- aknowles5139, on 10/12/2007, -1/+38Youtube link of the video:
http://www.youtube.com/watch?v=P6mVOgLK9IA - undersky, on 10/12/2007, -1/+31an actually well written geological article not about Wii or Apple got to front page? hell must have frozen tonight
- Wisgary, on 10/12/2007, -0/+29I disagree about the apple thing.
"On their first clear day, Steinmetz and Bill McIntosh, also of New Mexico Tech, rode snowmobiles up to the crater's rim." - skywake, on 10/12/2007, -0/+18it tastes like burning.....
- Lean, on 10/12/2007, -1/+18I guess it's bad that I had no idea there was a volcano in Antarctica?
- IEatEmoKids, on 10/12/2007, -6/+21Now we're gunna have people saying this is from global warming.
- CRasH180, on 10/12/2007, -1/+15I I never thought I would see blue lava. This video is amazing to see. Dugg!
- Canada4Life, on 10/12/2007, -0/+13That lava looks like flubber.
- BrainInAJar, on 10/12/2007, -0/+13"More likely a colour swap."
Or even more likely, a digital optical sensor picking up infra-red radiation. Try shooting a tv remote at a webcam, it'll flash blue as well - nocturne, on 10/12/2007, -0/+13direct link to video:
http://www.smithsonianmagazine.com/media/2006/video/volcano_erebus-small.mov - megaloid, on 10/12/2007, -0/+10And feels like fire.
- NSMike, on 10/12/2007, -1/+10Yes, this is from global warming. The INTERNAL kind.
- zim312, on 10/12/2007, -0/+8The Antarctic MX4, one of the most advanced surveillance cameras in the world, has enhanced optical sensitivity to volcanic phenomena, making it highly specialized for viewing active lava lakes. Incorporating infrared filtering technology, the Antarctic MX4 produces images in which lava lakes appear to glow electric blue. The resulting images allow volcanologists to observe lava circulation, explosion details and distribution of lava cooling bombs.
- Fhionnlaoch, on 10/12/2007, -0/+7Well, my personal observations are worth null, but I find that a lot of the sciency articles tend to appear around 11pm-2am PST. It's tends to be good time to be on digg.
- Canada4Life, on 10/12/2007, -0/+6Fanboys gone wild!
- autodata, on 10/12/2007, -0/+6It's really disturbing how so many people in the comments here think the lava is actually blue.
- BugMeNot2, on 10/12/2007, -0/+6Good times.
- inactive, on 10/12/2007, -1/+7Anybody know why it's blue?
- Ninjab3ar, on 10/12/2007, -5/+11yeah, and they blame global warming for the icecaps melting off.....
tsk, tsk, tsk Al Gore..... - marinist, on 10/12/2007, -1/+7Blue lava...that's not the typical Hawaii eruption, and somehow fitting for the antarctic.
I looked this up, and this lava cools to a light blue-green rock called phonolite. - Atlantics, on 10/12/2007, -3/+8Bunnies!!!
...nvm digg me down. - Noctem, on 10/12/2007, -0/+5My girlfriend spent 6 months in Antarctica at McMurdo last year (From the end of February to mid-September, their winter), and Mac Town (mcmurdo slang) has a lot of ash all over it from the volcano, and Erebus was constantly spewing smoke. That eruption was friggin' wild, blue lava - Just, wow. She's gonna be upset that she missed this when she sees this video & article - Thanks a million!
- dacheetah, on 10/12/2007, -0/+4As BrainInAJar Suggested, it's just Infrared. Given the way most infrared cameras work, something as hot as lava is going to be about as bright as it can be on the screen, which would likely flood the sensor a little, giving it the blueish tint. With a "normal" visible light camera (or with the naked eye) it would look much the same, but with normal red lava, and probably would be alot harder to see because of the steam and stuff, otherwise they probably wouldn't have bothered using infrared.
- rjpaez, on 10/12/2007, -2/+6someone should mirror this quick (the video)...
- Myztry, on 10/12/2007, -0/+4Of course the lava is blue. How else do they get blue lava for lava lamps :)
- Arkz, on 10/12/2007, -1/+5Blue Lava... or Life Stream... hmmm... i like my idea more
- asurroca, on 10/12/2007, -0/+3Brilliant idea... it will be called... Blue Lava
- KiloCharley, on 10/12/2007, -0/+3 nah, that's just hell pukin' up some bad smurfs
- dacheetah, on 10/12/2007, -0/+3There's a youtube link somewhere on the page....
- dacheetah, on 10/12/2007, -0/+3It's not blue, it's been filmed in infrared (I presume) and as such the colour is basically greyscale, and the blueish colour to it is more accidental than anything else. (Try pointing a remote control at a cheap video camera or webcam, the flashing is usually white, but can go blueish when the sensor is flooded a bit.)
As for copper, it's not really blue at all, it;s a pretty clean green, but it's also only when it's BURNING, as in fire, not melting like lava.
Naked eye (or with a normal colour camera) it would look much like the wikipedia image, white ice/snow, red lava. (Which cools to a blackish rock). - EmileVictor, on 10/12/2007, -3/+6I somehow doubt the lava is blue... More likely a colour swap.
I may be wrong though. I seriously doubt that in any case. - rockets, on 10/12/2007, -0/+3Yes, it is bad. The sad truth is that the likes of you drives the current global-warming political nutscases.
- Suits, on 10/12/2007, -1/+3Second Impact!
- bamapachyderm, on 10/12/2007, -0/+2Mt. Erebus Observatory site:
http://ees.nmt.edu/Geop/mevo/mevo.html - inactive, on 10/12/2007, -0/+2Yes, and the US is responsible for the volcano, with all their consumerism and gas guzzling. For shame...
- SAOSiN, on 10/12/2007, -0/+1i take baths in that stuff!
- PaulLev, on 10/12/2007, -0/+1Closest we have on this Earth to being on another planet. http://paullevinson.blogspot.com/2007/01/not-snakes-chronology-protection-case.html
- jhshukla, on 10/12/2007, -1/+2copper burns blue-green. but I doubt that the volcano is spewing out copper.
- rowlodge, on 10/12/2007, -0/+1pretty cool, like science fiction...
- Neticule, on 10/12/2007, -4/+5@cloakeddagger
Atleast he will be laughing when he gets incinerated :)
Anything can be a joke! - nazsco, on 10/12/2007, -0/+1that was a rather scientific comment about scientific posts on digg.
- Promantarius, on 10/12/2007, -0/+1It's probably just an altered video, or a video that wasn't captured via the standard means (intense heat gains colour, etc.) I don't know for certain, but I'm fairly sure lava is usually red due to the heat which rules out most alternatives (I don't think rocks and metal turn blue as they burn?)
- UCFMark, on 10/12/2007, -0/+1I'm pretty sure it's not blue. Take a look at this picture on Wikipedia: http://en.wikipedia.org/wiki/Image:Erebus_Lava_Lake.jpg
It shows the lava lake of Mount Erebus and the lava is clearly red. - dacheetah, on 10/12/2007, -0/+1You don't need a hazmat suit unless your getting close enough that it gets too hot, if you want to be comfortable, you would have to be at the point where you are not too close to the lava, but not far enough into the cold to freeze, and from there, there is little need for the hazmat suit, although you'd probably have to keep turning around, or your back will freeze, and your front will burn...
- osakaguy, on 10/12/2007, -0/+1Hot lava death!
- shortarabguy, on 10/12/2007, -0/+1"Though they grow or shrink depending on how much heat the volcano emits, inside they maintain a temperature of about 32 degrees."
That's Celsius, right...? - dacheetah, on 10/12/2007, -0/+1They said warm, so I presume so. Compared to the rest of Antarctica, 32 degrees F is pretty warm, but I still think it sounds more like celcius. Certainly not Kelvin... 32 degrees K is damn cold...
- technonoob, on 10/12/2007, -1/+2um old news..... 12-18-05
- EvilDr.X, on 10/12/2007, -6/+7Because it's cold in Antarctica? Duh.
