Every other Wednesday we present a new video, so join us to see the truth laid bare...
Will scientists ever be able to predict volcanic eruptions?
Volcanoes are among nature’s most awesome forces. Over millions of years, lava and debris ejected from volcanoes have created more than 80 percent of the surface of our planet. The world’s 1500 currently active volcanoes still kill an average of 800 people per year and threaten the lives of 500 million more. By their very nature, volcanoes are unpredictable, with molten rock, known as magma, forcing upwards under almost unimaginable power through complex webs of rock fractures from up to a hundred miles under the ground.
We visit the Italian city of Naples, where 500,000 people live in the shadow of the world’s most dangerous explosive volcanoes, Mount Vesuvius. The mountain that killed thousands in AD79 in Pompeii, is now among the most solely monitored volcanoes on Earth. Scientists study its gas emissions, its earth tremors, its temperature and how the ground on and around the volcano changes shape. And yet as scientist Carmen Solana admits, “We are not right now in the position of being able to predict eruptions.”
Naked Science travels around the world, looking at how each volcano prediction method helps scientists complete the jigsaw picture of when an eruption may happen. On Hawaii, we see how often deadly volcanic gases offer clues to what is happening underground. Here, too, they measure temperature changes to try and predict if an eruption is likely.
We hear of how the study of ground deformation helped scientists predict the eruption of Mount St Helens and save hundreds of lives. And, on Mount Etna in Italy, volcanologist Harry Pinkerton reveals that the temperature of 2000 degree lava flows help him predict what destruction an eruption may cause. In New Zealand, one of the world’s leading seismologists details how her research reveals changing patterns of rock fractures in the run up to the eruption of the massive Mount Ruapehu volcano. Her studies of seismic waves, the sounds generated by earthquakes, could help prediction in other countries.
For the newest prediction techniques, Naked Science looks at stunning computer images revealing the structure of magma chambers up to 100 miles under the ground. Nobody has ever seen this deep before. To create the picture English scientists tap into the massive penetrating power of electromagnetic waves, hitting the ground in lightning storms. Finally the program moves to Iceland where scientists combat the deadly threat of under ice volcanoes by creating computer models linking the information gathered by all of the prediction methods we have seen in the film. That offers hope for the future, although the volcanologists still warn that, however much their science improves, volcanoes will still produce unpredictable and often deadly eruptions. - Věda a technologie
Jumping from couch to couch screaming hot lava doesn’t seem so bad after watching this.
I really enjoy how these series make the scientists look cool with extra camera angles, haha. I know it is a stylistic choice by producers and such, but it makes their fields look more action-oriented.
Volcano are fascinating to learn about, But very dangerous.
@richy booth What do you mean?
@richy booth Oh okay I get it.
@Northeastbornbred Very true lol I stay my distance and don't get into emotional or romantic relationships with them.
That professor who worked out how to see under volcanoes using lightning and solar flares! That's incredible. He should get some kinda prize for that. It's like the narrator said "it's the dream"
when i see a research vehicle filled with flaming volcano experts fly over my head, i take that as a possible warning sign of danger in the area.
lol ,keep living on the slope .
Heading indoors wouldn't do anything to save you from a pyroclastic flow. You're only hope is to get away from it as fast as possible.
So basically you have no hope.
It’s a good thing you’re here James
Lol IKR!!!
Id suggest not living near a volcano or atleast not in the damage path of a volcano. If it blows, those living in the vicinity of a volcano will be screwed.
you can't out run a pyroclastic flow......
I love this channel, thanks for the uploads
26:44 Volcano Detective Harry Pinkerton! Awesome :-)
You must be crazy if you don't want a volcano to spit out lava, because if it doesn't, prepare for the worst earthquake
would just like to say the cone shape volcano in New Zealand they said was Ruapehu was in fact NOT Ruapehu that was its neighbour Ngaruruhoe , the one erupting is Ruapehu
I know this because I live just underneath them :D
Heading indoors wouldn't do anything to save you from a pyroclastic flow. You're only hope is to get away from it as fast as possible.
@@stanleygood1980 I dunno....if I ever get a chance, I'm flipping over a bathtub and hoping it's like in the movies when you're stuck in a house that's burning, lol
"to save you from a pyroclastic flow" makes me think of an old outdoor survival guide:
If a black bear is attacking you, it's probably desperate for food; fight back.
If a grizzly attacks you, you probably startled it and it may have cubs nearby. Play dead and if you're lucky it'll chew on your scalp for a few minutes and leave you alone (i'm not kidding this is near enough a quote).
If you encounter a polar bear...don't. There's nothing you can do; DO NOT GET INVOLVED IN THE FIRST PLACE.
pyroclastic flows are like polar bears
Hawaii is getting some right now!!! Mother Nature !!
Heading in doors as fast as u can🤔, if your that near to a volcano that your in danger i'm not sure being inside will help much🤣
i've lost track of how many times i have seen this i want to see some new documentary on the subject
i have grown up and lived in kansas 99% of my life so experiencing a volcano in the united states is like going to a foreign country to meet their leader
You’ll to leave to do that.
Mt. Vesuvius is just a drop in the ocean compared to the much larger Campi Flegrei (Phlegrean Fields) "supervolcano" located on the opposite side of Naples
What's really terrifying is that Campi Flegrei has increased it's activity as of late, and that volcano can produce explosive eruptions similar to what Mt. Vesuvius does, only 100-200x greater
G6 Liara it has seen increased activity and has also killed a little boy and his parents after falling into a crater
I heard about the incident in the news.
The parents tried to save the boy when he fell into the quicksand, but they ended up swallowed as well
you do know that Vesuvius is part of that caldera right?
I've recently learned of Camfliflegrai sorry if i spelt it wrong. But she is very interested. I heard Vesuvius is just another vent of Camfliflegrai
*Only thing I need to survive a volcano is common sense which tells me not to get near one or live by one.*
Even that wont necessarily protect you, look up the eruption of krakatoa. It exploded so violently that it killed people hundreds of miles away by causing tsunamis and the explosion was even able to be heard nearly 2000 miles away. Some eruptions are violent enough to cause other devastating events so you dont actually have to live right next to one to be hurt by it.
Technically that depends on the size of the volcano. A big enough eruption will end all life on earth.
I love watching this now but want a newer documentary also since Kilauea erupted so recently!!
1. See volcano exploding.
2. Leave now and don't come back.
*******. Class Dismissed ****
yeah please do go try that one, in a city of around 3 million, outrunning a pyroclastic flow is impossible, no matter what films might make people think, especially when a pyroclastic flow can reach speeds of around 430 MPH, you would be both suffocated and burned to death at the same time, not a nice way to go, it beggers my belief that given our knowledge of volcano's today, that people still continue to live so close to these death dealers, its like living in a city with a nuclear bomb that is ready to go off at any moment.
@@leesmith7883 yeah, see san salvador city, it's hella close to san salvador volcano
@@satsat247 to me if i were running a country with a volcano that had a city too close for comfort, i would view it like this, the citizens are my greatest asset, i would not want them in harms way, taking into considration of the monitary cost if the volcano erupted and killed a couple of hundred people at least and the property damage costs, to me it would be more cost effective to build a new city some miles away in a more safe location and move everyone there, demolish the old city and recycle what could be recycled, sure it would take time and money, but to me the safety of my people would come first and foremost in my mind, i would not want to take the chance of loosing any of my best assets, the people who put me in office to protect them and their rights.
Really??? Don't be ridiculous... For example Iceland has over 30 active volcanics and for hundreds of years lived with them... You all are reaching like babys...
Dr Don Swan..... what a name lol
Without a doubt, volcanologists are the unsung heroes of the world.
Great value videos thankyou from rance Mitchell
Still 1 month left of 2020...
Yellowstone who?
Yellowstone: me
Great videos very informative 👏 ❤
une tres belle video de volcanos
These are already experienced scientists and they themselves accept the fact that predicting when a volcano would exactly erupt is impossible and yet the Philippine government would like to do an inquiry on Phivolcs for not knowing the Taal Eruption last Jan 12. These people should watch this.
Thank god for our "Volcano detective scientists". For instance, listen to Matt Balls' testimony. He's from from Lancaster University! 29:00
The dialogue used in this doc. is funny as hell.
We went on a cruise to the islands in the early 2000's.. St Lucia, Barbados, St Thomas, etc & saw 1st hand the power of Monserrat as it spewed black and grey smoke from the top.. the ocean water was like glass & it was rippling as though it was being fine tuned like a violin.. strangest thing we'd ever seen.. Captain came on & said it was close to erupting.. it did when we got to St Martin.. had to take another route home on the ship.. our stop to Monserrat was cancelled..
Vape nation! Wait what!? Don't mess with that volcano
Why humans will continue to die from volcanoes at 7:00.
agreed. also, u see how they all kissed it, i mean talk about herpes bruh.
lonewolf36s 🤭nasty
Cue dramatic voice and chilling music. Add jeopardy and you got yourself a show.
Fun game: every time the narrator says "eruption" replace it with the word "erection". Made me giggle like a 5th grader.
We had a good layer of ash as far away as southwest Montana after St Helen's blew up
oh..kay....i'm fearing for my life now even if where i live there's no volcano anywhere near me
yep me to
You never know.. they said that the only faults are on tectonic plates like one in California, but right smack dab in the Midwest is the New Madrid fault. Runs almost exactly where the Mississippi is...
Earthquake happened about 140 years ago. The ground subsided about 10 feet on one side and it rerouted the river permanently...
Stranger things have happened.
You're welcome. 😂😉
@@fairwitness7473 trust no one…including me…which means trust me. 😊
I do mostly like this documentary, though I find it annoying that nearly all the video from 18:00 to 20:40, while talking about the changes in Mt Hood before the eruption, is actually showing video about effects from AFTER the original eruption. Especially when they are substituting video of the rising level of the caldera long after the 1980 eruption and passing it off as the 5ft/ day deformation on the north flank of the mountain prior to the eruption.
You mean Mt St Helens not Hood,,,,and yes i agree
Around 18:00, "... under almost unimaginable pressure ...." Take heed! Let that be your warning. DO NOT USE A VOLCANO TO INFLATE YOUR TIRES!
Saint Steven ...funny.
Saint Steven protips from the CZcams comment section part one
0:52 Welp, Anak Krakatau is throwing a tantrum as we speak. Therefore, no shit.
47:30 Hubble!
a volcano near us is currently erupting...Taal Volcano in Batangas, Philippines
They show Mt St Helens summit video from the early 2000's and not the 1980's.
Why keep rebuilding a town next too an active volcano?
@gary kitson volcanic bait
Maybe it has rich volcanic soil for growing crops
Raising volcanic tremors is one of the important sign that a volcano will erupt soon!
Voice of this narration suffocates me with awfully charm!
23:37 Space satellites.. as opposed to ocean satellites.
Volcanos are awesome
Yeah true everyday the volcano erupts like the stromboli volcano
And yet, one just actually did erupt.
I am less concerned about Vesuvius than I am about campi flegrei. Vesuvius is nothing more than a small offshoot of campi flegrei supervolcano.
11:42 Earth is vaping again...
Right now somewhere in the world I’m having a beer.
Why oh why do the Italian people build so close to Mount Vesuvius ........... they have to be crazy!!!
You are such a dumbass. The area around volcanoes attracts settlements because for dozens of miles around the soil is extremely fertile and lush - optimal for farming and therefore raising cities. The tradeoff for potentially hundreds of years of civilization is the risk of being wiped out - it's the same thing with coastal cities near faultlines risking exposure to tsunamis. In that time, families can grow and move away, etc. You can't just stop civilization because of something that may not happen for THOUSANDS of more years.
@roger anderson
"volcanic ash is sterile" It's the value of minerals. It didn't take long for plants to start growing around Mt St Helens, and today the whole area is lush with trees.
Love the video but 8 adds while watching a documentary is too much in my opinion :/
The strongest eruption of the 20th century was know to be the most observed it was observed by both meteorologist and seismologist..as a volcano and a typhoon meet ... there's some evidence that it had a history unrecorded that might be even at the same scale as Krakatoa or bigger
Mount Pinatubo
Jonathan Williams Indonesia 🇮🇩.
You can search about Mt. Krakatoa
Martin Luther said; "if there is hell on Earth, Rome is on top of it".
Thank you Mr. Blaney. You speak the truth.
Anyone who knows anything about Mt. St. Helens knows that that footage used in the 1980 eruption segment is actually from the 2004-2008 dome building eruptions. Incompetent and negligent production on your part, Naked Science.
Not the part where you see the while side of the mountain slide away and then explode.
Funny, Mt Etna is erupting as I’m watching this...
There were no drones in the public when this was made. And it wasn't made in 2017 either.
I was 10 when Mt. Saint Helens blew. I remember it being on the news and was confused since as a kid I thought that were no volcanoes in the US since I didn't hear of any other eruptions ever happening. As a teen I knew there were some in the US. Btu wondered why such emphasis was put on the 1980 Mt. St Helens eruption over others since it had a low death count vs others. I didn't know back then that it was a success of predicting eruptions.
People should beware of putting convenience and real estate values ahead of science and safety.
Your front page shows a volcanologist aluminum wear .it reminds me of my baked potatos in my oven. Sorry i just had to say it he's going up close , i think a drone could help him !
What does Hubble have to do with volcanology??
Nothing! The satellite is not Hubble, but a radar satellite.
I want to tell you about a concept called "false colors":
A picture made of false colors is a way of visualize something that can't be seen or changes undetectable to the human eye.
it can be used to visualize, for example - + / - 2 meters of ground movements from 1000 's of Km's above the surface of earth.
I appreciate that Lars! I do know of false color imaging, I was pointing out the fact they show Hubble at 47:30!
@@JaseCJay probably just the people making the documentary not knowing anything about satellites and assuming they all look the same. I see similar things in videos about the pyramids, when they talk about the great pyramid they have a tendency to show the pyramid of khafre instead of the actual great pyramid.
I noticed they also showed Voyager for some reason.
Quiet ,yea right has steam rolling off it.
I love volcanoes
Somewhere in the world, right now, a volcano is erupting. I just took a massive crap, does that count...?
Hahaha comment of the vid that 😂😂😂
That’s land!
Thumbnail looks like ghost .!.
HAWAII MAN
Please upload the Naked Science episode "Supercontinent"
Praying for Taal 🙏🙏
narrator, you need to push out that voice a little more XD
PhonyPhoner Alec Baldwin
Wow
Hopefully volcanoes are treated a bit differently to, say, major storms which cause massive flooding,in that idiots who refuse to evacuate when told to do so do not get sent help when they find they are in trouble. It should be an automatic waiver for emergency services, when those who refuse to evacuate because "they been there all their life", do not receive any rescue resources.
Hawaii News? Get the f out, every1! Islands still under construction
Why is the subject of mass vs. space always get scaled to a olympic size swimming pool....why not ,oh let's say a dump truck. For one everybody has seen a dump truck and people are more familiar with the size...I have no frigging clue what a that pool measures out to, furthermore I would love to see a picture of that swimming pool hauling dirt down the road
Where's pierce bronson???
"Ground Deformation", a "key" indicator of eruption...
Seems to me there has been mention of the deformations have been recently spoken of when the discussions involve Yellowstone.
Hmmmm
People would rather believe in some religious magic trick because, to paraphrase a popular saying, "Science is hard, yo!" lol ;)
OK, pinko.
Its called denial! Which justifies actions not to move a muscle!!
and i just found out recently about mount newberry to the southeast of mount hood in the cascade mountain range in oregon here in the usa is an actual ancient volcanic crater/caldera & it's to northeast of the crater lake volcanic crater. i never knew that mount newberry existed!! MOTHER NATURE & EARTH ARE BEASTS WHEN THEY WANT TO BE!! 😲😨😲😨
Me either. Wouldn't it be great if it erupted ? :-)
The only one you might have to worry about erupting soon is South Sister
but most scientists say it will be Rainier to go off first.
David Joseph I live in close proximity to there. I love going to the cascades and checking out the volcanoes! I'll be doing geology after I finish school next year. I really want to get a Master's degree so I can play on the volcanoes. 🌋🌋🌋
The question is when... Lol
Max balls good name
The youtube channel Dutchsinse accurately predicts earthquakes.
Oh
KILEUEA.
Kilauea
Campi Flegrei is a far larger threat to Naples...and not touched on. Shame.
@ 0:49 . . . "because somewhere *in the world* ". . . I prefer to say "somewhere on Earth." The world is a different concept. It implies national boundaries and sovereign political entities with cites and government centers. The forces that create volcanoes, earthquakes, landslides and other catastrophes care nothing about politics and legal boundaries.
Dont disturb our funny poopers they are not smelling good the smell is coming from the hell . Why is he filling olympic swimmingpools with lava? Oddity.
0:28 HOLY Crap!!! I THOUGHT THAT WAS MY BABYMAMA!!
HEY DON'T JUDGE.. UGLY PEOPLE MAKE SOME PRETTY KIDS. 🤔😂😂
With all due respect for all every nation but USA failed harder during St. Hellens eruption than in Vietnam😥
Che bella professoressa!
Been watching this video multiple times. Thank you so much for the infos. I had a better understanding about volcanoes and why they erupt. At this moment, our Taal Volcano here in the Philippines is erupting and its very very powerful. #TaalVolcanoEruption2020
Aggravating cinematic technique Numero Uno: Circling an upcoming narrator about 13 times at high speed. Numero Dos: Making an upcoming narrator walk as though running at high speed. Nauseating and unnecessary. Disgusting. Why do this? Cheap tricks make their so-called scientific approach a Hollywood pretense. Why respect any video doing this? I certainly do not.
how is volcanic eruptions awesome ?
Because they inspire awe. That's literally the definition of the word. Doesn't nessiserly mean it's a good thing.
how can they not be . . .
Oh bullshit, the clips from the Montserrat eruption, are CLIPS spliced together for dramatic purposes. Watch the Montserrat video.
16:37 , 27:30
... When mother nature releases its anger!!!
why this NZ team could not predict the white island 's eruption ?
Toujours pareil même pas foutue de traduire en français .
Just don't build anywhere near a volcano........ c'mon folks, it's a no brainer!!!
You are such a dumbass. The area around volcanoes attracts settlements because for dozens of miles around the soil is extremely fertile and lush - optimal for farming and therefore raising cities. The tradeoff for potentially hundreds of years of civilization is the risk of being wiped out - it's the same thing with coastal cities near faultlines risking exposure to tsunamis.

In that case, the entire State of Washington and much of Southwestern Canada should not be there by your thinking. Mount Saint Helen's erupted in the opposite direction of what the scientists who died predicted.
@@petenielsen6683 they also thought that it would be a vertical eruption, they never imagined it would erupt horizontally.
If a "scientist" is talking to you about saving people's lives, hold onto your wallet. It's like a preacher talking to you about saving people's souls or government talking about ending poverty.
It takes a special kind of person to hear "save lives" and automatically connect it with money.
You hit your head too hard or something?
@@AleTitan - It's called "pattern recognition". A scientist who is out to get funding talks about how important his research is to the lives of zillions. Whether it's global warming, global cooling, ozone holes, you name it. The pattern is there so it doesn't take a lot of pondering to connect the dots after awhile. Everybody has an agenda and most of the time that agenda is money. Once they get enough of that, they seek power. It's the way of the world.
@@GizmoFromPizmoscientists have saved millions of lives though through their research and development. Modern medicine and vaccines have literally saved millions of people from things like small pox and polio. But unfortunately there’s a lot of people that are anti science for religious and political reasons so we’re falling behind the rest of the world because 40% of Americans still think Jesus rode dinosaurs and hate science lol.
So billionaires pay people like Tucker and other conservatives to spread vaccine hesitancy and anti science rhetoric because culture wars prevent people from fighting class wars and asking for a living wage. So now after their years of investment despite the wonders of science there’s people in CZcams comments that think scientists have some unified conspiratorial agenda and are somehow getting rich lol. All it’s missing is any logical motive or evidence.
maybe they should try other method that predicts all natural disasters, animal behaviour, likelly in some of us a sense of impending disaster is ignored by drinking or taking another pill, relearning to interpret signs from the sub conscientious may save you from more than a bad marriage
Dear Naked Science,
Why have you used misleading footage when describing the cryptodome that formed on Mount St Helens? Almost every clip you used while discussing the events leading up to the 1980 eruption showed videos of the lava dome that formed AFTER the eruption ... it's almost as bad as fake news ... please consider using honest footage in the construction of your future documentaries.
Kind regards,
A concerned CZcamsr.
If its getting hotter up here,its bound to be getting hotter down there too.!!
The only way the temperature of the atmosphere would increase the temperature of the core would be for the atmosphere to get hotter than the core. Heat always seeks equilibrium so it will always move from a hotter area to a cooler area.
THEY NED TO CHECK ON YELLOWSTONE
THIS VOLCANO CAN ERUP ANY OF THIS DAYS
Edgar Benitez I mean, when it erupts, North America is screwed any way. Might as well enjoy life, in my opinion.
Really will NM be effected
That's a great idea! Somebody needs to show the head of the USGS this comment. Good thing you were here to warn us all.
