This Week in Volcano News; U.S. Volcano's Alert Level Raised, New Tallest Peak at Etna
HTML-код
- Опубликовано: 22 июл 2024
- This week, a significant eruption occurred at Italy's Mount Etna volcano, producing 2,000 foot high lava fountains. Meanwhile, in the United States, the alert level was raised at the Cleveland volcano. And, at Mount Spurr in Alaska, a crater lake formed at its summit despite the presence of below freezing air temperatures. This video will discuss these stories and list the 47 volcanoes which are currently erupting around the planet.

The football field graphic is a great visual to enable people to relate to the size of the lake! Thank you for all of the information you provide!
I was at Mount Etna on Easter of 1998. A few weeks before it's eruption. It's a beautiful area.
I find volcanos interesting. The fact that they can cause extinction level events and global cooling make them very dangerous, but their effects are also so beautiful.
Got to say I love those beautiful Fountains of Etna as my favorite right before Kawah Ijen's Blue Fire. Nature is so wondrous.
it's really amazing how many volcanoes are erupting all the time-and you don't realize. Amazing planet, our little Earth.
Can you do a video about the recent earthquakes west of Vancouver Island?
It looks like Etna is ready to put on another show tonight.
Can you do more videos on rocks and minerals? They’re also interesting!
Thanks for all the hard work on these videos!
Need a vid on the Charleston, SC faults and the massive earthquakes in the 19th certainly
I live in charleston its crazy that you can see some of the old cracks/repairs on some older building from that massive quake
Do you mean the 19th century?
I’ve requested him to do a video on the Meers fault in Oklahoma
We need to raise awareness of these dangerous Intraplate faults
I agree!
@@lemmdus2119 These faults are too dangerous to be ignored especially because a lot of them are near big cities and can be felt for hundreds or even thousands of miles from the epicenter and a lot of buildings aren’t built to withstand earthquakes in intraplate regions
Alaska is huge. Absolutely huge.
That's why Russia sold it to the USA!
Italy gets there own firework show
Etna putting on a Strombolian eruption. Stromboli putting on a volcanian eruption. Vulcano putting out a plinian eruption…
Where does it all end?
Vesuvius putting out an Icelandic eruption
Vesuvius putting on a Phlegraean eruption?
In a burning Ring of Fire. (I read this comment as ‘Ring of Fire’ by Johnny Cash started playing. 😂)
thanks for the update
Thank you, Tom!❤
This is a really cool channel.
Actually it's Tim not Tom, but you've got the rest right.
@@davidcranstone9044 Thanks-I only get to watch at bedtime-so...I stand corrected!
Thanks.
just a fyi Kenai is pronounced Keen eye. Emphasis on Keen. I don't want Alaskans laughing at you. I love your videos.
I heard that, too. I'm glad you mentioned the pronunciation.
Video idea: Geologist react to popular volcano scenes in movies
I second this! Some titles to consider:
- _Journey to the Center of the Earth_ (1959)
- _Dante's Peak_ (1997)
- _Volcano_ (1997)
- _Volcano: Fire on the Mountain_ (1997) [🧀🧀🧀]

My friend, when you're talking about a number of individual things which has decreased, you should use the word "fewer". If you're talking about a quantity which has decreased, then you use the word "less". I know this is a grammar nit to pick, but your videos are so informative and interesting that I want to help make them even better.
Can you talk about the Volcanos in Saudi Arabia? I think one erupted during the 1980s. Thank You!
You Should Make a video of Tamu Massif one of my favorite Volcanos its really cool
Thanks so much for your regular excellent reports. I would appreciate your commentary on current global activity and how this compares to previous years and decades?
Is earthquake activity increasing generally and by how much? Many thanks 🙏
Thanks as always! Thanks for giving us information about how Mount Spurr's crater lake may be liquid while still being below-freezing.
These Volcanoes are worrying 😊
Volcanos never worry.
Would like to see something on volcanism in Wyoming other than Yellowstone, such as the ancient Absaroka and Rattlesnake Hills.
I am surprised to not see any Hawaii or Iceland volcanoes on the list of erupting volcanoes.
Currently napping, building energy. Tune in again in a few days. ^_^
@MossyMozart
Lol, “Welcome to our island. If you don’t like the geology, wait a day.”
KEE-nai.
TIL ice cauldron is a technical term as well as a Magic the Gathering card.
Clickbaiters are missing out on the chance to title videos "Cleveland might explode according to experts!"
That would be hilarious
Etna is in italy there are cirrently three volcanoes eruoting in italy
vid about greek deserts ?
Would you evacuate the million plus people around Mount Vesuvius and Campi Flegrei? Should Naples be evacuated?
Italy is trying to get the people who live closest to Vesuvius to move. I read they are offering money to help relocate people.
Naples would be affected most certainly and it’s dangerous because of the number of people living in and around there.
Their goal is to be able to evacuate those at risk in 2 days.
Thats the goal if the Italian government right now
I can't seem to find data that says anything about what has been the most and least volcanically active period (week perhaps) in the past 50 years by country of how many volcanoes are actively erupting over any given week.
I say 50, as anything longer than that may put us into a tech era where not all of the globe has been monitored to have seen all land surface eruptions. Probably would need to exclude any seamount eruptions.
50 years is not long in the geographic record but the question comes about simply because your reports are always started with mention of the number of eruptions over the past week. It would just be nice to know if hear there have been 40 actively erupting volcanoes over the past week that count is low, high or average globally compared to the past 50 years of monitoring.
I am not saying or even thinking that a week which has a large number of eruptions or a very small number would be indicative of anything but it might just be fun to know how any given week compares to any other given week.
The Smithsonian Institution has a publically accessible database of this sort of info on their web page. AFAIK, the number of erupting volcanoes in any particular day is usually between 40 and 55. Most often it's between 45-50, since that's the center of the bell curve. IIRC, there are about 1350 active volcanoes in the world, a quarter of them in Indonesia. I hope this helps.
Why haven't much US mainland volcanos erupted? Hawaii technically don't count thats in the ocean. Though that's US soil.
I feel the same. Hawaiian volcanoes, and really Alaska too, don’t really count. I view those as Hawaii and Alaska. The Cascades and scattered others in the Western lower 48 are what count.
The Cascadian Volcanoes are dependent on the rate of subduction of the Juan de Fuca plate under the North American plate, the rate and amount of partial melting of the subducted plate boundary, and the depth, filling rate, and build up of pressure within the underlying magma chambers that feed these volcanoes.
@@garrettfornea1088 I would argue Alaska should count as it is part of North America and thus is tectonically connected.
But if you exclude Alaska you are left with the Cascades and the volcanism associated with the basin and range province the Snake river Plain & Yellowstone, the Rio Grande rift valley the western and eastern borders of the Colorado plateau and Sierra Nevada Great Valley block respectively. For complex reasons spelled out in more detail below I suspect these will display episodic activity which could take many years for the next episode of volcanic activity to occur.
To explain how I reached that conclusion it is largely based on seismic tomography evidence that the vast majority of this volcanism outside the Cascades is concentrated along the area of the continent directly underneath the relatively linear transform offset solid mantle lower density sheer velocity discontinuity which corresponds to the East Pacific Rise when not beneath North America and neatly traces out the boundary of the Basin and Range province to Yellowstone to the Rio Grande rift valley before darting back west through Arizona and southern California where it emerges in the Salton trough and adjacent gulf of California as the East Pacific Rise. There is also a sustained largely differential clockwise rotation of the crust west of the Rio Grande rift valley which based on GPS is centered around Yellowstone with two only regions the Colorado Plateau and Sierra Nevada Great Valley block respectively rotating as rigid bodies explaining the two otherwise anomalous volcanic zones as they align to the boundaries of these wo rigidly deforming regions.
Note here that Yellowstone also falls along this boundary with its igneous petrology from Siletzia and Yakutat indicating it was likely originally a ridge aligned hot spot along the East Pacific Rise like Iceland is today along the Mid Atlantic Ridge and showing a consistent chemical evolution as it transitioned from oceanic mantle to increasingly continental mantle. So it appears they can be effectively treated as a single system with a deeply rooted fixed frame relative to North America moving SW. This EPR associated activity appears to generally have dates for eruptions at different volcanoes which are cotemporal or nearly so with episodic clustering the last of which was around approximately 1000 CE/AD or so.
Then we have the Cascades which are are notable for being a hot subduction zone with fairly buoyant crust with minimal water content to reduce melting temperatures compared to typical subduction zones. Additionally The high rate of sedimentation infill of the Cascadia subduction zone ahs resulted in thick deposits of these sediments which have already lithified siltstone and sandstone of Pleistocene age further insulating and weighing down on the subducting slab. This has the effect of extending the locked regime of the slab all the way out to the edge resulting in one of the largest locked regions of any subduction zone on Earth enabling vast amounts of strain to build up prior to a rupture. Because this slab is locked it is likely that little if any downwelling material is currently being forced out of the slab to induce melting which given the lower water content needs a higher temperature threshold to trigger melting in the first place. I thus suspect the Cascades will be fairly quiet until after the next megathrust rupture breaks the quasi equilibrium state established beneath these volcanoes.
I should however note that there is a conspiculous few volcanoes in the cascades which have been more active than the rest cough Mt. St. Helens. Notably I learned from a colloquium talk on Nick Zentner;s site this past acedemic year that Mt. St. Helens falls along a peculiar lineament which has and additional source magma composition chemically matching the Yellowstone hot spot. This unusual magma signature only began to be observed 5 million years ago and is only found along a narrow east to west lineament which extends both closer and further from the trench than is typical of subduction zone volcanoes and from seismic tomography corresponds to a thinning of the subducting slab. Given this is roughly continuous with the Snake river plain I suspect it may be a continuation of it i.e. the East Pacific Rise which has been reestablishing some original pre continental override boundary. This notion that this may be the original boundary comes from the observation of a strange v shaped notch in the ridge discontinuity corresponding with the Gouda ridge and the subcontinental portion just east of the southern cascades which is NE-SW aligned cutting from where the ridge dives beneath California up to the Snake river plain. This area is traditionally classified as either the Cascadia back arc or the high lava plains and is notable for its young basaltic lava flows. This subcontinental notably is based on seismic tomography also happens to form the eastern edge of termination of the Juan de Fuca slab beneath the southern cascades with no evidence for subducted slabs to the east of this boundary until one goes east of the Colorado plateau and the Rio Grande rift valley. Given that the direction of this offset directly matches the relative direction of motion of North America over the EPR system this is probably most easily explained by NA dragging the Juan de Fuca slab with it as it has moved SW over the EPR with the rigid subducted slab in turn pulling on the solid upper mantle discontinuity of the EPR. This is a very complex setting but notably the only portions of the cascades showing any sign of above normal activity in the last century fter the burst of eruptive activity in the 1700 through early 1900's are either along the lineament cutting EW through the cascades i.e. Mt St Helens or the back arc region i.e. the recharging/actively intruding 3 sisters volcanic system both of which show additional melt components beyond typical subduction melts.
Ergo I think the Cascades are dormant awaiting the next megathrust slip to reinvigorate the system with fresh melts as the plate descends. Everything else is linked to the EPR and relative motion between the EPR Yellowstone ridge complex and North America which is more or less episodic much like other MOR's just with an even longer periodicity between eruptive activity likely due to the thicker continental affinity of the overlying crust. Since the last eruptive pulse here was only a few thousand years ago it could be some time before enough strain builds to trigger the next major eruptive episode where intrusions are more likely to reach the surface.
All of them are in italy. I wouldnt worry about it.b
First like! But not first comment.
Humanity wtf
You butchered the pronunciation of etna's crater Voragine. You might want to spell it like Vora-gin-eh.
I don't mean to be rude btw
The volcano wasn't offended...
Manood ka malalakas na bansa
😎
Could it be magnetic poles reversal or earth axis moving?
No. It's a normal amount of volcanic activity, nothing unusual.
I was thinking it might have more to do with the Earth's core slowing and reversing. But I'm no scientist.
No. It isn't solar flares, the Aurora or elves either.
Have a question for you, Do you think the sun big solar flares affects the earth magma. Which is messing with the earths volcano's.
Solar flares do not influence volcanic activity.
USGS.
Let's all go to the Congo 😊
Mt Etna is in Sicily not Italy you said my parents were born in Corleone Sicily as theirs were
Sicily is part of Italy.
I love your videos but please move back from the mic a bit. The asmr kills me.
The gigantic underwater volcanos are waking up too. Things are heating up from inside earth guess what its not from cow farts!😮😂
I hope these Volcanoes are offsetting their C02 discharge.
I think the word paroxysm needs more emphasis. 😀Maybe shout it in future?
First?
Yes, here's your cookie. 🍪
The voice is muffled. Why?
Perhaps your speakers need to be replaced?
Nuestro gobierno no tiene idea de cómo la gente está sufriendo económicamente estos días en el mundo. gracias señora Regina Maria Howard imaginese invertir $4.000 y recibir $14.000. todos priorizan la inversión🇺🇸🇺🇸
Esta administración no tiene idea de cuánto sufre la gente, las cosas se están poniendo mucho más difíciles que no podemos soportarlo más. Muchas personas luchan económicamente para poder poner comida en la mesa y un techo sobre sus cabezas. Agradezco tu consejo, Regina. Imagina que invertí $2,000 y obtuve $10,600
¿COMO por favor? Sé que es posible, te agradecería si pudieras mostrarme cómo hacerlo
👏Llega a los 100.000 hoy. Estoy realmente agradecido por todo el conocimiento y las pepitas que me habéis brindado durante los ultimos meses. Comenzó con 20k en agosto de 2023.
😂sure
Sí, y eso es cierto. La actual economía global no ayuda.Tenga en cuenta que la gente realmente está triunfando en el comercio de criptomonedas y Forex.
