One of my favorite "field trips" as a kid was to Jordan Craters. Went twice with the school and then two more times on my dirt bike. (Lived in "nearby" Caldwell ID). I've always kinda hoped it would erupt again - my "local" volcano.
My wife and I visited the crater and lava field you described a few years ago. It fascinated us so much that it made the drive on rustic road in the middle of nowhere well worth it. Some of the lava looks as if it cooled just recently. Some places are dangerous where I felt that one could fall into deep pits. The edge of the flows make a stark contrast between grazing land and a sudden edge of a wall of solid lava.
Thanks as always! The Jordan Craters' eruption, specifically the cone collapse, reminds me of when Fagradalsfjall 's 2023 eruption spatter cone also collapse, sending a huge flow of lava towards the west!
It is such a spectacular environment, comprised of a seemingly endless landscape of pahoehoe once you've hiked in a ways. You have to be careful of areas where the lava tubes are so thin at their apex that they cannot support your weight. In some places the ceilings have collapsed and you can see the grisly consequence of falling to the bottom which consists of sharp points of broken lava sticking up in all directions.
Question: have you ever covered the volcano/lava fields feature that sits between Medina and Mecca in Saudi Arabia? Seems it's overdue an eruption and the last one (13th century) stopped just short of wiping out Medina. I have read that small magmatic tremors have been on the increase since 2009 - maybe this is worth a video?
One of these days a dormant, little-known volcanic system this channel has covered (which the average person knows nothing about) will build up to an eruption.
I'm seriously skeptical on the slab based theory as it doesn't appear to match up with the results from seismic tomography which are able to clearly reveal areas of mantle upwelling and sinking subducting slabs which appear to be the mantle's downwelling component. Personally the area appears to be where the thermal discontinuity in the upper mantle seen by seismic tomography as a slow sheer velocity anomaly passes through Oregon alongside the abrupt termination of the Juan de Fuca plate an anomaly which can be traced into Idaho as the snake river plain or into northern California where it connects directly to the surface expression of this feature known as the Juan de Fuca Ridge. Notably the Yellowstone hotspot also falls along this line and there is clear data from the igneous petrology of Siletzia and Yakutat that the responsible Oceanic plateau was a former ridge line hotspot like Iceland and we can trace the boundary of this deep mantle discontinuity through the edge of the Colorado plateau the Rio Grande rift valley and out through New Mexico and Arizona where it reconnects with its main surface expression as the East Pacific Rise. Suspiciously this boundary lines up nearly perfectly with the zone of recent inter-plate volcanism in North America and the overall boundary of the Basin and Range Province as a whole. Coincidence? I think not especially since the clockwise rotation begins when North America hit and started to accrete Siletzia with a sequence of progressive explosive volcanism and exposed metamorphic core complexes over time beginning in the north and moving south over time like it lines up with North America getting pulled over and into this underlying oceanic ridge and hotspot upper mantle configuration. These ridge like upwelling discontinuities in the upper mantle where they exist without an overlying continent notably appear to correspond to major oceanic ridges in general suggesting that there is likely a causal relationship and research has even shown that hotspots over time appear to migrate towards the nearest ocean ridge systems feeding their heat flux into the ridgeline system though some major hotspots appear to be able to persist longer perhaps because they are more vigorous and active having had associated major flood basalt eruptions in the last few hundred million years?
How can y'all get the timeline of events of when volcanoes erupted hundreds to thousands of years ago? It just seems that a lot of those details are highly specific for something that happened so long ago. Could you possibly do a video about the process of getting data from volcanoes?
Yeah their is some work very critical of these models as unphysical particularly in the Cascades as we can tell via seismic tomography that there is no subducting slab there (or rather this is near the edge of the slab). Personally the area appears to be where the thermal discontinuity in the upper mantle seen by seismic tomography as a slow sheer velocity anomaly passes through Oregon alongside the abrupt termination of the Juan de Fuca plate an anomaly which can be traced into Idaho as the snake river plain or into northern California where it connects directly to the surface expression of this feature known as the Juan de Fuca Ridge.

The fit is so perfect that I don't see why it hasn't been immediately recognized as the best fit model for western USA geology. Yes you can't just pretend mid ocean ridges just magically go away when a continent passes over them just like a section of the ocean doesn't stop existing when a ship passes through. Even the extension in British Columbia fits perfectly with the off shore regions of Explorer ridge and we seen the same structures in seismic tomography beneath the Mid Atlantic Ridge and every other major active spreading center extending deep down into the Mantle to encompass the entire upper mantle if not deeper.
@@Dragrath1That's an impressive comment, virtually an alternative video in its own right. As a Brit I don't know western North America well enough to follow all of your arguments without an inordinate amount of work (and I'm here for fun not work), but what I do understand makes a lot of sense to me. And much as I admire GH and his work, the channel is actually better for well informed and calmly expressed alternative views like yours - because that is how science advances, by constructive debate and discussion between alternative interpretations as well as by new hard data.
That is part of every Sunday's updates(occasionally if a big eruption happens it might be delayed a day or two at most but otherwise it is always Sunday) . Check the episode from yesterday it had that information.
Given the recent events in Iceland, I wonder if the people living near the Jordan Craters, and other volcanic fields like it, are starting to feel somewhat uneasy? After all, the last time the Reykjanes peninsula in Iceland saw the level of activity it's experienced in the last few years, was 800 or so years ago. This isn't to say the the Jordan Craters are going to 'wake up' in the coming months, but it does beg the question: what is the eruptive history of the field? And did anyone who moved into the town know the geological history of their new home? Did the builders? And if they did, did they stop and consider that the area might still be active, at least technically? I think most people are aware that people gravitate to explosively erupting volcanoes because the soil is so fertile. Most of these volcanoes erupt sporadically so the risks of living there is outweighed by the rewards in terms of crop production and so on. For those volcanoes like Merapi, which erupt frequently, the inhabitants around it know to leave whilst it is erupting, and come back when all has fallen silent again, and hope the activity hasn't destroyed everything that got left behind. For effusive volcanoes like those of Hawaii, there are different issues. With much of the new real estate built on old lava flows, the realtors must rely on the human penchant for thinking nothing bad will happen in their lifetime. This might well be true, but those people who bought homes and plots on the Leilani Estates prior to 2018 got a massive reality check when Kilauea LERZ swamped the area with lava. Admittedly my views of Iceland and Hawaii are vastly different, when both may have the same issue: they need to build new homes and communities but suitable land is scarce. It's just that, right or wrong, because Hawaii is a 'tropical paradise', it always feels to me that people are being encouraged to seek a little luxury buying houses away from the cities. Iceland, on the other hand, relies on fishing for part of its food supply, and Grindavik was built where it is because the place as a good spot for a harbour. What makes the recent events there all the more saddening is that a good percentage of the population moved there from Heimay, another town partially destroyed by volcanism in 1972. Perhaps its time those people who decide that new towns and so on are needed, and where they should be put, to change the way they make those decisions. I believe town planners look at flood risks in the initial phases: perhaps they need to look at the geography with an eye to potential volcanic activity at the same time!
A lot majority of does. Videos covering current eruptions often have the words update, this week in volcano news, and the name of said volcano erupts, etc.
I know what you mean - by calling it 'The' active volcano that seems to imply that it is the only one. But that is how GH always titles his videos. Tim - perhaps a slight change in your titling to 'An' active volcano would be more accurate? But let's not lose sleep over it one way or the other!

I saw that! It looked so epic! But so dangerous at the same time.
Wow, I've lived in Central Oregon since 2007 and I've never heard of these features. Guess I'll make a trip east this summer
Thanks for all of your hard work man!
Great video. I didn't know about this. Thank you GH

Oregon's version of Craters of the Moon in Idaho?
Vice versa. 😃 Jk!
This would be awesome.
It would be really nice if you insert the occasional "we know this because" into your descriptions of event sequences.
Thanks.

By measuring ratios of isotopes in crystals that precipitated out of the lava.
There's isn't a consensus about that slab steepening.

Any gold found in the area? Id detect it
How come he’s not telling us how many volcanoes are active lately each week

I wish it was easier to tell from the titles what is current and what is more educational

You should do a video on the volcano in Portland Oregon
He has done that already. I think this is called the boring volcano field if I remember correctly. Yes, it actually is called like that.
Specifically, Mt Tabor. A lovely park!

There's more than one active volcano in Oregon.
