- Hawaii's Kilauea volcano could soon send boulders and ash shooting out of its summit crater in the kind of explosive eruption last displayed nearly a century ago. CBC science commentator Bob McDonald explains why Kilauea has been continually erupting for centuries and how it compares to other volcanoes.

He literally just explained for 3 minutes that this volcano isn’t going to blow up and shoot boulders into the sky, and after explaining she asked him the same question lmao
This man has a teaching gift.
it's common knowledge on the island by LONG time residents.
Listen to CBC Radio every week at noon -- he spends an hour talking to scientists about the science news of the week.
Great teacher says the mountains have more water then an island surrounded by water?
katz person Amen.
katz person I remember Bob from Canadian TV as a kid. You are right.
Finally, someone using common sense to explain this and not overexaggerating what is happening and blowing it all out of proportion as most on the mainland have been doing.
yes, except volcanos are...UNPREDICTABLE.
For the most part yes, however, this particular volcano is a lot more predictable than most others because it is a different type of volcano than all others around the world. Hawaii's volcanoes are among a very few in the world which are not influenced by the collisions of tectonic plates. Our volcanoes sit directly in the center of the tectonic plate, not around the edge like most other volcanoes on the planet. Another thing that makes this particular volcano more predictable is that it is not sitting there building up pressure waiting to pop like a pimple. It has been continuously releasing pressure with continual eruptions every day for the past 35 years.
Unlike what Bob said about Visuvius, Krakatoa, Mt. St. Helens, and most of the other volcanoes in the Ring of Fire, you can't get out the way of those when they go. They just go. That there has been the continued centralized activity means all you have to do is get out of her way and you'll be fine. Unlike what happened to Pompeii and Herculaneum and to a degree what happened to Thera.
Yea, Strato Volcanoes are quite a bit different than Shield Volcanoes. Ours is lazy and does everything on "Hawaiian Time" lol.
WH6FQE - The Kilted Piper a lot more predictable? Your on a volcanic island. What if your predictions are wrong an the whole thing blows up? Please forgive me because I think you all living on a volcano need heads examined
I wish the host would stop interrupting him
OMGshinyobject
She's doing him a favor, he needs to breathe.
OMGshinyobject I can’t stand it when people do that! It makes you think that they don’t care about what you’re saying! 🤬
Why does the Hawaii Kilauea volcano keep erupting?
BECAUSE IT IS A VOLCANO!!
Also The Grand Solar Minimum is upon us .....
because it is a hot plume volcano feed from deep through the mantle of the earth
Holy moly, who would have thought!
#staywoke
And they fired Up CERN...
Case closed.
Lmao this news reporter keeps trying to make it sound dramatic.
DefineFox but don’t you rocks can be shot into the sky?!
If this was your neighborhood, it would be pretty damn dramatic.
Not really he's just explaining what's happening.
DefineFox she also Interrupted the guy 3 times
DefineFox This volcanoe is bad. In different places the earth cracks into an next thing you know you have lava in your backyard.
I think the thing is this volcanoe is alot different than anyone is used to seeing. So to people it looks real bad. Because of how different this one is.
I was wandering why it looks different. People think of a mountian that explodes an lava pours down.
This is in a very huge area coming up from cracks in people's yard. So this is why people are like what is going on..
The ground cracks in people's yard. Next thing you know lava is coming up. Some people look at the door an a lava river is flowing. This is really different an people are freaking out.
I was wandering the same like what is happening. Then when he says its different I understand. However I was like I never seen anything like this before.
Lady: Boulders they scare me
Bob: well then stay away from them.😃
This man just taught me more than any of my teachers all together
That is one happy volcanologist!
I NEVER UNDERSTOOD WHY PEOPLE REBUILD CITIES AGAIN & AGAIN IN A DANGEROUS PLACE, I GUESS PEOPLE NEVER LEARN THE FIRST TIME.
АНУШAРВАН ХƟСРƟВ Why do people build houses again when a tornado destroys it?
A dangerous combination of arrogance and stupidity that has plagued our species since it began.
Because it's the far cheaper than anywhere else on the island. It's either there, or move to the mainland away from friends, family, and the only life some people may know.
Have you ever seen a concrete trailer house?
It’s because land on an active volcano is very cheap, and that is what most people can afford only
History channel is somehow going to explain that aliens are responsible.
Very true lol
😂😂🤣 or time travellers
lol "But...Aliens"
Malik naaaaaaá, is Trump's fault.😱
Did they got mandatory volcano insurance?
Explained that pretty well... I have a much better understanding of how it works now, Thx Bob...✌ 😉
I wonder about this as well, why an active volcano keeps erupting?
SuperBat yep these are the questions that keep me up at night. And other things like has anyone ever seen a fire ant turd lol
Could the word ACTIVE give us the answer???
Kevin P you don't need to comment ACTIVE when he himself is making fun of it
Where is ja?? So he can make sense of all this
josselyn 😂😂
Good analysis Bob. It's amazing how much bad info gets out there to the media. I've been exploring Kilauea for 27 years. Its very visitor friendly 99% of the time. The current Leilani eruption is so infrequent its been 58 years since something like this has occurred. Here on the Big Island, we run to eruptions, not away from them. I wish they'd kept the park open and issued everyone metal garbage cans lids to protect themselves from the pea-sized rocks when it blows. No different than being in a hail storm :-) I've used them before to protect my gear where lava blobs were spattering.
lavapix
Except 8 ton boulders are falling into the caldera and when it gets plugged it will blow those boulders out over a mile.
While anything is possible, there's no evidence of previous explosions sending ton sized boulders beyond the caldera itself. Most of the rocks get pulverized. I explored that entire area numerous times when it used to be open. Of course, I understand them being better safe than sorry. This is the largest one I've ever found still within the caldera's inner edge. lavapix.com/#/gallery/volcano-400-499/498sq-115140105/ Its smaller than a bowling ball.
lavapix
It happened in 1928. They've talked about it many times.
lavapix explains 1000 earth Quake's didnt have that back then only when GYOTHERMAL dugged in to the ground
It's not about the explosion it's about that earthquake that will cause an mega tsunami, that's what I'm afraid of thnx to GYOTHERMAL
Bob: But we have to wait for another thousand years for that.
Lady: So how much longer can islanders expect for this to last?
🤦♂️
WOW very informative, thanks
the news lady is trying to make it bad but the dude ia completely turning negative into possitive
Why does the Hawaii Kilauea volcano keep erupting? It's a volcano, that's what volcano do they erupt.
That doesnt answer the question.
A lot of volcanoes will not t erupt in our lifetime and for 1000’s of years after. Some millions.
Fred Norman and some are dormant.
I want to see meteor shower all over the world one day and we call it the ends of human races
That is sooo deep Fred!
I felt like I was in history class all over again when he started to explain the meaning of the volcano
Nice report, nice video, nice interview. Thanks for explaining everything so well and clearly and thanks for the approach, that I share completely.
One possible answer of many is; The main vent, may have broke into a large mouth cave system that goes for possibly a few miles, with other arteries connected. Displacing ground water into steam as it travels. The steam pressure at times multiplying at times, as it makes it way back to the original mouth and back out main vent having no quicker access elsewhere, causing greater eruptions at times?
He's a good teacher.
You explained that very well, thank you.
I love to see a scientist so enthusiastic about the earth the way I feel❤
Because a volcano gonna do what a volcano does
lol right
Why don't we just get a giant cork to plug up the volcano
Yeah nobody has died yet, let's make it deadly /sarcasm
The cork would eventually melt or be shot out under pressure
wow bob is so good at explaining things, i wish he taught me science in school!!
This Man is a great teacher and has alot of passion
thank GOD it is slow, I hope the animals are able to escape as well.
Diademglo Animals are smart. They know how to escape disasters.
The high tailed long before the volcano erupted.
Oh no the turtles😱
Thanks the laws of physics
OKQ OSRS turtles are surprisingly faster than you think
Historic, tragic, and beautiful. Pele' at work. Stay safe Hawaii!! Pahoa ohana.
CrymInAction Pele at work? you will perish because of your idolatry. The cities of Sodom and Gomorrah were not spared why should you? you do the same things they did. Repentance leads to salvation
I was reading the comments and I guess everyone was thinking the same. This man should or I hope he is a teacher. Wow, his way of explaining and giving a visual to help us understand is amazing.
Thank God someone explained this better then anybody!! Give this man a promotion!
Damn it...the price of Kona coffee is going to skyrocket!!
No it won't, Kona isn't near the volcano it's on the other side of Hawai'i island the coffee's all good
Thanks for letting me know. I can't regularly drink coffee, so I buy a bag of Kona beans for those times when I give in to the temptation.
If you want to taste what Kona from 20 years ago tasted like, go for Panama. Trust me.
Liz Tukenmez do
Too funny!
Because it's a volcano
Very clear explanation. Thank you
Great video with understandable information.
That whole neighbourhood will very soon be TOTALLY UNINHABITABLE. . So sorry..so sad..
truth seeker---temporarily
for a second i was like why is she using metric system terms? the i noticed it was a Canadian channel. :D
Geologists use the metric system
Bob is very smart. Great way to explain whats going on and why, and not using fancy words noone understands.
Nice report. Just wanted to clarify, the video that shows the grey ash clouds and the deep circular lava pit are taken at the summit crater of Kilauea which is actually 20 miles west of where the fissure outbreaks near the coast are. The lava that is spewing out is from the underground lava system which would normally be pooling in the main crater's vent. In late April the lava began draining from that main vent and began moving underground toward where the current volcanic activity is occurring. Initially the scientists thought the lava would exit at the Pu'u O'o vent which is about halfway to the current activity. This vent was really active from 1990-2014 with many spectacular lava flows to the sea. The sensors actually indicated that Pu'u O'o was filling with lava , but in a short time it became clear that the lava was moving on, and it must have surprised people when the fissures opened up in early May in Leilani Estates. Many have questioned why a geothermal well and residential neighborhood would have been built in an active volcano zone. Actually, in that area, the last eruption was in 1960 in the town of Kapoho, which is the region that is the farthest eastern tip of the island. Exploratory drilling for the geothermal well was done in mid 1970 as an alternate energy source during the time of high oil prices and gas rationing (1975). The unpopular venture was monitored for nearly 20 years for feasibility and stability and must have been deemed safe as the power plant was built in 1993. Leilani Estates must have used the geothermal project as reassurance for building there and actually the last lava flows in that area were in 1955. I actually watched that from my grandma's house. Anyway the decision to build there has just been shown to be a costly unfortunate gamble. One last point. Bob's colleague was concerned about the large boulder explosions. That is actually a concern at the Main summit crater which I already pointed out is 20 miles away. The mechanics of those explosions are like this; as the lava drains from the main vent toward Leilani Estates the level of lava at the summit will fall below the artesian water table level. The walls of the main vent will be collapsing in on itself and act as a debris plug. Meanwhile the water flowing into the vent will build up steam pressure until it is released as an explosive ash cloud eruption and the process will continue until the lava level rises to cut off the water source, So there is water involved, but the volcanoes Bob mentioned Mt. Etna, Herculaneum, et al, have debris plugs that build up over many years and are more massive and densely packed and the pressures that build up are magnitudes more powerful and also contain explosive volcanic gasses so they are much more violent. Also the lava in Hawaii eruptions, we call pahoehoe (pah-hoy-hoy) is more fluid and release any gas or steam pressures easily as seen in the fountaining at Leilani Estates. So deceptively beautiful.
Look at the Hawaiian chain , that is a crustal hot spot, it has been erupting for millions of years.
Why all the surprise, Hawaii is all volcanoes, all the way to Midway.
Michael Clark actually the chain goes to Siberia
not a crust, we're in the MIDDLE of the Pacific plate
Michael Clark If you look at Google earth you can see remnants of Hawaii all the way up to the Aleutian island chain in Alaska or perhaps Russia. It's incredible.
Yes indeed it is, that alone proves the tectonic plate theory is true, the pacific plate has been moving for millions if not billions of years, the hot spot is stationary.
Follow Dutchsince on CZcams!!!! He can explain this better. Also last time the volcano drained it caused that earthquake in Japan as well as the tsunami.
Can Bob get his own show? I like the way he explained things.
Wow! Thats cool
it is a volcanic hotspot caused by the impact of a rock or chunk of iron hitting it creating a permanent vent
There are only two hot spot origin theories that are currently accepted as plausible by majority of the scientific community. None of which are even remotely similar to what you just spewed.
Blame it on Trump
Great information !
He was one of the best to speak on this topic! Bravo!!! 🙌🏽🌺
The thing that gets me is that they've known for a very long time the direction of the plate movement so why would you build complete housing developments and towns where you know it is going to erupt sooner or later. This makes zero sense. That whole side of the island should have never been developed.
Richard Crockett - Neither should have the west coast, earthquakes. Nor the east coast, all those hurricanes. Let's not forget the mid west, can you say tornado alley? There is no place on earth that is safe from natural forces.
While what you are saying has some truth it's not the same. Those are all huge maybe's but this is a sure thing. The Volcanoes of Hawaii are very predictable. The eastern rift zone they build all of this inside of is called that because they've literally known for decades that is the path of the hot spot under the island. The only other areas on earth that has a similar situation would be river flood plains like the Mississippi. At least there they have the excuse of the extremely fertile land for farming however. This was just greedy land developers trying to sell a little slice of "paradise" for the greatest profit.
Richard Crockett - What about California? They have subdivisions built right on top of fault lines and they know there is going to be the BIG one someday. Then you have people that build on beach front properties on the east coast and they KNOW they are going to get hit by a hurricane. So there is no true difference.
HackTheTruth I'd say the safest place is texas nothing happens in texas
Insurance
I hate to repeat the other comments but, isn't this volcano doing exactly what volcanos do? Erupt an spew lava every where!!!!
I like when he explains how it erupts really creative I'm dumb and I still understand his explanation. 😘
Usually you don't learn much from the news, this time it's otherwise. One simple word: Fascinating!
Hawaii is part of phillipines before and also Guam
Because of Lava
Man, been loving Bob Macdonalds fast paced enthusiastic practical explanations since I was a kid, he’s still the best science correspondent I’ve ever seen in tv. He actually explains what’s going on.
Thanks For Keeping It Real 💯💯💯
Why Hawaii keeps erupting? Because of ILOCANOS not Pilipino!
Maybe pink floyd can play a gig here great images for a music video
The best explanation ever to understand volcanic movement
He's soo excited! He's like a little kid Lol
Well as David Bowie Said "Under Pressure!
The outside weight of the earth cause extreme heat in the center of the earth. Liquefying rock that looks for escape in the weakest parts of the Earth.
Prisoner Zero Earth is flat bro.
Ok the thing this guy is saying is not entirely true. Volcanoes don't blow their tops b/c of water. It has everything to do with the composition of the molten material. In the past the volcanoes with sever violent intensity had a much higher composition in silica, making their material have the consistency of tooth paste, thus making them rather gunky and viscous. The Hawaiin volcanoes are indeed from a hot spot, however the magma composition of their volcanoes are ultra mafic to mafic. Meaning it has low silica and thus less viscous, its lava flows smoothly, that's also one reason why cooled lava flows look like rivers of rock. Yes it is dangerous. Also Krakatoa was not mafic. It was either an intermediate or phelsic volcano, which is why it was so violent. The Hawaiian volcanoes do not have that extreme in violent intensity. Also I'm studying geology so I may not be entirely true but him saying that it'll blow up like major volcanoes in the past is false.
This is just a tid bit of info if you care to read.
do you watch Terral Blackstar?
True - mafic vs siliceous magma composition has the greatest effect on a volcano's explosive nature. Krakatoa, in particular, though, is attributed to seawater seeping into the volcano and coming into direct contact with the underlying magma while it was still at depth and under full pressure. The combination of steam explosion and subsequent full-pressure eruption of gas-charged siliceous magma was what gave it such power.
Sophia Ballas of you listen to him, he was saying that this volcano would NOT be a violent eruption.
And your qualifications are?
•sees video•
•looks out side•
•Sees fire•
Oh shi....
easy to understand explanation as to why Kilauea is/was different from Mt St Helens, Vesuvius, Krakatoa, why it keeps magma bubbling nonstop.
Anyone see Red Skull at 0:10?
It is human nature to look for faces
demon awake in hawaii
YES
Avengers spoiler alert. He's on a different planet where the soul Stone was.
it`s actually Homer Simpson if you pay atention , and he`s on fire ! :D
I hate the term Mother Nature
Great report. I'm so glad he said thousands of years and not millions of year. Great job!
That looks so cool.
Why are these people so excited about it? People are weird
it's very exciting
crb129_ because liberals love destruction
I mean...it looks pretty cool o.o
it's Freemasons aka false Jews Zach Hubbard covered it on freetofindtruth.com
Most Hawaiians are proud cuz Madame Pele is cleaning house and she is taking back her land 🙂
The lava is awesome to see but it’s not unusual. The news is sensationalizing, this event. No one has died and really very few houses have been destroyed compared to other natural disasters, so it makes me wonder why they so focused on this. Are we trying to hide some other more important news or is it just a slow news week.
Trying to distract from the fact they claiming new land that has yet to finish forming!😂😂😂💀
At last an explanation into the science of Kilauea that makes sense and is easy to understand just whats going on
lived on the big I for 6 years. great times .. great people
All these people saying its end times. Brah I guess when Oahu was created 3.5 million years ago it was the end time then too huh? Then when Maui was created 1.5 million years later, it was the end times then too huh? Wow... if i keep going back, all the way to the beginning of time, it was also the end time. So the beginning was the end! Its not end times, it time for Kiluea to create more land before Hawaii goes inactive. All this end times herpa derp.
Sadly these people always say this crap when something like this happens
FOR REAL, just waiting for History Channel Shenanigans.
Tell me about it. How can it be the end times when I am witnessing creation?
the earth is just a little above 6000 years
Annie Harford I really wish you weren’t being serious about that statement but something tells me you really think that.
Please don’t breed.
I blame this eruption on Donald Trump!
Kevin P I'll blame you every single time my hot pockets still cold in the middle.
Do you know if the town of PU 'NANI is safe from the lava flows?
Kevin P no idea hun, just commenting bored x3 recently started checking into this.
TheNakedRamen you do know what PU 'Nani means right?
This volcano will Make America Great Again.
Why do all TV reporters ask a question, and then interrupt the answer halfway through?
If he was my teacher I would have probably paid more attention in school!
It's GOD dun dun dun lol jk it's natural
Julian James God is a figment of your imagination
Nature is God, God is nature. God punishes those who disrespect it.
IndigoAurora No
IndigoAurora But whatever you say buddy
Hopefully this doesn't turn into one of those comment threads that argue about religion and end up getting no where
Why does the Hawaii Kilauea volcano keep erupting?
It's man made obviously
The lava lake has already receded below the water table and the sea level.. they're waiting for it to Cork itself build pressure and explode
I hope everyone is ok
It demands a sacrifice... let us lower Justin Trudeau in very slowly.
tehjamez lmfao
All the swamplings would fill IT UP!😈
Jon Nan and the NRA lobby too, got to be fair now.
Pele
Andy Holliman there is no such thing..it’s just a myth
Johnny, If you lived in Hawaii, you would know better than to make a statement like that.
Pele is a idol that will parish along with all of Hawaii for their idolatry. The cites of Sodom and Gomorrah were not spared
Best video. Finally
Actually you can still do the hikes on Kilauea, and the national park is still open for everyone. I'm going there in just a few weeks and I don't expect there will be any problems. It's really just that little area near Leilani Estates that's the problem. My mom is from the town of Volcano, 10 minutes from the national park and the main craters, and everyone there is just living their lives like normal right now.
Gigi Noelani the National Park closed today indefinitely
Lincoln Riddle Oh dang. The whole park? Just today? But people in Volcano Village aren't at risk right?
Gigi Noelani most of the Park is closed indefinitely. They think there may be an explosive eruption at the summit in the coming days, which is why they closed the park
It almost seems like there is an increase in seismic activity as solar activity decreases. Will the CBC address this? *spoiler alert* No, not at all. This video is funded, in part, by my tax dollars.
Christopher Windsor of course not they always roll out these fools who think they have all the answers..god calls them fools
maybe its just not news worthy at all...most likely because your not a journalist or a scientist.
toknowandgrow *you're
toknowandgrow You may not be an astrophysicist yourself.....
Then I will leave it to the professionals...and not pose quasi hunches as proof of CBC deceit on a topic that may have zero relevance.
I hope the lava gets that dudes teeth.
Nicholas kent lol
Nicholas kent For some reason
You made me laugh, which I needed
I noticed that too but I didn't want to say anything! I'm glad you did.
thanks for explaining how the Volcano works
This scientist loves what he does, it radiates from his soul. Very passionate and moving talk
Because the Island is tired of the liberal crap.......Lol
wrong
Go figure, nothing intelligent to say from a republican.
Jerrymc1975 - Your not even worth an arguement!
Thank you! #MURICA 🇺🇸
Jerrymc1975 why get offended at a joke?
Freaking Trump
People in this clips look happy
This guy just makes so much sense when he talks...
Stop using metric
2.6cm =1 inch, there does that help
All serious professionals use metric.
Someone tell that lady this is America. We use imperial measurements.
David Fultz the feed is from a Canadian news station... Not the USA
Brian Landers same here! It doesn’t hurt to learn something new either. David Futltz open your mind. There’s a lot out beyond your computer!
Most Canadian's still use Imperial measurements
Mainly due to the fact most Americans aren't smart enough to switch to a better,more accurate system of measurement...and a bit of arrogance
Bub Dog's What do you think? Not true
My homie Kilauea is going through a lot right now, take it easy
Kilometer, a metric unit of measurement equal to 1,000 meters (approximately 0.62 miles).
Mother nature my foot. The wrath of God.
Amen sister
Debra King truth be told!
Yes. I agree. The beginning of the end. Widespread hatred and vitriol. Why are ppl surprised?
The cities of Sodom and Gomorrah were not spared for their idolatry why should Hawaii be spared. The pray to Pele. let's see if Pele saves them
Yeah, because growing coffee, Macadamia nuts, papayas, and, other crops, enjoying the sea, and beach, and raising your family in a gorgeous island setting is so, so very evil...... If this is the "wrath o` God", shouldn`t Vegas have fallen into a sink hole by now? Grow up, it`s called Geology...We have actual science now, it`s OK.
that guy sure loves to hear himself talk
AND he's got it right
Who held a gun to your temple, and made you stay, and watch? Exit if you don`t like it. I for one like science content.
"The Day The Earth Stood Still". Love it. (Over McDonald's right shoulder).
That is terrifying 👀☄️🌋...no casualties thanks goodness as mentioned in the video.
