Wow! You can find peach springs tuff all the way down in Superior, AZ alongside Apache leap tuff, which you can find beautiful clear obsidian in! I didn’t know it was from a super volcano!
I was unaware of the release of this video until this evening. It's an interesting coincidence as I was just driving through Kingman four and a half hours ago as I made my way home from an event in Utah. I noticed the volcanic features in the road cut, as well as what I suspected to be a large dike in Kingman itself, and was planning to look into the feature next weekend when I had time for my geology hobby. How fortunate for me that this is the first suggested video I saw on TH-cam when I got home.
Little bit of feedback. The reddish orange frame - it looks really good, but when I glanced at the thumbnail my knee jerk reaction was to mistake it on the bottom for the red TH-cam stripe that means I have already viewed it. The only thing that made me double take and actually watch it was stopping to read the title and knowing I would not have forgotten that if I already saw it because it’s local (ish) to me. Then I looked closely and noticed it was framing not just on the bottom. I worry you will have viewers accidentally not watching episodes. Love your channel. Keep up the great work. I always enjoy your content.
I live in Flagstaff Arizona. We've got Sunset Crater near us, which erupted approximately 900 years ago (a very young eruption in geologic time). Never knew about this volcanic activity near near Kingman. I drive thru that area about once a month. Will try to check it out when I pass through next month. Thanks for the very informative video.
I live in New Mexico and see the view from my house lava flows that came from the Jemez volcano. I also knew that a large portion of the Jemez Mountains contain a valley and river that was carved by that volcano. What I did not know was that it has been considered a super volcano although I did know that it was quite large. The Valles Caldera that you talked about is a very large (miles in diameter) grassy area surrounded by pines. It has been used for grazing and now as part of a National Monument is forage for elk and deer. New Mexico is very volcanic. Lots of basalt and lava features. I also get to watch the sunseting from my house. During much of the year it sets near or behind a several hundred foot ancient volcanic plug creating an iconic South Western sunset. I grew up in Hawaii and am quite familiar with volcanos a the landscapes they create. So when I came to NM I was delighted to see so many volcanic features!
And to think the Valles Caldera is only about 1/4th of the actual Caldera. Redondo peak is a resurgent peak kinda in the center- south part of the Caldera. 70ish years age there was a "resort" featuring yellstone type of thermal features. Rumors have it that there was a geyser in that area that quit around 1900s, something that I have never verified.
The Springerville Volcanic Field is supposed to be connected to this super volcano in New Mexico. I'm 13 miles from Show Low and there are lava tubes in Show Low.
The largest supervolcano and resulting Caldera is the whole San Luis valley of southern Colorado .It was so huge it accounted for the Rio Grande rift. Can you please do a video on this ?
I've read that Guffey, CO sits on the rim that was a super volcano & there was a really huge eruption millions of yrs ago. Since there are so many dinosaur remains to the north & west of that area (as well as Florissant Fossil Beds National Park) we know something had to have happened.
I was just about to search for the Silver Creek Caldera and this came up. Been looking to see where a nearby volcanic deposit came from that wasn't from the Tome hill area. Thanks.
Thank you I was looking for something about this on TH-cam a few years ago and found nothing. I grew up in this area and still live here and we were all told in elementary school that we live in this volcano
Can you do a video on the volcanic area in Massachusetts? I know it’s pretty low with information but people say that there was a super volcano in Maine. I don’t know if there’s any way for you to do it for you on that that would be great.
I'd like to see a video of the Dotsero caldera in Colorado. I go fishing there all the time at the Colorado river. There's igneous boulders everywhere and a whole mountain of ash close to State Bridge Colorado.
I grew near Kingman, in Lake Havasu, and you can see those stratified layers along the Colorado River nearby. Same when you drive on I-40 through Kingman where the highway cuts through rock. Even prettier along Az-95 between Parker and Lake Havasu where you can see red rock. It's the most beautiful part of the desert there, but sadly a horrible place to grow up. Residents have no self-respect and respect nature even less.
In northern Arizona we see the volcanic and marine history of the area. The Sacred Peaks and cinder cones being evidence of vulcanism, and to the northeast are marine fossils. It is a fascinating place to be!
I was flying from LA to El Paso and all the hills I drove by were ancient volcanos. Looking out the window of the plane I could see the cone at the top of each one.
1,800^2 km of erupted material in 10 hours or less... And just a few weeks ago i was amazed by one the Taupo eruptions due to it's rate of ~100^2 km of material in less than an hour...
When you zoomed in on the highway cut, the first thing I noticed was the disruptions in the ash layers. Crustal extension faulting, or some other local activity?
I'm surprised, but this planet has surprised me entirely. Thank you for mentioning that extinct volcano in Alabama I would have never known about that. Because they have taught us that if we be quiet we can win the civil War which ended 150 years ago and the south lost humiliation all around 🤦🏻♀️🤦🏻♀️😞
QUESTION: Is the Kirkland Tuff from the same eruption as that deposited around Kingman? ECOMATERIAL Technologies is currently mining this deposit of pozzolan to enhance concrete mixes.
So, this supervolcano falls within or "soon" after the big ignimbrite flare up in the Late Tertiary? That same period includes La Garita and several other supervolcanic eruptions all over what is now the American West within a geologically short period of only a few million years. Do we know anything about what deeper processes might have caused that huge burst of large eruptions?
I don't think there is an agreed upon cause however based on the crazy Eocene series from Nick Zentner there does appear to be an age progression within the Laramide and associated volcanic arcs starting from the late Paleogene into the early Miocene with the volcanism geologically coinciding with the exposure of metamorphic core complexes also within the Laramides. The general picture I get from this is that we know these two processes occurred relatively simultaneously with a age progression along what had been a towering high continental volcanic arc under compressive strain for some reason or another began to collapse which appears to be the cause of both this extreme and increasingly siliceous volcanism and the exposure of deep metamorphic core complexes as the orogeny fell apart into Graben horst type terrain to some degree. The tricky part is why this change happened. One camp argues the Laramides simply just became too tall/overthickened and collapsed under their own weight and we don't need any other complexity but another picture accounting for the underlying slab which ca still be observed via seismic tomography notably with evidence of tearing and or detachment suggests the detachment and or breakages within the Farallon slab probably played a big role in this picture though telling when such events in the upper mantle took place is tricky especially since the underlying geology of the west coast of North America has turned out to be far more complicated than had been expected with evidence for lots of intense geological dynamics over the course of the Mesozoic and early Cenozoic including an unknown number of arc collisions and accretion ranging from oceanic to continental with variation chemically suggesting that the original arcs have been shuffled around and broken apart over geologic time, with even evidence for sinistral motion, pulses of volcanism with arc advancements and retreats and quite probably even lateral movements in crustal blocks, not to mention Siletzia and the Yellowstone hot spot, or even the broader and generally quite complex larger Pacific front as a whole all being dynamic in ways which are hard to understand/interpret. If I had to make a more general informed guess it probably had to do with the broader rearrangement of the Pacific plate as the collapse to the Northern extent coincided with some fairly extreme rotations and reshuffling of the position and type of fault boundaries along the Pacific around the same time as the Paleocene Eocene Thermal Maximum. This was a very chaotic time geologically what with two Large Igneous Provinces forming relatively contemporaneously along oceanic ridges (or what would become an oceanic ridge as the North Atlantic Large Igneous Province formed along failed rifts between Greenland and Eurasia which had then been attached and Siletzia/ Yakutat terranes which appear to geochemically share the same origin separated by seafloor spreading and subduction among other things as the collapse in that part of the greater Laramides was timed with the movement/detachment of part of the old Laurentian shield of North America and the accretion of Siletzia. Regardless of how it started once it began it slowly propagated to the south through the Eocene and Miocene. The parts in states along the American southwest notably Arizona Colorado New Mexico Utah etc. happen to be the youngest and thus best well preserved portions in terms of volcanics (the evidence for these volcanic episodes to the North are largely igneous features like dike and sill intrusions, batholiths and crystalized deep magmatic conduits (most notably Devil's Tower in Wyoming which is composed of hexagonal pillars of Phonolite a type of volcanic rock associated with stratovolcanoes most notably mount Erebus. How that earlier volcanism relates to the later volcanism is tricky though as it propagated into the older more continental parts it definitely got more silacious in composition. It will be fascinating to see what more comes out of the study of this extinct arc
Jim Scymanky and his three logger colleagues were caught in the blast of the 1980 eruption of Mt. St. Helens. All of them initially survived, but within days Scymanky's colleagues eventually succumbed to their burns and ash inhalation. Scymanky himself faced a long and painful recovery over the next year-and-a-half with many reconstructive surgeries and skin grafts. So it's technically possible to survive depending on circumstances and luck... or lack thereof.
Do know anything about Saddle Mountain In Tonopah, Az? Was it also a volcano? And also in Acton, in California. The reason I’m asking is because in Saddle mountain is known for it’s fire agates and Acton has also agates. Thanks
ive always wondered in the caldera collapse resulted in area over the lava chamber that allowed future eruptions/gas to vent more easily due to all the structural fractures, thus reducing the chance if a repeat super eruption. so when the empties lava chamber refills, instead of gas becoming trapped and pressurized until massive explosion, the gas is able to leak out through cracks created by caldera collapse. the gas being able to leak then results in lower severity eruptions after the first big one, until fresh uncracked crust covers the mantle hot spot via tectonic plate movement. or does the caldera collapse happen in an environment so hot the collapsing rock is completely melted/fused into a new gastight cap?
I’m curious - when a magma chamber is drained and the overlying rock collapses downward to form a caldera, what exactly does that process look like in real time? Is it gradual or in one sudden and devastating drop? What happens to the material in progress of erupting as the caldera forms, assuming it is still being emitted by this point? I would love to see a video explaining this process. Thanks for putting this channel together - it’s very informative.
Varies. Some of the controlling variables in how fast a caldera collapses is the amount of erupted magma, the intensity of the eruption, the shape and size of the magma chamber(s), the amount of water and other volatiles involved in the eruption, and the chemical composition of the erupting magma. Hunga Tonga took less than an hour to collapse earlier this year, Pinatubo in 1991 took several hours, and Kilauea in 2018 took days.
I’m so confused as to why these videos consistently forget to mention, superstition mountain as a super caldera as well. It’s one of the few largest on the planet. I’m not just making this up. I did geology at ASU and a professor went into great detail about it.
I believe the coso volcanic field is likely to erupt violently in the future in a similar fashion. Most likely not a VEI 8 but probably a VEI 6-7. It will be thousands or hundreds of thousands of years in future but I see the dynamics of that region as a real threat for explosive eruptions.
Apparently you don't know Arizona! Almost the entire state has volcanic activity! Kingman on the west, on to Flagstaff San Francisco Peaks volcanic fields. Which did like Mt St Helens but it blew to the north, and sunset Creator which was still erupting when Columbus landed. Almost the entire eastern side of AZ is Volcanic. Picatcho peak between Tucson and Phoenix, south of Tucson also. Plus many many more. Then there is the Mogion Rim area. Which is a subduction zone going from Williams to New Mexico.
Maybe you can do a video on super volcanos having lithium deposits for electric vehicle batteries. Like which ones in USA, China, Africa and world have lithium.
Albuquerque, N.M. has the "Three Sisters" volcanos on the West Mesa. Capulin, N.M. in North Eastern N.M. has a volcano you can drive to the top, 2494' tall, elevation, 8,182'. (Google it) Nice drive & you can hike to the bottom (inside) or walk the rim on nice trails. Also, see 4 states from the top.
La Garita is one and there are likely others from several tens of million years back when the subduction zone was closer to present day colorado. West of colorado is all accreted landmass and some more recent extension through the great basin of Nevada, Utah, and parts of California. The pacific plate kinda forces a slow clockwise rotation in the western North American Plate. As evidence by the snake river plane and the weird locations of supervolcanoes in Eastern Oregon. Sorry about the tangent. It's hard to explain western US geology without remembering its rotating while moving.
If those super volcanoes ever erupt all at one time then Earth will be changed forever, if it survives that is, because just the super volcanoes here in this country alone could destroy this planet.
Speaker (computer?) cannot pronounce many words and is impossible to understand. He also left out Yellowstone which is one of the worlds largest super volcanoes.
The Lord’s great and terrible day is coming. But first, the seven year tribulation period. Seek Him the one who made you. He has given His word- "So I say to you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks, receives; and he who seeks, finds; and to him who knocks, it will be opened.” Luke 11:9-10
Very deceptive video. Made it appear that a volcanic eruption occurred 8 days ago. Makes me angry for people to be devious to get childish attention. Grow up
I recently stumbled upon a research paper discussing a large holocene eruption for the mount rittman volcano in antarctica and was wondering if you would be interested in doing a video about it. it was called "Evidence for a large-magnitude Holocene eruption of Mount Rittmann (Antarctica): A volcanological reconstruction using the marine tephra record"
I ‘ve driven several times between southern California back to Virginia and have seen volcanic craters in Arizona but no time to stop and investigate/enjoy. Will try to make time next time an exception. Thanks!
You pass right by two extinct volcanoes on the way to Arizona from Barstow on the 40 (and previously, the 66). Pisgah and Amboy. Amboy crater is on BLM land (in National Trails Monument) and Pisgah is technically private property, but I think Pisgah is more interesting (what's left of it since the pumice mining operation left), since the lava field (Lavic Lake) is bigger (I think the cinder cone is bigger also) and there are actually still sections of lava tube you can walk through. And then there's the Mojave Desert Lava Tubes, but that's a day trip off the freeway in the Mojave National Preserve, and at Hole in the Wall campground there's excellent climbing and hiking through volcanic ash walls (which I think would be from the Silver Creek supervolcano in the video), and more cinder cones outside of Cima off of Kelbaker Rd (also home to Kelso Dunes)
I lived in the Kingman Arizona area for a very long time I actually lived to the east of the town by about 40 miles there is a volcanic cone due south of where I'm at on silver springs road and I can show you numerous volcanic flows and that whole area including what you're talking about in this video and I've even pointed it out to many people have been with in that area. There's even a section to the south of my location and wish an entire flow of perfectly round rocks litter and entire pathway I've used those rocks to build my wall around my property
Is there an earthquake fault that caused the 1812 Madrid earthquake? And what geologic process is responsible for creating the boiling river of death? Found in the Amazon.
Has the crater in the Gulf of Mexico been related to this cause? I'm no scientist but assuming that astroid hit and made that crater it's trajectory could be the source of things present?
Tough question. The usual idea is that North America has been subducting oceanic plates at a very shallow angle, which resulted in various orogenies. Said plate(s) then snapped in places causing an rushing upwards of hotter material from the mantle. Also, the elevated parts of NA (from subducting the oceanic plates) have been trying to reach equilibrium (lower in elevation) and this has caused a great many faults through which magma can rise. The subducted oceanic plate(s) brought with them a great amount of volatiles (e.g., water and carbon dioxide) and once heated the volatiles cause both the lowering of the melting point of the material in which they are mixed, and as the melted material moves upwards the volatiles cause the explosions (see "supervolcano").
What inspired me to make this video was several drives past the magnificent roadcut highlighted in this video.
The geology all around the Kingman area is fascinating.
@GeologyHub Darn, I thought you did the video because I requested this topic a year ago. Regardless, thank you.
Can you do a video about the pumice washing up on shores in Taupo
Road cuts are so cool.
Just drove past there a few hours ago, and had also been to Oatman!
I live in Lake Havasu currently. My dad has pointed out the geology here so many times. I can’t wait to share this video with him.
You have made me realize that we probably live in a brief (geologically) calm period and volcanoes are still coming for us! 😮😬
They never go away
Never. 🌋😱
There are currently thousands of active volcanoes.
Wow! You can find peach springs tuff all the way down in Superior, AZ alongside Apache leap tuff, which you can find beautiful clear obsidian in! I didn’t know it was from a super volcano!
I was unaware of the release of this video until this evening. It's an interesting coincidence as I was just driving through Kingman four and a half hours ago as I made my way home from an event in Utah. I noticed the volcanic features in the road cut, as well as what I suspected to be a large dike in Kingman itself, and was planning to look into the feature next weekend when I had time for my geology hobby. How fortunate for me that this is the first suggested video I saw on TH-cam when I got home.
I'm from Kingman Arizona!! WOW 😳 I've been to Oatman hundreds of times!
Me too!
Little bit of feedback. The reddish orange frame - it looks really good, but when I glanced at the thumbnail my knee jerk reaction was to mistake it on the bottom for the red TH-cam stripe that means I have already viewed it. The only thing that made me double take and actually watch it was stopping to read the title and knowing I would not have forgotten that if I already saw it because it’s local (ish) to me. Then I looked closely and noticed it was framing not just on the bottom. I worry you will have viewers accidentally not watching episodes.
Love your channel. Keep up the great work. I always enjoy your content.
I had the same reaction.
I also had the same thing ❤

Anyway stay safe.I live in South Australia.No volcanic activity.
Gold and Silver have been found there, how about you ?
The Springerville Volcanic Field is supposed to be connected to this super volcano in New Mexico. I'm 13 miles from Show Low and there are lava tubes in Show Low.
This was a great video. Hard to imagine what that would have been like at the time. Glad we don’t have any eruptions like that to deal with!
The largest supervolcano and resulting Caldera is the whole San Luis valley of southern Colorado .It was so huge it accounted for the Rio Grande rift. Can you please do a video on this ?
This was the San Juan caldera
I've read that Guffey, CO sits on the rim that was a super volcano & there was a really huge eruption millions of yrs ago. Since there are so many dinosaur remains to the north & west of that area (as well as Florissant Fossil Beds National Park) we know something had to have happened.
These kinds of videos always fascinate me! What nature can do to the planet is awesome and terrifying, both!
You're not kidding, I just found out I have a supervolcano in my backyard!
Wild. I use to live in Kingman. I'm guessing the gold mine activity in Oatman exists because of this eruption too?
I was just about to search for the Silver Creek Caldera and this came up. Been looking to see where a nearby volcanic deposit came from that wasn't from the Tome hill area. Thanks.
Shows you the world changes in one day, not millions of years, but in a single day.
Great video; fascinating area.
Got relatives in Kingman, will have to look closer
Another fantastic video.
Thank you I was looking for something about this on TH-cam a few years ago and found nothing. I grew up in this area and still live here and we were all told in elementary school that we live in this volcano
Never heard of this one just Yellowstone and Long Valley! Thanks.
Question: How many supervolcanoes are there in the United States? Both active and inactive?
You got one in super volcano one in Russia and if I remember two more this is one of them. No I didn't know about this
Can you do a video on the volcanic area in Massachusetts? I know it’s pretty low with information but people say that there was a super volcano in Maine. I don’t know if there’s any way for you to do it for you on that that would be great.
I'd like to see a video of the Dotsero caldera in Colorado. I go fishing there all the time at the Colorado river. There's igneous boulders everywhere and a whole mountain of ash close to State Bridge Colorado.
ooh, could you do a video on the fault lines along the Mississippi River? i.e. the New Madrid and Baton Rouge faults?
One of the firsts again. As soon as I see the notification, I click. Greetings from spain ;)
Love me some Pyroclastic flow!
I grew near Kingman, in Lake Havasu, and you can see those stratified layers along the Colorado River nearby. Same when you drive on I-40 through Kingman where the highway cuts through rock. Even prettier along Az-95 between Parker and Lake Havasu where you can see red rock. It's the most beautiful part of the desert there, but sadly a horrible place to grow up. Residents have no self-respect and respect nature even less.
There are no extinct volcanoes. Only dormant, or sleeping, and active.😉👍❤
In northern Arizona we see the volcanic and marine history of the area. The Sacred Peaks and cinder cones being evidence of vulcanism, and to the northeast are marine fossils. It is a fascinating place to be!
I was flying from LA to El Paso and all the hills I drove by were ancient volcanos. Looking out the window of the plane I could see the cone at the top of each one.
1,800^2 km of erupted material in 10 hours or less... And just a few weeks ago i was amazed by one the Taupo eruptions due to it's rate of ~100^2 km of material in less than an hour...
I camp in area 6 miles west of Parker AZ - there is a area Full of Stromatolites - I have a 5 pound example that has over 100 layers
When you zoomed in on the highway cut, the first thing I noticed was the disruptions in the ash layers. Crustal extension faulting, or some other local activity?
I would love to here about the volcanic chain in south eastern Az from Paradot that goes along the Gila Valley All the wake to New Mexico
I'm surprised, but this planet has surprised me entirely. Thank you for mentioning that extinct volcano in Alabama I would have never known about that. Because they have taught us that if we be quiet we can win the civil War which ended 150 years ago and the south lost humiliation all around 🤦🏻♀️🤦🏻♀️😞
There’s an old volcano near Holbrook Arizona.
What makes a volcano a super volcano as compared to a regular volcano?
QUESTION: Is the Kirkland Tuff from the same eruption as that deposited around Kingman?
ECOMATERIAL Technologies is currently mining this deposit of pozzolan to enhance concrete mixes.
Viva Arizona!
Have you done a video on the taney seamounts yet?
Wow. 🌳🐾
So, this supervolcano falls within or "soon" after the big ignimbrite flare up in the Late Tertiary? That same period includes La Garita and several other supervolcanic eruptions all over what is now the American West within a geologically short period of only a few million years. Do we know anything about what deeper processes might have caused that huge burst of large eruptions?
I don't think there is an agreed upon cause however based on the crazy Eocene series from Nick Zentner there does appear to be an age progression within the Laramide and associated volcanic arcs starting from the late Paleogene into the early Miocene with the volcanism geologically coinciding with the exposure of metamorphic core complexes also within the Laramides.
The general picture I get from this is that we know these two processes occurred relatively simultaneously with a age progression along what had been a towering high continental volcanic arc under compressive strain for some reason or another began to collapse which appears to be the cause of both this extreme and increasingly siliceous volcanism and the exposure of deep metamorphic core complexes as the orogeny fell apart into Graben horst type terrain to some degree.
The tricky part is why this change happened. One camp argues the Laramides simply just became too tall/overthickened and collapsed under their own weight and we don't need any other complexity but another picture accounting for the underlying slab which ca still be observed via seismic tomography notably with evidence of tearing and or detachment suggests the detachment and or breakages within the Farallon slab probably played a big role in this picture though telling when such events in the upper mantle took place is tricky especially since the underlying geology of the west coast of North America has turned out to be far more complicated than had been expected with evidence for lots of intense geological dynamics over the course of the Mesozoic and early Cenozoic including an unknown number of arc collisions and accretion ranging from oceanic to continental with variation chemically suggesting that the original arcs have been shuffled around and broken apart over geologic time, with even evidence for sinistral motion, pulses of volcanism with arc advancements and retreats and quite probably even lateral movements in crustal blocks, not to mention Siletzia and the Yellowstone hot spot, or even the broader and generally quite complex larger Pacific front as a whole all being dynamic in ways which are hard to understand/interpret.
If I had to make a more general informed guess it probably had to do with the broader rearrangement of the Pacific plate as the collapse to the Northern extent coincided with some fairly extreme rotations and reshuffling of the position and type of fault boundaries along the Pacific around the same time as the Paleocene Eocene Thermal Maximum. This was a very chaotic time geologically what with two Large Igneous Provinces forming relatively contemporaneously along oceanic ridges (or what would become an oceanic ridge as the North Atlantic Large Igneous Province formed along failed rifts between Greenland and Eurasia which had then been attached and Siletzia/ Yakutat terranes which appear to geochemically share the same origin separated by seafloor spreading and subduction among other things as the collapse in that part of the greater Laramides was timed with the movement/detachment of part of the old Laurentian shield of North America and the accretion of Siletzia.
Regardless of how it started once it began it slowly propagated to the south through the Eocene and Miocene.
The parts in states along the American southwest notably Arizona Colorado New Mexico Utah etc. happen to be the youngest and thus best well preserved portions in terms of volcanics (the evidence for these volcanic episodes to the North are largely igneous features like dike and sill intrusions, batholiths and crystalized deep magmatic conduits (most notably Devil's Tower in Wyoming which is composed of hexagonal pillars of Phonolite a type of volcanic rock associated with stratovolcanoes most notably mount Erebus.
How that earlier volcanism relates to the later volcanism is tricky though as it propagated into the older more continental parts it definitely got more silacious in composition.
It will be fascinating to see what more comes out of the study of this extinct arc
While not technically geologic, could a video be done on what goes on in a pyroclastic flow, what actually is killing you and has anyone survived it.
Jim Scymanky and his three logger colleagues were caught in the blast of the 1980 eruption of Mt. St. Helens. All of them initially survived, but within days Scymanky's colleagues eventually succumbed to their burns and ash inhalation. Scymanky himself faced a long and painful recovery over the next year-and-a-half with many reconstructive surgeries and skin grafts.
So it's technically possible to survive depending on circumstances and luck... or lack thereof.
@@waxwinged_hound I heard somewhere the heat is so intense that most just drop dead where they stand.
Do know anything about Saddle Mountain In Tonopah, Az? Was it also a volcano? And also in Acton, in California. The reason I’m asking is because in Saddle mountain is known for it’s fire agates and Acton has also agates. Thanks
ive always wondered in the caldera collapse resulted in area over the lava chamber that allowed future eruptions/gas to vent more easily due to all the structural fractures, thus reducing the chance if a repeat super eruption. so when the empties lava chamber refills, instead of gas becoming trapped and pressurized until massive explosion, the gas is able to leak out through cracks created by caldera collapse. the gas being able to leak then results in lower severity eruptions after the first big one, until fresh uncracked crust covers the mantle hot spot via tectonic plate movement.
or does the caldera collapse happen in an environment so hot the collapsing rock is completely melted/fused into a new gastight cap?
Have you ever found film of a caldera Forming due to the overlying ground collapsing
I’m curious - when a magma chamber is drained and the overlying rock collapses downward to form a caldera, what exactly does that process look like in real time?

I wouldn’t stick around to find out. Maybe drones or space photos? 😆👍🏽
Explosive or like squeezing a pimple?? Ha
I’m so confused as to why these videos consistently forget to mention, superstition mountain as a super caldera as well. It’s one of the few largest on the planet. I’m not just making this up. I did geology at ASU and a professor went into great detail about it.
Can we please get a update about home reef volcanic island?
I believe the coso volcanic field is likely to erupt violently in the future in a similar fashion. Most likely not a VEI 8 but probably a VEI 6-7. It will be thousands or hundreds of thousands of years in future but I see the dynamics of that region as a real threat for explosive eruptions.
Do you have any specific reasons why you think Coso in particular will have a major explosive eruption?
Not on this topic. I live in Michigan. What geological phenomenon caused the Ledges Park in Grand Ledge, Michigan?
What about the Sunset Crater Volcano, Northeast of Flagstaff (1,000 years ago)??
Can you talk about how the loss of millions of tons of materials washed away do to last floods will effect yellowstone.
Apparently you don't know Arizona! Almost the entire state has volcanic activity!
Kingman on the west, on to Flagstaff San Francisco Peaks volcanic fields. Which did like Mt St Helens but it blew to the north, and sunset Creator which was still erupting when Columbus landed. Almost the entire eastern side of AZ is Volcanic. Picatcho peak between Tucson and Phoenix, south of Tucson also. Plus many many more.
Then there is the Mogion Rim area. Which is a subduction zone going from Williams to New Mexico.
Good place for New Cappadocia to be founded.
I want to know how VEI works!
Crooked River Caldera, Oregon?
Maybe you can do a video on super volcanos having lithium deposits for electric vehicle batteries. Like which ones in USA, China, Africa and world have lithium.
Albuquerque, N.M. has the "Three Sisters" volcanos on the West Mesa. Capulin, N.M. in
North Eastern N.M. has a volcano you can drive to the top, 2494' tall, elevation, 8,182'.
(Google it) Nice drive & you can hike to the bottom (inside) or walk the rim on nice trails.
Also, see 4 states from the top.
Can you do cerro guacha
11-44mph? Is that a typo?
I just dont get how you can claim that anything is millions of years old without any proof.
What about a special 200k subs video
Scientists found a possible super volcano Caldera
under the ocean floor in Alaska islands chain.
Springerville volcanic field
Please
No volcano is extinct just super doormat because the ring of fire can resurrect a volcano that people think is extinct end of story...
What ancient super volcanoes were in colorado?
La Garita is one and there are likely others from several tens of million years back when the subduction zone was closer to present day colorado. West of colorado is all accreted landmass and some more recent extension through the great basin of Nevada, Utah, and parts of California. The pacific plate kinda forces a slow clockwise rotation in the western North American Plate. As evidence by the snake river plane and the weird locations of supervolcanoes in Eastern Oregon.
Sorry about the tangent. It's hard to explain western US geology without remembering its rotating while moving.
I may have a new one
Why Denver Colorado sit in a bowl
How many of these monsters are in the continental US?
@Flysoon. 4 if you count wah Wah springs
Wah Wah is considered dormant
❤
Oregon a has Caldera.
If those super volcanoes ever erupt all at one time then Earth will be changed forever, if it survives that is, because just the super volcanoes here in this country alone could destroy this planet.
Oh no. The sing song voice. Can’t do it.
Paranoia will destroy ya.
Speaker (computer?) cannot pronounce many words and is impossible to understand. He also left out Yellowstone which is one of the worlds largest super volcanoes.
18 million years ago... Must have been caused by global warming.
Dude..change your channel name to the history channel.
Why is it that nobody can narrate anymore? Stop using AI voice please!
You know its a lie when they mention ages over ten thousand years!
The Lord’s great and terrible day is coming. But first, the seven year tribulation period. Seek Him the one who made you. He has given His word-
"So I say to you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks, receives; and he who seeks, finds; and to him who knocks, it will be opened.” Luke 11:9-10
Amen!!!
Its always doomsday to a simple cultist
Very deceptive video. Made it appear that a volcanic eruption occurred 8 days ago. Makes me angry for people to be devious to get childish attention. Grow up
Dang, youtube algorithm seems like suggesting this video to idiots 🤣
Stop calling them super volcanoes. They are not live
500 zillion years ago,,, what a crock of crap.
Reality check:their ain't no 15-20 million yrs past.there's not even 50,000 yrs past..just sayin'.....
i didn’t know Arizona has a supervolcano
Both are long extinct luckily.
I recently stumbled upon a research paper discussing a large holocene eruption for the mount rittman volcano in antarctica and was wondering if you would be interested in doing a video about it. it was called "Evidence for a large-magnitude Holocene eruption of Mount Rittmann (Antarctica): A volcanological reconstruction using the marine tephra record"
One shudders to picture pyroclastic flows a mile high.... Not a kilometre high, a MILE high....
1.6 km high. HTH
^ right, it's not like there's a huge difference between a mile and a kilometer lol
Now that is what I'm talking about. 1300 km^3 of material. Looking forward to another similar event in the future.
I ‘ve driven several times between southern California back to Virginia and have seen volcanic craters in Arizona but no time to stop and investigate/enjoy. Will try to make time next time an exception. Thanks!
Perfect! There are several locations to choose to stop. The easy choice is sunset crater.
You pass right by two extinct volcanoes on the way to Arizona from Barstow on the 40 (and previously, the 66). Pisgah and Amboy. Amboy crater is on BLM land (in National Trails Monument) and Pisgah is technically private property, but I think Pisgah is more interesting (what's left of it since the pumice mining operation left), since the lava field (Lavic Lake) is bigger (I think the cinder cone is bigger also) and there are actually still sections of lava tube you can walk through. And then there's the Mojave Desert Lava Tubes, but that's a day trip off the freeway in the Mojave National Preserve, and at Hole in the Wall campground there's excellent climbing and hiking through volcanic ash walls (which I think would be from the Silver Creek supervolcano in the video), and more cinder cones outside of Cima off of Kelbaker Rd (also home to Kelso Dunes)
I lived in the Kingman Arizona area for a very long time I actually lived to the east of the town by about 40 miles there is a volcanic cone due south of where I'm at on silver springs road and I can show you numerous volcanic flows and that whole area including what you're talking about in this video and I've even pointed it out to many people have been with in that area. There's even a section to the south of my location and wish an entire flow of perfectly round rocks litter and entire pathway I've used those rocks to build my wall around my property
Love the Willows
Is there any visible trace of the old caldera, or has time and geological events covered the majority of it?
Uh oh... I work on Silver Creek road! 😬
Thank you for the video. It’s great to learn new things about volcanoes.
Hell we have a shitload of volcanoes in Arizona that's what made Arizona so beautiful
Is there an earthquake fault that caused the 1812 Madrid earthquake? And what geologic process is responsible for creating the boiling river of death? Found in the Amazon.
Has the crater in the Gulf of Mexico been related to this cause? I'm no scientist but assuming that astroid hit and made that crater it's trajectory could be the source of things present?
The speaker speaks so fast that he cannot pronounce most words making the audio worthless for this video.
Why were there so many super volcanos back then 15-30 mya? What was the geological history for them?
Tough question. The usual idea is that North America has been subducting oceanic plates at a very shallow angle, which resulted in various orogenies. Said plate(s) then snapped in places causing an rushing upwards of hotter material from the mantle. Also, the elevated parts of NA (from subducting the oceanic plates) have been trying to reach equilibrium (lower in elevation) and this has caused a great many faults through which magma can rise.
The subducted oceanic plate(s) brought with them a great amount of volatiles (e.g., water and carbon dioxide) and once heated the volatiles cause both the lowering of the melting point of the material in which they are mixed, and as the melted material moves upwards the volatiles cause the explosions (see "supervolcano").
Sounds like no facts here. All hypothetical.
You forgot the active volcano on the island of Hawaii.
