Yellowstone Super-Eruption Threat Debunked

GennyCream writes "The Internet has been all a-buzz with tin-foil-hat geeks have been in a tizzy over supposed government coverups of a soon-to-come super eruption in Yellowstone (especially see The Shadow Confederacy, but also Rense.com, or BlackVault for entertaining examples). I found an article on ATSNN.com (the Above Top Secret News Network) that cut the paranoia with the proverbial knife and went straight to the source. Their interview with USGS Yellowstone scientists covers all the angles and should inspire the mad-hatters to find something else to fear (for now)."

    What I don't understand is why anyone who suggests something like the government covering up a disaster or questioning something like the moon landings is immediately ridiculed. There is precedent for such a thing, particularly in the case of near Earth asteroids. In an effort not to alarm the public and to prevent the media from distorting the facts, things are covered up while examined and studied. Stuff like this is plausible and questions need to be asked. If the events such as the seismic activity are still being studied, and nothing is being said to keep the story away from the media, certainly one interview with a member of the USGS isn't going to change things.

    My point is this: why is it so bad to ask these questions? We're perfectly willing to believe conspiracies between SCO and Microsoft but we accept the government at face value on things such as this and ridicule the doubters? Why is this?

    I'm not trying to start a flame war, but I'm genuinely curious why we take such negative attitudes toward questions such as whether the government doesn't yet want to inform the public over seismic concerns in the Yellowstone area. I'll probably get modded down, but I'd like to know.

    I pretty much hold with the crowd that predicts massive volcanic eruptions, shifting of plates, the erosion of entire mountain ranges, massive glaciation, massive floods...big canyons being carved in deserts, cities sinking under the ocean, deserts turning to forests, forests turning to desert and every single thing you can imagine.

    The sad thing is that I only get to live a human life span and will miss most of it.

    BTW, there is a hot spot under Yellowstone and big cinder cones and a lot of lave flows in Idaho. I think there is a better than average changes of some major event in a short geological time frame.

      Oh, there absolutely is, and its a whopper. What do you think is driving all the geysers? The real issue this poster was raising however was a more discrete event in the predictable near future, thus my post. At some point, the magma chamber may indeed break through, but there is no advanced knowledge of when that is going to be and certainly no conspiracy.

  3. Bias and Progress? by core+plexus · · Score: 5, Interesting
    I'm an exploration geologist, and have experience with many facets of geoscience, such as geochemistry, geophysics, and other fields (excuse the pun).

    One thing I have encountered is the bias, whereby someone is so in love with a theory that they are blind to the fair maden that comes along later. It's hard to let go of the comfortable setup you have built over the years, and when some fresh outsider comes along and tells you different, it gets the blood boiling.

    I have encountered this with grizzled old prospectors who were positive they had found the next Sudbury or Ft. Knox, as well as 'cultured, educated' folks who have spent most of their time in the drawing room discussing theory. I have found numerous rich deposits, but due to economics, politics, or other obstacles, most shall remain ummined for now. In most cases, I dispensed with current trends and went back to the old stuff.

    Too often, someone will arrive at a "conclusion" that might look good at the time, but prove to be very wrong later. So what? Someone has to get it wrong. But one has to be able to release that burning stick.

    The Earth has many very serious events in its' past. We can expect more, and we have truly been living in a period of relative peacefulness. I've been to Yellowstone many times, and know what it is like to slip into a pool heated by the Earth, while Elk and Bison graze nearby. Been to Crater Lake, too. Now THAT was a big ol explosion, but it happened way before I got there. I've been in 3 volcanic eruptions, 2 in Alaska. It's quite exciting. One time I raced an oncoming cloud of ash.

    Funny, but when I read this I thought of the people I read of near Mt. St. Helens, and some friends I had in the Phillipines.

      Another of the biggies was reported to be Lake Taupo in New Zealand. As well as having one of the largest (I think the 26.5ka Oruanui event has been estimated at 800 cubic km). The more recent eruption around 181AD was only about 50 cubic km, but is estimated to be one of the most violent eruptions.

      They have found metres of deposits from Taupo in Auckland which is over 250km away. One of the field trips we did on the Cities on Volcanoes 2 conference in Auckland in 2001, took us to Tamaki in Auckland where we could see around 6m worth of deposit from one Taupo eruption. I think it was this eruption that has been linked to the Chinese noticing changes in their sunsets.

  4. Don't forget the "classic" BBC supervolcano report by alienmole · · Score: 5, Interesting
    Here's the BBC documentary on supervolcanoes. The link to the transcript is at the bottom of the page.

    The interview above simply debunks the idea that there are currently any clues that an eruption is imminent (although much of it seemed to say "we're not measuring that"). However, there really is a giant magma chamber under Yellowstone, and if it ever breached in the right (or wrong) way, the continental US would be toast, and the rest of the planet would experience a nuclear winter style scenario.

    Depending on how you project the historical numbers, we may already be overdue for the next eruption. Then again, the margin for error is measured in millenia, so it's a little like the major asteroid strike scenario: it could happen anytime, but it probably won't.

  5. Long Valley Caldera by Mahonrimoriancumer · · Score: 5, Interesting
    I think it is funny how many people are obsessed with the volcanic activity in Yellowstone but completely ignore the Long Valley Caldera. From the USGS website:
    Earthquake activity in the Long Valley area of eastern California increased greatly after 1978. ... Since 1980, typical background geologic activity in the Long Valley area has included as many as 20 earthquakes of magnitude 2 or smaller a day, occasional swarms of magnitude 3 and larger earthquakes (felt locally), and uplift of the center of Long Valley Caldera at a rate of about 1 inch per year. Swarms including magnitude 4 earthquakes may occur about once a year.

    This past semester in my geology class we did an in depth study about volcanos and this caldera in particular. My professor has a great deal of enthusiasm about this supervolcano because it is most likely going to erupt within the next 50-100 years.

      Yes, but the caldera itself isn't very likely to erupt. What you would get is a relatively small (as far as volcanic eruptions go) eruption at Mammoth Mountain or at one of the craters in a chain that runs to the north.

      Volcanic activity has occured there within the last 600 years or so as well. Just take a short drive up 395 to Obsidian Dome. That pile of obsidian wasn't there 600 years ago! What is actually interesting is that you can sit on top of Obsidian Dome and look north towards Mono Lake and you will see a series of similiar looking hills that form the Mono-Inyo Craters.

      There is a lot of evidence that there is magma beneath the ground. From various earthquake swarms, to the hot springs towards the south to the treekill at Horseshow Lake.

      Anyway, check out the USGS's outlook on the Long Valley Caldera and also browse around the .

    My point is this: why is it so bad to ask these questions?

    I don't think it's bad to ask the questions. However, when people start constructing massive theories based on scant evidence and then cling to them madly, that's a different matter.

    Scientists are smart people, and many of them are happy to answer questions from people who don't specialize in that area. It can be frustrating, though, when one of those people is dead set on believing something that is completely crazy.

    For comparison, I went to a lecture by Brian Greene (author of The Elegant Universe) last night. He's a very, very smart guy, but he is also good at explaining things like quantum mechanics and string theory to non-physicists like me.

    At the end of the lecture, there was a question and answer session.

    One of the people asked a lengthy question about similarities between the language of mysticism (the "word of God" and the vibrational jibber-jabber that some people are into now) and that of advanced physics (e.g. string theory and the idea that all particles are actually the result of vibrations). He was obviously a misguided UFO guy, but because he asked the question in an open-minded way, Greene was able to turn it into an interesting topic.

    Later, a woman came to the microphone and started off by accusing him of being biased towards "European mathematics," and that if he's interested in the higher dimensions that string theory predicts, he should be investigating the Africans who can enter the fifth dimension and that Einstein was looking for some Buddhist chant that would function as a unified theory. Because she was dead set in her crazy ways, he couldn't turn it into an interesting discussion and basically had to just tell her she was wrong.

    Page for that is here, thanks for reminding me.

    "North Pacific and Russian Far East air routes (gray lines) pass over or near more than a hundred potentially active volcanoes (red triangles). Aircraft flying along these routes, some of the busiest in the world, carry more than 10,000 passengers and millions of dollars of cargo each day to and from Asia, North America, and Europe. In the North Pacific region, several explosive eruptions occur every year. Ash from these eruptions, which has caused jet engines to fail, is usually blown to the east and northeast, directly across the air routes."

    And here's what happened to one 747: "As the crew of KLM Flight 867 struggled to restart the plane's engines, "smoke" and a strong odor of sulfur filled the cockpit and cabin. For five long minutes the powerless 747 jetliner, bound for Anchorage, Alaska, with 231 terrified passengers aboard, fell in silence toward the rugged, snow-covered Talkeetna Mountains (7,000 to 11,000 feet high). All four engines had flamed out when the aircraft inadvertently entered a cloud of ash blown from erupting Redoubt Volcano, 150 miles away. The volcano had begun erupting 10 hours earlier on that morning of December 15, 1989. Only after the crippled jet had dropped from an altitude of 27,900 feet to 13,300 feet (a fall of more than 2 miles) was the crew able to restart all engines and land the plane safely at Anchorage. The plane required $80 million in repairs, including the replacement of all four damaged engines."

    Maybe when the asteroid hits it. Of which there is also certainly a chance.

    The numbers game is different from the 'chances of asteroids hitting'. Let me explain, (following numbers are just for example, but you get the idea) Chances of been hit by asteroid.
    Year 1 - 0.0000001 %
    Year 2 - 0.0000001 %
    Year 3 - 0.0000001 %

    Year 3 - 0.0000003 %
    ...
    Year 9999 - 0.0009999 %

    The difference between Yellowstone going up in smoke, and an asteroid, is that the chances of erruption increase each year an erruption hasn't occured, due to the previous years magma adding to the pressure. Eventually, the chances will become large enough that it will be more lightly to happen than not. As opposed to the asteroid hitting, that might happen, but probably not... and also not subject to the previous years non-event effecting this years chances.
