Struck by volcanic lightning...
You are the physical manifestation of bad luck.
Irvine Spiegel then a mirror falls on you and cracks... A ladder falls near you and you stumble through it from the volcanic lightning and mirror... A building falls on you and then you accidently hold an umbrella for balance... Then a crack appears and you step on it....
Ben Hoffman if someone survives all of that wouldnt it make them the luckiest person alivr
There's a photo on Pinterest looking down a road towards the Mt St Helens eruption filling the sky, but stopped in the middle of the road with a motorcycle hitched onto the rear is a Ford Pinto!
Even if the owner wasn't struck by lightning, they certainly deserve to have been!
Kevinito9 no because if he was lucky it wouldn't have happened.
Kevinito9 he would have become the unluckiest creature in existence
"Scientists and photographers are persistent," and in some cases ever so slightly singed.
The title should be "Volcanic Lightning: Because Exploding Mountains Aren't COOL Enough"
Volcanic lightning = Pikachu. Because it's caused by... *Ash*
Goddamn you to hell.
*upvotes*
Makes sense that It's cause by "trainer" Ash after all we know as little why "trainer" Ash does the things he does as we do about volcanic lightning
Yes. Then again: No it's ofcourse a MAD pikachu because Ash took away the yummy red ketchup...
ok i loled xD
But his name is Satoshi not Ash.
All that rubbing...sudden burst...explosive eruption
( ͡° ͜ʖ ͡°)
I have to be very wary of Volcanic Lightning when I bench press exploding mountains.
Muscle Hank you mean movement of tectonic plates
MUSCULAR HANKULAR WANKS OFF ERRECT VOLCANO AT 3 P.M (OMYGOD U WILLN'T BELEIVE WHAT HAPPENS! TERRORFING! 😨😨😨😱😨👌👌👌👌👌😤😤😨😱😨😨😨😱😨😨😨😱✡️✡️💉💉😱😨😨😱😱💯💯💯🔥😱👉👉👌👌:O)
Muscle Hank
Video or it didn't happen.
Muscle Hank
Congrats!
You want to find out Alan?
( ͡° ͜ʖ ͡°) ( ͡° ͜ʖ ͡°)
Liking this video just for the title
I agree with the water mixed with the volcanic lighting. Also you don’t take about pressure change at all with the massive amount of mass moving
People hit by volcanic lightning , are as unlucky as hell , boy ! That's damn unlucky
I apologize to anyone reading this who will never watch Stefan the same again.
Stefan is the master of hand gestures while talking. His hand movements perfectly line up with his speaking cadence and inflection, to the point where I can imagine his hand movements even when he isn't visible on screen
0:30 I love that photo. The mix of colours and the way it seems to glow as if with an aura, just makes the photo eerily beautiful.
It's a nice idea to a fire/electric type pokemon.
Volcanic Lightning? Is that a new Marvel film?
Good job, Stefan.
My god this is great information. Scishow is my hero... especially Stefan chin.
DUDE! That t-shirt is awesome!!!!! I want one! Where can I found like yours? You know, to be as stylish as you!
Funky Sagan Cat Me to me to
I want one too!
Why is there a thumbs down already lol. There's no way you watched this already, it was released 10 seconds ago
The dude.
J-sizzler probably just some haters doing their regular job
J-sizzler maybe they subscribed just so they can immediatly downvote things? I mean humans can be really petty horrible people....
"Because exploding mountains aren't bad enough" is one of the best quotes I have ever read.
Loving the title.
Constructive Criticism: Stefan does a really good job of getting the information across. His voice and tone and speed of delivery is very clear. The only thing I see he should work on is his gesturing. Move those hands in other directions instead of looking like your rubbing a pillar or something. Doing the same gesture over and over becomes distracting after awhile. Try moving your hands horizontal at times instead of just vertical. Like, when describing the ash cloud, move your hands outwards to describe size.
Great piece. Where can I get that great T-shirt?
Loving that slogan. Really sells it lol
Hey! all this volcano talk is pretty timely for me, since I am summiting Mt. St Helens tomorrow :P
So the lightning in Mordor atop the Orodruin(Mount Doom) isn't just because of Sauron's hate against people who are prettier than him.
Can you have a take on lighting balls? Balls of lighting that slowly come down and explode
You should check the videos of Taal Volcano eruption which happens days ago. The eruption included magnificent lightning display.
I love the title
Well explosive eruptions can happen if the magma drops below the water table and vaporizes a large volume of water at once...like they're worried about on The Big Island....and an example of another is Mt. St. Helens, which had volcanic lightning and was potentially caused by a steam explosion.
Nice
I've seen volcanic lightning once. It was a tiny eruption but (insert a big chunk of bad words) it was scary!
Is that volcano compilation video done yet?
If Natural Disasters were a game, Volcanic Lightning would be the BOSS BATTLE!!!
I remember hearing about lightning violently striking a man's car as he was driving away from Mt St Helens, & surviving with just a little singeing, but the freaky thing was that it wasn't the first occasion he & his car had been struck by lightning!
Taal 2020 Eruption: Hey!
i was hoping you’d show a sample video ?
Thunder & Lightning, Very Very Frightening~
I would love to know where I can get the LEM shirt. Is it available to purchase anywhere?
I imagine all the friction coupled with the fact that water makes a good conductor when not in a pure form is probably correct. I don't know how conductive ash is - it probably depends on the minerals in it - but rocks aren't generally known to conduct electricity all that well. However, dust, ash, etc. can be quite good at generating static charges.
I wonder if water and lava under pressure mixing together is what causes some of the big explosions during an eruption.
Love volcano lightning
Dam. Zeus, Hephaestus are you guys fighting? Again?
Electromagnetic energy is released from the earth during earthquakes, volcanoes and any other activity where it can escape from inside of the planet, where it should be. This happens from fault lines and other weaknesses all the time, and is dissipated in the ground for the most part. Obviously it is particularly strong somewhere like this.
If you read about the British Airways flight piloted by a Captain Moody (was his first name Eric, I forget) he was flying a 747 over Java, and they had St Elmo's Fire on the windscreen and all 4 engines stopped working. This was in the 1980's and the ATC didn't think to warn them that they were flying over a volcano. Interesting and relevant story. The engines actually began working again when they got lower down. Gave everyone a very nasty fright and the sandblasted the windows.
When you misunderstand regular lightning, there's not a chance you will understand volcanic lightning. They're not creating charge separation, they are restoring charge balance.
Bill DeWitt 1:10 “...a huge charge imbalance which eventually gets evened out by a sudden burst of moving charge in the form of a lightning bolt.”
That’s exactly what he said. Lightning is CAUSED BY charge imbalance.
Sorry, I was talking about the larger systemic separations, but I see that I was not clear about that. By "they" I meant storm systems and volcanoes as a whole. They exist because of larger planetary and interplanetary charge separations.
Oh hey, I translated part of that same letter by Pliny the Younger in Latin last semester. Apparently Pliny the Elder died after sailing to Vesuvius to try and rescue people. Gave me more respect for the guy, since I used to just think of him as "the wildly inaccurate bestiary guy"
Cool
Why don't the particles disperse before the bolt? Like charges repel each other, is the force to weak at the distances of the water molecules or the ash molecules?
I am here because of Taal Volcano lightning from the Philippines.
Volcano...Lightning.... Someone get me a Tiger and an Electric Guitar and let's do this.
Taal in PH is now doing this. OMG!
Aren't there also relatively large charge imbalances between existing surface rock and flowing, spattering lava (with its iron able to change direction in the flows, etc)?
Yeah, pretty sure it's mostly the dust... This also happens in deserts during sandstorms, and the humidity there is very low to non-existent compared to volcanically active regions.
Should be mentioned one of the rare deaths by volcanic lightning was also the only casualty of Parícutin, the new volcano that was born in Mexico.
Woah
Make a video about Kilauea
That IS a huge ash cloud...
3:07 ASH? He's muckin around with Pikachu!
Lightning... get it? ._.
Mother nature is so cool...
Isint there also Cases of ball lighting forming from eruptions?
Like this
I would like to find the person who is editing these videos and subject them to unpleasant sights and sounds for the time it takes for me to get to sleep at night
Recently Taal Volcano has had lightning occurring in its eruption.
How is there a thumbs down already lol. There's no way you watched this already, it was released 10 seconds ago
BillyClutch how is there two posts identical from different people on this? Someone just cutting and pasting?
Peter Who who?
BillyClutch seems you an owl? :)
Pliny t younger: "town destroyed, uncle killed, exploding mountain, fire everywhere and now lightning...
What's a good idea? Sail a ship right into it and write some postcards!"
Piezoelectric effect from silica in magma quickly going from high pressure to low pressure....the crystals are under strain which builds a charge..the eruption to our low pressure environment causes the micro crystals to fracture and dump their charge..
David Harris neat!
Guys - regular lightning is probably driven from above (Google sprites, blue jets and other more significant electical activity occuring immediately before lightning strikes) especially given the now confirmed plasma interactions in our atmosphere.
...I wonder what is driving the lightning from volcanoes! Who knows? Maybe there is some kind of charge separation within the earth that causes this. Maybe the earth is charged differently in the core. Potential gradient of 120 volts per metre from sea level (above the earth's surface). I'd love to know what that electric field is within the earth!
Maybe we can use news like this to shed us of the pre-Copernican Earth (or Copernican Sun) as the centre of the Universe view from an electrical perspective? We are part an electic circuit from the sun, which is probably part of a galactic electric cicuit, etc.. I love Eugene Bagashov's "There is no ground in space"
I thought it had something to do with volcanic ash and friction causing a static charge to build up in the plume of smoke?
It rubs it out.
Charged molecules from the volcanoe rub together causing a spark. The spark sets off the chain reaction of a lightning bolt as the energy is distrubuted through the medium.
When two charged molecules love each other very much...
Hey SciShow! Can you make a video about volcanic mesocyclones and what it takes for one to happen? I read about them in Le Prince des Nuages” by Christophe Galfard; they’re fascinating!
*DAT ASH*
What's the chemical composition of the ash? The heat could be breaking the ionic bonds in the atmosphere helping creat a pathway for the lightning to form (these are two different questions btw. Well a question and a statement. Idk if there are any volcanologists in the comments)
I miss u hanks
See, I TOLD you Rescue Heroes wouldn't lie to me!
Pliny the elder did his best to describe what he saw but I don't believe he was the first to describe this phenomenon.
The name of the video made me laugh so bad
Does planting by the moon cycles really work? i'm sceptical...
Lightning is caused by crystals banging into each other. Rainstorm lightning is caused by ice crystals banging into each other. Volcanic lightning is caused by volcanic ash crystals banging into each other and as we all know (do we all know?); when you squeeze a crystal it changes shape and releases an electric charge.......
Lightning strikes
You what would be cool? If they actually showed volcanic lightning happening while explaining
Volcanic lightning = value added.
We do fully understand how it works. The issue is, describing how it works could lead to the end of Energy scarcity. So the Science is suppressed.
What if it's the lightning that causes the volcano? And not the other way around? And the same goes for the weather?
What causes the color of the volcanic lightning to be so different? Is the color of the lightning itself different, or is the color filtered out because of the gases and Ash that the light has to pass through before reaching our eyes?
Hello Taal spectators!
dude, that video title though.
Can't I just do the prince zuko move and redirect the lightning and harness its power? That'd be nice
Probably ash, like a forest fire/brush fires, causing lightning and starting a new fire.
Where is Hank and Michael ????
Think of normal lightening its a mixture of particles rubbing together and a mixture of hot and cold all are which are present in and around the volcano.
I can't decide which one is cooler. Volcanic lightning or tornainbows.
if you see a thunderstort hitting an erupting volcano then it's probably time to run.....and I don't mean towards it..
Why don’t you make a video on the alternative theories about the Universe on TH-cam this would be interesting and good for the TH-cam community!!!
THERE'S A PLENEY THE YOUNGER?!
I’m watching this with my neck stuck
Wouldn't all that liquid hot magma and ash shooting into the sky cause the natural moisture in the air to boil and become steam at the top of the death cloud?
Fiery ash full of small bits of metal and such rubbing against each other causing lightning?
think about the dust lightning on mars
Isn't it theorized that lightning caused the first complex organic molecules to form or something along those lines? Maybe it was volcanic lightning o.O
Volcanic lightning...because there's no limit to how bad things can get.
It's the midichlorians releasing force lightning
