As someone whose studied a lot of physics, here’s my explanation for the larger explosions. For the most part the lava has been flowing quickly but gently into the ocean. As heat conducts out of the lava into the water, the surface cools and hardens forming a crust. Lave continues to flow downhill underwater. As long as the lava flows in a laminar manner, the crust expands smoothly and only a small surface area of liquid lava is directly in contact with the water (wherever the crust is cracking and spreading). However, if the flow encounters an underwater cliff (possibly the terminus of an older hardened lava flow), it might drop very suddenly. The sudden drop might cause so much tensile stress on the crust surrounding the flow (due to the flow being stretched under its own weight) that it fragments. This sudden fragmentation leads to a turbulent mixing of liquid lava and water. Suddenly there is a very large surface area of liquid lava in direct contact with the water. A large volume of water then vaporizes, exploding to the surface mixed with fragments of liquid lava.
I think it's possible that the bigger explosions initiate through a chain reaction. The first small explosion begins as the crust shatters when the flow spills over the edge of the hardened underwater terminus. Even a small initial explosion can blast away the protective crust on nearby lava and cause additional liquid lava to turbulently mix up into the water above. Once this happens you can get progressively bigger explosions that involve more and more exposed liquid lava as the crust is blasted away over a large section of the underwater flow.
I think the USGS should have been more clear in warning tour boats about the potential for underwater explosions even hundreds of meters beyond the shoreline entry point. The lava continues to flow downhill underwater and a boat going anywhere over top the underwater flow is in danger. I imagine underwater steam explosions could potentially reach the surface even a kilometer or more from the shore. The underwater flow is only protected by a thin crust. Anything that disturbs the laminar flow and creates turbulent mixing of exposed liquid lava... like the breaking up of an unstable underwater levee/dam near the terminus, sudden underwater cliff spillover, etc... can possibly trigger a large underwater steam explosion. Being anywhere over an underwater lava flow in a boat is like being over a massive underwater pile of dynamite. Even just dropping a heavy object like an anchor into the lava could set it off.
My best understanding-guess is lava can form underwater tubes that can travel some distance to then form pillow lava some distance out to sea (notice the boiling steaming waters many meters away from shore). In the event that a tube pressurizes and shatters can suddenly expose large volumes of lava to water all at once. It can even chain-react by introducing water into the tube that is then carried with the flow eventually blowing up the tube like a pipe bomb.
This looks similar to what I experienced working in a steel mill. It was common knowledge to everyone in the melt shop that if water was floating on top of the molten steel it would just boil and turn to steam harmlessly. But if the water became encapsulated with in the molten steel or the molten slag on top of the steel it would flash to steam violently. When water flashes to steam it expands something on the order of 14000 times its volume. This happens instantly and creates a violent explosion.
Samuel__ Absolutely correct. The nearly instantaneous transformation of water into steam gas releases unimaginable amounts of energy, only surpassed by designed explosives like gunpowder or c4.
Small example of what will happen when seawater comes in contact with a magma chamber exposed by a major earthquake below sea level. It has happened around the earth many times in the past.
They explain it at 11:00 It even goes onto the very next question from another caller. Hmmm... they, "...didn't see it." (The lightning) But they do explain how it happens, but I don't believe they really do IMO. Plus they warn only one question from each caller. Anyways so a caller phones in and asks her question and the continues on to ask for a second question. Take a listen 13:09 Why snap at someone and then let them have the second question anyways C'MON #STICKTOYOURGUNS
The helicopter overflight video is always good. If it is safe, can you please get some video from the area of the Kapoho crater where the main flow direction changed last week? Also, does someone have an estimate of the depth of the main lava channel? Thanks.
USGS, Please explain why you lost equipment at one of your monitoring sites in the past few days to a lava overflow. Last week, you reassured local residents that the USGS had crews monitoring the lava flows 24 hours a day seven days a week. If you were unable to save your equipment from a lava flow, should local residents and the mayor of the big Island of Hawaii trust you to be able to warn people who are in the path of another lava overflow in time to save their lives?
The question about whether the Hot Spot boat was at a safe distance or not... it got hit by a lot of debris, causing quite a bit of damage. The obvious answer is, in or out of the 300 meter range, it was not at a "safe" distance
Rosemann07__ There was lightning in the cloud, and quite a bit of it actually, "But we are Blind! We have no Mind!" U.S.G.S. said factually. Creative writing is such fun, when you are not the only one And wisdom grew where fungus sat, a tribute to the Cat in the Hat!
That thing is like a huge bomb, no wonder that boat got hit. That must of surprised the crew, cause it wasn't exploding like that. Good thing that boat has a metal roof, even though it went through it.
The lightning was visible in the spectator videos but its likely that the lady from the USGS hadn’t seen the same videos. A likely explanation of the lightning in the littoral explosion steam plumes can be heard at 11.48.
Saw the lightning, bound to happen. Lava tubes or hot lava bubbles can develop under the water. When enough pressure builds inside them they burst, evaporating the surrounding water. The effect is similar to putting a frozen turkey in hot oil, boom. Now watch as soon as they see my post they will use my explanation,
Actually, the lava flow into the ocean reminds of Genesis when land came out of the sea. In typology the sea represents death and the land life. Thus, land coming from the sea can be thought as life emerging from a situation of death. The same for a seed buried in the ground emerging out of it as life or fruit producing plant. Resurrection is like that, what comes out of the ground is better than what was buried.
Just put something hard on the top of your boat. Also if we get some good fragments from the explosion can we bring them back to the USGS for analysis? Let's come together and get some mass spec analysis. :)
You clearly don't have very good powers of observation, do you? See that hole in the roof ot the lava boat? That's 6mm aluminium plate, backed by 100x50mm box tube.
She did say they think the explosion is related to the typography. Speculative hypothesis based on the observation of a scientific event is not purely speculative. A heated un-vented pressure cooker does what? So, Topography + Lava Flow + Trapped Water Volume = Volumetric Compensation or Boom! I didn't notice the lighting on my first inattentive View on my second viewing I did notice several electrostatic discharges, so is it possible she didn't witness lightning?
It was an unfortunate accident ... who among us has not learned something from unfortunate accidents? Praying for the girl that got her femur broken .. can't even imagine the terror she is feeling. May peace be with them all.
i have a few questions. i have watched a lot of videos in the last few days but no one has ask or said anything. so i will if anyone can answer. it seems to be more less moving through the same path now pretty steady. but whats the chance of it changing paths and say start going north? and how many extra miles of new land has Hawaii gained? and last how long will it be after this nightmare stops will it be before the land will be any good for anything
My questions are: At what date did the 61G flow cease flowing? I seem to recall in March 2018 they still had (commercial) walking and bike tours going out there even after there was an on-land gas explosion that killed the tour guide (biz owner) and was partly inhaled by one of the tourists. Would inhaling this at close range cause permanent lung damage? What about yesterdays on-water explosion? The boat reversed out of there "enveloped" in a steam cloud according to eye witnesses. Will these people receive follow up checks to receive lung exams? I know the best particle masks will not keep out the gas itself...
You can see the same effect in larger eruptions. Ash particles generate a huge static charge that discharges as lightning. Google "volcanic lightning."
Check out the engine housings @ 10:15. That whole boat was pelted HARD with fragments and chunks of molten hot lava. @ 9:49 see on the left where the huge stone punched through the roof. Greed outweighs common sense sometimes.
I think it is ridiculous that people get that close to this ocean entry. they need to keep people away from it, and people that go out on those boats put their life in danger by getting that close to it
There are currently about 37 volcanoes erupting on the planet right now, volcanoes have been discovered as the the source of 3 past global extinction events ......go figure
AMC__ That looked like a new eruption, going on near the ocean entry Is it possible there's a new rift, in this spectacle of the century? Or was the lava playing games and what could be it's motives? To scare a boat of tourists by playing with explosives!
Hopefully the tour company has enough of the correct insurance to cover this event but because the tour boat was in violation of the law by going too close, the insurance provider might not pay the claims for injuries and such. If the tour company is not incorporated, the owners are going to be looking for more than a new source of income......they could lose everything because of what happened yesterday........sad
Agreed, acting irresponsibly with total disregard for the safety of the passengers on board that boat........if the state does not close them down, then lack of business will. The authorities took the boats GPS so they will know exactly where that boat was when the lava bomb hit, someone could be facing criminal charges?????
Mayor of the big Island of Hawaii: please ask the USGS to explain why they lost the equipment at one of their monitoring sites in the past few days to a lava overflow. I believe you were at this meeting in which they told local residents that they had people monitoring the lava flows 24 hours a day seven days a week. Given that the USGS was unable to save their own equipment from a lava overflow, should you trust the lives of your citizens to them?
William Warren Thank you, we noticed that. Always wanted a gov job, never got one even with science degree, but I could have answered many questions here!
Good thing the USGS has no responsibility for the safety of residents in it's charter then. Their responsibility is to record, tabulate and share data and theories with other agencies and the public.
Different risk tolerance for unmanned equipment vs human lives. They deliberately put that equipment in risky places for exactly this reason... it’s expendable. Humans aren’t. They gather data knowing that the equipment might get lost. It’s an acceptable cost to gather data that may help keep humans safe in future volcanic events. I’m not the government’s biggest fan, but saying they can’t be trusted with lives because they lost some equipment is utterly nonsensical.
Also that stone that's forming is besalt which is conductive. It could be forming a salt water capacitor and arcing all that current when inside the steam bubbles.
Stone W The commentator answered questions based on still photos available to her. She can only report on the information she has at hand. A gentleman from the weather service did tag onto her answer and confirmed that lightening did happen. You may want to listen again. I think this is the problem of taking questions on an ongoing event. It is hard for everyone to receive the necessary information. 😀 I’m glad I don’t have to do their job.
The soltero ocho Durrstruction They were comparing the differences in the ocean lava entry from 2016-17 with the current event and how the differences influence explosions when lava meets water. Isn’t this fascinating stuff? 😀
WireTamer 😄 I had never seen the 2008 footage before, so I was glad to get a look at it. I was working a job that took 70 hours a week to do. Now I’m retired and getting caught up on everything!
Is there a 3D map over time in relationship to all events on earth, with Hawaii as some sort of echo chamber of planetary seismography? It would be attempted to be integrated with all other "noises" and digitally turned into visual maps? Is that a model, including gps?
I find it ironic that despite Kilauea volcano being the most heavily studied volcano in the world and yet the USGS does not know what is going on or what is next? What are they studying? With all of the ground equipment and satellite data they have access to, how can they say that they don't know ??????
Tammy__ Keep in mind that the Hawaii Volcano Observatory was only established in 1912. That would mean that they have only 106 years of concrete scientific data and over half of that was done with now obsolete equipment. Considering that Kilauea is estimated to be 400,000 years old, do you really think that USGS can make an exact prediction of what will happen next? If you had done any research on your own you would understand how unpredictable the volcano has proven to be in the past and making predictions without data to back it up would be irresponsible. Many of the events in this eruption are first time encounters so it's best to just watch and learn. I will agree that these USGS spokespeople seem more concerned with what is occurring at the summit and that they have not been keeping a close eye on the total picture. Maybe they need 2 teams, one up at the summit and another on the ground and they need to get together and issue more timely, collaborated updates. They shouldn't be waiting for the public to start clamoring for information. At least they should show that they are trying to stay ahead of the game.
I think it's wrong and the media reporting that Ikaika's company is being named as one of the ones involved in yesterday's accident, and THEY WERE NOT. Their business may suffer from this. The media who reported this incorrectly needs to immediately RETRACT their story and present FACTS on the true name of the unfortunate lava boat tour company involved. It is sad all the way around, and it baffles me why the Coadt Guard would REDUCE the safe distance when HVO has clearly made clear their position that 300 meters should be considered safe.
Truly, I am amazed how this volcano still erupting, I think this volcano is building a continent as big as America & one day this will be gone & remain in history book
that was kind of a weird non-explanation - why are there explosions? well, the lava hits the ocean and the resulting steam expands ad that's an explosion. kinda like, the explosion is an explosion... well, yes! but why? lava is always going in there and the lava is always hot, and the water is always wet and the steam always happens....why is it sometimes just steamy, and sometimes explode-y?
It's difficult to know exactly how it happens because it is a very difficult and dangerous place to take measurements. Here is my explanation: The lava flow underwater is usually covered by a solidified crust, as the lava flows underneath it may deform and break this crust, periodically coming directly into contact with water causing explosions. What probably happened to cause the larger explosion was that the crust covering the lava flow broke up over a larger area exposing the lava very rapidly to the water, this caused rapid steam formation and explosion.
Its a stupid answer because it was a stupid question. Here is an example of an intelligent question: Is the lava flowing from the minor ocean entries, different in any way from the lava flowing from the main ocean entry? How long is the delay between summit crater collapse event, and an increasing in flow from fissure 8? Has this delay changed in duration throughout the eruption? How long does it take for a spillover lava flow to completely solidify? At what temperature does the lava become rock? At what temperature does the crust of solid rock become an insulating layer?
It is steamy if the contact is continuous. It is explode-y when there is a sudden contact of a lot of hot material with water. Can be a large blob of lava covering and including a pocket of water. Can be an overcrusted lava tube cracking open and water rushing in. It may also be water simmering, displacing the water column above, thus pressure reducing, and suddenly a lot of overheated water flashing into steam. I'd expect more of steam, less of a debris carrying explosion in the latter case.
More people are starting to realize that volcanology is based on speculation and theory more than anything else, most of the time they just don't know why these events happen just like they don't know what triggered this new eruptive phase of Kilauea.
B molitor__ Whether there is an explosion or not depends on the volume of lava piling into the ocean at that point and how rapidly the seawater is converted into steam. The more rapidly a liquid converts to steam the greater the release of energy and that release of energy has to be unimpeded. The easiest way to illustrate this is like this: If you have a pot of oil on the stove hot enough to deep fry frozen french fries, and you tossed in the frozen fries one at a time there's no danger, but if you dumped the whole bag all at once you will have an explosion and end up in the hospital with serious burns. That's because the amount of energy being released is confined by the size of the pot, resulting in an explosive event.
They need to give fissure eight a nice name. It’s pretty clear that the fissure has taken over. The parent volcano has closed up shop now. The base and walls of the original volcano are just plunging deeper as the fissure eight has taken over all of the eruption activities now. Start a contest and rename fissure eight, it is doing all of the normal volcanic duties. 😉 😎
So it's an ancient train that was uprooted by the lava flow that still had water in it's tank from an infinity ago. So basically an unknown race had developed steam locomotives possibly before life on earth this time. Unbelievable. 😐 Calling it a submarine is because it wasn't identified as an ancient steam train and misidentified as a submarine..🤷 9:27 you see the goal car explosion revealing that coal decays over infinity resulting in a less than spectacular explosion.
She, as a researcher, should familiarize herself with the most recent activities. If she doesn't like the "lava boat" term maybe she should coin a better word.
I hope you guys watch your own videos, so that you will see that there was lots of lightning throughout the clouds of the explosion ans throughout the event period. You sounded a bit dismissive at the idea of the lightning.

What a fantastic explanation, thank you USGS....

Did anyone see the lightning produced by this explosion? 5:29
Lightning is common in volcanic ash events. As though it’s not spectacular enough as it is.....
Can't the lightning also be a part of the spectacular feature?
Yup saw the lightning! Lots of friction caused by the particulates.
They explain it at 11:00 It even goes onto the very next question from another caller.
Hmmm... they, "...didn't see it." (The lightning) But they do explain how it happens, but I don't believe they really do IMO.
Plus they warn only one question from each caller. Anyways so a caller phones in and asks her question and the continues on to ask for a second question. Take a listen 13:09
Why snap at someone and then let them have the second question anyways C'MON #STICKTOYOURGUNS
Don't get me wrong. They are doing a great job Plus I do understand they are seeing pictures and not video :)
The helicopter overflight video is always good. If it is safe, can you please get some video from the area of the Kapoho crater where the main flow direction changed last week?
Also, does someone have an estimate of the depth of the main lava channel? Thanks.
Great, clear report. Lots of new images and information. No robot voice. At last a decent content as to what is happening
Thanks for the videos and live cams too. You guys rock. Keep the usgs feeds coming.

"But we are Blind! We have no Mind!" U.S.G.S. said factually.
Creative writing is such fun, when you are not the only one
And wisdom grew where fungus sat, a tribute to the Cat in the Hat!
So her answer to how much lava, was 50-100 cubic meters per second. That yields an average of 6.5 million cubic meters a day.
Lightening has always been active with erupting volcanoes caused by interacting with the sun
Any good adventure is risky.
Enjoy adventures while you can.
That thing is like a huge bomb, no wonder that boat got hit. That must of surprised the crew, cause it wasn't exploding like that. Good thing that boat has a metal roof, even though it went through it.
new island forming here. could take years!
Not yet, Hawai’i is still getting bigger.

Something seems not right to me, those explosions would seem more indicative of a submarine fissure opening up.
She did say they think the explosion is related to the typography.
Speculative hypothesis based on the observation of a scientific event is not purely speculative.
A heated un-vented pressure cooker does what?
So, Topography + Lava Flow + Trapped Water Volume = Volumetric Compensation or Boom!
I didn't notice the lighting on my first inattentive View on my second viewing I did notice several electrostatic discharges, so is it possible she didn't witness lightning?
The lightning was CLEARLY visible in the explosion...
She clearly stated she viewed images. Not video. Had she viewed this video, she would have seen it and stated as much.
Fuddy Duddy there are cones from volcano there 500ft drop it looks like an eruption from cone
Fuddy Duddy this is an eruption they lying
What are you talking about?
I guess Janet's not on fb...I saw loads of clips featuring the lightning
It was an unfortunate accident ... who among us has not learned something from unfortunate accidents? Praying for the girl that got her femur broken .. can't even imagine the terror she is feeling. May peace be with them all.
5:30 you can see lightning in the explosion column.
How could she not see the lightning in the ash plume? It is her job to observe?
Andre n. She saw still photos not the videos.
And yet shes giving the explanation, without having even reviewed the evidence.
I’m wondering what’s going to really take place when the rains come into the area.
that didn't look like the 'usual' explosive ocean entry. i muse that its a fissure erupting under the ocean. time will tell.
Damage Control--You would be wrong. You have no concept of the mechanics of a volcano.
"Bread box"? That size comparison gave me a laugh. Everything else is so technical and then you hear "bread box".
There is always lighting .Yellowstone is awaking . I hope it will be a small eruption and not a planet killer
michael lennon scary
Dear geologists: eliminate confusion by calling them lava floats.
Stunning video. loved it of the ocean meeting the lava.
Amazing Incredible speechless
A lot of good info, The static lightning discharges where very evident
Where are these people at to see this without being arrested?
There is lightning at 5.29 !!!
i have a few questions. i have watched a lot of videos in the last few days but no one has ask or said anything. so i will if anyone can answer. it seems to be more less moving through the same path now pretty steady. but whats the chance of it changing paths and say start going north? and how many extra miles of new land has Hawaii gained? and last how long will it be after this nightmare stops will it be before the land will be any good for anything
Big Island is a bigger island🧐
What were they showing 2008 footage?
To reiterate what a lava explosion looks like.
There is NO information that is restricted. For get the federal dynamics of "need to know" this has evolved to a critical dynamics
My questions are: At what date did the 61G flow cease flowing? I seem to recall in March 2018 they still had (commercial) walking and bike tours going out there even after there was an on-land gas explosion that killed the tour guide (biz owner) and was partly inhaled by one of the tourists.

Will these people receive follow up checks to receive lung exams?
I know the best particle masks will not keep out the gas itself...
It's beautiful! especially the tiny island.
What is the " lightning effect " I keep seeing in these explosions ?? Thank you, Peace
Friction caused by ash circulating.
lohphat Thank you my Friend for your response, Peace
11:04 it was explained
You can see the same effect in larger eruptions. Ash particles generate a huge static charge that discharges as lightning. Google "volcanic lightning."
Colonel Angus Thank you my Friend, yes I've seen that too
Thanks to the USGS for all their hard work.
It was a trick question, the depth of the new island and connecting land is.. Above land. :)
Check out the engine housings @ 10:15. That whole boat was pelted HARD with fragments and chunks of molten hot lava. @ 9:49 see on the left where the huge stone punched through the roof. Greed outweighs common sense sometimes.
I think it is ridiculous that people get that close to this ocean entry. they need to keep people away from it, and people that go out on those boats put their life in danger by getting that close to it
Common sense is not so common anymore.......
Isn't it likely that these eruptions and the ensuing carbon gas emissions into the sky is likely to contribute immensely to global warming?
There are currently about 37 volcanoes erupting on the planet right now, volcanoes have been discovered as the the source of 3 past global extinction events ......go figure
Francis Ssemaganda Yes which is why we shouldn't cut down all the forests, which turn the CO2 pumped out by volcanoes back into O2.
No, lord Trump confirmed global warming is false. He's the true and one and I belib him.
That looked like a new eruption going on near the ocean entry. Is it possible there's a new rift?
AMC--No.
AMC__ That looked like a new eruption, going on near the ocean entry
Is it possible there's a new rift, in this spectacle of the century?
Or was the lava playing games and what could be it's motives?
To scare a boat of tourists by playing with explosives!
No, it’s probably just a lava tube that collapsed. There is another volcano, but it’s 3000 feet underwater and way off the coast.
John Doe Make sense! Thank you.
Mother Nature is spectacular and awesome!
I think its a new vent. There is dust in explosion, that is what caused the lightning surely? since when has steam caused lightning?
Why are you using 'file' video from Aug 2008!?! Isn't there enough current action to show?
I just want to know why are humans so defiant towards nature😒
It was just a matter of time for the boat people.... They get way too close!!!!
Why aren't they asking someone who is actually up to date with whats going on.All she says to everything is idk or I haven't seen. lol
I've always wondered if the Hilo tsunami evacuation signs were a "safe distance"...
She did not observe the lightning? They are like 7 flashes of light in the cloud. Hello...
The boat left the safety zone. Major lawsuits ahead.
Yea that tour company is done........bye bye business.......hope it was worth it
Tammy.. The injured can practically write their own checks.
Hopefully the tour company has enough of the correct insurance to cover this event but because the tour boat was in violation of the law by going too close, the insurance provider might not pay the claims for injuries and such. If the tour company is not incorporated, the owners are going to be looking for more than a new source of income......they could lose everything because of what happened yesterday........sad
Tammy well they should lose everything they endangered all those ppl.
Agreed, acting irresponsibly with total disregard for the safety of the passengers on board that boat........if the state does not close them down, then lack of business will. The authorities took the boats GPS so they will know exactly where that boat was when the lava bomb hit, someone could be facing criminal charges?????
heads up....do you have an evacuation plan for the whole island?!!!!!!!
Why do they need one? Because you can't comprehend, or are too lazy to find out, that it's a small event on a very large island?
Mayor of the big Island of Hawaii: please ask the USGS to explain why they lost the equipment at one of their monitoring sites in the past few days to a lava overflow. I believe you were at this meeting in which they told local residents that they had people monitoring the lava flows 24 hours a day seven days a week. Given that the USGS was unable to save their own equipment from a lava overflow, should you trust the lives of your citizens to them?
William Warren Thank you, we noticed that. Always wanted a gov job, never got one even with science degree, but I could have answered many questions here!
Good thing the USGS has no responsibility for the safety of residents in it's charter then. Their responsibility is to record, tabulate and share data and theories with other agencies and the public.
It was a calculated decision. Its not worth risking lives for some equipment.
Different risk tolerance for unmanned equipment vs human lives. They deliberately put that equipment in risky places for exactly this reason... it’s expendable. Humans aren’t. They gather data knowing that the equipment might get lost. It’s an acceptable cost to gather data that may help keep humans safe in future volcanic events.
I’m not the government’s biggest fan, but saying they can’t be trusted with lives because they lost some equipment is utterly nonsensical.
finally, a fellow reasonable person.
great images
Thank you for good report,stay safe
You know, one thing that could be making the explosion bigger is molten metals that are trapped in the lava that are reacting with the salt water
Also that stone that's forming is besalt which is conductive. It could be forming a salt water capacitor and arcing all that current when inside the steam bubbles.
The USGS lady said she didn't see any lightning with this explosion. She needs to look closer. There DEFINITELY was lightning in this explosion!
Stone W The commentator answered questions based on still photos available to her. She can only report on the information she has at hand. A gentleman from the weather service did tag onto her answer and confirmed that lightening did happen. You may want to listen again. I think this is the problem of taking questions on an ongoing event. It is hard for everyone to receive the necessary information. 😀 I’m glad I don’t have to do their job.
Very common for volcanic clouds... full of particles rubbing against each other.... full of static electricity.... ZAP!
They lie.
I saw lightning as well. Since that lady is from usgs she should know lightning occurs every now an then at volcanoes.
She didn't want to see lightning with this explosion because then she would have to try and explain that too.
11:20-11:27 then you're blind. You can clearly see it several times, and the people even react to it on the raw video.
Janet Airlines Were you listening? She had only seen still photos.
Someone kindly inform Janet there's shitloads of footage of the said lightning all over social media
Why show 2008 film?
The soltero ocho Durrstruction They were comparing the differences in the ocean lava entry from 2016-17 with the current event and how the differences influence explosions when lava meets water. Isn’t this fascinating stuff? 😀
They think we are idiots with no memory.
WireTamer 😄 I had never seen the 2008 footage before, so I was glad to get a look at it. I was working a job that took 70 hours a week to do. Now I’m retired and getting caught up on everything!
Maybe to show the difference between this lava entering the ocean, and how it did in 2008?
Hahahehehahahehe
The Big Island is getting bigger, I wish someone could explain the explosion better
YES I SAW THE LIGHTENING
Is there a 3D map over time in relationship to all events on earth, with Hawaii as some sort of echo chamber of planetary seismography? It would be attempted to be integrated with all other "noises" and digitally turned into visual maps? Is that a model, including gps?
4:28 this is some old ass footage or something! WHO THE HELL STILL USES A FLIP PHONE TO RECORD? Especially in HAWAII!
John Smith if you keep watching, the video shows a date of Aug 2008.
Is this a lava coming from a reservoir or direct of the center of the earth
I find it ironic that despite Kilauea volcano being the most heavily studied volcano in the world and yet the USGS does not know what is going on or what is next? What are they studying? With all of the ground equipment and satellite data they have access to, how can they say that they don't know ??????
Tammy__ Keep in mind that the Hawaii Volcano Observatory was only established in 1912. That would mean that they have only 106 years of concrete scientific data and over half of that was done with now obsolete equipment. Considering that Kilauea is estimated to be 400,000 years old, do you really think that USGS can make an exact prediction of what will happen next? If you had done any research on your own you would understand how unpredictable the volcano has proven to be in the past and making predictions without data to back it up would be irresponsible. Many of the events in this eruption are first time encounters so it's best to just watch and learn. I will agree that these USGS spokespeople seem more concerned with what is occurring at the summit and that they have not been keeping a close eye on the total picture. Maybe they need 2 teams, one up at the summit and another on the ground and they need to get together and issue more timely, collaborated updates. They shouldn't be waiting for the public to start clamoring for information. At least they should show that they are trying to stay ahead of the game.
your understanding of science is elementary.
well, oh great one please enlighten me
I think it's wrong and the media reporting that Ikaika's company is being named as one of the ones involved in yesterday's accident, and THEY WERE NOT. Their business may suffer from this. The media who reported this incorrectly needs to immediately RETRACT their story and present FACTS on the true name of the unfortunate lava boat tour company involved. It is sad all the way around, and it baffles me why the Coadt Guard would REDUCE the safe distance when HVO has clearly made clear their position that 300 meters should be considered safe.
WOW, seriously wow. Great visual coverage. Is this recent activity anything like what we know from the 1924 eruption?
lightning comes when cold air mixes with hot air, basic science every one should know from going to standart school
wrong
I love watching the lava blobs flying.
There was a face in that explosion cloud.
Spurious Effect
Always is.
These scientists are exceptional.
Why did she choke up on the lighting question?
Truly, I am amazed how this volcano still erupting, I think this volcano is building a continent as big as America & one day this will be gone & remain in history book
All that extra weight from that new volcanic rock on that slump can't be good.
Its going to go at some point.
the magma dome is moving laterally
I think the Tourist from Asia, Mainland and EU need to be within inches of this lava flow. Why? Go figure LOL.
Who still has a flip phone? There was alot of people in the video with flip phones .
Lavaboats unfortunate name, but funny! As are the 'lava fish'
0:33 For a littoral explosion that is *huge.*
that was kind of a weird non-explanation - why are there explosions? well, the lava hits the ocean and the resulting steam expands ad that's an explosion. kinda like, the explosion is an explosion... well, yes! but why? lava is always going in there and the lava is always hot, and the water is always wet and the steam always happens....why is it sometimes just steamy, and sometimes explode-y?
It's difficult to know exactly how it happens because it is a very difficult and dangerous place to take measurements. Here is my explanation: The lava flow underwater is usually covered by a solidified crust, as the lava flows underneath it may deform and break this crust, periodically coming directly into contact with water causing explosions. What probably happened to cause the larger explosion was that the crust covering the lava flow broke up over a larger area exposing the lava very rapidly to the water, this caused rapid steam formation and explosion.
Its a stupid answer because it was a stupid question.
Here is an example of an intelligent question:
Is the lava flowing from the minor ocean entries, different in any way from the lava flowing from the main ocean entry?
How long is the delay between summit crater collapse event, and an increasing in flow from fissure 8? Has this delay changed in duration throughout the eruption?
How long does it take for a spillover lava flow to completely solidify? At what temperature does the lava become rock? At what temperature does the crust of solid rock become an insulating layer?
It is steamy if the contact is continuous. It is explode-y when there is a sudden contact of a lot of hot material with water. Can be a large blob of lava covering and including a pocket of water. Can be an overcrusted lava tube cracking open and water rushing in. It may also be water simmering, displacing the water column above, thus pressure reducing, and suddenly a lot of overheated water flashing into steam. I'd expect more of steam, less of a debris carrying explosion in the latter case.
More people are starting to realize that volcanology is based on speculation and theory more than anything else, most of the time they just don't know why these events happen just like they don't know what triggered this new eruptive phase of Kilauea.
B molitor__ Whether there is an explosion or not depends on the volume of lava piling into the ocean at that point and how rapidly the seawater is converted into steam. The more rapidly a liquid converts to steam the greater the release of energy and that release of energy has to be unimpeded. The easiest way to illustrate this is like this: If you have a pot of oil on the stove hot enough to deep fry frozen french fries, and you tossed in the frozen fries one at a time there's no danger, but if you dumped the whole bag all at once you will have an explosion and end up in the hospital with serious burns. That's because the amount of energy being released is confined by the size of the pot, resulting in an explosive event.
When i saw the flip phone i literally laughed my ass off liike who the fuck owes those 🤣🤣🤣
They need to give fissure eight a nice name. It’s pretty clear that the fissure has taken over. The parent volcano has closed up shop now. The base and walls of the original volcano are just plunging deeper as the fissure eight has taken over all of the eruption activities now. Start a contest and rename fissure eight, it is doing all of the normal volcanic duties. 😉 😎
I like how the mini island looks like a twisted demon head.
The only thing amazing here is that someone is still using a flip phone in 2018
So it's an ancient train that was uprooted by the lava flow that still had water in it's tank from an infinity ago.
So basically an unknown race had developed steam locomotives possibly before life on earth this time.
Unbelievable. 😐
Calling it a submarine is because it wasn't identified as an ancient steam train and misidentified as a submarine..🤷
9:27 you see the goal car explosion revealing that coal decays over infinity resulting in a less than spectacular explosion.
The face at 12:08. Reminds me of the face. On the Quaker oats container. Or a captian on a British navel ship.
She, as a researcher, should familiarize herself with the most recent activities. If she doesn't like the "lava boat" term maybe she should coin a better word.
4:28 People still use those old Samsungs. 😯
I hope you guys watch your own videos, so that you will see that there was lots of lightning throughout the clouds of the explosion ans throughout the event period. You sounded a bit dismissive at the idea of the lightning.
By looking at the video the lightning was clearly visible!
Henk Vermeulen the video shows later a date of Aug 2008
Lots of good info, mahalo!
