It left an impression . I went several more times as one of my sisters married and moved near there a decade later. Last there in 1999. It's an amazing place to say the least.

[@ElPalcoTigreHermano]

yeah he explains the dynamic of pressurizing the inner layers of the earth but he doesn't explain how that water went into steam so fast that it caused the explosion, it means most likely that magma reached an aquifer

[@usgs]

@@ElPalcoTigreHermano If magma reached an aquifer, there would be a ton of seismicity, ground deformation, gas emissions, etc. Magma could not get that shallow without causing changes that would be obvious and all over the place. But water can go to steam with just changes in pressure. Superheated water -- above boiling at atmospheric pressure -- can exist when the system is under pressure. Suddenly release that pressure -- for example, a new conduit opens up -- and the superheated water instantly converts to steam. That's what happened here. A similar (although smaller and unwitnessed) event occurred in Norris Geyser Basin on April 15 of this year.

[@ElPalcoTigreHermano]

@@usgs I would look into the seismic reports because increased seismic activity even if low intensity can cause new conduits to open... also, into the CO2 and SO2 levels in the water from that particular and specific area, since magma releases those gases which could got into the aquifer, which could led to overpressurization. I think we witnessed ground deformation so there is that. also I think the 1989 explosion at Norris Geyser Basin happened because of magma. but I am just an amateur I do recognize that.

[@shaynejenkins446]

​@@ElPalcoTigreHermano Do some more research. You don't got it yet.

[@Smedley1947]

@alainaaugust1932 I spent a good portion of my day yesterday refuting all of the hysterical conspiracy theorist claims that this was proof that Yellowstone was about to blow. I took great pains to explain the difference between volcanic activity and hydrothermal activity. I doubt that I convinced any of those people because they wouldn't be conspiracy theorists in the first place if they thought scientifically and rationally. By the time I was 14 I understood the difference between volcanic activity and hydrothermal events mostly because I am scientific by Nature and because I had a sister who lived near Yellowstone and I did a lot of studying of information available in the visitor centers there some 50 years ago. I'm sure as I scroll down there will be the usual conspiracy theorists. Yesterday one of them said they should fire the geologist that said it was not volcanic activity, because the conspiracy theorist "knew better". I'm thinking of writing a grant proposal to study why there are so many Dunning Kruger 'thinkers' alive at this point in time.

So many people got hung up on this not being related to volcanic activity for some reason... It's like it's not even common knowledge anymore that you need more than just a single event like this before you should start to fear an eruption.

[@Sailor376also]

There are two consideration of how the explosion occurred. First there is a super critical boiling point of water. 705F at 3200 psi. There is liquid water as high as 704F AND under a pressure of 3200psi, however,, cross the line at 705 and liquid water cannot be contained, no matter what, It turns into super heated steam, and expands catastrophically. It IS possible this is the source of the explosion. It is likely that this is what created the 1.5 mile crater in Yellowstone Lake. The second possible is like a shaken soda, or champagne,, once the pressure finds an outlet, the water at less than the super critical threshold, simply turns to steam. This is what powers the geysers.

[@michaelbballard]

Ridiculous to say geothermal events like this or a geyser aren't volcanic. It's literally a Hydrovolcanic Eruption lol either it's somebody's attempt to reduce potential alarm or just ignorant public relations. Yes volcanic and seismic activity around the world is increasing. If the thermal energy from volcanic activity didn't heat the water, then what did? Bad info video.

That's because this government agency actually employs scientists. I'm sure it has its share of bureaucrats, but I have a feeling they're allergic to KZbin.

[@usgs]

@@michaelbballard It's not a hydrovolcanic eruption. The water was already hot, and built up in a confined area. Physics did the rest. And activity is not increasing around the planet.

He says he's not called by volcanic activity yet the ground has risen several feet due to lava

[@usgs]

The ground has not risen several feet. Since 2015, the caldera has been subsiding at a rate of about 1-2 inches per year. Caldera deformation includes cycles of uplift and subsidence, but never by more than an inch or two a year. All of these data, from GPS stations around the park, are public, so this is pretty easy to verify.

[@Kiwigeo8339]

@@usgs Must be getting their data from Mary Greely :)

[@toastmantoasty]

First, magma must be above the crust to be called lava. Second, when they say 'not caused by volcanic activity,' what they mean is 'not directly tied to magma accumulation or formation.' If magma was building up at any appreciable rate, we would be observing several inches of uplift a *day.* Hydrothermal explosions aren't unusual with larger calderas, especially ones with large reservoirs of water in them. Sometimes all the hot water and steam can't find a relief point like a geyser or pothole, and makes one for itself.

[@brj_han]

IIRC, the "Biscuits" used to be rock formations around one of the hot pools, but the Biscuits disappeared when the hot spring blew up...

[@bradfordprophotography2816]

great video of the actual explosion/eruption

[@derdotte]

Reading the comments here shows how bad the physics education of some are. I understand thermodynamics is hard for some but people dont even notice why their pressure cooker even works the way it works. At standard atmospheric pressure, water will turn to steam when it reaches 100°C (or whatever that is in fahrenheit, cant be bothered to do the mental gymnastics to convert that), that steam doesnt get any hotter, in fact hotter environmental temperature (not water temperatures!) only increase speed of steam creation and not the temperature of said steam. Here is an experiment for you: Try measuring the temperature inside a pressure cooker by putting an analog thermometer (it is neceesary that it can go above 100°C) inside. You will find out that the temperature of the water was much higher than 100°C, how that is possible? By increasing pressure! If you suddenly open the lit of a pressure cooker (doesnt work with all pressure cookers!) then you will literally see a massive increase in steam and thats because all that water above 100°C quickly vaporizes as pressure normalizes. Do that with a large pressure cooker and you got this hydrothermal steam explosion.

[@Brielle312]

Is that crater lake in the background map behind you 💁🏻‍♀️💁🏻‍♀️ Which view can you see that caldera better at Yellowstone? Where’s the best view of the caldera of Yellowstone?

[@usgs]

The caldera at Yellowstone is tough to see because it is largely filled by lava that erupted after the caldera formed (as well as lake and glacial sediments in places like Hayden Valley). There's quite a bit of that stuff... We have some information on that at www.usgs.gov/observatories/yvo/news/lotta-lava-new-insights-timing-yellowstones-most-recent-rhyolite-eruptions. One of the better views is from the top of Mount Washburn. You're outside the caldera up there, but can look south into the caldera. And when you're driving along the Gibbon River between Norris and Madison Junctions, you're basically following the caldera rim -- to the north/west are compacted ash deposits that make up the rim, and to the south/east are lava flows that erupted within the caldera after it formed and flowed up against the margin.

[@francisvantuyle]

The trout fishing in the firehole has been tapering off for the last few years near Biscuit Basin. One of my favorite fishing places in Yellowstone. I have spoken to rangers about this but they do not know how to corrillate fishing activity to geyser activity. It seems fishermanare not viewed as reliable source of quantifiable data. Can not say I tried. I'll wait for the fire hole to clear up and give it a go next spring. Mostly brown and brook trout there. Following the fire hole on down to where it empties into the Madison is a good place to find big Yellowstone cutthroat trout. All catch and release for me.

[@43dommo]

sometimes you get localized uplift but as far as i know this was caused by a sudden weakening of the overlying ground

[@usgs]

There was nothing obvious from monitoring data, but the closest seismometer was a couple of miles away, so it might not have been detected. There are anecdotal reports of some differences in behavior of the pool in the days or hours before this event, but it's always hard to corroborate those, as these features are incredibly dynamic and are always changing. Forecasting explosions like this is a huge challenge because the water-steam transition occurs instantaneously.

I. Ant see why you said it wasn’t volcanic Magma flash heating , if you look at the recent seismologist earthquake locations at first they seem unrelated, but if you look carefully clearly looks like a fault line can be drawn right through this area if you connect the dots so to speak . If the quake has altered the underground structure, my feeling is the water is a lot closer, causing the biscuit basin explosions , or in the quakes a underground landslide has eroded. A particular underpass tunnel that might be closer to the recently disturbed magma

[@usgs]

There wasn't any seismicity that triggered this event -- that can happen, but it did not in this case. And there wasn't any involvement of magma. If there were magma, there would have been different gas emissions, and a lot of seismicity and ground deformation. You are definitely correct that the water was very close to the surface. The boulders that were thrown out by the explosion are composed of material that is present only within the upper ~150 feet of the surface. So this was definitely a shallow storage are filled with boiling water that was able to flash over to steam, causing the explosion. That's how the Yellowstone geysers and hot springs work -- the hot water is quite close to the surface.

[@ram64man]

@@usgs hmm I don’t mean direct contact , I agree that it’s definitely not like the volcanic water content causing the eruption, but as I said if you picture the earthquakes on a map , you can draw a like over this area like a plate fault , normally that pressure builds and then releases, yet the earthquakes.early over the past three weeks either side altered something below, that or erosion forming a deeper pothole , but my feeling an underground collapse has allowed more pressure to build with a greater volume , normally if it was a block landslide then I would assume that it cleared the blockage, but it didn’t there still going, not as intense naturally, so clearly that has changed from an underground landslide or a vain of magma has been diverted closer allowing more water to be super heated into steam eg there more water in the kettle
