So yes, Lewotobi has produced two major eruptions in the timespan of a week. Today’s eruption was a bit larger but in a different way with less lava bombs but more tephra than the Nov 3-4 eruption. Also, I do not mean by “blew its top” that it produced a lateral eruption like seen in the 20th century at bezymianny, Lamington, or Mount Saint Helens. Rather that part of the top of the mountain blew up and is no longer there.
If a volcano erupts with three eruptions of this size in a row, do you still count it as a VEI3 eruption or do you classify it as VEI4 because of the combined erupted material?
Do you know if any material managed to get into the stratosphere? I know you said the plume height was about 16km but I'm not sure of the boundary of the tropopause and stratosphere that close to the equator. Many thanks.
Thank You. By the way, I come from the island of Flores, East Nusa Tenggara, Indonesia. The eruption of Mount Lewotobi Laki-Laki also caused a kind of chain reaction which was followed by the eruption of several active volcanoes in Indonesia, namely Mount Ibu in Halmahera, Maluku Province, Mount Iya in Ende Regency, Central Flores, Mount Semeru on Java Island and Mount Marapi in West Sumatera.
No relation between all of those volcanoes. Mt. Iya in Ende has experienced occasional magma intrusion, even before Lewotobi started erupting in December last year. Mt. Ibu has erupted for 15 years straight, so clearly no chain reaction from Mt. Lewotobi. So do Semeru (continuous since 1994) and Marapi (since December 3, 2023). All of these volcanic activities around Indonesia don't correlate to each other since each volcano is fed by different magma chambers. You may just realize that the other volcanoes are erupting too because they're getting more attention after Lewotobi's deadly eruption commonly covered by national mass media.
@@AlkautsarPAThank you for your explanation. Sorry if the layman's view is like that. Indonesia is indeed on the ring of fire, so layman like me are often trapped in simple thoughts like that. 🙏
Lewotobi has produced two eruptions today. The second one in the last several hours was the most powerful the first one occurred during the day. The second one occurred at night.
One of the reasons I love Geology so much, stuff goes off very randomly at least the VEI 3+ eruptions and 7.0 mag EQs too. Really puts nature in a very clear perspective. We actually know what we really don't know.
My daughter just landed in Bali from Australia and I told her the other day you will get stuck there because of volcanoes she laughed at me know who’s laughing darling
look at the satellite imagery, another bigger eruption may have occurred today after the first one, but i can't find videos neither images taken from the ground.
Indeed, there was another big explosion after midnight, but not bigger than yesterday's. Today's explosion's ash column was around 5.8 km high based on the satellite data and was accompanied by a 4 km long PDC to the north - northeast as per PVMBG.
I would imagine that as a volcanologist a trip to Indonesia would be absolutely fascinating to you! Then after your studies you could take a couple of days off in a tropical paradise like Bali!
Is there any correlation between Lewotobi's eruption and five other eruptions that happened all over Indonesia in the last two days? I'm talking about Mount Marapi (West Sumatra), Merapi (Central Java), Semeru (East Java), Dukono (North Maluku), and Mount Ibu (Halmahera). Big distances among them, but erupted almost at the same time
That's a very hard question to answer. The ring of fire is constantly active and sometimes the activities are in clusters around the rim and other times not. Id be willing to bet that anyone who is capable of genuinely calling the next eruption would be very highly regarded and a wealthy plus probably in receipt of a novel prize
@@scrappydoo7887 exactly. I can't recall if something like this ever happened before, especially since the eruptions of those other mountains happened in the span of three-four hours (between 9-12:30 am WIB)
Marapi, Merapi, Semeru, Dukono and Ibu were all already erupting for years by the time Lewotobi erupted. The latter 3 have erupted continuously since I starts seriously following volcanoes (in 2017)
I drove past New Zealand's supervolcano yesterday (Lake Taupo is the crater). According to the research, it's the site of "the world's most recent supereruption, and largest phreatomagmatic eruption characterised to date". With all these eruptions occurring across the globe, I was pleased to find it at Level 0 (ie. no unrest), but the one close to where I live is sitting on Level 2 (moderate to heightened). We shall stay vigilant!
I'm curious about the pyroclastic flows - since we saw some happen just a few days ago but now more extensive ones flow over those today...is it difficult to measure/detect evidence from historical events where several eruptions may have occurred in rapid succession? I.e., when there are successive PFs over a short time frame do the later ones "erase" or degrade evidence of the earlier ones, making it likely that the PF danger levels of some volcanoes might be underestimated?
Correct me if I'm wrong but, didn't GH just recently predict this event? Great channel, and very important for people in harms way. Well done, GH. Cheers.
The chart of magnitude is very helpful, thank you. I expected to see Taupo, New Zealand (where the lake now sits) on there, is it an unknown because of it's age?
I need a playlist of documentary type hysterical volcanos and everything to listen to you when falling sleep/driving. My neuro-spicy brain loves your tone and presentation style so soothing (in a non creepy way) 😂
If you ever want to expand on pyroclastic flows, what happens around them when they stop isn't clear. Are they igniting fires beyond their limits? Are downhill areas suffocated by the gas it contained? Does the hot cloud deplete oxygen past it's boundaries? When can I stop running away from it, when it stops or when it cools?
how hot is the top of those plumes? if i was a bird and could fly at55,000 feet would i get cooked?if not how low would be safe? is it like a pyroclastic flow just upwards? or not?
The way the graphic shows the plug further down in conduit with the gases accumulating below makes it look like a vertical shotgun with the plug being the "shell". The gases build up behind the shell until it is expelled through the barrel.
VEI 3 eruption like this is the highest Lewotobi ever erupted. While it needs further studies, there is no evidence that this volcano is capable of producing a caldera forming eruption.
I was about to ask the same question. And the fact that Lewotobi has never previously had a caldera collapse is no reason why it can't - caldera collapses are very rare events in the life of a volcano. For instance I am pretty certain that Mount Pinatubo had never had a caldera collapse before the 1991 eruption.
@davidcranstone9044 The GVP lists 3 other VEI 6 eruptions for Pinatubo before 1991. Mid end VEI 5 is approximately the bare minimum for an eruption to cause a caldera collapse, and Lewotobi has only done 3s at most, not even a 4. Current science works in terms of precedents. If this is the most powerful Lewotobi has ever done, then it's very unlikely to collapse into a caldera. You'll need an eruption at least 100x more powerful to reach the threshold.
I think it need comprehensive survey of its magma chamber below the volcano so we can get idea from where magma suply was. East west nusa islands mostly form by volcanic and tectonic activity.
Can you say anything about the possible worldwide effects of these recent eruptions? (e.g., air pollution, red sunsets, changes in global temperature, etc.) Thanks! :)
Everything in Stralia that is wrong is King 👑 Charles third of his name's falt. Like this volcano 🌋 is on the secret King 👑 Charles Fault, lol 😂. No such thing as the King 👑 Charles Fault.

What rating would you give it if you combine both of the eruptions?
If a volcano erupts with three eruptions of this size in a row, do you still count it as a VEI3 eruption or do you classify it as VEI4 because of the combined erupted material?
@@Leyrann it's determined by explosivity so I assume they would have separate ratings
Today's eruptions did happen 2 times in a row and i presume each was VEI 3 in the minimum.

Hi, Thanks for keeping an eye on these for me (us). It's so interesting and scary and something you have no control over. Peace
Thank you for the update.
Thanks as always, Geology Hub,
Appreciate the updates. Thank you
My daughter just landed in Bali from Australia and I told her the other day you will get stuck there because of volcanoes she laughed at me know who’s laughing darling
That volcano went from 5% to 110% in less than a couple weeks.
We are so small.
Great video ❤thanks
❤ your videos!
Thank you, keep working.

Where can I see that data? I can't seem to find a good website
@ariblue400 you could search for the app Windy, the Page Meteored, and Himawari-8, etc.

A lot more explosive volcanic eruptions lately and it will continue to become more frequent just sit back and watch.

MSM ignores.....
The plume is quite visible on the Korean GEO-KOMSAT visible channel data. (2024-11-07 23:30 UTC)
There must be drone monitoring to see the current condition of the crater
There is. PVMBG regularly fly a drone to around the crater, almost every day.
Is this eruption iniecting aerosol to stratosphere?
Most erupting volcanoes do eject greenhouse gases into the atmosphere.
😎👍
Men heart will fearing them for fear to see what coming upon the face of the earth 🌎
Any word on how much SO2 is being released? And possible climate effects?
This is a couple of orders of magnitude too small for that still.
vei 3 is relatively small.
Day 1000 of taking a sip of drink everytime pyroclastic flows is mentioned.
How's the liver?
Pyroclastic flow is a pretty basic factor...
At least we drink in similar style
Non alcoholic beverages.
Shiveluch also produced a strong eruption
THIRD!
🥉

It's pretty small to have any noticeable temperature effects.

Has this volcano dormant before blow
It was erupting for 10 months before
It is a type A volcano by Indonesian authority, means it has recent records on activity.
more co2 than humans since they picked up the first burning stick ?
No, an infinitessimal proportion.
all that pollution in the air, oh humans are not in charge at all, while all the green crap goes on..to funny
