Thanks for the Geology Hub information. I suggest making a video about the extinct volcano in the Brazilian Amazon, considered the oldest volcano in the world.
The oldest volcanoes are the flood basalts that made entire landscapes with lava so low in silicate that they barely made a hill but stretched outwards for tens and hundreds of miles.
Looking it up its not the oldest volcano in the world rather it is the oldest preserved volcanic *explosive caldera complex* in the world dating back to 1.88 Ga. In this case the magma involved in this volcanism was rhyolite and rhyodacite so extremely siliceous material. This occurred in the context of the ancient super continent Nuna/Columbia during the Paleoproterozoic. There was volcanism on Earth for billions of years before this its just little material that old survived to the present day.
You must be talking about some basalt exposures (maybe near fissure locations?) from the Central Atlantic magmatic province, which erupted a couple hundred million years ago, over a period of about 600k years.
Excellent video! Geology Hub, may I suggest you post a video analyzing the paper about the stopping inner core of Earth and it's possible change in rotation direction? Thanks!
Question; locally there's Green Lakes state park, NY. They are both extremely deep, 1 round lake looks like a blow vent, I've free dived as deep as I dared to over the years, and saw the walls are vertical for at least 50 feet down into the blackness. Green lake also has nearly vertical walls. The area has igneous rock fragments all over the park. It is also known there's a submarine passage between the two lakes at some depth verified by sonar. My question is; are they extinct explosive eruption remnants? Similar to the famous diamond mine in South Africa?
If you are looking for volcanism, I believe the Palisades on the Jersey side of the Hudson would interest you. Put a different way, what as the Mid Atlantic states and Scotland used to be connected to each other.
Diamonds: how made, why different colors, why some are found on top of the ground, sizes, what makes these rocks so valuable, location (blue diamond NV) etc. Thank you, I love your channel.
its a place you should visit, the caldera is 80km wide with high herb natural park aso-kuju national park and you have pine on 300m cliff on caldera border, the bottom is full of crops field ; its very pretty, you can do horse, theres onsen hub not far too, and kyushu food is very good...kyushu is a very good spot for holiday for volcanoes fan hikers and food enjoyers. , dont miss yakushima sakurajima kirishima, nagazaki unzen, fukuoka etc... note that for aso, the crater is often barred from visit, since its smoking all the time
After Hunga-Tonga-Hunga-Ha'apai I think it's time to stop using Mt. St. Helens as the comparative scale. A lot of people watching this were not even alive when it happened. I was only 4 years old when it happened so other than the footage and documentaries about it, I can't even truly compare it myself.
Funny thing is that he's not the only one. I think people here in the US use Mount St Helens because it erupted here. When Hunga Tonga erupted, that's when I heard comparisons to Pinatubo or Krakatoa. It's an interesting frame of reference.
Does steam take up more space than water or is it atmospheric pressure coming into play where the water is trying to dillude itself into the mixture of air? Or something like that.. I'm not entirely sure how to word what I'm trying to convey
its sort of like this . . . .when a liquid like water expands from a liquid into a vapor, its about a 1000 fold increase in volume at sea level. The pressure of the overburden can contain any expansion by water. Keep in mind that a lot sulphur exists in volcano rocks and can mix with water to become sulfuric acid, which will weaken rocks. Certain metamorphic minerals are created many miles below the surface of the earth in the presence of water.
I think it would be informative to contrast the sort of unrest we're seeing now, with what geologists would expect preceding a VEI-7 eruption at a complex like this one. In the latter case, I'm assuming we would have at least months of very notable uplift, gases escaping from all over the caldera complex (maybe no?), and a much longer and more intense period of seismic activity.
@@marshallpeters1437 - I'm thinking of warning periods preceding a mid-to-large VEI-7, in a system like the Aso caldera. ... one would like to think, at least, that a little puff that doesn't make it out of the caldera, and a 700 km3 VEI-7, would be distinguishable ahead of time.
Well let's hope it keeps letting off pressure and keeping the magma chamber depressurized where it won't seal itself up and fill the whole chamber to the point it super erupts! Smaller eruptions are probably a good thing.
I am interested to learn about special rock types also since as a amateur rock hound I haven't had a chance to read the library of books on all the fantastic rocks and crystals out there. Also special exposed colorful rock formations are of great interest.
@@treck87 lolz well you are looking for special rock types. If I said rubies in Greenland I think that would be hardly helpful. Since you don't ant advice, I will suggest you start with your local geological survey, learn how to map a geology and read topography, and get yourself some USGS or similar maps.
Hi from UK OT but I heard something abt rocket launch to investigate mining mineral resources on asteroids? Presumably a niche knowledge mixing resource development and developing public interest in progress. Might be colab sponsorship from venture capital seeking?? Just an odd suggest, I am sorry did pay attention to more but was very recent in the last month.
Venture capital??? No, that will be funded entirely by major investors because the cost of development is going to be in the hundreds of billions and that just gets you the spacecraft that can reach the asteroid and mine it. It does not include the cost of launching it, nor does it include the cost of return, maintenance, and crew.
What would be very nice, is if you stopped using the same footage and photos, so often, and giving the same word for word descriptions day after day gets a bit wearing, some more variety would help greatly, other than that, excellent information.

@@Vesuviusisking Oh yeah, I am 1/4 Italian but won't be moving to my ancestor's homeland either. I think I was 3 when I saw the wizard of oz, asked what a tornado was, and was explained that certain areas have environmental hazards like tornadoes or hurricanes or earthquakes and I was horrified. I decided never to live in a tornado zone (at the age of 3) because why would you wanna live somewhere where at any time a random storm could destroy all your stuff or kill you or your family, pets, etc when there's other places available to live? I now live in California near an Earthquake fault but far enough away that none of the earthquakes have, so far, destroyed my home or any prized posessions, and just outside of the tsunami zone for anything but a mega-tsunami that defies all zones. I have two earthquake policies, keep all my electronics in boxes covered with blankets, have trained my cats to run to me when I make a certain sound, and have some giant cages to evacuate all my animals. In the last few months repeated earthquakes have destroyed like maybe a few hundred houses in my county, and I'm ready for it if it hits me, we will get out with my cats, my electronics, and my family, and hopefully my most valuable houseplants.
So the largest known eruptions on the valcano scale go up to 8 and are what is called super volcanoes. The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning the measured deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles). Sorry, but this isn't a super valcano if it only has a scale of 7. If it went off that much it would be devastating. But volcanic eruptions get much bigger..
@@Vesuviusisking The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning that at one point in time it erupted more than 1,000 cubic kilometers (240 cubic miles) of material. From the USGS. Same from the BBC. Wikipedia says 1,000 as well. So did the rest of the first page when I googled define supervolcano. Also, 500 km of material erupted makes no sense for a definition. VE7 is from 100-1,000 km erupted material. So some volcanos classed as a 7 are supervolcanos but others aren't?
@@Vesuviusisking Their are literal definitions for volcano eruptions. VEI 7 goes up to 1,000 km. VEI 8 is anything over 1,000 km and is called a super volcano. Just because a lot of people would die due to living in the caldera doesn't make it a super volcano.
Is Epi like Loihi, a little volcano off of the main ones? Also, Vanuatu is quite geologically active, but I can't remember if they're on a plate boundary or not.
Its kinetic energy or alternatively as @Mr Peabody mentioned Inertia remember we are dealing with an explosion here the relative difference in momentum from the expanding shock front is high thus it can't cool or slow down as there is even more pressure coming from behind. Its the same reason a Tsunami continues to surge forwards even after the displacement event, you have a propagating wave carrying high temperature pyroclastic material in suspension. Remember that temperature is the average kinetic energy of a substance and kinetic energy is conserved and these pyroclastic flows are in many hundreds to thousands of degrees hotter than the surrounding air and at much higher densities you can't compare this to a puny chemical explosion.
Pyroclastic flows move at incredible speeds and kick up a cushion of air that appears to reduce friction and allows the flow to travel longer distances.
Neither Aso nor Sakurajima qualifies as a "Super" volcano! To be classified as such a volcano has to have produced at least ONE eruption that ejected a minimum of 1000 cubic kilometers worth of material and neither Aso nor Sakurajima has ever risen to that level!
Some volcanoes producing high end vei 7 eruption of above 500km³ ejection of tephra too are called supervolcanoes because of how deadly the effect can be for Earth.
I'm glad you threw in that little statement at the end about simply not knowing anything for sure... There have been no humans in recorded history that have witnessed a super eruption, so we really don't know what kind of activity would proceed such an event. I'm not being a doom sayer, but it's wise to keep our eyes open and not make any broad sweeping proclamations concerning this type of volcano. Cheers and good job. A suggestion. Follow the lead of another good science presenter that I watch regularly. Record yourself at a news desk of sorts with imagery and explanatory graphics (maps of known subsurface features, lava chambers, etc.) in the background. Make your presentations a little longer too with more emphasis on in depth reporting of recent papers published in the science journals. I'm sure the audience would enjoy hearing about this kind of thing, and your personal evaluations as well.
@@Vesuviusisking well question is, ho many super volcanos does the Earth have. Earth has accumulated a lot over the past 4 billion years, most of which are no longer active.
