Milbanke Sound is a volcano which is often forgot about in British Columbia. A similarly forgotten but presumably active regional volcano is Crow Lagoon, which is a maar complex. Do you think either of these features have erupted in the Holocene? It is up for debate in both cases.
Is it hard to find volcanos in Canada because of all the ponds/lakes and the like caused by permafrost messing with ground? I'm assuming that is why it looks like a bunch of pot holes all around canada?
What are the odds that they are connected to the subduction of the Juan de Fuca plate? The transform point from subduction to strike-slip between the Pacific, Juan de Fuca and North American plates is just to the south.
Shout out to all those geologists who must have visited, surveyed, sampled and analysed all these volcanoes, providing the information which allows GH to create such an explanation of the area's history as is given here.
TIL that Wells Grey-Clearwater is a volcanic field! I hiked and canoed around that park all these years and did not once know that it was an active volcanic zone! Very neat!
I live in Kamloops. Knew Helmeken Falls was volcanic in origin but didn't realize it was a separate system from the Kamloops Eocene eruptions. Colour me surprised when I realized it was.
I'm a short drive away from Flour Mill volcano 100 Mile House BC, impressive thick lava flow. I'm not sure, but I believe it's connected to Kostal cone volcano as well, they slightly line up, & not far apart from one another as the crow flies. I've been attempting to find hot springs via google earth which one would think there would be springs connected to the system.
Banff Upper Hot Springs! Near Banff Springs Hotel (Fairmont Banff Springs now), and other hot/thermal springs in the system. It's Alberta but near the BC border. Edit: Oops, not connected to the BC volcanoes, as far as I can tell, and not related to any Holocene (or any) volcanoes, although the recharge is possibly 10-100km away, and a deep (~3km) phreatic route (thus the water coming to surface could be thousands of years old (!). It has bacterial contributions to the water's high sulfur content, rather than a (totally) magmatic source, as I incorrectly assumed. What an interesting deep dive! I knew nothing about hydrothermal systems! Banff National Park is glorious, some great memories from there and many sights. The only thing I could find on the geology of this cave/hot spring system was this paper, where I sourced the data posted above (hope I read it right, it was deep!): Yonge and Lowe: www.researchgate.net/publication/320553179_Hydrogeology_of_the_Banff_Hot_Springs_Banff_National_Park_Canada_A_karst_perspective
Local long time loggers in your area often know where unmapped hot springs are located. BC has lots of really good hotsprings not known to tech.: mainly along the inner coast range from Meagre Creek (Pemberton) along the hot side o;f the range all the way to Harrison. But you need a mule to get to some of them!!
I would be really interested to see a video about the recent earthquake activity in South Carolina, USA. It isn't volcanic, but there's been over 30 earthquakes in the state this year so far. Curious as to what's going on?
I live 5 minutes from Columbia this is a seismic zone which is similar to volcanoes that go hundreds of years of not erupting and then all of a sudden it gets active again and starts erupting this is what’s happening here in my opinion our seismic zone is finally getting active again with all of these earthquakes.
There is a huge risk area off the coast of South Carolina and along the coast. Look up high risk areas of earthquakes in the US and you can see for yourself.
I discovered in some old 3D stereo aerial photos at my state land mapping office - evidence of a chain of ancient volcanoes in my area. They form a line over maybe 50km. The location includes Greensborough, In state of Victoria, Australia. I would love you to investigate this chain, which suggests movement of the continent over a hot spot.
Mate haven’t u been paying attention to the earthquakes… the volcanic region is waking up with the plate moving, the plate is splitting… eastern Australia’s ocean is filling up aka the basin..
Is it possible that the subducting Explorer (Farallon) Plate contributes to the more recent eruptions at Milbanke, since if its a hot spot it shouldn't be erupting concurrently at both west and east extremities of the hot spot track.
Frankly I don't think anyone knows why the Charlestown seismic zone the New Madrid seismic zone or even the Eastern Mid-Atlantic Seismic zone to the North of the Charlestown seismic zone exist so any video on the cause of that would largely be speculative as to how these old faults are getting reactivated.
The Nazko Cone is a long way east sitting in Central BC. It seems odd the two are connected to the same hot spot. Can you provide more information on that? Thank you.
I would really like to see a good update on Sao Jorge; and some postulations as to what is or is not currently happening there. My view is we are seeing the early stages of a magmatic intrusion and formation of a upper magma reservoir similar to what we see at La Palma. Although this process is likely in the early stages of development there is continuing signs of activity although at much lower levels than the initial event. However I don't think that this is necessarily a good sign as the activity has been consistent and I believe this on going low level activity represents low level magma injection and slow expansion of the upper reservoir. I would suspect that there is a much larger well established reservoir deeper down that supplies this process. As for the chances of an eruption occurring; it may still take several years before this intrusion could obtain the ability to reach the surface. I also think it is equally likely that seismicity could diminish and the magma simply remains stagnant, stalls and never creates an eruption. Overall I think what needs to be seen is if there is additional larger scale precursor events to really know for sure that an eruption is of a strong possibility.
GeologyHub, the Calbuco Volcano is located in Chile in the Los Lagos Region. Here’s a video of the April 22, 2015 eruption:th-cam.com/video/-C9jnRMIr5k/w-d-xo.html Definite pyroclastic flows and ash fall from the eruption in the clip.
I was under the impression most of the northern Pacific coast was made up of an accreted archipelago that was being scraped from an ancient, nearly gone by now, oceanic plate, onto the less dense, continental, North American Plate. The notion that these volcanoes are a product of a hot spot is surprising to me.
There is a bit of a tendency for hot spot to be tossed around quite frequently whenever there is volcanism we don't fully understand so the term is sometimes used for quite different kinds of volcanic features which appear to have different origins. In particular there are at least two distinct types of hot spots known the conventional hot spots the thermally buoyant mantle plumes appear to rise up from the core mantle boundary and thus are fairly disconnected from the plate tectonics however there are other hot spots fueled by compositionally buoyant plumes of material fed by subducted crust down within the upper mantle. This latter type of plume is much more complex dynamically as they can't be decoupled from the underlying processes. An additional complication is that crustal thinning on its own can apparently induce volcanism in a number of different ways which are not yet well understood either. There is also sheering/torsional volcanism which can occur both on its own or in association with mantle plumes which makes decoupling what is going on even harder. For example the Canary island mantle plume based on seismic tomography appears to be rising from an inclined angle from beneath Africa (so closer to 45 degrees than the usual perpendicular picture seen with the Hawaiian mantle plume, the islands themselves appear to be along crustal weakpoints due to the high transpressional dynamics of Africa and the eastern Atlantic. www.researchgate.net/publication/282434452_Imaging_Canary_Island_hotspot_material_beneath_the_lithosphere_of_Morocco_and_southern_Spain www.nature.com/articles/srep02107 Hot spot and or slab rollback are terms which have been used to lump many of these more enigmatic types of volcanism together which has lead to a number of geologists wanting to abandon the terms all together with calls to action for new models which better incorporate newer data and modes of evidence such as seismic tomography to build new geological pictures. I recommend checking out Nick Zentner's crazy Eocene livestream series from late last year to early this year as the interviews with practicing geologists gave some great insights into new work and the trajectory of modern geology research. In essence it looks like there is a newer model of plate tectonics where plates are composed of both the crust and upper mantle rather than just the crust and continents are more of buoyant silicate glaciers embedded within these basaltic oceanic plates. Also the lower mantle is connected to this system too in some degree at least with subducted slab walls/curtains Large Low Sheer Velocity Provinces and thermal mantle plumes serving as means to couple the core mantle boundary with the plates.
@@Dragrath1 wow! Thanks! This is super informative and not at all what I would have expected in a YT comment section, but am super grateful you did. I appreciate this!
As a fellow Arizonan, I'd love for you to cover the volcanic origins of the Superstition Mountain range, and some of our more recent volcanic fields: Springerville, San Carlos, San Bernardino, & Sentinel Volcanic Field.

How do you even do this
And map the volcano

Can you make a video about Bromo pls

Of course being Canadian volcanoes they locate well away from population centers and don't erupt in modern history as not to inconvenience anyone.
So they're polite volcanos 😀
@@LadyAnuB Of course ☺
My brother lives in Ocean Falls west of Bella Bella and southwest of the volcanoes. Never knew this hot spot was there but makes complete sense.
TIL that Wells Grey-Clearwater is a volcanic field! I hiked and canoed around that park all these years and did not once know that it was an active volcanic zone! Very neat!
I live in Kamloops. Knew Helmeken Falls was volcanic in origin but didn't realize it was a separate system from the Kamloops Eocene eruptions. Colour me surprised when I realized it was.
Its a pretty cool region of BC to experience, we own a cabin within the volcanic field itself.
I think it's just fabulous that you have video of eruptions a million or two years ago. Most resourceful.
Man, the amount of information and number of posts you put out is impressive, good stuff
So awesome!!! I didn’t know anything about this and lived in West Vancouver for a year 🌋 👀
I live in BC, I didn’t know we had so many volcanoes!
Thank you very much, I enjoy learning about the Canadian volcanoes 👍👍

They are relatively shallow quakes... not fracking so what is happening in SC ?
