Just this entry then I'm off to bed. Has anyone else heard of the Yellowstone Supervolcano? Evidently its a somewhat recent finding (the last couple years or so), that periodically in the earth's history there are these things called "supervolcanoes" which erupt. The difference between a regular volcano and a supervolcano is that a normal volcano is a buildup of magma (molten rock) which rises in a column and as a result creates a large mountain until it erupts and leaves a large crater at the top of it. Then it goes through the process of depositing more magma in the crater until it erupts again, and they're all on a schedule (Mt. St. Helens, for example, I seem to recall supposedly erupts every 200 years or so). A supervolcano, on the other hand, instead begins developing a large reservoir of magma beneath the surface of the earth, into a large pool, and as a result does not create a large mountain (which is why the discoveries of supervolcanoes is a recent one). The large reservoir covers a much wider area than a column of magma does, so as a result when one of these erupts they erupt with much greater force, and with much greater destructive results than a normal volcano would. The result of a supervolcano (which usually produces a crater, or caldera, of about the size of Rhode Island, apparently) erupting is that it emits enough ash and debris into the atmosphere as to actually block out the sun, maybe even for years at a time. Supposedly some 74,000 years ago one of these blew and very nearly caused the extinction of man as a result of the "nuclear winter" effect of the debris cloud, limiting the world's population to a few thousand people or so. Ok, so anyway, here is the really worrisome part: Yellowstone National Park in Wyoming contains one of these active supervolcanoes, as recent infrared images from space or something showed. This particular supervolcano supposedly goes off every 600,000 years or so (with a force approximately 2,500 times what Mt. St. Helens was), and by all accounts its been about 640,000 years since it last erupted, making it overdue by 40,00 years. Scientists have predicted that it will erupt sometime in the next 100,000 years, so that makes it worrisome on about the level of the earth being hit by a meteor or something. But consider these ominous signs: in the last century the ground in some areas of Yellowstone have risen over 70 centimeters, in 1975 there was a 6.1 earthquake there, and in 1959 there was a 7.5 earthquake there. A little worrisome anyway, something to file away in the back of your mind. I'll leave you with this quote from Bill McGuire, professor of geohazards at University College London: "There's nowhere to hide from the effects of a supervolcano. When one goes off it will be like a nuclear winter without the radiation."

Posted by: Donny at March 31, 2003 09:41 PMwell....damn. No wonder your mood is sullen.
Posted by: Pam at April 1, 2003 08:46 PMYes, the Yellowstone Super Volcano does exist. Yes, there has been extensive geological activity in the past century in Yellowstone park. Scientists have predicted recently that the Super Volcano will erupt within the next century. Many religeon's predict this eruption to happen in 2012.
Posted by: Cyril at July 8, 2003 09:34 PMBe careful about the facts in the BBC program. For one, the choice of the Lake Toba explosion as the "last" of the supervolcanos seems awfully fortuitous, as Lake Taupo has gone off 28 times in the last 27,000 years:
http://www.wikipedia.org/wiki/Lake_Taupo
The last time it went off in historical times, 181 AD, and its effects were observed by the Romans and the Chinese.
It should also be noted that Yellowstone had an eruption 160,000 years ago as well. The narrators ignored that one.

Posted by: Dave Myers at August 25, 2003 12:02 PMWhat's really interesting about the BBC information is that it was done in 1973 and covered a 50 year span between the measurements. Strangely enough, it's been 30 years and no newer information is available. If, as the 30 year old data suggest, the lava bubble is 10km thick and the land has indeed risen by about half a meter or more in 1973 (probably closer to a meter now), it takes a lot of pressure to move 28,000 cubic kilometers of land up a meter. That's orders of magnitude greater than what a fault moves during an earth quake. Probably something to it.

Posted by: Yams at September 15, 2003 07:19 PMFYI---- yellowstone rangers had to close down parts of the park this summer because of the sudden formation of new geothermal features. Scientists have also discovered this year that a dome is beginning to rise on the floor of yellowstone lake and has already risen 20 feet in the last year alone. the whole park has risen an average of three feet since 1971.
Posted by: Steve at September 17, 2003 12:18 PMApparently, the ground has now started to sink and thermal activity is much greater. Geysers have stopped erupting which causes even greater alarm because the eruption of the geysers allow the supervolcano to breath. This is not happening now.....just a little FYI
Posted by: maewest at October 9, 2003 04:31 PMYeah, that thing definitely worries me. In my opinion, its up there with some biologically engineered superdisease as the most likely thing to wipe us all out.
Posted by: Yams at October 9, 2003 07:24 PMwell super volcanoes do agsist and the yellowstone on will erupt on December 25, 2012 according to the same girl who made the 911 predictions and many more
Posted by: mark at December 4, 2003 03:03 AMThe bottom line is, when Yellowstone goes off again and it will in the not-to-distant future, right now I wouldn't be planning to many vacations in and around Yellowstone Park or better yet, plan any moves to Montana or Wyoming anytime soon....When Yellowstone does finally "Blasts" it's way back into history again, then probably the best thing you or anyone can do for that matter, is to just enjoy the time you have left and remember to leave that day "Blank" on your calendar.
Enjoy,
Norm
Posted by: Norman at December 6, 2003 04:27 PMI live in the middle of North Dakota - the highway to the West of us is cut through a hill .. low in the cut edge are three distinct gray lines .. from the "dust" from the three Yellowstone eruptions.
Oh it will happen again ..
Posted by: Eloise at December 7, 2003 06:51 AMJust a few notes on the supervolcano...
1. The eruption timeclock is hardly regular. There have been two other major eruptions (to my memory) and they were 750,000 years and 600,000 years apart. It's not regular, so don't look at that "40,000 years overdue" claim as significant. It may be 110,000 years UNDERdue.
2. The "bubble" under the lake claim is also misleading. They only noticed it last year, so they have no idea if it has risen, fallen, or remained the same. All they know is the bubble is 20 feet higher than the surrounding lake floor. There has been no measurement of any movement.
3. Moving away from Montana isn't going to do much. The blast zone is figured to be approximatley 1200 miles in radius. Los Angeles is in danger. The death toll would be in the millions.
The bottom line, however, is that we've only just begun measuring this phenomenon. What we see as a "major change" may only be 1% of what is actually going to happen before this thing decides it's time to let off a little steam. And, even if I'm wrong, it isn't going to make a darn bit of difference. Unless you're on the space station, you can pretty much say goodnight. But from up there, it'll be a helluva show.

Posted by: Anthony at December 9, 2003 04:32 AMI hope you're right about it possibly being underdue, cause yeah, from what I've heard too, if it goes it will quite possibly be an Extinction Level Event, even if you're not immediately killed by the blast.
Posted by: Yams at December 9, 2003 01:29 PMI have been doing reasearch on this Supervolcano for the past year and a half; and it seems to me that this thing is getting worse. I have been to the park ,last week as a matter of fact and the supposed "dead-zone" really does exsits.(Scientist dont want to tell you but if this thing does blow anytime in our lifeline then you want it to be sooner than latter,because the longer it waits to explode the worst its going to be. Solar energy from all those huge solar flares we had earlier this year could, from what I have heard feed the volcanos furry. Recent estimates( as of December 19 Have the magma as close as 3/10 of a kilometer from the surface of the Caldera. All it takes for the explosion is a small earthquake to create a fissure to the surface and boom!!!
Posted by: Ken at December 23, 2003 07:13 PMMan, I hope you're wrong about it getting worse. Also, even though the eventual destruction might be less if it goes now, I would be perfectly happy to have it wait another thousand years or so before finally going and taking everyone with it.
Posted by: Yams at December 25, 2003 12:44 AMYUP !!!!!!!!
See Revelations chap. 8 & 9 .........
so some will be left...
Posted by: Lin G...... at January 7, 2004 07:35 PMI agree with Mr. Nuts and I think he is halarious
Posted by: april donaldson at January 8, 2004 08:40 AMwill it be safe in england
Posted by: m at January 13, 2004 01:26 PMIn England you would be safe from the initial eruption and the lava flow, but most reports indicate that if it erupts the earth will be plunged into nuclear winter, thereby killing everyone through starvation as the sun is blotted out because of the ash and smoke that would envelop the planet.
Posted by: Yams at January 13, 2004 03:05 PMI may have the perfect solution!!!. Dig a Large hole in different Danger areas of yellowstone Park, get three powerful nuclar bombs, programme them so that they go off at the same time, Evacuate everyone in the surround ing areas/ states, and no more mr nice guy.
BUT WOULD IT WORK, AND WHAT WOULD HAPPEN, THATS MY THEORY?
Hey ive another genius idea, if the supervolcano erupts or is going to, why dont we dig a massive channel 2-10km wide and 5000 yards deep, send it in three directions avoiding majour cities, the first one will lead to the gulf of mexico, another into the pacific ocean, and the other into lake michigan!
Or if that doesnt work concrete the whole of yellowstone park in concreate 5 yards deep my theory is mould any of these techneques work!!!!
A lot of people have been looking into the Yellowstone caldera events lately. Leading geologists and volcanologists are genuinely concerned about the possibility of an eruption in Yellowstone. One of the geysers there has a history of being dormant for up to 50 years, and it's last eruption was in 1989. In 2003, it erupted three times. The last time this geyser was so active was shortly before the Mt. St. Helens eruption in 1980. For those of us who remember that explosion, to imagine something up to 2,500 times worse is a scary thought.
I'd love to think that the thing is "underdue"; however, the historical signs pointing to an eruption in the imminent future (in geological time) are too many to be ignored. Fish being boiled out of the lake. New mud pots and geysers. Horrid stench of sulphur. Earthquakes whose epicenters are dangerously shallow. Plus much more evidence.
We can hope, we can pray, we can prepare, we can study. But in reality, all we can do is wait.
Posted by: zeal1517 at February 3, 2004 07:10 PMwould there be a supervolcano in europe and could anyone tell me where one may be lurking
Posted by: mshirley at February 27, 2004 12:45 PMThere'supposed to be one under Loch Ness! SEE http://www.lochness.co.uk/exhibition/supervolc.html
Posted by: marky at March 1, 2004 01:28 PMSORRY ABOUT ALL THE POSTS -INTERNET WAS PLAYING UP!
hey ive just had a look at the loch ness supervolcano on the net, it sound pretty bad for me, because i live in a place called york wich is in england,and is only about 6 hours or more drive from where i live, would it effect me if loch ness erupted, cos if it will itl be straigt to dover or any ferry port for me, and far away as posible 
well i live in powell wyoming about 100 miles from yellowstone. being only 16 years old i really dont know much about what is going on but wut i do know is that there has been a lot of dead animals mainly birds showing up which could be natural or west nile. do these animlas prove the volcano had something to do with it? i dont think so. If they have just started studing this thing how do they know how much the ground has accualy risen? anyway if this thing does go off i will be one of these ppl to go with it. so i hope it doesnt go off any time soon. o yea loch ness would effct u but u might not beable to get away.
THE DEAD BIRDS AND SMALL ANIMALS ARE PROBLABLY FROM CO2 METHANE AND OTHER POSIONESS GASSES PERIODICAL RELEASED. lARGER ANIMALS HAVE BEEN KNOW TO DIE AS WELL FROM VOLANIC GASIOUS RELEASES INCLUDING HUMANS
Posted by: JAMES CLARK at September 28, 2004 03:19 PM"We will all go together when we go. Every hottentot and every eskimo..."
I really like the idea of using nukes to set off this supervolcano... if it does work as a 'venting-technique' it'll probably just take out inhabitants of 'Turtle Island' and leave the rest of the Terran Primates to govern themselves.
How about the most effective terrorist plan ever...
...and about digging tunnels: Who's up for the task of digging the hole into the lava-bubble (Poppin' the ballon...)?
>:)
Trying to "pop the bubble" to release the pressure will not work. Releasing the pressure is the problem. There are dissolved gasses in the magma, and releasing a small amount of pressure (by a small fissue or earthquake) can be enough for these gasses to be expand- like bubbles forming when you take the top off a bottle of coke. The expanding of the gasses then all blows up at once.
The magma is not the problem - so digging a canal to the ocean is irrelevant. The problem is the "ejecta" thrown into the sky.
Posted by: Chris at November 16, 2004 06:00 PMI've read everything on super volcanoes and from what I have seen,the yellowstone volcano might go off a little sooner, maybe as early as 2006.
Posted by: Amanda at November 30, 2004 06:19 AMI certainly hope that's not true, otherwise we've all only got a year or two left
