Mauna Loa Eruption Update; Basalt Lava Advances, Alert Level Lowered

[@jasonreed7522]

Thank you for including the sound of the lava flow, that was really cool. (I live very far from volcanoes and likely would have never heard it myself or realized they made a sound worthy of looking up)

[@terriellis3697]

Yes! The sound of lava- I never thought about it. So cool!

[@skateboardingjesus4006]

It's a beautiful crisp clinking sound, like heaps of brittle ceramic pieces tumbling over each other. Volcanic vitrified vibes.

[@eclipse369.]

No thanks for 2 sec clip

[@jonathanleonard1152]

That sound is specific to the type of eruption and composition.

[@skateboardingjesus4006]

@@jonathanleonard1152 Yeah, a'a flows are pretty distinctive.

[@theredrover3217]

Again good distillation of available information about the current Mauna Loa eruption. And Kudos once again for not feeding the hype mongers 👍 and a comprehensive description. 👏

I was up on the summit of Mauna Kea doing some astronomy, and could barely recognize the constellations because we could see so many stars that are too faint to see even on a very dark night out in the desert or at sea. I got a bit disoriented from staring at stars and took a hard fall into the aa. If I hadn't been wearing a carhart jacket, Jean's, boots, and gloves, I'd have gotten shredded, which I know because the clothes did! Even long cooled, it tinkles just like glass does, actually it makes more noise but it's very similar. I've only seen very fluid lava molten, and not far away, it was pouring in a fat stream into the water on the south shore below Kiluaea. I don't think it made any noise we could hear from several hundred yards away, but once it hit the water there were hisses, booms, thuds, and a sound kind of like continual thunder far off. The two most spectacular places I've seen are Hawaii and the PNW. I couldn't call them best or most beautiful objectively but they were to my eyes.

[@ksbrook1430]

I also appreciated the sound of the lava flow. I've watched a few of your episodes now, and will be subscribing. Thank you for your work.

Not sure why, but the fact that A'a lava sounds like breaking glass is as oddly satisfying as it is perfectly logical. 👌 Thanks for these fascinating updates!

[@juanitapandya6018]

The Usgs said that the Lava effusion rate was still 140 Cubic Meters/Second as of yesterday and that the eruption has stabilized as it has stayed at that rate for a few days. This was a response to a comment about if the eruption rate was decreasing in correspondence to the decreasing so2 emissions. The lava being effused is probably less so2 rich than that of the beginning I think. Just a heads up because in a previous vid you said the rate of effusion was decreasing.

[@psilocybe420ish]

Awesome content as always I do love your Channel but I have a question can you do a video about the July 10th 1996 Glacier Point landslide in Yosemite National Park that caused a sonic boom and sent over 162,000 tons of rock to thunder down into the Yosemite Valley destroying the forest below.

[@Aztesticals]

Is there any historic precedent for a hawiian eruption increasing in intensity again after this kind of slow down. Or are we most likely already on the downward slope.

[@susanl7514]

So many sounds, this one beautiful. Yesterday while watching Semeru live and fumbling with Google Translate to read some of the chat, I noticed someone telling his colleagues not to wear their headphones. Why? Can you explain this? At the time, a continuous signal of 25mm amplitude (?) occurred, so was it something to do with ongoing exposure to a particular frequency? Or is it a concern for how loud an explosive eruption could be if one occurs? I often have wondered how many decibels could transmit over the internet.

[@fleetskipper1810]

That is a very interesting question.

[@wiredforstereo]

One of the neat things I've noticed just today is that the lava flow generates its own cloud and sometimes fog.

[@Maiant]

It's not fog, it's "vog". Volcanic gasses. Mostly SO2 (Sulphur dioxide) but with a little ash, and some other things like pele's hair.

[@wiredforstereo]

@@Maiant I'm talking about fog. Thanks.

[@Maiant]

That's my point. The cloud and what appears to be fog, is Vog. Fog is kinda rare here. Clouds drop down to around the 6000ft level, which can look "foggy". But actual fog, the Tradewinds make sure that doesn't happen.

[@wiredforstereo]

@Maiant Okay, then I'm talking about clouds. In the rest of the world, when you're in it, there's no difference. It isn't cold enough where you live to have fog. It is cold enough up on the saddle. Now if you could restrain yourself from fucking correcting me, I sure would fucking appreciate it.

[@Maiant]

Except... the flow doesn't make ANY of that form. The flows, the heat from the flows, cooks the fog and clouds away. The flows don't generate any water vapor based anything. They create sulphuric acid based vapor, ie Vog. But hey, come drive through some lava generated fog. Breathe it in deeply! Then you'll learn the difference between the two.

[@sixthsenseamelia4695]

Have a look at Aoba in Vanuatu. It's looking mighty hot on the satellite images.

[@TheJohtunnBandit]

0:59 this is a lot when you have a brisk wind over a melting lake in spring, big piles of ice shards piling in drifts on shore and making a beautiful chiming noise

[@tyronewalker5764]

Nature will have its way.

[@Omti9]

Can you please make a video about why some erruptions of (shield) volcanoes produce cinder cones that never errupt again, while others errupt again and again?

[@fleetskipper1810]

From what I have learned informally, cinder cones become extinct when the part of the geosphere they originate in migrates, taking the hotspots from which subterranean magma chambers exist with them. That’s why there is a string of Hawaiian islands. At one time, the hotspots formed volcanoes that we see today as nonerruptive islands. But the hotspots themselves have simply moved to the east. There is currently a new hotspot, which is actively erupting and forming a seamount off the eastern shore of Kilauea. It will take many millennia for this hotspot to break, sea level become visible as a mountain, of course.

[@GeologyHub]

Although this may not be the answer you are looking for, the difference between cinder cones and spatter cones is how explosive a specific eruption is. Cinder cones generally have gas rich lava/magma, which as a result creates mildly explosive eruptions which eject ash. I may fully answer your question in tomorrow's video.

[@Maiant]

In the case of Pu'u'o'o, once lava drained from it (to move down into the east rift zone) it collapsed. That collapse, will most likely mean that the path of least resistance will find a new path to erupt from. I was repairing my friends roof when it happened. Huge earthquake, followed by a big pink cloud of ash and cinder.

The lava sound...to me sounds more like a shale than glass :)

[@bucketofchickentacos9625]

Thank god you talked over the sound of the volcano :/

[@paulfarrant108]

Are you able to provide an update on the recent activity on Stromboli?

[@Kevin-xi6ts]

Mmmmmmmm Stromboli!

[@AtarahDerek]

And a whole lotta commuters just heaved a sigh or relief. No one was looking forward to a three hour detour.

[@thePronto]

I'd be interested to know how Mauna Loa is erupting now after it had presumably passed over the 'hotspot' that is now feeding Kilauea.

[@Maiant]

The underground "plumbing" is still connected to the hotspot. As is Kilauea and Lo'ihi. Hualalai might finally be disconnected but maybe not.

[@xaviersavedra711]

You should make an update video about Stromboli.

[@elric_310]

Do you still plan on going to Hawaii to see the eruption?

[@feelinghealingfrequences7179]

what about the vog? what gasses and particles are going over peoples homes?

[@dolphincliffs8864]

[@danc9866]

What’s going on with Stromboli?

[@danielduncan6806]

How do you feel about volcano tourism?

[@raydenn6027]

As it' sounds so fragile.

[@harrykoppers209]

So is this eruption having any effect on Kilauea's eruption?

[@Maiant]

Per USGS, no. The two do not appear to be connected. Which seems strange, as they're so close together. But they inflate and deflate completely separately.

[@VeteranVandal]

That lava sounds like bbq coal tbh.

[@phprofYT]

More lava.

[@tymonkalbarczyk1456]

Isn't Pele's Hair cousing some breathing problems and long term diseases like silicosis?

[@DawnDavidson]

Yes, I’d be concerned about health effects. Not sure if Peel’s hair occurs in pieces small enough to be inhaled? But it seems like it would be dangerous to touch, for sure. And given all the ash, I would wonder, like you have here, whether there might be some tiny glass shards as well. I hope the people nearby are masked!

[@Maiant]

Yes. Pele's hair can be small enough to be inhaled. And travels quite far from the eruptions. I haven't heard of any silicosis issues though. I'm sure it's possible. But from my understanding, the sulphuric acid that also travels with Pele's hair, does significantly more damage. Not leaving time for silicosis to occur. And yes, we wear masks if the vog is around us for any length of time. The gasses, and particulates cause discomfort even at "low" levels.

[@tymonkalbarczyk1456]

@@Maiant Thanks, interesting.

[@lanerailvideo5928]

A reduction boo boo

[@cyankirkpatrick5194]

A few years ago, I heard that Hawaii would be underwater not by global warming 🤦🏻‍♀️🤬💔 but by sinking, but I see now that might not be the case.

[@Dragrath1]

Given enough time (tens of millions of years) it will be underwater but that will be more due to erosion and landslides rather than just subsidence. That said there is a reason why someone might make the assumption that it might sink entirely as the immense weight of Mona Loa has caused the original seafloor below it to sag into the Mantle by over 8 kilometers. Yes *Kilometers* however given the towering height of Mona Loa the tallest and heaviest mountain from base to height on Earth this sag into the mantle is relatively negligible in comparison. The same isn't true for some of the older islands however where volcanism has stopped and mantle sag is still ongoing as the mass of volcanic rock cools away from the buoyant uplift from the plume and gradually settles towards an equilibrium state.

[@cyankirkpatrick5194]

@@Dragrath1 That's very interesting and thanks.
