I do enjoy your interpretations of the geology and vulcanism happening in little known regions. Seems like every other science communicator covers the well-known, popular formations to death.
To admit to be clueless in any science is refreshing to hear. So many opinions that become fact is rather comical when "science" is suppose to be based on (emotionless) facts. Hats off to you sir!
If they erupt again, let's hope it's during the coolest part of winter so that the dogsleds can still run, or during the warmest part of summer so that shipping can still happen. The Seward Peninsula no longer has railroads leading to it, and it's never been connected to the highway system. They rely on bush pilots for most of their supplies.
Im wondering if the changing sea levels could "flex" the land in that region especially. 400 feet of water being taken off then added back to a region- along with the nearby region simultaneously recieving a truck load of ice weight might account for what comes into llay here.
Some other fun ones I'd like to see you cover are some anomalous volcanics in southwest Kerguelen (which are probably just really really late activity from the Kerguelen LIP but its weird that it held on for so long), Rotuma island which very clearly has well preserved volcanic features in a very high erosion environment yet isn't even listed anywhere as a volcano, Yamsay Mountain which reminds me a lot of a pre caldera Newberry and may not be extinct but isn't listed anywhere, and Toroeng Prong in Vietnam which doesn't even have the location marked correctly (does this thing even exist???). Its kind of amazing how much we don't know about these rather obvious features on our planet. It wouldn't surprise me if deep in geologically active jungle like in New Guinea there are volcanoes that aren't even discovered yet.
Thanks for another interesting video. Would you please consider doing a video about post-glacial rebound (also called isostatic rebound or crustal rebound)? If you could go into what it is, and possibly what your personal opinions are on whether or not climate change will cause a rapid increase in this phenomenon. I read about this on the internet literally 25 years ago, and that person was warning the rapid rebound of the crust as glaciers retreat would cause increased seismic activity and tectonic movement. Obviously I can't link that page, and the research I've found on it seemed thin. What do you think? I live in the PNW so I have a fair amount of anxiety about earthquakes as it is... Thank you!
technicly there are a few spots that lack documentation from the ground all together . . but that's often because how inaccesable these places are . . .
That is a good question one which I have wondered for years, based on what I can find believe it is the degree of explosiveness whether due to gas content and or viscosity of magma cinder cones tend to have taller lava fountains that classify as strombolian eruptive activity, sometimes these systems can even produce minor pyroclastic flows and in at least one case the Michoacán-Guanajuato volcanic field during its more explosive later stages produced a sub Plinian eruption during the stage it was erupting andesite. Spatter cones are almost always purely effusive and if they continue for years can even build up into shield volcanoes while cinder cones tend to be a bit more explosive and on their higher end of explosiveness they can produce pyroclastic activity. The later extreme seems to typically be seen in larger volcanic complexes which have produced stratovolcanoes either currently or at some point in the past and thus is derived from more viscous magmas with the sustained strombolian style explosiveness keeping them from becoming a lava dome instead. I should note that for monogenic vents there seems to be a spectrum cinder cones are kind of intermediate in terms of explosiveness and viscosity basalt to andesite rich in gases. What causes a volcano to form a particular kind of volcanic vent is something I would like to understand more about.
Ive got a new one that keeps popping up on my feed: a recently discovered crater in Australia. Could you cover it? This is pulled from one of the new articles that popped up: The Massive Australian Precambrian-Cambrian Impact Structure (MAPCIS) is a newly identified complex crater in Australia, spanning approximately 600 km (370 miles) in diameter. The impact occurred around 545 million years ago, at the end of the Ediacaran period
In the late 70s I assisted 2 geologists who came to St. Michael in the winter to core drill one of the mar r craters on the island. The pollen data at 56ft (the deepest we could go).....went back about 50k years. They found pine tree pollen! That would mean it was much warmer there at that time than now..........
Its possibly related but this region extends much further back than a typical back arc perhaps it is something like what is happening with the stagnant Pacific slab beneath the Amur plate? The wide sweep seems to suggest this could be related to deep hydrous melting in the upper mantle.

i don't think anybody should pretend to know why 99 percent of vulcanoes exist. If you observe vulcano being created then ok you may know how it happens. But otherwise it is just gueses.

There is so much that we don't know about our planet
chemical heat, gravitational wave compression, and just plain density differences causing blobs to float up.

Indeed.
Just want to thank you for your work - I've been ill for some time and always a pleasure when a new video drops. Keep Well
And get well yourself, @simplybelter 🤗
Love Geology Hub!
Can't believe i was first! Love ya Geology Hub!
I am glad you enjoyed this video (and truly were its first viewer)!

Thanks for all the hard work on these videos!
He definitely earns his salt.
@@russell3380Or should that be basalt?
@@davidcranstone9044 Ha ha ha, Indeed it should, excellent point.

Thanks as always, Geology Hub!
What hppened to the Calbuco video? I was watching and it went away.
That was weird.
I accidentally uploaded it too early. Was meant to be published on a later date, so I have once again pushed back its release date.
@@GeologyHub uh oh! No worries. I'm looking forward to seeing the rest of it.

Well presented, sir!

What is the difference between cinder and spatter cones?
Google it

OK, PhD students looking for a thesis project, take note!
Just another spectacular video from you❤ thx for what you do
Would love to hear your take on the new campi flegrei articals
That... that crater is massive and the volcanoes are just sitting in it
I flew over these a few weeks ago.

GH should be reported to the FBI for his abuse of the English language…
…and I wouldn’t want it any other way!

I am not an expert but those craters in the thumbnail photo look like impact structures more than volcanos to me. Strange looking.
Could the existence of this be due to an asteroid strike on the other side of the planet?
we have not explore every inch of landmass on our planet!!!!!!!!!!!!!!!!
My comment has no value to the reader.
It's safe to say they are pretty darn old...
I want to go there
Fascinating
GEOLOGIC HOTSPOT... The HURRIER I GO, THE BEHINDER I GET...
Please profile mt. Churchill in alaska
Thanks
Meh.

Can this province be related to a some sort of back-arc volcanism?
Its possibly related but this region extends much further back than a typical back arc perhaps it is something like what is happening with the stagnant Pacific slab beneath the Amur plate? The wide sweep seems to suggest this could be related to deep hydrous melting in the upper mantle.
