Ruang Volcano Eruption Update; New Major Eruption Occurs, Largest on Record
Вставка
- Опубліковано 27 тра 2024
- One of the most powerful volcanic eruptions on the planet of the current decade occurred earlier today, sending a plume of ash to a height of 82,000 feet. Pyroclastic flows swept across large sectors of the Ruang volcano, and widespread ash and lapilli was deposited in sections of Indonesia. At least several hundred homes were destroyed or damaged by my own estimate via an eruption which was larger than Ruang's April 17th eruption.

0:49 Exclusion Zone
1:32 Tsunami Danger Concern
2:36 A Lava Dome Explodes
I honestly was a bit surprised when the tremor rapidly shot past what was observed in the hours before the plinian eruption on April 17th. That is when I knew that it was probably going to erupt, hence my earlier community post about Ruang. Ash from the eruption has now begun falling on parts of northern Sulawesi.
You just might save a life with this !
You definitely called it!
If a larger eruption happens it could bring a cooler than normal summer in the northern hemisphere.
I saw your post this afternoon (eastern time) and appreciate your opinion and warnings.
You’re appreciated! 🫶 🇨🇦
Could the first erruption have caused fissures that caused seawater to enter the partially emtied magma chamber?
For newcomers: this channel doesn't overstate its warnings. If you're in the area please take the recommended precautions immediately. Best wishes!
838 Indonesian islanders thank you for your concern. However they were all evacuated already by the government.
Yeah, unlike some UA-cam content creators, GeologyHub tells it like it is. Pure unvarnished truth is what he gives. And for that I'm grateful.
@@JamieSteamThat island. Not the neighboring one or those in the tsunami zone.
I second this wholeheartedly
I wouldn't go that far, in terms of never overstating warnings. He can be a bit dramatic. In this case probably not, but in other cases, yes.
Even a trained professional such as this stated just 24 hrs ago this eruption was dying down. 1 day later and a larger eruption suddenly occurred with little to no warning. This is why exclusion zones are put in place even when it would appear safe.
I was surprised myself. But things can rapidly change at unpredictable natural phenomena such as volcanoes.
yeah but is that what was said and left as that or did he actually say more? "Does not appear capable of producing another powerful eruption for the short term future as the pressure was released passively" I dont know that sounds much like a claim of knowing what he now comments to of not to know and now here we are with another what? oh explosion!
Thanks for all the work you put in those videos, it's a magnificent wealth of information!
Is it me or is there a very striking similarity between Ruang and Vesuvius in terms of eruptive behavior?
This seems to be following the same trend as Vesuvius ' 1779, 1794 and 1822 eruptions....
Small scale eruption at the summit, then escalation into very large explosive events in a few hours...
About the lava dome at the summit of Ruang, I don't know the composition and viscosity of the lava but, based on the fountaining behavior it seems to be rather fluid for an andesite composition, something resembling the 1906 and 1944 Vesuvius' lava flows, which were of the scoria block type (thick aa).
@@GeologyHub I do think this is HHTH 2, and it wont stop here
@@mad_warlock666what does HHTH mean
After listening to his videos for a year, I think I can safely say, I've never heard him give out such warnings.. This says two things about him.
1. He cares about those that are affected by these dangerous situations.
2. He seems to be getting frustrated to the point that he is telling people to put cast iron pans on their heads and "yelling" at these to "get out of there".
To those of you who are affected, he is NOT joking. "get out of there"
Only thing missing is to wear a hot-pot holder with the pan !
During the April 17th eruption he said, "for the love of all that is good...get out of there!"
You can also just put your 4 lines without empty lines in between... Why force people to click "Read More..." unnecessarily?
It's basically the same effect when seeing First Responds running past you, barely stopping to say "get out." Get out of there at their speed or faster if you can.
@@rngnv4551 That's a good comparison.
I've seen that go wrong once, an ambulance worker ran through a crowd during market hours and the crowd split up between following him and getting out the way, bumping dozens of people over who had no clue what was going on.
People just presumed he was rounding people up, but he just gestured them to get out the way because he had to get to a toilet.
He made it.
Moral: The collective IQ of a crowd drops by N where N is the number of people in said crowd.
U were right about the warning!
There are very few 'pure' things left on YT, this channel is one of the few. Thanks for always keeping us updated on what those pesky rocks are up to!
Its shocking how unpredictable volcanoes still are.
Given that we cannot see or really monitor the underlying magma chambers or the lava tubes feeding said volcanoes, it is to be expected.
@@goldenhate6649 but we can at least monitor with sensors, seismographs and interpret the behavior of the volcano.
I read a book that said the bradyseism alone is a big problem. And they are uncertain when to evacuate. Its not always clear.
@@Mastercrack_GS I remember Merapi volcano, it has the most advance monitoring system and the most monitored volcano in Indonesia.
It's known for the effusive type of eruption. But in 2010, it changed its pattern, and became explosive. The phyroclastic clastic flow never reach 5km, but that night it traveled 16 km.
That night the government broadened the danger zone, but it's too late. It killed more than 300 people.
@@Mastercrack_GS You can do that before an eruption, but in this case, the volcano has already erupted for multiple days and to my knowledge has destroyed most of the sensors on the island itself. Ofc they are still monitoring it, but the closest censors are usually the most effective.
Very dark here (North Sulawesi) ,,,it's 9am.
Isn’t it supposed to be sunny for u guys rn anyway I hope it’s not bigger than it seemed
There’s talk (in this comments section) about this being a potential lead up to a Krakatoa-like event, but this seems to have more in common with the 91 eruption of Pinatubo (so far).
That said, there’s now a question as to whether the entire series of islands actually forms the caldera for a much larger single volcano. And Indonesia’s Volcano’s really are next-level terrifying - inside a century, they had the VEI 7 1815 Tambora eruption and the VEI 6 1883 Krakatoa eruption.
Agreed. Ring of Fire on steroids.
Gah your videos are perfect considering the topics. Rather than creating panic or craze, you're straightforward and honest.
I hope people there learned of your earlier post, and took action before it erupted again.
I hope the people on the adjacent island are okay. This is awful.
Geology Hub's warnings to people on the islands to be vigilant of tsunamis is highlighted by the fact that Japanese media are today reporting that te Japan Meteorological Agency are monitoring for any tsunamis caused by this eruption hitting the coastline of Japan. Japan is obviously thousands of kilometres away and if it is serious enough for Japan to be monitoring, those on the affected islands should be taking it a thousand times more seriously. Not only Japan of course, but I would imagine that other countries in the Pacific are also being vigilant. To most people here, this is preaching to the converted, but I write this message in the hope that someone looking for information comes across this video, watches it and sees comments like my own and heed the warnings.
WOW. Ruang just goes to show how the most dangerous volcanoes are the ones you don't expect, nobody would have thought that that random island would be capable of such intense activity just a year ago. I can't imagine that anyone will be living on Ruang island anytime soon after this. I'm really curious what the chance of a flank collapse, seawater intrusion, or caldera collapse is with this volcano, those slopes look very precarious and the eruption size combined with the ring of islands feels suspicious.
The government should had evacuate everyone from the danger zone. This is a small island, and seawater could play some tricks here, creating massive explosion. Hope it would not happen.
I sure hope this isn't a continued build up, ala Krakatoa 1883. These island volcanoes are the scary bunch.
I bet it’s going to have like a huge high end vei 5 eruption then it’ll shut down but I think it had a possibility for this current eruption to be a low end vei 5 eruption
Thank you Geologyhub.
Well this doesn't sound too good. I hope everyone gets to safety. Thanks for sharing and have a nice day.
Unparalleled coverage by our expert volcanologist.
Oh. My. Gosh. Sorry for the comparison, but the eruption column of 25 kilometers is now taller than "cloud 3" of the 1980 Mount St. Helens eruption, and only 5 kilometers shorter than "cloud 4" of the 1980 eruption.
To those near Ruang, STAY SAFE EVERYONE! Listen to the advice of authorities and do everything to remain safe.
And that is why I think that this eruption is a low end vei5 eruption
Wow this volcano is not predictable at all
I really appreciate your channel. Thank you!
I am surprised it erupted again, and even bigger than before. Let’s hope it doesn’t get any worse.
Thanks for posting! Thanks for your warnings!
scary that a volcano could seemingly die down and then explode violently again
ty for your updates
I'd been wondering what was happening at Ruang. I'd seen/found nothing about it, even from the third day. This wasn't what I'd expected to hear. Like in Iceland, going quiet isn't always a good thing with volcanos.
You called it right. Even if this did not occur you were right to call it as the forming plug was a clear danger.
Well done, you may have saved lives GH & there is no higher purpose than that.
Remember guys Krakatoa had at least 3 major booms each greater than the last until the whole island vaporised. Ruang is repeating history. Also to note the increased moisture vapor blown into the mesosphere (upper) was estimated at an increase of + 15% with smaller S02 amount but also launched into mesosphere by Tonga eruption of 2022 stuff we know cooled Oceania by --05 C and increased rainfall till current days. Add this stratospheric penetration with 2022 Shiveluch 71000 foot eruption and a distinct picture starts to emerge of our upper atmosphere not getting back to normal. These effects aren't going away and with our magnetospheric pole excursion impacting increased solar radiation overall well volcanic surprises will continue. History has shown us this behavior is cyclical and is a repeat of 42k and 12k years ago. But well done to GeologyHub you really are doing great work.
If Ruang will go Krakatoa's path, then I really need to cover my ears well. I remember reading an article about Krakatoa that it shattered and deafened the ears of people all the way to Australia! Hopefully it doesn't happen though, especially with the potential tsunami that may form if the entire island collapses.
Keep in mind that the Tonga eruption ended up warming the Earth instead long-term because of all the water vapor put into the atmosphere. The SO2 emissions from that eruption were actually far smaller than expected, hence why it was initially rated as only VEI 4.
Krakatoa had several months of large explosive eruptions leading up to August 27, 1883. The 4 explosions that day were far beyond any of the previous explosions. The loudest was measured at 180 decibels 100 miles away. It is estimated that right at Krakatoa, the sound was 312 decibels.
@TheWigglergler I must disagree with you firmly here. The people claiming warming were the same people that claimed 2023 was 3 or 4th hottest year in125,000 years. Paid IPCC or UN with their funding on the line. NOAA did disclose not just Oceania over the last decadel period of a --.05C drop but so to most of the other regions of the Southern Hemisphere have had reduced decadel temperatures. Interestingly I have the satellite feed showing by 29/04/22 the grey coloured cloud that had circumvented around the globe by the said date. Interesting that on 01/05/2022 all internet footage had been totally removed. Why would they do this?Even lay people know that increased blanket cloud cover reflects sunlight thereby reducing global heat. We are talking about volcanic dust and vapor being injected into our highest levels ie: 158000ft in under 30mins. When the satellite was flying over the explosion the cloud rose so fast even the lens had moisture droplets appear on it in real time. So @TheWigglergler you just want the narrative to repeat go ahead but why don't you look for yourself you will be very surprised.
Spot on. Now add in whale teachings, birds falling out of the sky and recently, a rancher reporting random electrical burns on his cattle. It's going to get real fast. Why are billionaires building rockets and underground bunkers?
Safety first! Thank you for your continuing coverage!
may all those residents nearby be safe. buildings and other similar things can be replaced, lives cannot.

Wow this is wild! Thanks for the update
This channel ......ROCKS!
seriously people ...Get out of there!!.
I see what you did there.... :)
This volcano seems to be a bit more unpredictable than others.
Doesn't help that the first eruption destroyed most of the monitoring equipment
No volcanoes are predictable...
This Ruang beast is really making me think of Vesuvius, there's a lot of similarity between the two in terms of behavior...
@@pierreetienneschneider6731both vesuvius and ruang are near the beach. If any seawater rushes into the magma chamber, we get a real powerful blast.
@@pierreetienneschneider6731 Hm, Vesuvius went for one single eruption vei 5, which opens eruptive cycle, and then continues with vei 3-4-3-4 and shuts off... This is going for vei 5 already and still increasing! For me its giving Hunga Tonga vibes, hope im wrong, i really hope so :D
Thanks for the continued updates. Greg😮.
At 2024/04/30 02:00Z that area is now in daylight. The Korean Geostationary satellite is showing a massive brown plume surrounding the island in the visual bands and in the infrared it appears that a new eruption has just occurred.
I'm in awe that a volcano can erupt so powerfully and 2 weeks later, do it again, but stronger. My heart goes out to the people affected. This is quite a crisis
Stay as safe as you can guys.
All the best from da UK 🇬🇧
👍👍🙏🙏🌋🌋🇬🇧🇬🇧
This is why i love mother nature, we can predict, take guesses, and then it shows us how it can do a 360 and blow every analytical theory out the window.
Thanks so much for what you do. You're my volcano guy for sure😊
Sounds fearsome!
What if Ruang do a Pinatubo, just like in 1991 eruption of Pinatubo, it first erupted on June 12 with a VEI 4 scale eruption and then the VEI 6 happened on June 15. But I hope it won't be the case this time.
It happens same with Tambora And Krakatoa Aslo Begins With Small Eruption Ends With Powerful Eruption
Not the right magma type for such an explosive eruption.
@@pierreetienneschneider6731 I believe the current eruption is already explosive. I could be wrong.
Thanks for the prior warning. Have family to the south in Sulawesi. Will have indonesians in my group follow you.
You are a good man, and your concern for the local population is clear and evident. We should share it and hope for the best in all this. Thank you.
A well timed risk warning given. Thanks for your dedication and honesty. I hope people are indeed heeding your advice. 👍👍👍🇬🇧
Walking around with a pan on your head might sound silly but it could save your life.

I would rather watch this channel forever than watching news forever
thanks for your work
Is it possible for a caldera forming eruption from Ruang? Keep up the great updates, GH!
Probably but let’s hope that doesn’t happen for now..
Could this cause the eruption to be ranked a low-end VEI 5 eruption since both of the Plinian eruption phases are considered as one whole eruption?
No. This current one is 0.4km³ while the earlier one was smaller. So, it's still a vei 4 even if both are considered.
@@wildlifeisthewealthofnatur5457 the first blast was .4 cubic km. This blast was larger. If the second blast is .6 cubic kilometers or larger, or the total of all ejected material since this eruption began (from before the first blast, during the dome building sequence between blasts, during this blast, and after this blast, this eruption can easily pass the 1 cubic kilometers of tephra needed to rank in at a low end VEI 5.
Plume height of this blast is already quite insane and energetic. I would not be surprised if this blast is enough on it's own. We also do not have accurate tephra calculations for either blast yet, only estimates. This latest blast has literally zero information on size other than plume height, which is... Substantial to say the least.
@@wildlifeisthewealthofnatur5457 Geology Hub said that the earlier eruption was 0.4 km³. I don't think so, but I don' know all the data.
@wildlifeisthewealthofnatur5457 The first plinian eruption was 0.40 cubic kilometers. However, the video stated that this second plinian eruption was bigger than the first one. Since both plinian eruptions are considered as one whole eruption, that means that at least 0.80 cubic kilometers or more could be ejected, rendering the question if it will pass the 1 cubic kilometer mark?
Great report, thanks so much. I hope everyone is sensible and that they keep themselves safe! ❤🙏😇
The earth is alive man! We out here
Thank you, this was a interesting record and explaining the event.
Thanks!
Thanks.
I was correct then. After the eruption on the 17th stopped abruptly, after being so violent, it sounded very similar to the description of the way Krakatoa went before the big one. Those Indonesian volcanoes put on a show.
Like fr rn This Is what i Fear That Volcano will Explode Even More Violent Than It Was Because That is Not Final eruption Yet
It never stopped, it was building said lava dome that lead too this event
imagine the entire caldera is waking up and the whole thing goes boom. are the other volcanos showing any earthquakes? idk why. but i got a feeling this Rang is is only showing us a taste of what is to come. a very small taste.. sure a super eruption is unlikely. but who knows really with sea water, and a hidden caldera, an undersea vent previosouly opening up could be a bad bad omen
Mt Awu,Mt Lokon Thoose 2 Volcano Aslo Show A Recent New Activities
Bro, you called it. Well done
Holy crap, that’s a huge lava fountain! Very scary!
The Ruang volcano is close to the equator, will it affect the climate in the future?
They were already talking about the slight effect it'd have on global temperatures from the last eruption and then this one appears to be larger.
will make it cooler like pinatuboo
1000M high lava fountain holy guacamole.
Thanks for the prior warning, have family to the south in Sulawesi. Will have Indonesians in my group follow you.
Worst case scenario like going Krakatoa, that neighboring island is doomed. If the tsunami doesn't get you the pyroclastic flows will.
While unlikely yeah if this system produces an major explosive caldera forming eruption it would be very bad indeed, especially if as suggested by the tremor after the 1st eruption that there are ring faults meaning all 3 islands are part of a single large caldera complex rim.
Man They should Evacuate Immidiately
The northern hemisphere will probably have a cooler summer than normal this year.
Haven't had a summer here in 3 years so nobig deal tbh 😂
@jjMcCartan9686 all I've had is summer (and a few weeks of winter)
I was going to guess hot but rainy.
The Eruption is pretty much right on the Equator
however the eruption is probably not gonna alter the climate, or if it does it would be minimal
The 1991 eruption of Mt Pinatubo caused a cooling of 0.5c or 0.9f, however that eruption ejected ~13 km^3 of tephra and 12 million tons of Sulfur
Ruang's eruption is still ongoing, but so far it is at least 13 times smaller than Pinatubo's 1991 eruption
@@clover5172 aw :( I wanted it to be colder (but I still would like for the people to get far away from the eruption and be safe)
Has this happened before in recent times? A volcano producing two VEI 4 eruptions one after the other like this? Could the whole event be considered a VEI 5 then if the amount of tephra is sufficient?
I would say that this whole episode is 1 long eruption, so the amount of tephra release pre-Plinian 1, during Plinian 1, between Plinian 1 and Plinian 2, and after Plinian 2 must all be taken into account.
It would still be the same eruption according to Smithsonian's Global Volcanism Program. It states an eruption is over when 90 days have passed since the last eruptive event. Considering the last eruptive event prior to this wasn't even two weeks ago, it'd therefore be one and the same. As for VEI, that'd indeed be increased if the eruption as a whole produces sufficient volumes of tephra.
With the two major events happening in two weeks, its probably a VEI5 eruption now.
@@simonlemerveilleuxdelisle3779if the first plinian phase ejected approximately 0.4 cubic kilometres of tephra, and the second plinian phase seems to be even more violent, then yeah, it can already be a low-end VEI-5
When I was looking up Icelandic volcanism the ~939 Eldgjá eruption Katla's bigger counterpart to the Laki fissure eruption from Grimsvotn apparently seems to have involved up to 16 different Plinian eruptive columns along its extent which were potentially cotemporaneous. For context this eruption was basically the consequence of Mid Ocean Ridge extension, basically what is occurring along the Reykjanes peninsula, but with the active spreading fissure happening to be the fault lineament where the Katla stratovolcano's primary magma chamber resides leading to the rapid discharge of much of Katla's siliceous magma chamber. The Laki eruption was much the same but for the Grimsvotn volcano though I don't know how extensive its explosive content was I think Katla is generally more silica rich than Grimsvotn is but don't quote me on that. These eruptions were primarily effusive in the sense that most of the material erupted was basaltic but both were highly explosive with eruption columns reaching in to the stratosphere which is why their impacts were so severe. These are tiny compared to flood basalts and notably even those appear to have had some nasty explosive content as the Siletzia terrain contains a number of samples of subaerial lapilli from the oceanic flood basalt thankfully one of these occurred in geologically recent times but I digress.
In another context I can't help but think back to the video a week or two ago on Taal's eruptive history finding there were a series of young closely spaced explosive caldera forming events a total of 4 within the last ~6000 years. This seems to suggest to me that Ruang might be one of these erratic temporally closely space explosive eruption producing volcanoes.
Volcanic lightnight is One of the few things that makes me stop snd stare like a kid
well you called that one.
I have never heard this sense of immediacy from our host here before.
If there are people in the danger area, or people who can exercise authority in the danger area, please listen to what you are hearing. Your lives factually depend upon it.
Good chance this is a high end VEI 4 or low end VEI 5. Hopefully not as strong as Hunga-Tonga's eruption.
I lived through the Mount Saint Helens eruptions and can tell people that they are in grave danger if they are close to this very active volcano! The mudflows and debris from an eruption cannot be outran. Don’t believe what movies show! You cannot outrun this! Get out of the area! Get to high ground! Go now! Don’t wait! Run, dammit, run!
Thank you for giving the facts and not fear mongering.
You called it!
NEVER underestimate a volcano. They can surprise you in a heartbeat.
Great information appreciate the safety tips !
1:24 he’s right go like Brock and wear a frying pan like a protective helmet
A timely warning - this could prove to be a globally significant event seemingly
Wow!!!
Yes stay safe
Txs
2 plinian eruptions in 2 weeks. Thats not an easy feat...
Amazing beauty
Is it possible that it might pull a Krakatoa in 1883 and erupt so violently it blows itself up?
That's extremely unlikely.
Incredible power 😳
You called it! I hope anybody listening heeded your warning despite not being "official."
What are the chances of this eruption potentially reaching a Vei 5 on the Volcanic explosivity index?
I ask as the 1st Plinian phase of the eruption possibly ejected 0.4 km^3 of tephra and that's where it was before this new and possibly larger Plinian phase
I'd say pretty good chance probably above 50%. This would be the second VEI 5 eruption in less than 3 years.
As a legit volcanophobe, you calm me that at least i can hear about it same few hours.
With the ash reaching over 82,000 feet, will it cause any regional climate disruption?
Hope the people can stay safe.
Feel like there still could be worse. It was predicted another major eruption would come but not bigger than the one two weeks ago.
You have never been wrong, and everyone should heed your warning. Please stay safe.
Seems crazy that folks are seemingly unaware of the immediate danger posed by this eruption. A combination of a plinium eruption with all that entails and the possibility of a tsunami would be enough for me to seek safer areas. Maybe an amount of ignorance of the threats and familiarity of the mountain/area has made folks Blasé to the dangers.
I think the fact it is on another island makes it appear safer, if it was connected then people would immediately run away
Yet i haven't seen local news covering this recent eruption 😭
Maybe because local medias still talk about AFC Asian Cup Indonesia vs Uzbekistan last night (I'm Indonesian. Sorry if my English is bad)
Same. Yesterday I had meteologix website open all day trying to monitor through the satellite imagery. Where's the news??
Are there any live cams there? It would be epic to witness this as it unfolds
Is the eruption a VEI 4-5?
Borderline. The first Plinian Column was .4 cubic kilometers. This one is undoubtedly bigger, but by how much is not known. You also need to add up all the smaller explosions and tephra ejected before the first big event and this one, as well as the explosions before and after the first big event.
Right now this is 2 VEI4 level blasts but that could still land in the VEI4 category. We also honestly do not know what the future will bring at this volcano. If the eruptive sequence continues and another large blast happens, it will undoubtedly breech the VEI-5 mark.
That looks so F*kn dope
This o e is going to go for a bit. Last I heard over, the radio was in part the neighboring island is being evacuated to areas that are less in danger. These eruptions are going to have a wide-ranging effect on everything from the weather to the ocean. In the coming year, there are going to be cooler temps worldwide, and this will also have effects on the crops that get planted as well as harvested. Last year in my area, the temps were up in the 80s by this time, currently the area is still in the upper 40s topping out in the mid 70s if that warm, all the volcanoes going off the way they are it is having a wide ranging effect globally on the weather as well as weather patterns.
I hope the people in this area pay attention to the warnings
Said it before, this Volcano has too many similarities with Krakatoa to not rule out a caldera forming eruption/collapse due to seawater entering the volcano (Ruang has active vents below sea level). The Tsunami risk for Ruang is very high.
Impressive. I was just checking this volcano yesterday, wondering if magma supply was slowing down to dome and if it was just gonna slowly go back to sleep...
Guess it's still got plenty of Andesite or maybe a smidgen of dacite left to enlarge island. A big few or partial collapse could join the two islands.
Really spectacular eruption and I'm confident the people there are safe.
