The eruption from the Hunga-Tonga volcano in Tonga on January 15th was enormous, causing a tsunami across the Pacific, an ash cloud that extended 20km into the atmosphere, and an overpressure wave that went around the world. This video examines the impact of the eruption on the atmosphere, and explains why it seems to have caused a world-first observation of a volcanically induced meteotsunami.

Looking why the Tongan eruption on January 15th was so unique, the impact of the Tonga eruption on the atmosphere, the Pacific tsunami from the Tongan volcano, and the unprecedented meteotsunami that was detected in the Pacific and Caribbean. Really this video is about ocean-atmosphere dynamics, and how the planetary fluids of the Earth's atmosphere and oceans can interact to produce amazing results. If you like videos from Smarter Every Day, Veritasium, PBS Eons, Crash Course, or Sci Show you will enjoy this interesting video about the Tonga eruption and tsunami.

Simon, I think you did a really good job of communicating the interesting science while also exuding empathy and concern for the people of Tonga. It's also quite commendable that you're donating what you receive from the sponsorship!
Hey there... thanks.
czcams.com/video/CN4gWyvje8w/video.html
Yeah he did. Great video
Thanks for your positive comment!!! I love to see ppl treating each other like that!! Love you, be safe in our world
I originally read that as excluding and was freaked out.
I'm always surprised when Mt. Pinatubo's eruption is brought up-- I didn't technically live through/ experience it, but my mother was pregnant with me when she was evacuated from the area. I know it was significant scientifically & historically, but since no one else I've ever personally spoken to was around that area it feels like family history more than world history, even if that's completely illogical.
I find it fascinating that a shockwave and ejecta plume so colossal can have so much less volume than eruptions like Pinatubo or Krakatoa. I guess it really goes to show how important the length of a volcanic eruption is as well as its sheer initial explosion to its impact on climate.
"They" are simply lying about the size and impact of the ejecta because it will completely erase any threat of global warming. Prepare for a mini ice age, when ppl find out, the store shelves will be empty.
@@bkwillia78 hahahaha what the fuck
The Pinatubo eruption went on for days, this one was only for a couple of hours.
@@Pete856 yeah exactly my point. It can feel a bit counter intuitive is all
Another big factor (from what I heard) is that most of the plume was actually steam from the interaction of ocean water with hot rocks and magma. So it really was smaller than it seems.
I would really like a video on biomass wood pellets and their environmental effects
I'll add it to the list!
@@SimonClark sir, I would recommend a video for the newbies about how computational physics helped you and has helped in geosciences over the time. Like in a broad way.
Just Have a Think has a video on this subject and provides sources if you are interested. It's called "The Biomass Scam."
I would like for you to pull my Finger, after i Drink a Pallet of room Temperature Mayonnaise.
@@SimonClark Can you do a video on holograms?? And I hope you can respond to my other comment about how to deal with all the math in grad school. Thanks and hope to besr from you.
Dude I was about to sleep, 5 am in my country and you upload this interesting video.. Dammit Simon!
Got to sleep! It will still be here in the morning :)
(well, later in the morning)
@@SimonClark I hate you, but I love you, and your videos btw, have a great day!
@@JCAbarca go to sleep.
This is not volcanic Mother Nature thing, this is man made claim for dropping a bomb on volcano
The Earth literally just farted.
Or at least part of it did..... And the other parts said "Was that you??"
People died Alice
This is not volcanic Mother Nature thing, this is man made claim for dropping a bomb on volcano
Its tonga time😔
There goes my hope for a single positive thing after that eruption.
Lots of interesting science yet sad humanitarian disaster things to learn about in this video. Good job Simon for covering the science, and stay safe there, Tongan!

This fluid interaction between the atmosphere and the oceans is fascinating, I've never thought of it like that! Thank you, keep it up :D
I just now stumbled on this video and am now subscribed to your channel. Pretty awesome information on the Hunga Tonga- Hunga Ha’apai volcano eruption. I hope there’s no repeat of what just happened to Tonga. Thank you for donating to help Tonga! Mālō ‘Aupito e tokoni. Us Tongans appreciate you! 🙏❤️🇹🇴
I did not know meteotsunamies are a thing. We truly live in a fascinating time where we have access to such large wealth of data
So interesting, thank you Simon!
Your enthusiasm and curiosity is contagious
Well done, you did a great job explaining the science behind this tsunami and the various impacts.
Thank you for the explanation and use of graphics / satellite images. Good on you for donating the funds.
after the incident, i was waiting for your video. there is a lot of misinformation about this out there like people claiming it was a "bomb test" and stuff
I FOUND THIS MEGA COOL but also double points for spreading awareness on the subject, hopefully a lot of us can donate!
Earned my subscription with your generosity. Well done sir!
P.s the quality of information was great as well
I had to double check that I was still subscribed because I totally missed this video when I saw it in my recommended today. Then I checked your channel and saw I'd missed all your videos in the last 2 weeks too! CZcams really needs to step up their recommendations game, I'm missing QUALITY content here 😤
Great video and science communication!
I really appreciate your elaboration and love on fluid dynamics!
I really loved the video and the animations used. You won't believe but in my childhood I used to have visions like the animations shown in the video. Thanks for making it true ❤️
Re: the meteotsunami @6:54. It struck the islands in the Caribbean BEFORE the ocean wave struck the west coasts of the Central American countries to the west of those islands.
The atmospheric shock wave traveled faster than the oceanic wave, so it reached the Caribbean islands before the oceanic tsunami did.
I’ve watched videos talking about the volcano and tsunami but not the atmospheric effects. It’s nice of you to also donate to the relief in Tonga.
Fascinating insight, and very well explained. I certainly learned something from this video👍
That was very informative. Thank Simon ^-^
Video suggestion: followup to this... What would have happened if toba volcanic eruption of 1810s occurred now
Hello Simon, we are mostly okay here in Nuku’alofa. I had the chance to observe some of these fluid dynamics 1st hand as I was able to view and film the eruption from my lounge window, now we have the internet back online it is very interesting to learn a little more about what happened. Thank you for the video.
I've always been fascinated by super volcano eruptions and having all of the observations related to this eruption available really helps put those eruptions into a perspective that we never had before. Thanks for adding another fascinating facet to it with these meteotsunamis.
Yes, it is actually really amazing! Sad that it also had and still has its victims. Thank you for the explanation.
Simon, I see your book on the shelf and I am sooo excited for it to arrive next weekend !!😀 😄
Great vid Simon
Science is amazing! I was intrigued about everything in the video, including how your hair went from tidy to chaos at 9:38.
The severing of communications with these tiny islands is uniquely scary to me. I don't really know why but modern communications are so central to me and my lifestyle that it is basically unimaginable to be in such a catastrophe and unable to communicate with anyone outside (or even look up survival tips lol).
I just came across your channel!! Well done ❤️ enjoying from Conway, NH, USA ❤️🙏✌️
I live in a town that ocasionally gets large meteotsunamis. The biggest I've seen (3-4 m) almost dried up the port, then flooded everything around it. Our word for this phenomenon is 'rissaga'.
Thanks for enlightening us on a new phenomenon
New subscriber, I enjoyed the video and your approach to science. Thanks a lot Simon! From 🇨🇦
Good on you for donating the sponsor money Simon
Good explanation!
Thanks for the situation assessment as well as the sweater choice, both of which are very interesting.....
A youtuber named Soane Gallaher has been posting Tongan videos of the damage. It looks like some islands have had to be evacuated and abandoned because everything was destroyed by the Tsunami and the ash contaminated the water. The entire country has either been severely damaged or destroyed.
reminds me those weird californian dew attacks from a couple of years ago
I think the fact that we can actually measure it is more amazing than the fact that it actually occurred
7:38 That's basically me telling my friends about stuff i learn from youtube
Thank you, very informative. My son lives in Tonga and was there while it was all happening. He loves science. Im sure this event will further trigger his interest in the topic. Amazing! #livingscience
Seems that it could possibly be a common occurrence in the overall scheme of things considering the number of years that volcanoes have been erupting that we not observable, hence never noted or recorded.
We've only had the ability to observe and photograph anything for a short period of time, compared to the length of time that volcanoes have been erupting. So while it's impressive to be able to observe and record these things there should be an asterisk to any claim of it having been an *unique event.
Hi Simon, maybe you could do a video about soil degradation and its effects on climate change. I feel like that’s a topic that’s not talked about enough. Anyway, keep up the good work!
Didn't know Tonga was ihit by a tsunami.
Thanks for the video, it was interesting.
So what your saying is that we PURPOSELY detonate Yosemite so we can all live a little bit longer.
Did I see a book in the bottom right corner with your name on it? Did you write a book? Is it out this week?
Not “just” amazing but THOROUGHLY fascinating!
Now, that info added to it any microns that are logistically fluidic!
I was expecting clickbait with this one, very happy to be wrong. Fascinating video.
The reason we don't hear much from Tonga is bcoz the island is a symbolic country with most of it's people and politicians residing in Australia or New Zealand on foreign aid.
Greetings from Colima, Mexico.
Really good video and amazing to witness.
I live in NY, and around 2am, it was a quiet night, nothing happening really, all of a sudden I heard a wind gust so powerful it made my house shake like a 65 mph gust of wind. Then there bizarre weather temps just fluctuating up and down over the next few days even for January…I still can’t believe a volcanic eruption kilometers away was the cause of it.
Whoa! (Won a sub👍🏼)
Is it "My Funny Valentine" or "My Metric Valentine."
2am New York time is not when the pressure wave arrived. More like 10am.
This is not volcanic Mother Nature thing, this is man made claim for dropping a bomb on volcano
I have seen reports of it being detected here in Poland on a mountain peak called Kasprowy Wierch.
Part of the Island fell down into the Caldera that the island sits on the edge off that caused Tsunami
From memory the atmospheric pressure wave from Krakatoa went around the globe some 7 times.
The tsunami it created even reached England but by then it had shrunk to only a couple of inches high.
You pronounced tonga beautifully!! Thankyou!! How ever it is nuku a lo fa .... the capital of tonga
We do love our recording sensors
How amazing I hope the sailing ships were fine
Sulfurous acid (H2SO3) not sulfuric (H2SO4) when water and SO2 react
I was expecting you to talk about the gravity waves' concentric rippling caused by the Tonga eruption.
Your reaction - science plus relief donation - seems okay to me. Thank you for the video!
Relevant question;
How big of a meteotsunami would the Hiawatha crater explosion have created, and for reference,- how big would the Chicxulub one be?
I was in Valparaiso Chile that day, suddenly all our mobiles started ringing. Yes it was a "Tsunami" alert due to this Tonga volcano 🌋 Police didn't let anyone to enter beach for rest of the day... Good that it just ended with minor tsunami 🙏 Thanks to this technology for letting us know hours before the tsunami . In Peru, lack of alert lead to few loss of lives.
This happened on my birthday~
That shockwave pattern looks somewhat like a single heart beat on an ECG
Amazing indeed
Finally put notifications on a channel.
I re-played what he said after saying "pressure gradient" and I can't make out what was said.... he also mentioned something like "metio tsunami" and I have never heard of such a thing before.
Look up "meteotsunami"; essentially a kind of "false tsunami" created by extreme weather as opposed to geological activity like earthquakes or eruptions.
This video is the first I've seen of a volcanic erupton! Damn nature, you scary!
I’m currently a junior in the meteorology program at Florida State University (Go Noles!). I’m in an intro to atmospheric dynamics class now but I have to take atmospheric dynamics 1 and 2 in the upcoming semesters. What advice do you have about doing well and studying for those classes?
Impressive, but I suspect this is not the first time this sort of thing has occurred, but I suspect a similar thing might have occurred with Krakatoa, but clearly then it would have been hard to observe what we can see now.
The reason why the internet cable was broken was not because of the tsunami, but because of the travel of underwater volcanic debris that traveled that far it severed the cable.
Krakatoa is proud of Tonga right now, Krakatoa shook and deafened the entire world.
A week ago get it right last Saturday
I'd like to know what would happen if this happend on land...
During the Pinatubo eruption, I remember watching a scientist claim that it caused the same damage to the ozone, as one thousand years of manmade pollution. I never bought that one, but I am sure they do some serious damage.
Hallo Simon, thank you for this wonderful work of explanation. I have a question. I have been watching carefully many videos about the explosion from the space. In some of these videos you could clearly see a second circle of clouds forming at the same time and at limits the same size of the explosion at, according to me, around 3000 km away east. I am sure you can see it too. Is there any explanation for this kind of phenomena?
Thank you for your answer.
It's a cyclone.
Mount Pinatubo also helped reduced the increase of CO2, through Iron fertilization of the oceans, helping sequestration of CO2. Perhaps the Tongan volcano will do the same thing and perhaps we can reduce the atmospheric CO2 levels using the same technique?
I think they are now saying 2 explosions, the initial eruption and then the sea falling into the lava below and then blowing up.
Combined with La Palma (and its very high so2) output I am not so sure there will no be no cooling impact. Its not going to be major but measurable for sure.
Just as Tonga announces that Bitcoin will be introduced by November a natural disaster happens to wipe out all sevices and internet. That’s gotta be some bad luck
Dumb question incoming: Is there anything interesting that happened in the antipode area when the wave bounced back? Like, was there some guy somewhere in Africa who suddenly felt his ears pop when a pressure wave hit him from all sides at once?
I can tell you that the day of and the whole week of the eruption, I felt an immense pain flair up. I get flair ups with my chronic pain on days the weather is bad, when the pressure drops, and I pay attention to that sort of thing because I have to plan my days around it. It’s anecdotal but I thought it might be interesting. I wonder how many people felt it without even connecting the dots.
Could this be a factor in 'rogue waves'?
What was the other explosion to the right of it that happened a split second before the fact
Cyclone.
I'm curious if the pressure wave was able to cause waves in other bodies of water. I'm in Minnesota so the first thing I thought of, did this cause a wave in Lake Superior? I would imagine if it could cause one in the Caribbean, it could cause it in Superior as well?
Amazingly scary.!😨😱🙆
I feel like this should have been bigger news.
Unprecedented in over 4 billion years I think not
I came here for the PhD blog, and stayed for a science I didn't know exists
@0:43 the plc in Africa where the shockwave came in from all directions. 😂
You know this had to be big if they could hear the damn thing from Alaska. That's like 5,000 thousand miles away lol.
Such an incredible force of nature here and to think we captured it all is incredible.
Not counting the loss of life which unfortunately is almost always a given.
The scientific knowledge gained from this is probably pretty significant. Gives you some small sense of what Krakatoa/ Pompeii must have been like.
The Tonga eruption clearly shows how unprepared we are in the face of any kind of natural event.
After days we still have little to no information about the situation in the islands.
Of course, they are in the middle of the Pacific, but wasn't this a globalised and interconnected world?
It seems our ""interconnection" hangs by a thread or, in this case, a submarine cable.
Most countries have a lot more redundancy in their communications infrastructure. Tonga has 100,000 citizens spread over a bunch of islands. That means
1. connecting them all is expensive
2. there's a small tax base to pay for expensive projects like undersea cables.
So they were relying on satellite phones as backup. That works in most cases. This eruption took out both the main link and the backups.
Would have liked a good, visual explanation for the meteotsunami. Wikipedia isn't helpful either.
S02 plus water makes sulfurous acid, not sulfuric acid.
It's the celestial Tiamut
May not have ever seen it before but it has certainly happened before. Krakatoa for one. Nothing new under the sun.
