I always remember learning just how awful volcanic ash is to your lungs, it has a similar composition to cement in powdered form, when it's breathed in it reacts with the fluids in your lungs turning it into a version of concrete, you would drown in cement as your lungs collapse, so if you find yourself in the position of watching volcanic ash falling around you, go inside

To add on, burning farm land and spreading ash has been a practice used by many farming communities known as slash and burn. It makes a field called a swidden for a few months or years but eventually it grows back because the ash from burned trees and plants gives tons of nutrients to the soil. It allows for better grow seasons and helps negate the need for GMO’s. I hope tonga has a strong recovery from this

I know you only mentionned this as an ad, but for whom might be interested. The Santiaguito in Guatemala is one of the top 10 most dangerous volcanoes on Earth. It has, as you mentionned, only existed for a little more than 100 years. The breathtaking view you mentionned was taken from the Santa María, the volcano that was the main one. Its lava was very viscuous and dried quickly, which closed its crater down pretty deep. Upon an eruption, a hole was opened next to the Santa María: the Santiaguito was born in an overwhelming, destructive eruption. It shattered the Santa María's flank; the damages are still evident to this day. The Santiaguito kept growing up since then, being almost always active. If you ever go to Guatemala, and wander around Retalulehu, Mazatengo or Quetzaltenango, you might see the couple volcanoes: a big, broken one, and a small, active one. My thoughts go to the victims of the Tonga volcano.

[@TheRisskee]

I was in Guatemala in 2013 and I only found out about their volcanos once I was home and it bummed me out that I didn't get to see it. Although, we did go to a resort town on the edge of a crater and there's islands in the middle where people live and work. That in itself was cool but it's not like seeing an active volcano.

[@Muonium1]

Important to note that while a shock wave - by definition - travels faster than the speed of sound in that particular medium, what we see on the satellite image is not a shock wave. It's just a pressure wave and is traveling at the speed of sound. The initial explosion of the volcano, just like a nuclear detonation, did indeed launch a shock wave into the atmosphere, but shock waves dissipate and slow down rapidly as they propagate, and even by the time it reached the local islands some few tens of miles away it was certainly already a pressure wave traveling at the speed of sound and not a shock wave any longer. Also, while the total energy of this explosion was definitely greater than any nuclear detonation, the peak power was certainly not, with an H bomb reaching vastly higher powers due to the reaction taking place over a mere microsecond or so while a volcanic eruption takes millions of times longer to release its energy.

Thanks for pointing this out, particularly about the time taken to release the energy. Few videos seem to mention that the satellite images are 10 minutes apart.

what f amazing vid I'm not normally a volcano person but you made it sound ver interesting thank you so much!

[@RomboutVersluijs]

Pretty sweet video again! Really well done and like how you showed comparison as how big that closed was compared to Europe. Really show perspective

[@Kaatamarii]

I can just hear my old college Geology instructor cheering in excitement in his chair.... He REALLY likes volcanoes-- he even used all our birthdays to see who had the most impressive explosion and favorited that student xD

[@mandelbro777]

Great video, but the image you have shown of the land bridge (central cone above seal level) having been blown away, was actually how it appeared after the 14th January eruption, when most of that mass actually collapsed into the magma tube/chamber (some being ejected in the initial ash column). This collapse was the harbinger of the final 15th January eruption which produced the shockwave (seawater leaching into the collapsed section, initiating a very rare steam explosion event >24hrs later). As a result, the two saddle like islands are now almost gone, and there's no ash fill above sea level at all around that central cone which was totally obliterated. Hunga Ha'apai is now just a small rocky outcrop above the water. Great video though, as usual :)

This was really interesting to watch! Thanks for making this small documentary!

[@TheInvertedFollicle507]

The Mt Tambora event in Indonesia (5th April 1815 - 23rd April 1816) was the largest volcanic eruption recorded in human history was the most recent VEI 7 scale outpouring of magma, ash, pumice and other such material. It created the loudest noise ever recorded - apparently it could be heard 3000 miles away.

[@rachelectroDC-84]

I've been fascinated by volcanoes since I was a child, and Tambora was always such an impressive monster of a volcano. Another entire island just gone, and most of the globe having "The Year Without a Summer" as a result of all that ejecta. Unreal.

[@IDiggSocialMedia]

Krakatoa in 1883 made the loudest noise ever recorded!

[@TheInvertedFollicle507]

@@IDiggSocialMedia Well really it's subject to debate. Back then they didn't have the advanced audio monitoring and recording equipment we take for granted today so all people could do at the time is gather witness statements and the like. Naturally that will lead to conflicting views.

[@sabishiihito]

@@TheInvertedFollicle507 as you said, the tech to monitor the sound didn't exist when Tambora went up, which is why the Krakatoa eruption's sound is the loudest noise ever *recorded* by humans. Not necessarily the loudest ever *experienced* by humans.

[@TheInvertedFollicle507]

@@sabishiihitoah dumbass me OK I'll take this loss you win lol yeah you're right. I wonder which one was in fact the loudest? 🤔 🤔 🤔 Edit I may have in fact meant the loudest sound ever recorded by human ears though in all honesty I don't remember.

This is awesome! Thanks for sharing, my friend!

[@DaveBegotka]

Great vid! Thanks for identifying the correct footage of the eruptions too many here on youtube are using the smaller eruption footage for click bait of the big one

[@soldiergal17]

Lived in Xela for about a year and loved seeing that little volcano spewing ash everyday. It was always a cool sight to see.

[@mgmcd1]

This eruption will have an effect on ground based astronomy for a while. This was good coverage of this event. Thanks for not dumbing it down or sensationalizing it, as has been done in other videos and on TV.

[@stevie-ray2020]

Despite seeing a number of videos on this event, this is the first to include infra-red footage of the shock-wave, so a great production! Also hope the Tongans receive the aid they desperately need without introducing Covid-19 into their communities!

[@Teramis]

What an *excellent* little documentary. And terrific graphics as well! Especially liked the 'water on Mars' simulation. Thx so much for doing this.

[@isaiahwright4536]

My birthdad was Tongan so I always get worried about the Polynesian community. Especially with Tonga so when I heard about this I was terrified. Thank you so much for the amazing video

[@lwilde]

An excellent presentation Alex. Keep up the good work! Astrum never fails to provide interesting videos. Thanks.

[@michaelcoughlin3013]

I remember when Mt. Pinatubo erupted, it dropped global temperatures by 1F. This gave the US a cool Summer in 1992.

[@zoomerboomer3109]

This eruption in the long-term is probably going to be quite a significant one scientifically due to just how unusual it was. Thankfully the eruption didn't take to many lives, soon enough Tonga will recover. Great documentation btw.

[@brianwilson9501]

Finally found the data I was looking for in this. Thanks for the great and informative video.

[@phoenix042x7]

And finally someone who did not misrepresent the viral footage from the ship the day before and tells the truth about the fact that it was a relatively tiny eruption the day before compared to the one caught on satellite the next day. Kudos for that. Honestly one of the better researched videos on this out there.

[@bodymotionchile]

Here in Chile, we got the tsunami warning in our cell phones for all the people living in cities/towns/etc close to the ocean. Only one Island at the south got a minor tsunami but enough to destroy a bridge used by local fishermen. Also in Perú 2 people die bc of the flooding

[@S-T-E-V-E]

I can't believe the geologists working at the Volcano did not capture footage of the eruption or have any seismometers set up on the island! They really dropped the ball!

[@joshuapatrick682]

Everyone says this was as big as Krakatoa but Krakatoa literally Dropped the average temp of the whole Planet for several years.

I love watching different people with this kind of information, bc some explain more than others, in one way or another

[@aimeevanlandingham3844]

It would be awesome if you did more videos on volcanos as you make them the easiest to understand. You actually filled in the gaps that everyone else seems to be missing, like what the island looks like now.

[@davidford3115]

I agree, though on a sister channel to Astrum, maybe under the name Gia or Gaia?

If you'd like a channel that does very good volcano videos, I recommend geology hub :)

[@pistispistis1524]

We live in the islands of Fiji, the eruption can be heard from where we live, and with that, we faced tsunami's.

[@brian4872]

Hi Alex, great video. I have a note on the picture you have used @7:40 as this was after the first eruption. The second massive eruption removed even more of the island!

[@Flyineddy]

I was about to mention this as wel. Currently almost the entire island(s) is gone.

[@charlesdarwin7253]

I just can't believe that an identical volcano erupted in Luxemburg at exactly the same time. That's a rare coincidence to witness in one's lifetime.

[@johnmackenzie3030]

I loved you overlapping it over Europe - it gave you the perspective!

[@NHR_Music]

I love to see stuff like this. Seeing our planet be ecologically active and changing with it's landscape is something that's hard to imagine when it usually happens slowly across millions of years but this only happened within a few years (the islands connecting into one and then the explosion happening).
