellowstone Super Volcano about to blow? 1-12-2009
If it erupts, scientists say it's be more powerful than 60 million atom bombs...It could wipe out over 60% of life on Earth...oh, it gets
better...including the entire US continent...

You got me buddy! heart thumpin..and baited breath scanning frantically....with all the hullaballoo about the seisemometers going crazy world wide
today, and this attention grabber i was getting rather wide eyed for a minute....way to go.....heheheheheh
