The Active Volcano in El Salvador; Izalco
ฝัง
- เผยแพร่เมื่อ 30 ก.ค. 2024
- In 1770, a brand new volcano appeared to the world in a populated area. This did not occur in Mexico, like would later be the case at Paricutin, but rather in El Salvador via what would later become the more than 2,000 foot tall Izalco volcano. And, this was no mere cinder cone, but a truly new volcanic system. This video discusses this fascinating volcano, and gives an opinion on whether Izalco will ever erupt again.

Only on this channel is a volcano ceasing it’s eruptions filed under “Disaster struck”. Love it! Thanks so much for the prodigious and high quality output of this channel!
I've heard the day the volcano stopped erupting was the opening day for the hotel. That's probably why it's considered a national tragedy 😂
He probably meant disaster specifically from the viewpoint of the tourism industry surrounding the volcano.
Gosh your audio balancing is absolutely perfect. Thanks my dude.
Thanks! Young volcanoes are fascinating! Examples of these are of course, Izalco, Klyuchevskoy and Bagana, although I may be wrong about the latter. It is also very uncommon to hear about a volcano's exact birth date! The several, hitherto undiscovered minerals at the Izalco volcano are truly amazing!
There is way younger volcanoes than the last 2
@@EperogiLimousine True, but Klyuchevskoy's altitude at this young age is pretty remarkable!
One of oldest memories of learning about volcanoes as a child, was an illustration of the newly growing volcano in Mexico. And yes I'm that old. 😁
it's crazy to think of the young age of this volcano. the weirdest thing is the fact that it doesn't even share the same magma sources as the nearby volcanos.
Do a video about Nicaragua's Cerro Negro cinder cone that was born in 1859 that has has multiple eruptions
Thank you for using my request. Izalco is truly a fascinating volcano. Everytime I visit El salvador, I always love to see it and its beauty. I can see that Izalco has many fresh lava flows. Can you make a playlist for El Salvador Volcanoes. I wonder if there are supervolcanoes in El Salvador, I think the only one I have heard about is Ilopango. Keep up the great work.
How do these volcanoes being so close have different magma sources? Can you explain this? Separate magma chambers? How could there be separate magma chambers with out communicating? I’d think if it is big enough to cause an eruption it would be running into anything close to it.
Always edifying.
Great video!
A request - I'd love to see you cover Orizaba volcano in Mexico (I don't think it's been done yet, as far as I know).
Keep up the great work!
Hello! I have been suggesting Pico de Orizaba for months but he simply won't cover it :( nor any of the Mexican Volcanoes. Even though I find these volcanoes fascinating, they just might not be of his interest. We'll keep on waiting :(
Wait. If the last eruption was sourced from the bottom of Izalco's magma chamber, which had been undergoing fractional crystallization, according to Bowen's Reaction Series, the more mafic minerals of olivine, pyroxene and calcium-rich plagioclase (such as anorthite) would have been removed from the melt, preferentially removing iron and magnesium and some silica, while leaving behind a more felsic melt (as silica makes up a higher relative percentage of the melt once those mafic, high-iron/magnesium and low-silica minerals have crystallized). Should that component then be erupted (leaving behind the more dense mafic material that has already crystallized), I would've expected it to be composed of andesite or possibly even dacitic andesite.
This is like when Kilauea, in its 2018 LERZ eruption, erupted andesite from Fissure 17, in an apparent first for the volcano (or at least the first time it has been documented). A previous intrusion brought basaltic magma to the LERZ, and there it sat, for a long time, losing mafic material and becoming andesite, until a new intrusion brought the heat and pressure necessary to mobilize the andesite that, otherwise, would've just become an intrusive rock (gabbro) had it crystallized completely. You don't get more mafic magmas from fractional crystallization, you get more felsic magmas.
name checks out
Would a new volcano that appeared where another had previously been really be a new volcano?
If a volcano is determined by it's lava source, when that source vents elsewhere is that the same volcano or a new volcano? And, c what about when the lava source itself moves relative to the surface?
I remember having the same discussion about an ash tree my dad cut down that grew back. New tree or old?
It’s more important what the geochemistry of the volcano is rather than its location to determine the number of separate volcanoes present in a region.
Almost certainly gonna be a very large eruption there or nearby eventually. Great video, topic
Based on what I've read in the literature I suspect its honestly more complicated for volcanoes one reason why chemistry is considered the main indicator is that it indicates a shared magma reservoir but when an area is densely packed with different magmatic intrusions of different chemical evolutions they can mix undergoing more dramatic transformations which seem to contributed to large voluminous explosive eruptions in particular.
Some famous volcanic systems such as Mt St. Helens will even erupt lavas with chemically distinct source melts in short succession.
A particularly noteworthy example of a complex eruption is Novarupta which is generally considered a separate volcano however from the location and overall event structure it seems more likely that Novarupta is the result of a magmatic intrusion from the Trident volcano extending into and breaching Katmai's magma chamber and inducing convective crystal fractionalization as the two chemically distinct magmas mixed while creating a conduit for Katmai's magma chamber to rapidly breach the surface and depressurize thus leading to a summit caldera forming on Katmai. Ultimately the location of release was on one of Trident's main rift zones while the caldera formed at Katmai's summit and the magma seems to have been a chemically evolved complex melt which it seems is the norm for large siliceous volcanic eruptions of VEI 5+
Taupo's last VEI 8 eruption for example involved 4 chemically distinct magma bodies which only briefly mixed for a matter of years to centuries before the latent heat released by crystal fractionalization lead to the over pressurization of the melt complex.
Even the recent Hunga Tonga Hunga Ha'apai eruption prior to the breach of its magma chamber by water it appears had involved two chemically distinct magma bodies coming into contact and chemically mixing so it appears to be likely that two or more adjacent chemically isolated magma bodies are a critical component in building up the large pressures on short timescales needed to make such voluminous eruptions occur.
So it appears from magma chemistry of large explosive eruptions in the past few million years that the more chemically distinct magma reservoirs in a region the more likely a large voluminous explosive caldera forming eruption is to occur potentially with little to no warning as the mixing timescale appears to range from a few years to centuries (i.e. less than a few thousand years).
Traditionally each reservoir and their resulting mixing products would be considered separate volcanoes with the results in the aftermath of such a large mixing event being known as large siliceous caldera complexes
Hey, so Novarupt and Katmai are essencialy the same volcano? What about Vesuvius and Campi Flegrei?
there are very few places immune from volcanic intrusions.
Comments for the algorithm!
3:58 Why do you think that?
And how far do you think we are from its next eruption?
And how big do you think it will be?

The accent over the first letter "i" in Parícutin indicates that the second syllable bears the primary stress, with the fourth syllable bearing a secondary stress. Therefore, Parícutin is not pronounced "par-ee-COO-tin" but "pah-REE-coo-Teen".

Volcano stan
Bro, he's an volcanoligist
Oh, dear.
Should I be embarrassed that it wasn't on my mind that Izalco is a distinct volcano literally on the southern flank of the also still active Santa Ana volcano? Because, I was pondering which kitty video to watch next, or, maybe an TH-cam scam fighter, or maybe seeing if AdBlock has a work around for ads. I can't remember now.
disaster struck... the volcano stopped erupting. there is something inherently wrong with that sentence.
it had me too, it's a trolling device (the real disaster was in 1927 with the deadly Vulcanian eruption)
remove such ridiculous restrictions on collecting...
we all are earthlings... why the hell shouldn't we be allowed to bring a rock or sublimate IF WE SO WISH
in my eyes it equals telling a person not to breathe on certain places...those making them rules should be ........
Really fun watching AI...NOT
The last story always makes it f****** hilarious to me.
The reason why it's forbidden is because they want it not because it's bad.
