Yellowstone Hot Spot Shreds Ancient Pacific Ocean
jamie passes along this excerpt from DiscoveryNews:
"If you thought the geysers and overblown threat of a supervolcanic eruption in Yellowstone National Park were dramatic, you ain't seen nothing: deep beneath Earth's surface, the hot spot that feeds the park has torn an entire tectonic plate in half. The revelation comes from a new study (abstract) in the journal Geophysical Research Letters that peered into the mantle beneath the Pacific Northwest to see what happens when ancient ocean crust from the Pacific Ocean runs headlong into a churning plume of ultra-hot mantle material."
It's in hot pink, too...or should I wear 3D glasses for that photo?

Please fix the "F you" (no offence taken) with a prefix of I :)
A lot of people don't realize the gulf of mexico was formed by a giant hot spot like yellowstone.
Did anyone else read the headline and think, "Great, another ridiculous claim about the damage being wreaked by wireless network signals"?
What's Kristy Swanson doing these days?
If you were blocking sigs, you wouldn't have to read this.
The author seems to imply that the Columbia River Basalts were generated by the mantle plume, a supposition that isn't in the paper's abstract. Far as I know the jury's still out there. Here's a pdf of a 2007 paper covering the same topic; or, if that won't open for you like it isn't for me at the moment, here's the Google Quick View version.

what a surprise? previously unknown, damning inf., supplied by an average 'joe' (deja boom) no wonder cheney, wolfowitz, blair etc.... have been touting the nuke iran 'solution' AGAIN 24/7, instead of being put on display in glass cages, where they could be observed, so we would not forget what just a little deception/misinformation can cause/allow to happen. see you on the other side of it?
meanwhile (seems like way too long already); the corepirate nazi illuminati is always hunting that patch of red on almost everyones' neck. if they cannot find yours (greed, fear ego etc...) then you can go starve. that's their (slippery/slimy) 'platform' now. see also: http://en.wikipedia.org/wiki/Antisocial_personality_disorder
never a better time to consult with/trust in our creators. the lights are coming up rapidly all over now. see you there?
greed, fear & ego (in any order) are unprecedented evile's primary weapons. those, along with deception & coercion, helps most of us remain (unwittingly?) dependent on its' life0cidal hired goons' agenda. most of our dwindling resources are being squandered on the 'wars', & continuation of the billionerrors stock markup FraUD/pyramid schemes. nobody ever mentions the real long term costs of those debacles in both life & any notion of prosperity for us, or our children. not to mention the abuse of the consciences of those of us who still have one, & the terminal damage to our atmosphere (see also: manufactured 'weather', hot etc...). see you on the other side of it? the lights are coming up all over now. the fairytail is winding down now. let your conscience be your guide. you can be more helpful than you might have imagined. we now have some choices. meanwhile; don't forget to get a little more oxygen on your brain, & look up in the sky from time to time, starting early in the day. there's lots going on up there.
"The current rate of extinction is around 10 to 100 times the usual background level, and has been elevated above the background level since the Pleistocene. The current extinction rate is more rapid than in any other extinction event in earth history, and 50% of species could be extinct by the end of this century. While the role of humans is unclear in the longer-term extinction pattern, it is clear that factors such as deforestation, habitat destruction, hunting, the introduction of non-native species, pollution and climate change have reduced biodiversity profoundly.'

"I think the bottom line is, what kind of a world do you want to leave for your children," Andrew Smith, a professor in the Arizona State University School of Life Sciences, said in a telephone interview. "How impoverished we would be if we lost 25 percent of the world's mammals," said Smith, one of more than 100 co-authors of the report. "Within our lifetime hundreds of species could be lost as a result of our own actions, a frightening sign of what is happening to the ecosystems where they live," added Julia Marton-Lefevre, IUCN director general. "We must now set clear targets for the future to reverse this trend to ensure that our enduring legacy is not to wipe out many of our closest relatives."--

no need to confuse 'religion' with being a spiritual being. our soul purpose here is to care for one another. failing that, we're simply passing through (excess baggage) being distracted/consumed by the guaranteed to fail illusionary trappings of man'kind'. & recently (about 10,000 years ago) it was determined that hoarding & excess by a few, resulted in negative consequences for all.

Perhaps you could fix the Wikipedia article adding that information. Remember, citations are always needed.

Quidnam Latine loqui modo coepi?
I was hoping for a quiet weekend at home, and now it looks like I'll have to deal with an apocalyptic volcano that's going around breaking plates, wearing an ultra hot mantle.
Great.
Am I part of the core demographic for Swedish Fish?
f you too!
Colonization of the Solar System (to begin with) is a prerequisite for human kind to survive major cataclysms on Earth and should be undertaken before it is too late. Even Stephen Hawking endorses such an opinion.
To take an exerpt from the exerpt "f you thought". Yeah f thought. Who thinks anymore.
By the time we can colonize Mars, we can deal with large scale natural catastrophes on earth.
The conditions on Earth after a Yellowstone eruption would still be a lot easier to deal with than the conditions on Mars now.
Of course, by the time we can deal with every imaginable catastrophe on earth, colonizing Mars might become a lot easier than it is now.
If you look at the illustration in the article (and I assume in the original paper, I have access but have to login to a vpn and so on, I will see later since I'm interested), it's quite clear what happened and it's really not what you might think when you hear it "shredded" a tectonic plate. I think what's being implied is that it shredded the plate at the surface, but it happened far underground, in the mantle.
As the subducting plate subducts, it goes down into the mantle and in this case the mantle plume weakened it (by getting into fractures or whatever) and broke it off. So the slab disappears down into the mantle eventually (though these can stick around for years, detached). It's very interesting, but the same thing often happens without being cut off by a mantle plume. It's more or less a guaranteed result in a subduction zone, because the subducting slab isn't strong enough to support its own weight pulling on it after a certain point. Makes absolute sense if you look at a diagram of how subduction works.
Subducting slabs can also be cut off by things like strike-slip faults, which IIRC happened in northern California as a result of the San Andreas (don't quote me on that though). You can see the slabs in the mantle by various imaging techniques.

Considering that they are talking there about ~20 millon years, could be as dramatic as the slow, gradual, taking millon years appearence of a new ocean in the middle of africa. Could eventually lead to a different world? probably. But could lead to catastrophic events per se, in the next i.e. 10000 years ? Don't think so... well, unless the supervolcano there decides to explode pretty soon, and that have any chance to make things even worse.
I think what's being implied is that it shredded the plate at the surface...
Why do you think that? That sounds like the opposite of what the article says. Sounds more like you misread what it said...
"Convictions are more dangerous enemies of truth than lies."
How come places like Iceland are able to tap into this type of energy and Americans barely seem to recognize it? Yellowstone should be tapped.
Subducting slabs can also be cut off by things like strike-slip faults, which IIRC happened in northern California as a result of the San Andreas ...
I'm not sure - I'll have to watch Superman (1978) again and get back to you.
One problem with tapping Yellowstone is that the geothermal fields are almost entirely within Park boundaries. Do keep in mind that the reason for Yellowstone becoming the world's first national park was to preserve it by preventing development.
A Shadeless room is a brighter room.
How this new evidence gives more weight to the Growing Earth Theory. Or maybe they already have taken things like this into account when tracing back the tectonic plate drifts. After all, it has to happen quite often during a few billion years.
