@@shaynejenkins446 That is not the point....The problem is that people build in unstable areas like ocean beaches, and then get wiped out during a catastrophe. If they have insurance, good for them.

Every single person in the proximity of that event was astonishingly fortunate, and many of them were children. That entire situation could have turned out horrifyingly worse.
Very very true. The original video I saw from the aunt of two kids showed a big chunk taken out of a bench near the explosion where a rock crashed through. Imagine what it could have done to a human.
They were incredibly lucky. The water in those pools is boiling hot, apparently. Imagine getting a faceful of that, no thanks. Exciting to watch from a safe distance, however! I love the dangerous wildness of Yellowstone...makes it even more beautiful to me.
USGS, I saw this same image with flames in it on another YT site. I ignored its end-of-the-world headline title and told myself to wait for the objective truth. And here it is.

Blessings on your good work for our country.
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
@@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.
@@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.
@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.
Very cool event! I was there two years ago and fished in the Firehole River. Amazing to see the steam rising from Biscuit Basin while trout fishing in a cold stream!
Mike Poland is awesome. Been watching him for years in PBS/Horizon documentaries. A very good communicator. Glad the USGS had him do this to counter some of this crazy misinformation about what happened here.
Mike Poland is the Scientist in Charge of the USGS Yellowstone Volcanic Observatory, so he is the expected person to communicate the information about this event and others in Yellowstone.
As crazy as Yellowstone is I will go there one day I think I just have to see it for myself !! This USGS channel is the best they provide so much information and great videos thanks so much !!!!
I saw it first when I was 5 years old, way back in 1953, a kid from a little farm in Western Kansas who had never even seen rocks, let alone geysers and mountains and huge lakes and brilliantly colored pools of hot water . 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.
Many parks you can visit depending on what you're looking for. Just probably do some research because the tourist season can really pack some of them. And just driving in and out of some highways can take several hours.
We were there days afterward and were wondering why this area was closed off. Pretty amazing. Also amazing that no one was hurt, especially since there were a bunch of people there- you can see them running away in those clips.
What happens should Jellystone, Yosemite, new Madrid and the PNW subduction earthquake all happen at once? Not likely, but,it is something to think about.!!
Yellowstone is in no danger of erupting. In fact, volcanic activity at Yellowstone has been steadily decreasing ever since we began monitoring it. It may even be going extinct.
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. I usually go with the rule of thumb that if normal people are scared, you can be alert, but not alarmed. If experts in the field are scared, THEN you should start being scared as well as alert!
As a former geologist who once did a summer with the USGS in Menlo Park, I appreciate your updates to get a bit more information scientifically speaking than one can often get with the general media.
Who thinks that this kind of content needs to be attached as a link to every social media post? Let the crazies' fight it out for attention without dragging ordinary folk down the rabbit hole. Social media apps are turning society into a children's playground. This video reminded me how to deal with news items like grown ups.
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.
Unfortunately I fear that the park lawyers will overreact and keep the public a mile away from anything with any chance of popping and we won't be able to see anything anymore ☹ Thank you for the concise video 👍
how fortunate to have such spectacular footage! i read somewhere that mineral deposits can cause blockages, high pressures and releases like this, and as such is more an accumulation of force as opposed to a broad front of water flashing to steam from the collapse of a pocket or other sudden event
Would love to hear your account of that! We wrote a "Caldera Chronicles" article about that event at www.usgs.gov/observatories/yvo/news/day-porkchop-geyser-exploded.
@usgs September is a fantastic time to visit the park. There are only a few visitors. Fly fishing is great. The elk are in the park and easy to see. There were very few people in that basin when Pork Chop was explosive. I was close by and it was noisy. Lots of rocks flying.
For a government agency, that was a surprisingly, clear, concise, and informative video. It was just the perfect length it needed to be. Didn't drag out the information and gave enough insight in a short amount of time. Good work. Now wouldn't it be nice if the Secret Service or the FBI could follow the USGS lead and provide us with clear, concise reporting of events that relate to national security.
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 UA-cam.
@@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. It might seem that way to to uneven media attention and our biased human perceptions, but the planet is doing what it always has.
I honestly believe society is changing in the way it's using social media. Honest and stable people and organisations are going to learn how to cope and ignore conspiracies and misinformation. At the moment it all seems out of control, but that's because it's still a relatively new phenomenon. We'll adapt and will naturally understand quality information like this video from the voodoo that seems to be taking over.
Google must have gotten their algorithms working because it finally led me to something fascinating. I am happy to hear everyone was safe. Fun and informational video!
@USGS Could you - after things calm down - do a follow up showing the rocks and minerals involved perhaps ecen with microslides? I feel that this is a wonderfull opportunity to show the play between lithology and the hydrothermal activity.
Definitely. We'll probably do a series of Caldera Chronicles articles on this -- that's our weekly article about some aspect of Yellowstone geology (you can see past articles and sign up to get them via email at www.usgs.gov/volcanoes/yellowstone/caldera-chronicles). The one that comes out Monday morning will contain details about the initial examination of the deposit. There are lots of past articles on hydrothermal explosions in general (for example, www.usgs.gov/observatories/yvo/news/hydrothermal-explosions-yellowstone-national-park).
📋 *Very informative and reassuring report.* Thanks for pointing out the regularity (~three per year) and that these events are under-appreciated, as they are not well understood by the public. It's great that you lead by dispelling fear related to volcanic activity (notably the FUD related to Yellowstone Caldera.) Making this data available to the public in an easy to digest format is just what's needed, and it's appreciated. _Please keep making this content and sharing it to raise awareness._ 🏞
It was a beautiful eruption. It's great when a visit to Yellowstone Park also includes a bit of adventure. It really makes visitors realise where they are and what surprises nature can deliver. In my opinion, such happenings make the park really attractive.
Ok that was so cool. Glad I wasn't there. Weirdly I wanted to see something like this since high school in the 80ties. Earth science is so frigging cool
The walkway didn't fare so well this time. Natural hazards abound in Yellowstone, yet it remains one of the most beautiful and awe inspiring places on Earth.
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.
Thankyou for the update, hydrothermal activity is fascinating both chemically and physically, awesome when you think that life on earth potentially started in a place just like Diamond or Opal pool.
Excellent historical note! We have more on the history of the "biscuits" in one of our weekly Caldera Chronicles articles: www.usgs.gov/observatories/yvo/news/yellowstones-famous-biscuits.
COOL CHANNEL! I'm glad nobody was hurt. It's easy to get a false sense of security if you stay on the boardwalks. I'm also glad that Old Faithful didn't get totally messed up from the giant earthquake. It's so amazing that something like that exists and that everyone can see at least one geyser erupt when they visit. That's really special.
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.
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.
Non-government geologists are giving the same explanation. If there were really something to worry about at Yellowstone, not only would "government employees" be sounding the alarm, so would every geologist in the world!
Steamboat woke back up a few years ago after being dormant for a long time. Those first eruptions threw mud and rock into the air just like this one. That very same geyser in Biscuit Basin has exploded with an eruption like that before. Exact same place. It happens
"Whew! That was a narrow escape. Now let's go over and pet those fluffy cows."
Those fluffy cows are scary when they're walking right next to your car.
😂
Gotta love the Turons!
Yellowstone is what it was like for our hunter-gatherer ancestors on the day-to-day. How did we even survive prehistoric times??
I wish this was not so incredibly accurate.
Glad no one was hurt! Yellowstone is an amazing place!

great video of the actual explosion/eruption
That was a useful and informative report. Thanks!
Water and steam on high pressure and heat result in local hydrothermal explosion.
I think we are fortunate to live in a time when we have a natural wonder of this magnitude.
That was a powerful hydrothermal blow out. I am glad no one was hurt
The people in that iconic video can tell others that their vacation was a real "blast".
I'm just glad everyone is okay.
Very well done and informative. Great video! :)
COOL CHANNEL! I'm glad nobody was hurt. It's easy to get a false sense of security if you stay on the boardwalks. I'm also glad that Old Faithful didn't get totally messed up from the giant earthquake. It's so amazing that something like that exists and that everyone can see at least one geyser erupt when they visit. That's really special.
You guys can't enter valid timestamps captions in video, can you?
Wow look at the damage. Glad no one was injured.
Close it all for safety reasons. USGS needs to be put on Notice.
Happens all the time. It's so normal, they built a BOARDWALK right on top of it.
It wasn’t expected to happened on that side of the park, but it wasn’t inherently unusual.
Imagine seeing this in person so cool
He says he's not called by volcanic activity yet the ground has risen several feet due to lava
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.
@@usgs Must be getting their data from Mary Greely :)
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.
Thank you. Amazing blast, stay safe.
Nice to hear someone using real units instead of euro-units!
I’m always reassured listening to a government employee give explanations. lol.
Non-government geologists are giving the same explanation. If there were really something to worry about at Yellowstone, not only would "government employees" be sounding the alarm, so would every geologist in the world!
Great explanation. A lot of misinformation after this happened.
Astonishing how fortunate this was. If basically anything was different, there would've been a good chance for injuries / fatalities
Boy that must have STUNK
I see why Yellowstone is full of surprises!
Another example of just how great & spectacular this United States ALREADY is! 🇺🇸👊🙏👍💯 Ty for upload!
thanks Mr. Marsh
No problem, Stan!
(Fun Fact: Trey Parker's Dad, Randy Parker, was a USGS geologist!)
@@usgs lol, i didnt know that, lol
It was VERY lucky that no visitors were hurt.
Well spoken young fella
Yellowstone is a highly dangerous place in so many ways. Still, I would go there over any city.
Steamboat woke back up a few years ago after being dormant for a long time. Those first eruptions threw mud and rock into the air just like this one. That very same geyser in Biscuit Basin has exploded with an eruption like that before. Exact same place. It happens
Yes indeed, Biscuit Basin has a history of some decent explosions over the past 125 years.
Oh my goodness, all the people running!
