Tsunamis and shockwaves hit continents on the other side of the Pacific. The Hunga-Tonga Hunga-Ha'apai (HT-HH) volcano was like a massive shotgun blast from the deep, generating the biggest atmospheric explosion recorded on Earth in more than 100 years.
__
Funded by The Nippon Foundation, NIWA and SEA-KIT surveyed over 22,000km2 surrounding the volcano, including mapping 14,000km2 of previously unmapped seafloor as part of The Nippon Foundation GEBCO Seabed 2030 project
New Zealand's National Institute for Water and Atmospheric Research (NIWA) has discovered that almost 10km3 of seafloor was displaced - the equivalent to 2.6 million Olympic-sized swimming pools and a third more than initial estimates - with two thirds coming from the summit and the rest from the surrounding flanks.

I live 220km from the eruption. I heard a massive crack bang whilst eating lunch at the table at home. Then another and another. This went on for what seemed like well over an hour long. And the recent earthquake in Tonga sounded like freight train was coming before the house shook very violently then started to roll. Both experienced have really opened my eyes.

@karlbrundage7472 Год назад

I have the Suspicious0bservers Disaster Prediction App on my phone and not a day goes by that the Tonga region doesn't experience at least a Magnitude 5 quake. As the site creator, Ben Davidson always ends his videos: "Eyes open, No fear... Be safe, everyone." Were I you, I'd be prepping by stockpiling food, fuel and medical supplies. If you live in a low-lying area that may be subject to a tsunami you might want to outfit your vehicle with survival equipment, including food, shelter, trade-goods, personal defense, etc. and be ready to evacuate to high ground on short notice. If you don't currently have a weather-alert radio get one and have it set up. The next mega-blast eruption might happen at 3AM local time. You are in my prayers. Be safe...........................

Something I found fascinating about the blast wave that went round the world is that it showed up on personal weather stations everywhere I looked, including my own. The timing of the spikes recorded were proportional to the distance from the blast and, for example, it hit in a arc from Alaska to South America at nearly the same time. I used the weather underground system to research this.

@@Novastar.SaberCombat Yes. I'm in north central Washington State near the Canadian border. My weather station reported the spike of the primary wave (short path) and it showed up again from the long path having gone around the world. This also showed up in many recording weather stations, unmistakably. I was able to calculate the time of the long wave pass and when I looked at the data there it was. Same thing happens with earthquakes of sufficient size. Exactly at the opposite site of the earth from the blast it converged. There were no weather stations near that point that I could find, but it was probably a big deal.

@@vmcla NIWA, as defined in the description of the video (I know, reading is hard) is New Zealand's National Institute for Water and Atmospheric Research. As for the comments praising their great effort, there are many people interested in the science surrounding volcanoes, and the Hunga-Tonga Hunga-Ha'apai eruption in particular is incredibly noteworthy, as it is the first eruption of it's kind to occur in modern times, and has in many ways surprised scientists from all over the world. Many past assumptions need to be reassessed because of this eruption, because it turns out that before this, no one actually had a good understanding of how a big eruption in shallow water behaves. For science, this eruption is likely to be at least as valuable as Mt St Helens' 1980 eruption or Pinatubo's 1991 eruption. Which, to be clear, likely makes it the single most scientifically valuable volcanic eruption of all time. I expect it will become a 'standard' to compare (some kinds of) volcanic eruptions to much like Mt St Helens or Krakatoa (1883) are.

This eruption just keeps breaking records. I've been following the atmospheric changes since and am hoping someone does a video like this about them. I do know it pushed a huge amount of water vapor into the stratosphere and it has changed the temperature in unexpected ways. This will enhance or even change weather patterns, and may be a large player in the chaotic climate we've been seeing. But I haven't come across a thorough video that focuses on data. Hoping we'll get one soon.

Otherwise it's just people like us putting the pieces together in a logical way. However, this eruption keeps showing us that using logic based on passed experiences is the correct way to do it, but our assumptions are turning out very wrong. All I know is that the weather patterns where I live have been way out of whack. Sort of normal, but also very abnormal at the same time. I get the feeling this area is going to take a bit more time to tease out the specifics. But the atmospheric scientist have got to be chomping at the bit for more data.

My great grandfather I suspect, may have been born at a time, when fonuafo'ou ( falcon island) erupted, and was named after the volcano, I think there may be some interesting stories to discover from the people of ha'apai regarding volcanic activity, stories, they carry from their ancestors. I know for sure, that this explosion would have definitely left a huge imprint on the minds and memories of the people, and this event will be told to the generations to come. 🙂

Hereing that blast and seeing the wave in the distance was amazing yet humbling. About ten years after the first eruption of Mt St Hellens in 1980 me and a friend drove up to the observatory that late would be destroyed when the volcano had more activity. When we got there, we were amazed to see people walking down a path and into the crater. As we did not see much activity and the seismographs where still, so we both shrugged and went for it. I got to put my hand on the lava dome that years later would blow itself apart. To feel the heart beet of the planet was life changing. In a touch I could feel just the smallest portion of pure power that is our great planet. It was Awe inspiring and gave me a new appreciation for the power we all walk on every day. I prayed for the people of the Islands when the eruption happened in Tonga and was so sad for their losses. Bless and be well all.

One of the most spectacular natural events on Earth in this century, this is for sure. One can only be glad that this happened far from human habitation. The Campi Flegrei caldera has a similar risk profile due to its size, its instable geological environment and a similar involvement of shallow water. The Aegean is a similarly dangerous area, as indicated by the Bronze Age eruption of Thera which was also similarly violent. Good for the inhabitants of these areas that such a warning shot happened, now they will probably assume that their situation is several magnitudes more dangerous than previously thought and conduct a lot more of preparation.

I was shocked to see the Mt Saint Helen's eruption and devastation. It stands to reason this world happen in the ocean as well. I am still grappling with the scale of the impact because I only see the cean surface and the subsurface grid lines. The results of your study should be fascinating.

Fabulous work ! The narration was buried by the “background” music. On my ipad . From time to time.

Great works and investigations. More planning and emergency strategies are needed to help Tonga. NZ , AUS and Japan when another quake or volcano like just happened in Java.

Thank you for the video, does anyone know who made the music starting from 1:18?

Riveting. Great work all.

People are confused of the scale of the eruption. I think it’s because it happened in the ocean which doesn’t give people any items to scale it with other than the ocean itself, but the ocean is massive. So it makes the eruption look small. If people saw it next to a city or with cars driving nearby they’d get a far better understanding of the scale.

I live in Alaska and it was the weirdest feeling and sound when this happened. My cabin felt like it was shifting in slow motion and my cats were totally freaked. I had no idea what it was 🤷‍♀️

someone where i live has a weather station and that recorded the pressure wave going over his equipment here in the uk.

What's rearly happening ? Keep up the great jobs 👍

@GraveTender333 Год назад

did they take water samples near these events? I wonder the differences from sea water far away...

They said at first that it was a mere vei4 or so, I mean not here in this documentary, but scientists the months after the event. But when you see the blast from space, it is pretty clear the cloud is the size of an entire country! When I saw the size of that thing, I couldn't help but think about Yellowstone or Campi Flegrei or Taupo. It's a behemoth! A once in a lifetime event is an understatement! I now believe, explosion itself was as big as a supervolcanic eruption, but it did not throw as much tephra as one of those (actually, it was far, far lower volume). Just that given it was undersea, that reaction of magma and seawater made it blow with a supervolcanic force, without the massive tephra volume a supervolcano would spew.

What was the safe zone from that Jan22 eruption? 50km would have been too close?

The science and equipment used to study and understand this volcano is outstanding. In watching this video, you feel like that you are there. Science, you've got to love it! 🙂🌋

Fascinating stuff. I have one question that no one seem to be able to answer, Why did the pressure wave go around the earth & not just laterally out into space? And surely it must have gone as high as it went laterally?

@HankHillspimphand Год назад

Need more of these types of documentation on video, than a paper published that while seen and important doesn’t help convey why these expeditions are important.
