Major Eruption from Ruang; Tsunami Watch, Stones Fall from Sky

- The strongest volcanic eruption in more than a year just originated from the Ruang volcano, resulting in tsunami watches being posted. The volcano's lava dome exploded at approximately 7:40 pm local time, sending a plume of ash to an altitude of 21 kilometers or 69,000 feet. Two kilometer high lava fountains were subsequently generated alongside numerous pyroclastic flows, and now there is a chance that the nearby Tagulandang Island will be evacuated. Today's video discusses the ongoing eruption and the rapid escalation which occurred in the last 18 hours.

For any new viewers, GeoHub's warning about getting the hell out of the western coast is very serious and severe language coming from him. Get the hell out of there
Thanks, I am a new viewer, and I am in shock...
@@richersonkate He's never been one to exaggerate and as such it stands out when he gives such a dire warning. I've been watching this channel pretty much from the beginning, yet I can only think of a few times he's been so direct.
I’ve never heard him say that. It must be extremely dangerous.
H-sapiens Populations in islands with high # of dormant volcano?
Been following him for a while now and this has to be the most extreme warning he's issued, he's clearly very concerned, hopefully he saves some lives today.
Wow!! This is the 1st time Geology Hub has been deliberate in their warnings! Almost ~FRANTIC~!!!!!!
Local agencies have slow response and less than adequate evacuation.
Yes, he has such a calm voice, and to new views he may sound calm, but I could hear the stress in his voice. That's when you know you have to get out of the way.
this is a really dangerous situation there, a life treatening one for everyone not far enough away, this could get even worse if we have bad luck.
@@hildeschmid8400 Having been his viewer for some time, plus having certain geological knowledge- this is the most stressful I've heard him for a while, plus I had a hunch that Ruang was gonna go really bad- and it has.
Definitely a good person concerned about the safety and well-being of people in the path of this massive event.
Wow this is the harshest I've ever heard you talk about an event. Hoping those on the west side heed the call.
He is definitely not one to exaggerate and as such I can only remember a couple of times he's been so direct. But you are right, he's rarely this forthcoming with his warnings. And rightfully so.
The Boy Who Cried Wolf, comes to mind. People tend to listen when they suddenly hear such a dire warning. Especially from someone who has no history of _"doing it for the views."_ So it's a good thing that he doesn't "cry wolf" the way some other geology channels do.
@@Benson_aka_devils_advocate_88 I agree 1,000,000%
Thanks for your update. We have family living on this island, so your information is much appreciated. Locals are already leaving for higher grounds. There was a black out in the island a few hours ago. It's nighttime currently around there, so there is a bit of chaos in the island. There's many reports about the falling stones around Tagulandang.
😢
I hope your family remains safe.
Best of luck to you and your family!
May your family and these communities be safe through this chaotic situation. 💜🌏
They should probaby evacute the other island too, especially coasts
Long time viewer here and have NEVER heard him be so direct in his warning...Please heed his warning and be safe.
Prayers
2 km high lava fountains is a serious event. Thanks for the report.
3 km
And those lightnings....we anxiously monitors toba and tambora😅
Ash not lava plumes
Nvm
its actualy 3km high, and the clouds strech into an estimated hight of 22 - 28 km into the sky.
Im from Indonesia, quite surprised by the speed of volcanic activity produced by Mount Ruang. It's only been less than 24 hours since it started being raised to eruption status. As far as I know, only Mount Kelud is in East Java can increase volcanic activity very quickly. Hopefully everyone will just be safe.

People think the water will stop the pyroclastic flow it can actually travel faster less friction on the water, it’s like a supersonic steam roller
"For the love of everything good..."
Agreed! Hope they have already left because the wave should be there by now.
As the eruption continues to occur, he said there is a chance of a pyroclastic flow that reaches the sea and causes a tsunami. So it's not something that is done until all the eruption is complete.
A tsunami is far from guaranteed. It might not occur. However, I deem the risk of a tsunami occurring to be high enough that people in the relevant area should in my opinion, evacuate.
@@TrassikActually the biggest threat that he mentions is pyroclastic flows extending across the strait and up onto the coast of the T-island. And yes that is possible - pyroclastic flows from Krakatau took out a village on the shore of Sumatra.
However (I imagine) there are two even worse case scenarios. The first is a major caldera collapse - I doubt if any reasonably cautious expert could totally exclude that, though they might have good reasons to say it is unlikely (GH and the professional-level commenters - any opinions on this?). The second is if the collapse extended beyond the coastline, producing a massive explosion as seawater came into contact with magma. That would presumably only be plausible if the magma chamber extends under the sea - I have no idea whether it does, or if it is known one way or the other. If it did happen it might well be a Krakatau-scale event, with a major tsunami and climatic effects for the next couple of years..
This has to be the most impassioned plea for evacuation from a danger zone ever made on this channel.
This VEI 4 eruption is a serious threat to the immediate area.
So what, you’re just gonna downplay the severity of the volcano eruption here, how about you delete your unknowledgable comment and never return to this channel
@@curious5887 He is the type of i diot who will sit on a 100 feet tall lava dome on the verge of an eruption and say people are panicking for no reason.
What a rapid shift in events - both type & severity! A plinian eruption was not even suggested by seismic activity just 24 to 36 hours ago. This is an amazing display of volcanic power...
Yeah it is awe inspiring in every sense of the word i.e. terrifying, awful, and fascinating all at once. Given the rapid extent of escalation I suspect we are dealing with some form of convective crystal fractionalization induced by magmatic mixing/rejuvenation as these kids or events based on the analysis of crystal cores from explosive eruptions indicate that the escalation of such larger voluminous eruptions VEI 5+ tend to occur in a timescale of hours to days drawing much of their rapid energy from the sudden and rapid release of latent heat of a cascading chemical release of latent energy.
Actually, Dutch Sense was actually very sure of this and the earthquake in Japan and the one in the Philippines.
@@heatherstub No doubt. Dutchsinse is almost always ahead of things. Unfortunately YT algorithm makes it difficult to get his updated postings - even when subscribed.
Evacuation alert was issued since last night around 5-7 hours ago for the island surrounding the volcano. While I'm living on another island far away. As per some info from the locals, the majority of people in the west coast have been self-evacuating since the tsunami watch issued (still unconfirmed by the government but highly likely). The disaster mitigation agency is currently deployed in the region to oversee the remaining evacuation and monitor the situation up close.
It's good to hear that there's an agency there to help people in this crisis.
Yesterday you felt a pyroclastic flow was unlikely unless as you stated a lava dome grew... and that happened.
You nailed it.
As a VEI eruption as strong as this is rare anywhere you logically made it a low event possibility but did say it could happen.
Well done GH.
Wow. I haven't heard you get this blunt before. Hopefully these people have all gotten to safer places.
Thank you for the update. This sounds like one of the more dangerous eruptions of the last few years.
Thanks for keeping us abreast of these developments. Prayers to all living things in the area🙏
Beings not things
Hearing that a submarine vent appeared sounds concerning
How great of you to warn people here on this channel too, instead of just give analytical reports
(which I would consider "normal" as you are not the authority there! So it is extraordinary good of you to do that out of your own humane perspective)!
I hope your channel is watched by people there and taken seriously! 🙏🙏🙏
Take care and be safe Indonesia. Move away from the coast. YES! 100 meters above sea level! KiaOra from New Zealand.
Thanks. This is the 6th dormant volcanoes erupted in this year. The Ruang volcano has been dormant for 22 years! We anxiously monitoring toba and tambora😅
Thank you
@@nurlindafsihotang49 The Ruang Volcano has never been dormant. Volcanoes are ACTIVE if they have erupted any time in the last 10000 years, have active geothermal features, or have a documented active magma chamber.
2:27 Do not use the butter, though.
Noted. I used coconut oil
Be heart healthy and skip the butter. Use olive oil instead.
@@drury2d8Lard is the way to go.
@@CreativeWarrior- I have lard I'm saved!!!
unless you're French... then there is never enough butter.
This channel has always taken people's safety seriously. If he says there's imminent danger, there is!
Wow!!! This took 6 months from just a slight increase in seismic activity to a plinian eruption . The videos are breathtaking. Thanks for the very important update.
I blame Pliny the Younger myself, he started it...
@user-lh5fp7bf2c - I have never heard of Pliny being used as an adjective. Seems apt.
@@wildliferox2 - I thought it was Pliny the Elder that died during the eruption and Pliny the Younger wrote about it.
@@MossyMozart Indeed, RIP to the Elder.
Good for you for the warnings. This is a BIG eruption and who knows how bad it may get. Remember Krakatoa! Watching it from so close is insane.
Also WEAR MASKS to filter out ash, as that is very hard on lungs!!
Thanks. Your report is so thorough and timely. ❤❤
Thanks for all of your hard work man!
Wow, there's a lot going on in this video. Crazy that people aren't aware of the obvious dangers .
TikTokkers are to blame. I bet you at least a dozen are standing there right now, building up muscles by holding their phone(s) up to not miss a second of their final seconds.
Not a synapse in their brains is busy correlating danger to imminent threat, too high on dopamine and livechat engagement.
Darwin Awards being readied.
@@Yezpahr You can't place blame on tiktok people alone. There's a thing called common sense that has been absent from people's mind for long, long time.
Natural selection is observing this silly behaviour with dismay. Fascination is one thing, but ignorant stupidity is a bottomless well who's depths some people are eager to plumb.
Reading the first two comments and I can tell both of you guys had no idea living on the nearest volcano, especially when the volcano had not erupted for like 2 decades and it blows suddenly. Agreed with Glaceon42, some people just did not know that it was going to go like what happened now.
Information, plus a kindly warning for dumbbells.
..i *like* this channel!!!
Can we all be thankful that the government had the foresight to evacuate all 800+ residents from Ruang earlier in the week. So hopefully nobody has died yet. But those on the neighboring island need to get the hell out of there.
Indonesian volcanologists are some of the world's best.
Wow, this is incredible. I am hoping that folks over in that part of Indonesia are taking notes and getting to high elevation. This volcano should not be taken lightly
I couldn't believe it when he said people were watching & recording the eruption from that close i know its another island but really, i hope they see sense and heed his warning and move to safely. And as always thankyou for this volcano update
Thank you for your prudent warning to those who are foolish enough to stand too close. They need to all MOVE NOW! 🙏😇
Many people don't know that pyroclastic flows can travel across water.
The warning is warranted. Thanks for the update.
Fantastic breakdown on this event, well done!
Over mile high lava fountain it's time to run 😮😮
After following this channel for years and hearing the most level headed explanations against fearful misinformation, there is no doubt in my mind that these people need to get out of there ASAP.
You'd never lead on an audience like that. That being said, as soon as I saw news of the eruption I knew where to go for the most informative video on the situation and you never disappoint. Thank you for your dedication and thoroughness. 🖤
Thank you for sharing! 😊
Also if you are in a region of falling ash wear cover you mouth and nose with a cloth or dust mask or something that will block the fine ash because the ash can cause all sorts of respiratory issues. Plus it's literally small fragments of glass that's in the ash
Hard to put it more plainly than this.
Instagrammers, GET OUT.
Thanks and I enjoy your science based updates.
Thank you for the update.
Thank you for the update. 🙏
Two massive eruptions on 3 years in the same general area.... this could be a global weather changer.
Ikr? Iirc one of the reasons we had a wet El Niño even in Australia was the Hunga Tonga eruption
awesome video, thanks!
This volcano isn't like the ones in Iceland. In Indonesia they have a bad habit of going BOOM!
Part of me wishes he wasn't nice to the people observing the eruption from the western shore.
"Get the F**k out of there you blithering idiots!!!!"
Soon to be blistering idiots.
Tbh I do agree with u but I have seen comments on the other video sayings that they think a vei 5+ could be possible which I agree a vei 5 might actually be possible which is absurd honestly it’s crazy
I understand but it would not be professional to use such language, this isn't some teen gaming channel. Also it is mostly "look at me I use bad words I am so cool" on TH-cam. Which in itself is very cliche.
Im from tagulandang that is very accurate
Thanks for the continued updates and keep up the good work. Greg in Southern Ontario Canada. 😊
Geez that's a sizeable eruption at 21km height of the column. May end up the biggest of the year.
Wow, what an eruption !
Thanks!
thanks for the report and warnings
pay attention people
Wow! I heard it from you first. I’m glad I follow you. I hope everyone stays safe.❤
I could go for a "year without a summer". Sambora had a major eruption like this till 5 days later it went big bada boom (VEI 6).
Do you mean Tanbora that erupted in 1815? That was actually a VEI 7 primarily because of the massive discharge of tephra. Upwards of 37 km³ or 9 mi³.
I am in the UK, we already had a year without summer last year. I can't do another one. Also I'd prefer if the people there are safe and don't get blown to pieces. It's bad enough as it is.
Thank you, for sharing ...😭🙏🙏🙏
Could you provide a source for the 6:00 PM submarine vent eruption report, couldn't really find it anywhere
where do you get the videos of the ruang eruption?
im an Indonesian yet the eruption is barely being noticed in the news because the island is quite remote :)
its all over the news.
dengan kekuatan ponsel dan internet bu banyak sekali gambar dan video yg muncul
nggak heran ada yg memprediksi bakalan tsunami
byk komen juga yg menyalahkan kok nggak pada pergi malah ambil foto dan gambar
alhasil dikira indonesia sedang kena bencana
padahal bisa jadi abu vulkanik gunung ruang nyasar ke malayia atau philipina
tetap saja dikira seluruh indonesia sedang kena musibah
bisa jadi sdh ada negara kasih travel warning jika mau ke indonesia
cmiiw
To my volcanic brother the creator of this channel thank you so much you're one of my favorite channels I watch you daily and learn so much and these large and unfortunate events are some of the main reasons why I watch just to be informed and you do such a good job thank you my volcanic breath brother
I have a friend in Manado, I hope the people pay attention and stay safe.
I hope you might have time for an update this evening...
Thanks for your warning, let's pray that people listen 🙏
I knew it'd be VEI 4. Keep safe everyone near the volcano.
Is there any chance of this eruption becoming VEI 5?
I think there is a low chance but what this volcano has done so far I wouldn’t be surprised last video he said it might get to a vei 3 now it’s a vei4 crazy
any live cams on it?
Wow - do we know the S02 content of the ash plumes? 2km sustained should be enough to get that stuff into the upper atmosphere and affect weather next year if it keeps happening. What are the chances that we can see a situation like with Tonga's volcanic eruption, which you'd hope would be a once-a-century event. I saw some of the rescue footage and thought that was so dangerously close, but they were trying to help people.
I was thinking the same thing. That's a high plume! Hopefully the government is helping people get out of harms way.
They were slow than expected evacuation. Both island should be evacuated
The Tonga eruption was a very rare event so this is unlikely to progress to that level.
You warned about this possibility a day ago.
He said it might be a vei 3 at most not vei4 never thought I would have to say this but he was very wrong this time
@@justinwilson3922nature is unpredictable sometime.
@@justinwilson3922 - I thought he gave it as a possibility. If so, he did get it right.
Are we looking at a possible Krakatoa?
Probably not. The eruption, as large it is, is too small to produce a VEI 6
@@GeologyHub but one can never really know....sometimes a volcano is just a volcano, but sometimes it is something much more dangerous but unless it has shown that danger previously how could you ever know if it holds that potential if it is one of those types of gassy thick magma anyway. That it had an undersea vent blow out a bit when it got plugged makes me wonder if it has unknown potential.
@@matthewbooth9265 As far as I know, the eruption of Krakatoa became so powerful and deadly because viscous magma mixed with more liquid magma, which caused the appearance of a very dangerous cocktail
@@arrionelton IIRC there's also talk of seawater intrusion into the magma chamber, not unlike the much more recent Hunga Tonga eruption. It definitely seems like that is a possibility here too, albeit a very low likelihood.
A low VEI5 is not out of the question at all, but anything resembling Hunga Tonga or Krakatau is.
Thank you for your expertise. People heed the warning. Escape when you can. Be well and I will pray.
This eruption has escalated, **rapidly**! With a 21 kilometer tall eruption column (Among the taller ones over the past year) and 3 KILOMETER tall lava fountains, to everyone in the immediate area, listen to the advice of authorities, make superb use of common sense and above all, STAY SAFE!
About spot in the ocean where the first bit of eruption occurred; likely where a new island forms?
I am praying for safety of all, wi5h love from the usa
Holy hell... I've never seen a 2Km high lava fountain!
Etna has done 5000 feet (about 1.5 km) but I have not heard of larger. Who has the video?
Watching pyroclastic flows from close at hand great idea; that is if you can travel at more than 200mph and you maintain a clear and unobstructed exit route at all times.
Nice subtle use of very grainy Mt. St. Helens eruption video, and volcanic fragments from 1944. Good of you to give credit for the visual elements that would otherwise just be a podcast.
Residents should be doing their videoing/watching from a location ≥100m above sea level
The people watching from the neighboring island are so close, if it goes to VEI 6, the reaction would be almost instantaneous.
You can litteraly see the eruption plume through the satellite. Unreal 😨
Good warning. Actually it can get far worse. The pressure buildup of gases etc might cause a catastrophic collapse of the caldera above the magma chamber, allowing billions of tons of seawater to rush into a hot void full of magma, then causing a colossal steam or phreatic eruption of enormous power; something like Krakatoa. As well as destrying the volcanic island in mere minutes, it can set of an enormous Tsunami. Worse than one produced by a large pyroclastic flow.I would leave all these islands, immediately.
This is no time for complacency on nearby islands, lives are at risk
I'm so sorry 😢 I do hope this all stops soon ❤
Wow, this is a wild one. It sounds like if any larger plug happens it could go full Krakatoa mode.
Someone called me a tin foil hat conspiracy theorist yesterday for saying that this volcano could pop, just revisit Krakatoa.....
I did not see Hunga Tonga on your VEI comparison chart (i might have missed it too)
Thank you, and I hope all affected will heed this warning. This plea from a knowledgeable, deliberate, and always calm professional should be taken seriously!
protip - buttering your head will not protect you against volcanic ejecta.
😂
69, 000 feet! Wow! 50 meter gap!
It's been 5 hours since this video was posted. Any updates possible?
I'm on the edge of my seat.
I thought they evacuated yesterday. Or was that a different volcano?
love the butter added to the pan.
I've got a pan, but I'm really gonna need that butter, homey!
If Geohub is using language like that, I would listen!
This seems like this particular eruption will cool the planet some
Probably not significantly, and not for more than a year, if that.
It does not appear to be that big.
Спасибо!
This excentric eruption 4 km of at sea is super bad news.
I hope its not a diametrically opposed vent on the ridge of a caldera....
If the hole amount of magma break out means the Vulkan collapse and see water gets into the chamber.
The rusult will be apocalyptic devastating...
Any pan recommendations for head protection?
Metal bowl maybe?
All-Clad is very sturdy. A metal bowl will dent easily. You could view my collection, if you wish.
[But a bowl is better than no protection!]
Cast iron Dutch oven😆
@@antlerking69 I have one of those! Great for making pot roasts.
This wild pray for no tsunami. Crazy eruption in general literally out of nowhere
You mentioned many people might die if they don't use common sense. The problem is that common sense is becoming uncommon. Keep up the great work on the awesome channel.
My prayers for the people there, please take these warnings seriously
I sure hope these people have somewhere safe to go.
When you're going to use a pan to protect yourself, don't forget to apply a generous layer of butter or margarine.
