USGS Scientist Gives Hawaii Eruption Presentation (May 22, 2018)

[@awhite7596]

This is one of the best videos and explanations I've seen of the eruption. The information is very clear, the pictures of where the lava is coming from are fabulous! I can't stop watching! Keep the info coming. Thank you for sharing, and my heart goes out to all those families and people whose lives have been permanently affected.

[@noahyohannes6270]

This lies they setting hawai for doom:(

[@amberstarr23]

I live in minnesota and I cant get enough either!! Its just incredible!!!

[@Dt0x75]

Noah... STFU please! They are certainly not lying, and any small piece of education in geology, even grade school would show you that... If they are lying then take ur ass to the volcano, take measurements, publish a paper and allow us to examine and replicate your findings... But until you do that, please keep your fucking mouth shut!

[@jamesgrist1101]

it was poor that they couldn't estimate how long the lava flows would last. If they know its the high reservoir being drained from a new lower exit then after over 30 years of study they should have an estimate of the size of the reservoir, coupled with estimates of the flow rates and pressure would give an estimate of the duration. College maths. But that's why geologists become geologists and not STEM scholars, useless at anything analytic or technical.

[@brendanh8978]

It sounds almost as if the new eruptive center might be moving down rift for the long haul. That's bad news for the people that live in the Puna area. It didn't go on for too long in 1955, but who can really say why it stopped then, and if it will do the same again.

[@robertnorthrup1914]

One of the best explanations thus far. I fully empathize with him (the speaker) on trying to give a technical talk to non technical folks so they understand better as to what's going on. I am a retired engineer who had to do these types of presentations and it wasn't easy to limit or eliminate the "uh and um" especially when thinking on your feet. With a canned speech this should not happen so cut him some slack. His explanation of the "conduits and balancing of lava levels" is good. He seems very knowledgeable as to how volcanos function with ducts, vents and flows.

[@ktpinnacle]

Exactly.

[@RoxnDox]

He is knowledgeable about it, he’s one of the scientists who have been studying the volcano for many years...

[@phtechnical]

He is a good speaker, knowledgeable and makes it understandable. I hope he speaks more.

[@jahcubeblbeczek6328]

phtechnical he is not telling the truth! He explained how, but didn't say why... PGV for sure!

[@amberstarr23]

Awesome footage too!!

[@candicehoneycutt4318]

Jahcube blbeCZek What specifically do you need explained?

[@brendanh8978]

His explanation was what I have peiced together over the last two weeks, but it was good to see it confirmed and it put into one presentation. A lot of doom mongering and misinformation out there.

[@Wandanador]

You get my recognition for a most excellent presentation. I notice a few others appreciate your efforts, too.

[@JR-yq9qi]

Probably the best and most honest and thorough explanation yet.

[@joyleenpoortier7496]

That was the best information session of the whole eruption process. Finally it has been explained to the people what is actually going on and probably will continue for a very long time. I think that this is the new system that is going to stay around perhaps for the next 35 years.

[@JohnnyMotel99]

Slowly the locals will adapt and move on. They know they live over a volcano, it's already in their DNA. As the USGS guy pretty much said, this could go on for a long time until the reservoirs reach equilibrium.

[@elmurcis1]

As seen on live webcam, lava flow changes time by time but in general, its steady and kind of "predictable". As long as it keeps steady pace, even some lost usable ground won't be big issue. Only kind of new cracks somewhere else (and new fissures erapting) and/or some serious eruption from central lava-channel could make things worse. After initial evacuation and after lava got to the ocean (nobody could be sure how serious that moment can be), it kinds of makes me less worry about future, just anybody near it has to keep eyes wide open and be ready to move some miles away more. Enjoying this action and same time crossing fingers that locals won't get too much trouble. All best from far far away Latvia =))

[@bobholland9924]

Do y'all realize we just witnessed somthing very rare . A scientist admit they just don't know. Bravo this man did the best report I've seen come from the USGS.

[@chrissy7033]

thank you for explaining.

[@thfield2417]

What a great teacher. Sharing this with every teacher I know. Thank you, USGS.

[@Andrew-ep4kw]

So how often does a geologist give a presentation to the public and get applause? Nice to see.

[@kimberlydkulcsar2671]

It seems as though the lava is only going towards the ocean. I have been following all of you on this subject. I truly am sorry for all of your loss. I thank the Lord you are all alive and doing well considering. My prayers are continually with all of you and Hawaii.

[@larryscott3982]

Kimberly D Kulcsar This eruption is as normal as rain. And it’s a slow motion event. Not a Mt St. Helens.

[@douglasbrannon6525]

Kimberly D Kulcsar someone positive.

[@tarnocdoino3857]

This would inform me that the new longterm location of volcanic activity has moved to the area currently erupting. Having lost a home to a fire, my heart goes out to those displaced. But it’s also a good time to consider permenant relocation.

[@Syclone0044]

WOW!! 6:40 is when it really gets spectacular! That's the best footage of fast flowing lava rivers I've ever seen!

[@MrPeterhemm]

Best and most interesting presentation I have heard so far!

[@ianstradian]

Great graphics and explanation.

[@18i]

Very nice presentation!

[@maryuniverse79]

Thank you USGS Scientists for the explanation and all the job you are doing. 🌋

[@denabrown8912]

Best video and explanation on this eruption so far, thank you

[@knightriderlayingdownarubb9715]

Greatest fireworks show on Earth no gunpowder needed Thank you mother nature

[@harrykuheim6107]

All they need to do ,or can do, is back off and stay out of the way... and watch ...

[@Dt0x75]

lol Rocket very true... All you need is magma and SO2 as a proper propellant

[@camilleroseministries]

ROCKET MAN Space Odyssey Oh its not mother nature- its [pseudo] father Satan...

[@Syclone0044]

It's a great show, but this is a child's sparkler compared to the cataclysmic 1883 eruption of Krakatoa! That created the loudest sound in recorded history: 330dB. So loud it echoed around the Earth 7 times in a row!

[@Dt0x75]

True, but I like natural firework displays that leave me with my hearing intact! lol

[@Dabadabadoobie]

That was a nicely done presentation

[@CheapTart]

Really excellent explanation! Science teachers across the globe should show this to kids along w Scott Wiggers videos. Incredible to learn.

[@Nobody-11B]

Absolutely beautiful.. Deadly but stunning.

[@carbo19]

He didn't explain the blue dot.

[@drlyndacramer]

As a conspiracy theorist, I always say "do not think about what was said, think about what NOT was said". You are absolutely right there mate.

[@julie.nieleherrick7647]

The blue dot is a location that has a different chemistry from the others. He was describing the significance of the colors where green means older chemistry (decades-old lava) and red means mixed chemistry (a mix of old and newer lava).

[@XeroBeing]

As a former resident I feel for the locals, however we, as americans, we deserve everything that is coming to fruition.

[@stephenwest673]

Went here in 1993 and got a helicopter over the Pu o’o vent that was just a lava lake, then took a car round to the Crater Rim Road and watched as lava oozed out the ground, spellbinding stuff, Kileaua crater was just a vast black landscape with little activity. How I wish I could be there now to see this 👍

[@marksommers6764]

Great , concise description.... Thanks .

[@alexanderthegreat5553]

He sounds like a a first grader trying to explain his project,can’t believe that guy works there.

[@bowser123ism]

Best explanation by far. Good job

[@nicholaosmiller2793]

EXCELLENT, presentation, this gentleman, USED, real easy to understand wording, NOT a bunch of TECHNICAL terms, Well Done!!

[@emilyw5522]

Looks like the migration/birth of a new volcano. Fissure 22

[@cassiosilva1340]

Excellent explanations, technical answers but easy to understand for the laity. One question: If not appear volcanic fissures spewing lava, the eruption the main crater would be greater proportion?

[@rod1148]

I wonder what the temperature of the lava is as it leaves the fissure.

[@artcurious807]

Very interesting. So we could possibly see this lava activity go beyond the previous eruptions that lasted close to 90 days. That would add a lot of land to the big island. Btw, have they started digging trenches around the geo thermal plant yet? How about putting up concrete blocks? Now might be a good time.

[@sirmoke9646]

A trench will get filled up it will spill over concrete blocks but most importantly (and seen quite clearly from the footage) the lava is flowing away from the plant.

[@veronicasuestarlite4080]

Thank you for your detailed, concise explanation.

[@rps4646]

Very nice explanation

[@denawalters176]

About time we got some good explanations..

[@joyfunderburk5272]

Such amazing information! Thank You

[@BrknVeel]

who's bright idea was it to make the interpreter for the deaf impossible to see? thanks for leaving us just as ignorant as we were before you paid that interpreter for her hard work. i see people thanking him for clearing this up so much...it would have been nice to be one of them.

[@lizzetcastro73]

Now we talking about . Best explaining since it started it

[@leavemyhandlealone321]

Excellent detail good explanation there, ignore the critiquing trolls. They have nothing better to do obviously. And at a critical time like this they spend their time critiquing... Sad people

[@phildouglas9086]

Linda Perez Stop being so critical. Thanks.

[@Letty-q3h]

Phil Douglas I agree 👍

[@ktpinnacle]

Being critical of being critical of critical trolls. OK . . .

[@ktpinnacle]

5nikki50 Check. Like our friend JAE.

[@veronicasuestarlite4080]

Jae Mary Greeley has never DRILLED DOWN TO FIND THE MAGMA CHAMBER EITHER SILLY PERSON. Everything BPE says is "maybe" "perhaps" "if this" "not certain" "for example". You want to make a bet on anything BPE says over USGS says with me? What is BPE's crystal ball prediction about Kilauea? I'm seriously interested. Where can I read their writings?

[@jefft4303]

Back in 19 whatever, old magma cooled a bit, constricting or even plugging up the conduit, but only at a point east of Pu-u-O-o. You know this because lava lake levels at Pu-u-O-o, and the summit crater rose and fell with pressure changes from the main hotspot. You also know the old magma conduit probably didn't "freeze solid", or else it wouldn't be spewing today. It remained under pressure, and recently, something gave way, to re-open that part of the conduit. The weak new flow melted more rock and broke off other obstructions, widening the pipe. You can probably go back to the seismic records and watch this process, with the benefit of hindsight. Good chance the weight/pressure of the vertical column of magma and lava lake at Pu-u-O-o caused the recent major change. Had it been the main hotspot inflow, or the summit crater, you'd have seen the lava lake at Pu-u-O-o fluctuate first, but it didn't. Now, there's a new "balance of pressure". This balance includes reduced "head heigth" at the two old lava lakes, and outflow from the fissure system, and inflow from the main hotspot. Pressure is the key variable, but there are supporting variables as well. Magma that's sitting still, but buckling ground above it, can begin outgassing, reducing pressure, leading to accelerating outgassing and more fracturing, a potential vicious circle. Moving magma, under pressure, pushes outward on the conduit walls, and, at certain points, exhibits complex pressures. Moving magma is at lower pressures than parked magma, until it encounters a bend in the conduit or obstruction, at which point, the moving mass and velocity squared can come into play. 300 to 600 foot high fountains imply generous velocities, which, if squared, can dwarf other forces, temporarily. Lava, in air, tends to cool. All of the visible lava today...is tomorrow's possible plug that ends this eruption cycle. One partially melted rock, lodging on an obstruction, a few degrees cooling, this could end suddenly. But historically, there have been several. surges or cycles, before long term, static (non-eruptive) equilibrium is reached. Once the initial flow pinches off, another weak part of the system lets go, and moves more magma till it pinches off too. I feel for the geologists. Everyone wants to know what happens next...and even the volcano doesn't know that. Best bet. When things do start to slow down, watch the seismic events closely, with a system wide map in mind. Where the quakes happen MAY let you know how the whole system is reacting to increased pressure as tbe current fissure flows cool off and become plugged.

[@ladykiri42]

Mahalo!

[@douglasbrannon6525]

This has good information and detail.

[@GODSpet]

Thank You and Please stay safe.

[@Classsslady]

Mahalo, good explinations, I am curious to know if the glass (Pele's tears) is being made into jewelry?

[@marshallbs]

I wonder if a new crater will form where rift 22 is erupting. It seems like a new conduit is forming under that lava fountain. That power plant will definitely have to be relocated as periodic lava flows could continue for years in the vicinity, much like the zone around Puu Oo.

[@GetReady4LiftOff]

Yes what if this goes on indefinitely for years?

[@colettelane3728]

Great report done by the geologist, it help's explain a lot.👍👍

[@lauralee6432]

I can't imagine being there. It must be hard for all those people who live there, what happens to all the animals, love stock. Etc.

[@arabella959]

Laura Lee the livestock is being secured and large and small animals have places that were designated to shelter them. Matson lines paid for a container of large animal feed to be shipped last week. This County has been on it since the start. This is not the first eruption here and they are doing remarkable work throughout the agencies. Volunteers taking care of animals if families cannot.

[@peterbroekhuisen4618]

Saai

[@mustardseed308]

Amazing explanations, Thank You.

[@virginianemith]

Thank you, excellent presentation, i can understand this and I am not a geologist etc.

[@DerpMcDerp101]

So does Hawaii have 132 more lots added to its land?

[@victoriademesa]

Very interesting! The connections between Pu'u O'o and Halemaumau

[@arjaramo8362]

Leave everything and RUN !

[@jerrybobteasdale]

Doesn't it look like that part of the island is apt to break off? It looks like there's a line of very fluid magma delineating that chunk of land. I wonder if section slides down abruptly?

[@thisisagoldengranny]

Could this be natures way of carving off a land shelf that will separate from the main portion of island?

[@johnarizona3820]

Is that conduit to the lower rift zone to scale or even close? If so that would be or could be a permanent fixture and when large events happen naturally it could seemingly act like a shotgun propelling mass ejection down line perhaps creating an entirely new summit closer to the ocean.

[@TheRolemodel1337]

are there tourist discounts now or are the prices going up? i want to see this with my own eyes :D

[@landieh6162]

It's beautiful and yet sad...

[@colettelane3728]

Prayers for everyone's safety.❤

[@gma8328]

How many acres have been covered?

[@tylerpassannante3868]

G Ma - 1700 acres, last I heard.

[@MrBonners]

That whole slab along the line is going to float off.

[@OleOlson]

Great explanation, though the cutout was a bit unclear in terms of location and depth. This eruption is really exciting!

[@magin9228]

As it gets closer to the thermal plant, do u think you will see bigger fissures and more activity?

[@laurabarber6697]

I feel for the people that are responsible and have such a huge sense of responsibility of reporting, filming, answering to the General Public about a situation that no one has any prior experience with. Okay yes was been volcanoes before it but this is an act of Mother Nature and therefore it is a unique experience. Please be sure to get plenty of sleep, take your vitamins and don't drink very much coffee. take good care of yourselves mentally physically and spiritually because is the man said this is going to take awhile so you need to be able to be strong for the Long Haul!

[@richardenglish4563]

What would the difference in chemical composition between the green and the red? Would the green spots be more mafic?

[@MrMRDUGIE]

What would be nice to know now is, What does the USGS rate the risk of the land mase sliding into the ocean.

[@drfix2020]

I take it with all that is happening now in the lower elevation Mauna loa is much less likely to erupt now, or am I wrong? Any geologist out there?

[@hedgeandhue]

Really great explanation.

[@themerrigans2734]

Good coverage.

[@keno1961]

Thanks for a clear explanation..

[@sofachips]

Wow so crazy, be safe everybody.

[@pa5287]

very interesting and simply said too

[@indiana146]

You can’t stop nature

[@Duricas]

I've never heard pond (ponding) used as a verb before.

[@johnnyg3681]

NOW THIS MAN MAKES "SOME" SENSE. THERE ARE A LOT OF QUESTIONS STILL. SOME OF THE EXPLANATIONS ARE CONJECTURE AND THEORY.

[@JaseCJay]

Thought I had a bunch of stuck pixels..whew!

[@jamesdewey3259]

Lots of info in that talk. Hope this stays as low key as it is. A slow eruption is better then a energetic one. To the people of HI the very best of luck.

[@scallie6462]

How would they create an energetic volcanic eruption? Other than dropping a fucking bomb in the cauldera, no human intervention is going to influence this eruption. People thinking they have any ability to do so are dumb as the rocks being formed.

[@mamboferido4741]

Is this the longest period the volcano is erupting?

[@rixt3r862]

Is the graphic that shows the cutaway of the volcano available somewhere on the usgs site?

[@Hoffmanpack]

Sustained down pressure was a cork , the flow is increasing beacuse the cork is releasing expect the flow to increase until climax?

[@malanaganz7188]

I wish the ASL interpreter had been included in the filming.

[@tv_pc2311]

szkoda że nie ma jakiegoś tłumaczenia napisów.

[@michaelharris4651]

Is this going to blow its top ?

[@SteveHyde1959]

Magma is at the earths core, lava doesnt come from the earths core it is created where the tectonic plates grind against each other , didnt anyone else learn this or have I flipped parallels?

[@marleneengleman88]

Sold information!

[@dawnfaialaga5840]

This was so helpful great explanation 😁

[@dustydustydusty]

Volcano empties and collapses. Goes boom.

[@AvgDude]

What happens if and when that entire block of land from the fissures to the shore sloughs off into the ocean? Good times.

[@angeec.3312]

In 1914, the Mount Pele volcano in Martinique erupted; 30,000 people lost their lives... This is a different type of volcano; however, very unpredictable, as these fissures seem to open up "everywhere." These 1.43 million people should have been evacuated, starting weeks ago. They would now have to be confined to the areas farthest away, but who knows where another vent could open up...

[@MegaTriumph1]

I like the part where he says notice the perfect riff of fissures right below the PDV plant. Most likely the plant caused this and a large part of the mountain has a high possibility of sliding off into the ocean in the future.

[@george-yz5fo]

Incredible stuff what goes on deep within this planet. Always been amazed at how much it can actually affect the way we live and react, sadly lives are lost but hopefully those in the know will be able to find out more about how these things tick if I may use the term and save lives and also wildlife.

[@daveyjones9930]

Where's the fire trucks and Fire Fighting Tankers and earth moving equipment (to dig channels) to protect the Hydro Plant? All we hear are status reports and some complaining (which are good or normal)...and we see NO proactive ACTIONS to halt or mitigate the lava flow, especially that which threatens PGV.

[@coastalfog809]

Are the eruptions that are happening in Hawaii, caused by the underground nuclear explosions from North Korea????

[@ianb9028]

No they are not.

[@laurabarber6697]

my concern is when the lava chamber empties because it's found its new balance at a lower elevation that it will collapse. And by collapsing that can create another whole collection of scenarios of negative possibility :-(

[@steammausss164]

I got this video In my suggestion video anyone else?

[@whatfreedom7]

I just hope that whole side doesn’t slide into the ocean creating a tsunami and massive explosion.

[@davidcook7926]

hell is enlarging itself .for all those people who reject they Bible .

[@Khumry]

hes forgetting say YET

[@benth162]

So you Linda, Phil and Letty believe that the USGS is all knowing and no one else can do any better job of conjecturing what is on the line? Has the USGS said anything about the depth of the Riff Zone which is important when it comes to the possibility of that whole section sliding off the shelf into the ocean. It makes a big difference. That riff zone looks like a knife cutting through a cake, but yet the USGS continues to not report of that possibility. Also, we must ask why is that riff zone bubbling up now and why in such a straight line. Lets hear some actual discussion on the possibility of those "Whys". It is better to get it out now, than have anyone in the vicinity if and when it goes creating a huge Tsunami.
