Mayon Volcano Eruption Update; Strong Earthquake Swarm Occurs, Lava Avalanches Continue
HTML-код
- Опубликовано: 15 июл 2024
- On two recent days, the Mayon volcano produced more than 100 daily volcanic earthquakes. Since Mayon is already erupting, this has led to some people speculating that a new batch of magma might be moving underneath the volcano. However, I disagree with this assessment, and will explain my own opinion on what caused these quakes. Additionally, as the eruption of Mayon enters its 23rd day we now have an updated and more accurate lava flow map.

that is one heck of an increase. It would be nerve wracking to live near the volcano. I wonder how inured to the danger the locals are, given the constant small eruptions they experience.
I would expect many of them to be immune to it by now.
This is fine 👍🗿
@@RoseNZiegWhile writing this the volcano's steam activity increases and the steam gets more thicker creating a plume .
We visited the Philipines in '79, and had "dormant" volcanoes pointed out to us .. some dormancy: they were all smoking!
So yes, I'd say they're desencetized to them.
I live pretty near (kind of but I still live kilometers but my aunt lives in Guinobatan which is pretty near). They said that its pretty much a drill for them and they're used to it. Still the ash accumulation in their houses are still a pain to clean especially some children have asthma. Luckily it rained this past few days so the risk of ash inhalation isn't a concern now. The only problem now is the damages that the ash caused to their crops. There's still more to salvage but they're experiencing considerable losses.
So interesting! I never would have thought that rain could cause earthquakes! You make it all so clear! Thank you!😃👍🌟✨✨✨✨
An expanding gass pressure with no escape can pose a huge danger. Learned it the hard way when I tried to play as a kid in our shope and tried to inflate an old tire lying around on my father's shop that I'm going to use for our pool. Had near death experience when the shrapnels of the tire made a near miss fly by on the side of my face. Luckily I walked a way without a scratch. Got slap marks on my butt though because I "tried to help" in the shop without my dad's consent.
Thank you. For your professional updates. Peace.

Liquid hot. 😅
@Geologyhub. There is an impact structure near St Martin Manitoba, Canada. I'm not sure how much is known about it, but it's big and it's circular!
Interesting. Do these changes to the hydrothermal system increase the risk for magmatic and phreatomagmatic events, or is that not a risk here?
Thanks. To those near the volcano, never be hard-headedL
Welp several pyroclastic density currents just occurred in the past few hours. And our local government institute on volcanoes just issued a notice on increase volcanic activity.
🌱🌏💚
The rain causing earthquakes is such a logical explanation, I'm amazed that someone actually figured it out. I mean, who would've thought?
Scary when it's from a high altitude volcano with that shape.
What is the most interesting volcano you have researched?
I would love a detailed video about isostasy?
What is in your opinion the most dangerous volcano that is not considered a decade volcano?
I live in the philippines I hope those people are okay because some people are right next to the mayon volcano🌋🇵🇭🇵🇭🌋
This raised a question, how does water content in the lava effect it's viscosity at the surface?
Water in magma is in the gaseous state.
The viscosity of lava is more to do with its inherent Silica content. The lower the silica, the more fluid the lava is. Groundwater doesn't mix with the magma directly since it gets superheated and turns to steam, but an additional hazard is created through phreatic eruptions since the superheated water becomes highly explosive.
Are the temperature variations of the magma different enough to effect the flow of similar compounds?
@@kswsquared I had to look it up, which I didn't want to do. In fact, water can make up to 6% of magma, but that's not my question. It definitely affects viscosity, but I'm going to have to read up on it. I don't have the time to dive into a complex area of geology.
@@guylelanglois6642 See, that's what got me started. I'll have to watch the video again and see if I understood what GeologyHub was saying about viscosity and temp. 🌎🌋👍
Water is crazy if you think about it.
Whats going on with Iceland? I've heard of more earthquake swarms being detected...will there be another eruption there anytime soon?
~✨PRETTY✨~
What are the long-term effects of pyroclastic flows on Mayon
Filipino seismologists mentioned that there's a new magma dome
Do you have a video explaining SHALLOW vs DEEP earthquakes? #Goethermal #PlateTectonics #Vulcanology
It’s quite simple: shallow= shallow, deep=deep
@@EperogiLimousine you are very wrong. I have done some homework since then. Stop trolling intellectual conversations that do not concern you.
P.S. Enjoy the collapse of the 🇺🇸, NATO, and the collective West.
1.Empires are determined by the youth of it’s workforce. The average population age in Africa is 19. The West is pushing 40. #LastShallBeFirst
2. Africa was prevented from participating in the WESTERN economy and thus has ZERO 🇺🇸 💵 debt. Meanwhile, the West is $32 Trillion in the hole. #WealthTransfer #Dedollarization
3. Africa is a GIANT plateau. The West has ignored climate change and when the #DoomsdayGlacier melts, it will be the ONLY continent where the cities are not flooded.
4. 97% of ALL fertilizer is in Africa. #Famine
5. 60% of ALL undeveloped arable land is in Africa. #GoBackToAfrica
6. BRICS will add Mexico, Iran, Iraq and Saudi Arabia. Who in turn will cut off ALL oil to the West. #EconomicIsolation
7. AFRICAN nations are giving free VISAs to “call back” it’s diaspora. #Reparations #Exodus
8.But look on the bright side, at least “We” the blacks will simply walk out and #GoBackToAfrica. While the 26 million Mexican and Latin American undocumented workers (that we know of) continue to be imported en masse and alienated by people that do NOT want to pick their own crops.

As a Resident of Filipinos, no people were injured/died, every people in Albay ,Philippines Mt. Mayon was evacuated safely, I do not live near Mt. Mayon or Manila ,Phillipines.
Aka hydraulic fracturing but with steam.
Do a video on the largest impact crater within our solar system. I know it exists on the Lunar South Pole.
San Andreas Fault -- Can large faults be affected by heavy rainfall, and if so, what is the mechanism? I've lived in Southern California my entire life and have associated some quakes with rainfall... Am I nuts? SoCalFreddy
The San Andreas Fault is not a hydrothermal system. However, small quakes can occur when hillsides are water saturated and slide down.
So is the reason this lava flow is moving so slow because it's silica rich(rhyolite, andesite) or because the flow is little and not pumping fast enough?
The viscosity of the lava determines how fast it flows. And the flow is determined by the silica level. Basalt is low compared to Andesite, then dacite and finally rhyolite which has the highest level of silica. And the higher the silica level the more explosive a volcano can be. That is because a more viscous lava tends to clog up a volcano vent resulting in an increase in gases in the lava. And that gas pressure will increase until an eruption occurs. This volcanoes with more silicic lava tend to be more explosive.
@@michaeldeierhoi4096 right so this eruption hasn't been explosive but the lava hasn't advanced very far. So what you think the reason is?
@@knightmarefishing It's hard to say for sure. I tried research the lava type from Mayon and it's part Andesite and a couple of lesser known minerals augite and hyperesthene and it's not clear why that composition of lava would flow slowly. I'm sure Tim with Geo Hub would understand better.
@@knightmarefishing it’s Andesite, just because it’s not exploding doesn’t mean it’s not andesite
Let us hope that Mayon DOESN'T have a fresh batch of Magma intruding into it! Those viscous, gooey magmas can be especially dangerous when all signs point that an Eruption is ending!
"most perfectly"
"most perfectly symmetrical", anything wrong? Although, Guinness World Records listed Mayon as "most conical volcano" in the world.
@@chickenjoy 'Perfect' and its derivatives are non-modifiable. Something is either perfect, or imperfect. So, the adverb, 'perfectly' also cannot be modified. It is a nonsense word, best evidenced by simply removing it from the sentence: "most perfectly symmetrical" versus "most symmetrical." It's garbage writing and shitty editing. A decent editor could reduce his word count by about a third and double his perceptibly compared to the "more-is-better" word salad that he serves up every day.
@@snarky_user Ok, perhaps it's fine for non-formal articles or poems?
What a narrator
So with all those earthquakes, we should see some information surface (see what I did there) about the active tectonic plate movement and a statement regarding how much the island has moved closer to another body of land right?
I'm not holding my breath, because we always hear that volcanic activity is the result of plate shift and it's brought up when the explanation for plate shift theory is talked about but when we talk about an eruption of a volcano we seem to mention plate shift only briefly along with fault lines.
I honestly would have thought that when we have an active volcano on an island, we would be keeping a vigilant eye on the exact location of the island in question! Surely there must finally be empirical evidence of actual plate movement?
Because either tectonic plate shift theory is true and correct and volcanism is the result of this or there's something else that's the driver behind volcanoes and we don't really know what that process is because we have stopped looking...
You know, it's exactly like religion when you have a question but you have been told to have faith...
Is it ethical to ever stop asking questions? I really hope not!

The emptying of the magma from under ground, of course, wouldn't have anything to do with earthquakes 😊. It has to be the rain. 😂. Love all living things unconditionally and forgive all things forever and leave the world and worldly things. This is the only way. They are all out to fool you. 😢❤
When magma moves, the ground has to adjust to fit the magma, so yes magma chambers do have something to do with earthquakes, try again
Not true.
Well that's an enlightening addition to this comment section
Oh sorry he’s wrong *volcano goes to sleep because of this comment*
I know this is a learning place but I can't help to think that the election of a Marcos is responsible for this.
How, though?
@@asherikamichaela8425 well it was a thought and we know there is no coincidence .
@@cyankirkpatrick5194 It happened too in 2014 during Pinoy time and in 2018 Duterte. Stop the cap and move on.
Did you not say this on another video?
@@EperogiLimousine I don't think so which one?
