This Week in Volcano News; Magma Moving in American Samoa, Mount Mayon Unrest
HTML-код
- Опубликовано: 15 июл 2024
- In the last week, a series of magmatic earthquakes continued underneath three islands in American Samoa. As a result, the alert level of 2 of the area's volcanoes was raised from green to yellow. Meanwhile in the Philippines, a volcanic uplift signature was potentially detected at 2 volcanoes; Mayon & Bulusan. And, in Chile, Mount Hudson produced an unusual hybrid earthquake. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.

As a quick update, phivolcs just raised the alert level of Mayon from 0 to 1. In other words, what I thought was uplift truly was uplift!
So, near where I live in Humboldt County, California there are two small towns called Samoa and Manila, and I will probably be there tomorrow videotaping a new beach trail they just opened up. They are called that for the same reason that they used to have a statue of President McKinley here. It is because he wanted America to own both Samoa and the Philippines. If we owned the Philippines those people would be our citizens and we would be responsible for things like evacuations and Fema trailers for people living near them when they erupted like the ones in "our" Hawaii and American Samoa. A few years ago the city of Arcata, California voted to remove the "offensive" statue of McKinley from the center of their Plaza and give it away to Canton, Ohio where he was born and there is a museum dedicated to him. I made a video about this statue before it was removed, so when I started seeing news articles saying the statue was "missing" and Canton had not put it on display I actually called their Mayor and people from their museum and stuff and tried to investigate where it went. This was several months ago and recently I was astonished to see our local news run an article saying it's being put on display in Canton. I think I might have inspired them to actually keep their promise and put it up by calling them to ask why they hadn't because there was some statement explaining why they hadn't in their press release. I am going to have to explain all of this in what seems like it's not just gonna be a video about going to a beach because I can't go to places named those names without explaining why. The same people who massacred and oppressed the local Native Americans here fully supported McKinley invading all these countries and making them our land to the point where they put up a statue of him and named cities after the lands we were invading, at the time. That's why we have American Samoa and a city called Samoa and why I used to live in a "beach house in Manila," California. I cannot tell you how many times I have explained to people that I don't/didn't live in the Philippines. And why it was named that, to people who do not live in Humboldt.
I hope you'll visit Mayon when it erupt again, and I hope that she shows up to you. She is quite shy.
I hope it will not be explosive, you are welcome to stay and watch from our city in Legazpi when it occurs, currently it is not visibility since its rainy season here
I adore your passion, not only for keeping track of events around the world and analysing them, but also for posting on a daily basis. Well done.
Totally agree.. his passion shows in his videos..
I would really like an in-depth update as to why the Iceland volcano petered out so quickly. Especially with all the hype before it started.
I think most of us, as well as the Icelandic volcanologists, would love an in-depth answer to that… The Reykjanes Peninsula is feeding us surprise after surprise as it reawakens from centuries of slumber.
Keep an eye on the geo movement on earthquakes and their progression, should give a hint onto what is going on global geowise for the volcanoes as well.
Gakkel was involved this time...its all one great big suture really...
Love all the new lava flow footage that you shot in Iceland. So sad that that eruption is over after such a short life. Sniff!
I’ve always been interested in the inner workings of volcanoes,amongst other things, I never get tired of watching your channel. If you were my geology teacher in high school (1980) I certainly would have paid more attention. When Mount Saint Helen blew I did not realize it was possible the USA had such a volcano. Thanks again.
Um.... Usa has even more issues volcanoes than just mt st helens and the decafes volcanoes located hete, say hello to the caldera and mega caldera ones too like yellowstone, long valley, valles, that pyrmid lake one with the needles and the salton buttes.
@@razorransom1795 Ummm when your young you don’t really pay much attention to those things Mr perfect. Oh by the way I was WAY more interested in chicks then volcanoes. Weren’t you?
@@ot8210 Ahem, one Im a chick, two nope, was a bit of a educational geek and was deep into religious prophecies and their possible physical manifestations like geo disasters and effects. Yellowstone event March 17 2010 was an eye opener for me. Probably few realized what was really going on that day from 11 am to 3/4pm cause many were watching the parade, grandma just happened to watch her news instead and caught it. It inflated and was really close to erupting but the gases dissipated and it went back down. Started accidently and ended on purpose as a fracking news story causing cracks, but the middle was both frightening and awe cause the ground deformation looked like a hard ground plate on top of a staurated soil balloon. Then the show on Rome's gate to hell (actually greeks gatw to hell first) on pakkumuke fault and its co2 spring temple caught my attention, near where St Philip is buried. It is a stair step fracture rift, just like how the salton sea's and its actions caught my attention from 2010 to 2012 if not to 2014. Then found things on the african rift and the east pacific rise, and the pieces of the fallaron plate like juan de fuca major and its sub pieces of de fuca minor and such. As well as where it's sumerged pieces are under usa and its condition, as well as what that can all mean if those faults let loose and how it affects those mantle plumes and their volcanoes they feed up above. The so said traveling hot spot that was once under the new madrid now of the coast of south carolina? history of causing some od the worst ancient quakes for the new madrid, kinda keyed me in to the not really said truth of the size of yellowstone's plume after looking at a geology's professor's site on it, and it's connection to the new madrid north part, means future can be quite devistating. Keeping close eye on geo events and news like the volcanoes including the mega calderas and earthquakes globally and keeping tabs on their history and affects, globally.
@@razorransom1795 Thanks I will. # 1 I’m not to big to say I’m sorry. I lived in the San Fernando valley in Southern California for 60 years. Starting with the 1971 Sylmar earthquake I rode them all. The worst was the 1994 Northridge quake. I worked nights and normally stayed up until 2 or 3 am to be to work at 4:00 pm m-f. But on that night I had the feeling something was going to happen. Wasn’t sure what but I knew something was going to happen. Finally I went to bed about 4:25 am, I laid down and I heard it coming, this thunderous roar. Next thing I know I’m tossed outa bed on to the floor with all the stuff up on my dresser draws falling on me. I could not get up for about 4-5 seconds. Finally made it to the bedroom door but the door was was shaking so bad I could not open the door. Man, I’m screaming bloody murder. Finally got the door open, raced down the hall it took about 2-3 seconds to open their doors then it was over. I pitched my tent out front of my house and lived outside for a month. Fully dressed. Finally I made it back into the house, but still slept fully dressed for about 3 months with my shoes on the floor just in reach. My wife thought I was crazy. That was the only earthquake that I thought life as I knew it was gone forever.
@@ot8210 Thx for sharing that info. Heard of the northridge quake but I don't think Ive heard of the Sylmar one. Like to keep tabs and loom such info up cause some of the precursors and events could help others reconize pre or during others what is going on, and ya never know if some of its traits will pop up in future geo events, and know how to survive and deal with them will help others in the future. Im thinking we are in the wind up of several bad geo cycles if not all merging into a cacylism level geo cycle. And by know every spots geo history and seeing if their are any similar traits or structures may help others warn them away from such danger and know what to expect. Thus why I love ixelqndic saying of living with fire under our feet, in a way that also goes for faults too cause some do have plumes and magmatic pockets under them. And knowing many catholic saint and visionaries prophecies and visions on future events, many major geo events go on in them, so we are getting really close to their happening seen time. Campaii and colini albani go off before the yellowstone major one. Vesuvius before them ( Im thinking a loa kilueaha relationship between ir and campaii) , though not sure yellowstone could have a minor to med one before then like taal and some others have been doing now and since 2016. Apparently sakujima or cherry blossom island with its decade volcano is also known as aria caldera aka japan's mega caldera or also known as super volcano. Thinking many others will reawaken, and ancient ones both volcano and faults may resart too, have been for a few years already, and new ones form like even now. It's been interesting seeing these huge vapor plumes and steam vents coming out of the appalachian mountains and mines, faults and drill hole areas for at least three years now like 2019/2020 to now. Salt taste from them was strong in 2021, pending on area now, wonder how much alantic and pacific getfing sucked under and if the alantic is going into old ocean phase then.
I hope you’re feeling better. This was an interesting update
You do a clear explanation of geologic incidents. Consider doing a series of nomenclature videos. For instance: "What is magmatic uplift" with examples from the incidents you cover, or "What is a Plinian eruption" with real life examples. You already do this generally in your videos but I'm pointing out a more specific series creation with the nomenclature in the title. The idea is if a lay person hears the term 'Volcanic Hair" for instance and searches for a video explanation, your series would appear. It would be a service to humanity in a way but only do it if you do a couple of the series videos and find it rewarding. And this is just a suggestion of course which may or may not hold merit.
I would love to see a video explaining the different kinds of eruption.
I agree. As a retired college professor, I know that an introductory course is full of the vocabulary of the discipline. Most of us could use a geology vocabulary reference.
@@PSciDoc My geology classes were so long ago that a lot of new things have been learned since I took them. A refresher is in order. :D
@@mbvoelker8448 their magma content, their damage and history rap report equalvent, and maybe their gas content and possible causes.
He has already done those, just search for it.
Just had an earthquake earlier this morning in northeast Arkansas. USGS measured it as a 3.1 with a depth of 16 km. The epicenter was near the town of Imboden, which puts it in the New Madrid Seismic Zone.
Great work! When you use google Earth , when zooming in could you always zoom in with a view of the whole planet so we could see where in the world you are talking about? Thank you!
Nice update 👍👍👍
Good to note, Saunders is definitely not in the UK, but in the South Sandwich Islands.
It's unfortunate that the new Fagradalsfjall vent didn't last long. However, it seems there is a whole lot more activity occurring elsewhere in the world. Always enjoy following your updates.
I just love your reporting, my fellow Arizonian. I'm moving to a boarding school gig on the California side of Lake Tahoe. Could you maybe feature some Sierra geology soon? It's a brand new clean slate in terms of my knowledge. I'm going to go back into your content to see what you've already done. I'll be living near Donner Pass! They got 17' of snow in 30 days last year. Brave new world!
You are moving to a large volcanic complex.
Is there any update on the potential supervolcano in alaska(mount cleveland)?
Can you please make a video on the explanation of the mountains between Albany & Eugene Oregon right off of I-5. It looks like a bunch of cinder cones are all over the area but must be really old. Thanks love your videos!
Mayon seems to have a tradition to erupt within 5-10 years period
It's lava fountain is somehow spectacular to see.
It had a near continues eruption since 2000s with several short-term pauses between 3-4 months of each year. the final eruptive phase ended in the middle of 2018 just exactly a year prior to taal's turn when this small volcano acted in the middle of 2019 (developing unrest) until it blew its top on January 2020. during those times, Mayon was kept on alert status but no significant changes has observed throughout of the year. it'll later downgraded to normal (alert level 0) on July 30th, 2021 thereafter. the volcano went stable about a year prior to this moment when the alert level ascend to 1 (abnormal) from 0 (normal)
4:11 ; Reminds me of the little lake in USS Calister lol ! Thanks again for this informative video ,Sir !
Could you do a video on how the gasses released by these volcanos effect the atmosphere.
Can we estimate how many volcanoes are erupting under the oceans?
Lots 😁
It's been about 20 years since I took geology, can you tell me if this is an "average" number of volcanic activity or what the norm is? I recall there's like 1,300 - 1,500 "active" volcanoes (and "active" doesn't mean what laymen terms would mean).
It’s average.
Mount Hudson, a somewhat unknown volcano whose high-end VEI 5 eruption in August of 1991 was overshadowed by Mount Pinatubo’s infamous VEI 6 eruption in June of the same year. Just a question : When was the last time Mount Bulusan erupted lava ?
Around 200 years ago
Ah, yes, 1991 mini year without summer to 1992/3. en.m.wikipedia.org/wiki/Mount_Bulusan
Campi Flegrei will most likely erupt within 100 years the uplift has started back.
The concrete is what made it hold up so much right? So the eruption can turn out to be a mid vei 7.
Do you think the eruption in Meradalir is done for good or that this might just have been the end of a small chapter?
At what timescale? I'm pretty certain this area will be active for thousands of years. But this year's show might be over.
I think he talked about how often it erupted in an earlier video and IIRC it was every 600 years; however, each eruption may have spanned multiple years.
I wouldn't trust Mt Hudson right now even it shows green status. Scary potential...
I saw 2 moderate earthquakes in Iceland today, is it connected to the volcano?
I've always wondered, has anyone recorded a caldera forming event?
Krakatoa 1883 is one such event. Surely, there are others.
Does Mt. St. Helens count?
Hunga Tonga formed a caldera. Mt St Helens formed a collapse scar, not a caldera.
@@independentskarab7775 St. Helens needed to go deeper?
The mechanism of collapse needed to be different. Instead of a landslide directed towards Spirit lake, Mount St Helen’s top needed to collapse into an empty magma chamber. Mt St Helens’ magma chamber never emptied enough to produce a collapse, so it never formed a caldera.
I think that some of the local people that survived the Tambora eruption did provide some description from their own location.
Edit. Just found the scant details provided by the Sultan of Sanggar just before he took his leave of the area.
You can find it and other descriptions from further afield in chapter one of Gillen D'Arcy Wood's book, 'Tambora The Eruption That Changed The World.' Along with Wolfgang Behringer's 'Tambora and the year without a summer.' Where you'll find reference to it in chapter two. 👍
I really enjoy your channel. I always click "Like." But I wish you would consider saying both metric and English when you give distances. etc. Thanks for a very informative channel.
What is the average number of active volcanoes on any given day?
About 40-50.
BRING IT ON!! THEY CAN TAKE IT!!!
I have been wondering about the huge circular formation located at 43 deg. N. 121 DEG. W. At first I wondered if it was a crater but it looks like a raised formation rather than a depression. I find it interesting due to how round and large it is. Is it the base of a super volcano?
Seeing as how it’s located between the Newberry Volcano and Yamsay Mountain, both of which are shield volcanoes, it’s most certainly volcanic. I agree though, it’s odd. Newberry is known as the widest of the cascade volcanos but that circle almost looks larger. Maybe it’s the remains of a long dead shield volcano that’s been ground down by glaciers and forgotten since it’s extinct and not a danger. The Cascade Range is full of those
It isn’t volcanic, it is formed by a pattern of volcanoes which are positioned in such a way that connecting all of them would produce a circle.
Any chance that island in American Samoa will do a Santorini?
you mean it will form a caldera? no i think it will be unlikely because it is a shield volcano and it already had a collapse scar
Are the mainland U.S volcanoes gonna produce any action?? So much mystique. 3 entire super volcanoes in our backyard. That's bonkers!!
Other continents have more active supervolcanoes.
worried about the American Samoan people. One of my co workers mentioned that with the rising sea level where their house WOULD have been is now submerged. And with an eruption possible it would be explosive hybrid :(

If you are millionaire's or billionaire u should help poor people and needy.In this world we must know to help people
I look forward to your updates. You use science for videos not a smart mouth as some do.
Just think if Elon Musk got into the volcano monitoring business. He would literally have unmanned planes flying around volcanos 24/7 dropping sensors and recording data, and having detail stats uploaded constantly. Volcano unrest? Just call in a drone and elon sends one in within a few hours. lol
