Hydrothermal explosions can occur (quite rarely) in areas not directly linked to volcanic activity or underlying bodies of magma as proven by today’s video.

My ex-wife used to have these- not rarely- after having salsa from the local Mexican restaurant. Good salsa though 😋

Before visiting Yellowstone in 2013, I remember reading a warning that most geysers not named Old Faithful were unpredictable and could erupt forcefully at any time.

Can we have thermal thursdays where you talk about geysers, hotsprings, and anything else geo/hydrothermal related?

That is a good idea, especially since the restaurant down the street has great taco Thursdays. You know.....explosive outgassing. Oh I just kill myself

Okataina caldera gets a shout out 👍😆 I'm a kiwi, I got excited about it. Cool video 🥰 really interesting

Thank you for this video I found it very interesting.

You know i think it's funny how "the ground simply exploded" is a valid explanation here lmao

Thanks for all of your hard work man!

Are the "jalapascos" (craters) near San Antonio Jalapasco and San Miguel Ocotenco in Puebla, Mexico also similar hydrothermal explosions? They have almost no rims. I bicycled to them after my climb of Pico de Orizaba / Citlaltépetl in 1991. As a Canadian, I found them quite exotic.

So the difference of phreatic explosions vs hydrothermal explosions is phreatic has nearby magmatic intrusion as a heat source but hydrothermal is just heated by ambient crustal temperatures?

California certainly does come up with all kinds of curious ways to remake its own landscape. Not to mention our own interventions in her experiments.

Mother Nature certainly loves rearranging the furniture here in Cali. ✨

So…phreatic eruptions are all hydrothermal explosions but not all hydrothermal explosions are phreatic eruptions?

Exciting and little scary but pretty neat at the same time

Another geological history video. Thanks again Greg. 😊.

I very much enjoy your geology videos. Thanks

Thanks! I’d never heard of this place or this phenomenon. So intersting!

Thanks as always!

Thanks for sharing! 😊

Thanks.

That is an incredible event. I had no idea. Would you be so kind as to do a video on the volcanology of Alpine county, California?

Very like the features near Lassen about 120 miles SE of here. That said my Lassen memories are from 1978 so those features may be long ago faded away.

A 44 second old video? Sounds like fun

Could this happen in hot springs ark?

⚡💥🤘🏼Really Cool 🤘🏼💥⚡

Uncommon 🤔 funny. We get several per year in our NZ supervolcano zone. Pretty big one took out the supercritical 1200ft high Waimangu geyser in 1912, and left a 2 km across crater. 🤗

@@xwiick Note that Yellowstone also produces hydrothermal explosions it more has to do with the trigger mechanism whether it is considered a true phreatic eruption or a mere hydrothermal explosion. From looking up the location on the state geological map it appears to be within the zone of extension east of the main Cascades often referred to as the back arc which in this particular case based on seismic tomography also seems to correspond to where the solid upper mantle, presumably thermal, low sheer velocity discontinuity seen in seismic tomography which connects directly to the larger East Pacific Rise and Juan de Fuca ridges (as well as the snake river plain Yellowstone proper and the Rio Grande rift valley). So from this context the heat source is likely magma but just far down in the lower crust with heat infiltrating upwards through faults within the rock.

The earth is stranger than we can understand or even imagine.

It is not just the boiling point. Water has many states of matter. We usually think in terms of solid, liquid, gaseous, and plasma. Water has, at last count I am aware of 19 different states.. One of those is critical temperature and pressure. I seem to remember that it is 700F and something, and 20 atmospheres. When water crosses that point, it becomes steam. Right then. Underground heating? When it crosses that line, it explodes and then the relieved pressure outgasses all the water. The initial explosion and then hours of jet engine steam.

Non-volcanic but boiling water? What causes the water to boil?

Can these happen in any area with hot springs like the ones people use?

This is 200 miles north of the Long Valley Caldera

has this ever been recorded undersea in hydrothermal vents? Have they ever exploded before?

This is further proof that our beautiful planet is very active and will surprise us again and again. quick question what is the state of the sidoarjo mud flow

If not magmatic or radio decay where does the heat for the hot springs come from? How does it increase in temperature if not receiving heat from below? Isn't that a Marr?

Looking up the location of Lake City California on California's official state Geological map it appears to be in the Northeastern part of the state just south of southeastern Oregon the part of the state where the solid upper mantle thermal discontinuity associated with the Gouda ridge a.k.a. the southern section of the Juan de Fuca Ridge which itself can be seen to dive beneath the continent passing through the snake river plain and reaching Yellowstone before suddenly diverting due south through to the Rio Grande rift valley before diverting west zig zagging its way through the American Southwest and eventually reemerging in the Salton Trough and going underwater at the Gulf of California as the East Pacific Rise. This also appears to correspond to the part of Northern California and Oregon where the subducted slab suddenly terminates and has traditionally been considered/classified as part of the Cascadia back arc region. So if this is the correct location then the heat source is likely magma at depth intruded into the lower crust and then following paths of least resistance up through the upper crust to the surface. Now when I used Google maps I was given a different location which would put it relatively due north of Los Angeles which would suggest some connection to the plate boundary between the detaching Sierra Nevada Great Valley block and the Baja California block a.k.a. the San Andreas and the various associated faults but I am less trusting of this compared to the state geological map. Either way the heat source appears to be tectonic in origin, either associated directly with the EPR or the zones where parts of California are getting torn off the continent. So it is probably magma just too deep and indirect to be considered a true volcano(as no magma has reached the surface or upper crust).

Hahaha after winter we dodge road craters so I could imagine 😂

I've heard the argument that ice can be considered a rock and thus water considered a lava. But I'm sure that there's geology terminology that distinguishes between the two, hence why you phrased this eruption as non volcanic. This long winded comment just to ask why would this event in the video not be considered volcanic?

What's the difference between a phreatic eruption and a hydrothermal explosion. Seeing as how the source of the Heat is the same

@Dragrath1

13 күн бұрын

It seems to be trigger mechanism mainly hydrothermal explosions at Yellowstone appear to be a consequence of mineral deposition within and around supercritical hydrothermal vents building up to block off the flow enabling pressure to build up. To be fair the distinction drawing the line is somewhat arbitrary

I was in a volcanic eruption from Mount St. Helen's. Folks! Listen to this!

I would prefer that he did continue. Although I think in metric myself as I think do most scientists and most Europeans, there are clearly still a lot of US viewers who still think in Imperial, so why not keep everyone happy by using both? But ultimately Tim's choice of course.

Ummmmm blowing mud

Superheated water has a critical maximum temperature of 374°c. That is of course under pressure, which is what the conditions are like deep in the crust. This is how you are able to have hydrothermal deposits when your school text book says that water boils and turns to steam at 100°. But have you ever tried to liquify quartz by boiling it. That will not happen. But that's only one part of the story of what goes on deep in the crust with water. I'm not paid to give geology lectures so I'm out.
