Pyroclastic clouds, the real killers

[dopeyapricot]

First saw this video about 5 years ago. Always thought it was interesting. It has taken me about 5 minutes to find it again. The power of technology :)

[Blue23502]

Shot that would be scary!!!!!!!!!!

[ElliotBrookshaw1]

or even BREATHE!

[thewizardofrhythm]

0:14, worst faked pyroclastic flow ever.

[CRTukker]

@thewizardofrhythm They had to fake that part as they couldnt find a volunteer to run in front of a pyroclastic flow.

[thewizardofrhythm]

@CRTukker I can't imagine why not.

[Buggaton]

@CRTukker best uploader comment ever XD

[belowit035]

@thewizardofrhythm its actually at 0:16

[TNAwrestlingChick89]

scary...

[JOEtheHOTTIE]

it was so hot. before the eruption, those black guys were white.

[TheLastMyztery]

0:16 hahaha

[KeLLeYjO7]

1:52 There's a man standing right next to the eruption....

[pyoujan]

depends on the mountains.... dont know the word...

like this /\ in stead of ,.-''-.,.

understand?

[denver2678]

0:16 FAKE

[Kullg4r]

0:15 lol

[TheNoobwad]

omg i live the way those africans talk!

[inahsa]

@TheNoobwad dude there caribbean.............

[rprince418]

0:16.  Uh, no. That's not happening unless your the Flash.

[SuperSuperMarioMan]

Come on! It's only 2011!

[thevampirediariesftw]

blockens de atmosphere so much.

sorry, i know i shouldn't think that that's funny, but i freaking LOVE jamaicans accents. ahahahahahahahahahah

[Lovecytes]

i know pyroclastic flow is FAST..but is it that fast in the video?

Where is the lava...i tot it supposed to be red in colour... P

[ManDudeYeah]

Fuck pyroclastic flows.

[BillBrd1]

One example where lava is a danger is Mount Nyiragongo in Africa. That volcano has a lava lake in it. The lava is very liquid and when the volcano erupts, it can pour out and travel at quick speeds.

Nyiragongo erupted in 1977 and 2002.

[tooooooommy]

or even BREATHE!!

[masterquadbiker]

@CRTukker some campers did they managed to get away from it in there car

[newchihuahua]

the thing is that many people believe in a volcanic eruption there will be orange, creamy lava. those people should definitely see this video.

[balado1988]

chuck norris walked in a pyroclastic flow and walked out clean

[riceicles123]

@balado1988 Lets face it, he didn't. He was reduced to charcoal almost instantly like any other human.

[quikScOpez7]

Some silly people think that you can just wear a mask and oxygen tank (much like the one's divers wear) + the suit aswell BUT pyroclastic flow is so boiling hot that you'd get boiled alive even with the suit and soon both you and the suit will be burnt alive.

DON'T TRY PUTTING ANYTHING ON! but never give up, run or drive as far away as possible, underground or high up in the air are the best options, otherwise, it's all luck from then on.

[stankado10]

@quikScOpez7 many people have tryd to outrun them with there cars but they just couldnt get far enough..

[evilotto77cheese]

This footage has been sped up - if you look up 'Soufriere Hills eruption' on youtube you can see this same footage at its normal speed

[thaboss32]

better have some serious vtec when that thing comes

[ninerfandave31416]

I don't know, where I'm-a gonna go,

When the volcano blows.

[hebneh]

It bothers me that many of the shots of the actual pyroclastic flows were speeded up. They do move fast, but not that fast in reality.

[CRTukker]

@hebneh 200km p/h is a normal speed for that, some are even far above 200km p/h

[SparkzBE]

@CRTukker Well some books refer to pyroclastic flows which can reach a maximum speed of 650 km/hour, this would've been the max. speed of a pyroclastic flow during the Mount St. Helens eruption

[p3rs0n42]

@CRTukker I literally JUST read a Wikipedia article on pyroclastic flow... checked it's source too and it's legitimate... apparently speeds can be and usually ARE in excess of 400km/h

and with non-fully dilute flow, temperatures can reach and maintain up to 1000 Celsius for 40km

Suddenly volcanoes are more scary....

[pyoujan]

@CRTukker they can reach about 450 miles an hour......

[blahblah4149]

@CRTukker Yah except you couldn't be that close to a flow like that, so they were farther away. Which is slower from far away. So they sped it up.

[CRTukker]

@blahblah4149 i suggest you go check youtube or other sites for the original part, which is also on the exact same speed. Flows do travel that fast. Go look for that part where researchers died while being miles away from the volcano, within seconds after them showing the flow coming down it is already up on them. SO even if you're far away, flows can travel up to 50 miles distance and sometimes even further, so with 200 km p/h (124.7 m/h) and standing on some miles distance, go figure...

[blahblah4149]

@CRTukker I understand what you mean, but scientists know that information. So they shouldn't be that close.

[12OclockLow]

@CRTukker I thought they could be up to ~700km/h. Sounds insane, but that's what I was taught.

[CRTukker]

@12OclockLow Some can indeed, but average speed is around 200 km p/h. And when a flow hits a body of water, then it will even move faster. The heavier pieces will fall into the water, causing a tsunami, and the heat of the ash will evaporate the water, boosting the flow even more which again means that the reach of the flow will be extended enormously.

[blahblah4149]

@hebneh Yeah i know right. But the guy of this video thinks they move that fast from as far away as they are recording.

[desfa000]

i think a stone came into the earth and a **** big Pyroclastic cloud came over earth

THATS the way how dinosaurs a killed (-:

[SouthSaturnDelta1]

S'a lot of danger.

@ 1:49 sounded like "..to a wise killer whale"*

Holy smokes,we arent prepared for that!

*hawaii's kill something

[lowrider949]

2 the people this event will haping 2011-2020 and yes nobody cant out run this event so please be ready wen this event takes place

[SuperRedbaron221]

Knightedric forget a racecar u would need a jet to out run that thing

[SuperRedbaron221]

Forge

[knightedric]

i would need a race car at full speed to outrun this thing!

[2012wasa]

пиздато!!!

[Paint4ever2]

what program is this clip from? history channel, discovery... ?

[batmatt1001]

they think this is what happend in pompay

[stsars13]

Just to think one of these valcanos is in a freakin park (Yellowstone).....yeah, that was a smart idea... T_T

[LisaMarie216]

That's what I heard. *sweatdrop* I don't really believe it to be true though. Especially considering how fast these surges can go.

[LisaMarie216]

Ouchies. You wouldn't want to be near one of those. I heard that some have managed to outrun the Pyroclastic Flows, but that is rare They move extremely fast over the gorund.

[J7282]

at 2:09 i think i can outrun that with a car

[brwneyez101]

i know that you can outrun lava and i also knew you cant out run a pyroclastic cloud unless your undergound and i didnt know that your first breath would like kill all your intestines WOW!!!!

[Trackiller]

you cannot survive inside that thing,it has temperature about 600 c or more i think...

[Aerosmith963]

@Trackiller its 1000 degrees c now conver ttha in to ferinheit once that come out after the ash if you are within 0mi- to 100mi you are not going to make it out in time i mean like 200kmper hr thats crazy.

[SuperSuperMarioMan]

That's the last thing I want to see in my way!

[cadetgj]

I wonder if there's any way to survive the inside of a pyroclastic flow, like if you wore a mask or something. It'd be interesting to see what the inside is like, if only someone could live to tell us

[indigobluepics]

Storm chasers try to put recording instruments in the path of tornadoes to learn what it's like inside the funnel. Maybe someone could invent something to put in the likely path of a pyroclastic flow. It would have to be transmitting its data to outside the danger zone, though. The second the ash and super hot gases hit it, it would be vaporized. But that would be a neat vid to see.

[MCOvronnaz]

Yeah, but that's impossible, as this "monster" blows EVERYTHING on its path! Not even a strong structure can sustain all that pressure!

[metalhead2221]

your burned alive. a mask wouldnt help much lol

[Musicman510ee]

That was really interesting, thanks for posting!

[eternaldeadman]

mad props to whoever filmed this. I SALUTE YOU!

[CRTukker]

Look it up, pyroclastic flows do happen with almost every eruption of any volcano, most arent that big though as shown in this vid, but they do occurre normally.

[IPVentertainment]

Actually, there have been surges many times as big than those. Examples;

1. Mount Saint Helens, 1980 AD.

2. Vesuvius, 79 AD.

3. Tambora, 1815 AD.

4. Toba , 70,000 BC.

5. Yellowstone, 635,000 BC.

[MCOvronnaz]

...And Yellowstone might be okay for now, but will erupt soon. And when that happens, NOBODY will want to remain in the northern America continent... That's a supervolcano!

[Tank50us]

@MCOvronnaz Little fact about Yellowstone, it's not the only one. And her next eruption is likely to be small compared to the big ones she has at a normal cycle (once every 900,000yrs). When she goes, she'll wipe everything within a thousand miles out, and then plunge the entire northern hemisphere into nuclear winter from the ash. This will only last a few days to a week however, but the cleanup is going to take months, and cost trillions.

[MCOvronnaz]

@Tank50us I knew about that; Japan has one, as well as somewhere in the northern Russia. They are spreaded all across Earth!

About the winter provoked by ash, somebody told me that to last some 10 yrs, but I thought that a fake... Mt. St. Helens lasted for 10 yrs, but that 'cause of lava domes being successively created and destroyed. Now it stopped, and the actual Lava dome is measuring almost 100m high, I guess. Thanks for your info, man! :)

[lafanadejump]

OK....

I think I will NEVER go near a volcano!!!

What a Shit!!!

Thanx for the video, it was amazing and terrifing!! XD

[Carfer22]

was the girl running away from one in some building a fake? Surely it was.

[CRTukker]

Obviously, how else you want to record that part, no one is going to volunteer for that lol

[Carfer22]

Well the suicide hotline could be a good place to find volunteers.

I know ....in poor taste.

[MCOvronnaz]

Yeah, not even a chance! That's torture before death, as we're cooked alive! LOL XD

[crzyaznemo]

@MCOvronnaz thats not funny

[MCOvronnaz]

Take it easy, man, you're too worried about this! :D

If a volcano erupts, that's completely normal!

[SuperSuperMarioMan]

AMAZING!

[captpinchcard]

thats what it looked like when i used to change my kids diaper.
