Yellowstone Park Volcano Set To Erupt Wiping Out 2/3 Of U.S.

[nebula]

the question is jade, did the earthquake actually set it off, or did the magma under the surface cause the quake, and then the eruption? It all goes back to, if magma is going up, it has to displace something, and when it displaces stuff, it can cause earthquakes-which is why many people think there is a volcano under Yellowstone, they think magma is rising up and pushing the earth, causing earthquakes. What their not taking into consideration is water can do the same thing.

So, what is moving the water?

[The_Patriot21]

That is a good question nebula-Im not sure. a couple of the articles I pointed out think that water is draining down to an underground lake from yellowstone lake-with that being said, I don't know. Unlike national Geographic, Im not afraid to admit I don't know something.

Umm...I thought the magma activity of the volcano causes the earthquakes - not the earthquakes that cause the eruption.

They are taking a working theory-keyword here is theory-and presenting it as fact, when it is only theory. If your familiar with proper scientific process, then you know theory is not fact, and it annoys me, when scientists go through, and present "theory" as fact when it is not, and I think people should learn the difference themselves.

Hmmm.. Well to be more precise earthquakes are cause by pressure build up, which can be caused by magma forcing it's way up through the crust of the earth. However, not all earthquakes are caused by volcanic activity, pressure caused by the shifting of the plates in the earths mantel, gas build up and in same cases loss of pressure holding a void up. The pumping of high pressure water into the earth to remove oil, gas, ect, does cause small amounts of shifting of local rock. There is also the fact that with a big enough earthquake one could get magma flow if a deep crust break were to happen, along the ring of fire area.

The volcano under Yellowstone is not a theory, it is a fact, (http://volcanoes.usgs.gov/observatories/yvo/index.html) the theory part comes into play when man tries to explain what will happen if it blows up. The instruments used to measure the movement of the ground around a caldera can give us an idea, but, we do not know for sure. I have stood on the edge of erupting volcanoes (Kilauea, Mauna Loa and Lo`ihi) looking down into lava pockets and taking pictures of the flow, and was knocked to the ground when a large bubble hit topside.

old shep, in those two links, I see no actual proof that there is a volcano under yellowstone-all their showing is seismic activity and that its heating up, which can be caused by other sources. So like Ive been saying all along, its theory, not fact. Going through them theres strong evidence it was a volcano at some point-but theres no proof that its still a volcano. So I still stand with the theory, not fact. Those articles really arnt all that descriptive, their just saying hey look, we got satillite images, and its heating up, it must be a volcano. Well, anyone can say that, I can take thermal images of NYC with a sattillite, and if its warmer then last year, then it must be a volcano.

Yellow and orange ovals show volcanic centers where the hotspot produced one or more caldera eruptions- essentially "ancient Yellowstones"- during the time periods indicated. As North America drifted southwest over the hotspot, the volcanism progressed northeast, beginning in northern Nevada and southeast Oregon 16.5 million years ago and reaching Yellowstone National Park 2 million years ago. A bow-wave or parabola-shaped zone of mountains (browns and tans) and earthquakes (red dots) surrounds the low elevations (greens) of the seismically quiet Snake River Plain. The greater Yellowstone "geoecosystem" is outlined in blue. Faults are in black.

Thre are many many small earthquakes at yellowstone every day..... The ground, especially the floor of the lake moves up and down. The magma chamber under yellowstone is very large and in some places is only 5 miles below the surface. Because of all the ground activity and the gas vents, the ground water flows close to the mosten rock and super heats which causes the steam to rise and blow water out of the giesers.

It is not a conventional volcanoe in that it has no cone that was formed, largely because it was so huge that it blew itself away. It has had several flows since the last big eruption that you can trace. It sets above one of the largest hot spots in the world as I remember the programs I've seen both at Yellowstone and documentaries on both TV and the internet.

i did find some interesting things on this site about yellowstone.... http://all-geo.org/highlyallochthonous/2010/08/yellowstone-where-did-all-the-ash-go/ including some maps showing tuffs of ash spread around the country. You might find it interesting.

Patriot - It is a bit puzzling that you are so adamantly against the concept of Yellowstone being the caldera of an active volcano. OK, sure it is "just a theory" - but so is our understanding of the layers of the earth down to its core, so are the nature of black holes, so are lots of other things we act upon as "fact".

Granted, the whole hype about "it can blow any minute" is majorly annoying.

And yes, tagging the cause of the symptoms occurring as established fact when we have limited information, relatively speaking, to go on, is improper reporting.

But do you have sufficient evidence to claim that the "hot spot" is no longer active?

[The_Patriot21]

Im not against it nebula-again let me emphasize this, I dont necessary think its not. They have a strong case for it being a volcano, and Im not saying its not, what Im saying is the evidence they have for it is inconclusive, and theres a strong possibility its not. What Im against, is them teaching something that is in the theory stage-as fact, thats what Im against. Theres a difference between "scientists believe there to be a volcano underneath" yellowstone, which would be a true statement-and one I would agree with-because it admits thats what they believe-thats their theory, and unproven yet-and "there is a volcano under yellowstone" which is, unproven, and therefore conjecture, and Im against.

The site that I posted has a map of a layer of ash across many states that thas been chemically matched with matching material that came out of Yellowstone.

It took a pretty big blow to scatter ash over that amount of area.

So this range is from the past erruption of thousands of years ago ?

I thought those maps were for ...when it would errupt again..

I thought I was o.k. ...here in La.

The one now is a supervolcano ...so National Geo. says.
