Yellowstone Park Announces New Thermal Discovery
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A newly formed thermal feature has been discovered in the Porcelain Basin area of Yellowstone National Park's Norris Geyser Basin, officials from the Yellowstone Volcano Observatory (YVO) reported this week. Why It Matters "The discovery emphasizes the dynamic nature of Yellowstone's thermal activity. It's not evolving in any one direction or another, but it is always changing," Mike Poland, scientist-in-charge at YVO, told Newsweek. Known for its unique hydrothermal and geologic features, more than 4.5 million visitors flocked to Yellowstone, which spans 2.2 million acres across parts of Wyoming, Montana, and Idaho, in 2023, according to the National Park Service. What To Know Discovered during routine maintenance of temperature logging equipment on April 10, the pool measures approximately 4 meters (13 feet) across and was filled with light blue water registering around 109 degrees Fahrenheit. It lies west of an area informally known as "Tree Island."

View looking northwest at a new thermal pool in the Porcelain Basin area of Norris Geyser Basin, Yellowstone National Park, that probably formed in a series of mildly explosive events between late December 2024 and early February 2025. More Mike Poland/USGS Field geologists noted the presence of scattered rocks—up to 30 centimeters in diameter—around the site, coated with a light-gray, fine-grained, sandy mud. The presence of these materials, coupled with the observed structure of the pit, led scientists to conclude that the feature likely resulted from a series of minor hydrothermal explosions. The pool likely developed between late December 2024 and early February 2025, according to YVO. High-resolution satellite imagery played a crucial role in pinpointing the formation window of the new pool. Images showed no trace of the feature on December 19, 2024, but revealed a depression by January 6, 2025, and a fully developed pool by February 13, 2025. Additionally, infrasound data collected from a monitoring station installed in September 2023 detected several low-level acoustic signals originating from the direction of the new feature. The most prominent of these was recorded on December 25, 2024, though it lacked an accompanying seismic signal, indicating that the event was not a significant explosion.

USGS What People Are Saying Mike Poland, scientist-in-charge at Yellowstone Volcano Observatory, told Newsweek: "This sort of thing probably happens many times per year throughout the park. Yellowstone is an incredibly dynamic place that is always changing. New features are appearing, existing ones go quiet, and so on, all the time. But thanks to advances in monitoring capabilities, we're able to catch these changes in a way that wasn't possible previously." Yellowstone Volcano Observatory said in its report: "The latest new thermal feature in Norris Geyser Basin—perhaps the most dynamic area in Yellowstone National Park—demonstrates the spectrum of ways in which hydrothermal features evolve. Some form during brief and violent episodes of change. Others may take shape far more gradually, like the new feature found near Tree Island that seems to have begun taking shape on Christmas 2024." What Happens Next Poland told Newsweek that the new hole was sufficiently far away from boardwalks and trails to pose no threat to visitors. "But I think it is a good reminder about why it is so important to stay on marked trails and boardwalks when exploring Yellowstone's geyser basins," Poland added. "The ground is unstable, and there is a lot of steam and hot water just below the surface in places. A person could easily break through a thin crust into scalding fluids if they leave the boardwalks."

Heart wrenching: Bison falls to death into Yellowstone National Park's hot spring
1 2 Recently, a video from the famous Yellowstone National Park in the U.S. is going viral on social media. The video, which was shot in the month of June by some tourists, shows a huge bison being swallowed by a scalding hot spring in the park. It all happened in front of the tourists who couldn't do anything to save the animal. The horrifying incident is a stark reminder of the power of the nature. As per officials, the bison wandered into the Grand Prismatic Spring, which is a part of the national park. The incident took place on the morning of June 21 and was captured by the onlookers. The video doing round on social media shows the bison struggling to get out before slipping into the waters and disappearing behind the steam. Hours later, the remains of the bison was seen resting in the spring. Mike Poland, the scientist-in-charge of the Yellowstone Volcano Observatory with the U.S. Geological Survey, said that the scalding hot water of the springs will take its toll on the bison's remains. He furter said that the park rangers will leave the bison to decay naturally. Poland informed that it's note yet clear how and why bison ended up in the hot spring. But after seeing the video, he said it looked like the animal got too close, lost the balance and fell into a hot geyser. Explaining about the geysers, he said that most hot springs are actually neutral, however the temperatures are of the water is extremely height that the bison most likely boiled to death. However, it is not the first time that such an incedent had happened here. A number of animals fall victim to Yellowstone, but it is a rare sight. The incident is also a reminder to visitors, he said: 'Stay safely on the boardwalks and marked trails to avoid serious injury or death.' About Yellowstone National Park America's first national park, Yellowstone, was established in 1872. It is an iconic natural UNESCO wonder in Wyoming, with parts touching Montana and Idaho states as well. The park is mostly famous for its geothermal wonders which includes the famous Old Faithful geyser. The park is also a natural home to a range of wildlife, including bison, elk, wolves, and grizzly bears. The park attracts millions of visitors, photographers, wildlife lovers and nature enthusiasts every year from across the globe.

Visitors see bison fall into Yellowstone hot spring and die. ‘Haunting'
Some Yellowstone visitors were left reeling from witnessing a bison's last moments after the animal fell into one of the park's hot springs. The incident happened Saturday, June 21, just before 7 a.m., according to Yellowstone National Park visitors who witnessed the bison's demise. 'Unfortunately, I witnessed the bison drowning in the Grand Prismatic Springs early yesterday morning,' someone wrote in a June 22 post in the 'Yellowstone Through The Lens' Facebook group, where park and wildlife enthusiasts share photos and information about the park. 'It took a few steps into a shallow area to the right of the pool, it turned around and stepped out very quickly. It stood for a moment, then turned back towards the spring and stepped into a deeper section then couldn't get out despite trying its best.' Photos show the bison struggling in the spring, thrashing and jumping into the air to try to get away from the boiling hot water. 'These images are haunting,' someone said in the comments. While it was likely horrific to witness, it is something that happens in the park 'from time to time,' Mike Poland, scientist-in-charge at the Yellowstone Volcano Observatory, told McClatchy News in an email. 'There are occasional reports from observers of wildlife dying in hot springs,' he said in the email. 'I can't tell you exactly how many incidents there are a year (likely many that happen go unwitnessed), but it's not at all unprecedented.' Several people commented on the post, some saying it was sad while others said it was fascinating to see nature play out before them. 'What an incredible experience to witness nature's beauty and fury,' someone else said. 'Such a beautiful and dangerous place,' another person said. Another person posted photos and videos they had taken of the aftermath in the Facebook group, seeking information about the type of animal they had seen dead at the edge of the spring. They initially thought it was 'a massive bear,' they said. The photos and videos show the spring's steam causing low visibility in the basin, which some speculated might have confused the bison as it was trying to escape. 'I took a moment to contemplate the story this scene might tell, and the inevitability of life and death,' they wrote in the June 22 post. 'While a bit existential, it made for one of my most memorable experiences in nature.'

Explosion warnings at Yellowstone as popular tourist spot is closed for summer
A popular Yellowstone National Park attraction will remain closed to summer tourists as scientists monitor a rogue thermal pool that might blast again after a major explosion last July. Biscuit Basin, a popular attraction among tourists that is usually packed with visitors has been sealed off from the public since a massive explosion in July, 2024, and will remain closed during the summer season. Biscuit Basin, located just north of Old Faithful, erupted at around 10 in the morning last summer, sending a massive plume of boiling water and debris shooting into the sky - soaring hundreds of feet into the air. The dramatic blast completely destroyed the wooden boardwalk and left tourists running for safety. Miraculously, no one was injured but scientists call it one of the most powerful hydrothermal explosions in the area's recorded history. Now, given the basin's unpredictable history, scientists are unsure when or if it will blast again. 'Since the July 23, 2024, explosion, Biscuit Basin has been closed to public visitation as Yellowstone National Park assesses damage and the potential for future hazardous events,' a released stated by Yellowstone Volcano Observatory. 'We were fortunate that no one was injured during what was clearly a spectacular event,' Mike Poland, scientist in charge of the Yellowstone Volcano Observatory told the Cowboy State Daily. 'We don't have enough information to know how Black Diamond pool is going to behave going forward,' he added. Biscuit Basin, a popular attraction among tourists that is usually packed with visitors has been sealed off from the public for the entire summer season following a massive explosion in July, 2024 'We know from seismic data and eyewitnesses that there have been small bursts from Black Diamond Pool since the big explosion last July.' 'The problem is that we don't have any really good observations or documentation of these events, so that's why we installed this webcam.' The power behind these explosions comes from a deadly combination of superheated water and restricted underground plumbing that creates a pressure cooker effect beneath the earth's surface. Poland revealed that rocks blasted from the pool during July's explosion showed evidence of being 'cemented together' by silica deposits that had been building up for years. 'All of the rocks that we looked at that came out as part of that explosion showed evidence of being solidified,' he told the outlet. Miraculously no one was injured but scientists call it one of the most powerful hydrothermal explosions in the area's recorded history 'They were cemented together by silica deposited out of the hot water in Black Diamond Pool.' This essentially created an underground cork that trapped enormous pressure until it finally gave way and ended with the massive explosion. 'Silica is impermeable,' he said. 'When you build up a layer of silica, it acts like a container, sealing pressure in.' 'That's what happened to drive the explosion back in July. The pool sealed itself by depositing all the silica in areas, which allowed pressure to build and eventually generate the explosion.' Last year's explosion wasn't the first at Black Diamond Pool. On November 5, 2024, scientists collecting gas samples witnessed another violent outburst, while a winter tour group witnessed yet another eruption on January 3, 2025. But last year's was the largest in recorded history. 'The plumbing system was blown apart by that big event, but we still don't understand what the plumbing system looks like now and how it might have evolved since that big event,' Poland told the outlet. 'That's what the monitoring in the Biscuit Basin specifically aims to see.'

A wild project in Iceland could transform how we forecast volcanic eruptions
is a senior producer and reporter on Unexplainable, Vox's science podcast. She covers everything scientists don't yet know but are trying to figure out, so her work explores everything from the inner workings of the human body to the distant edges of the universe When you picture a volcano, what do you see? I personally imagine a mountain sticking up into the sky. At the top of that mountain, I see a crater with a fiery hot lake boiling and roiling in it, or lava pouring down a slope like bright red candle wax, or massive clouds of grey ash exploding into the air. It's all incredible, powerful imagery, but it's also really just the tip of the volcano-berg. If I were to descend down through my imaginary volcano, moving down through layers and layers of earth, I'd find what might be an even more incredible feature: my volcano's pulsing, fiery furnace of a heart, also known as its 'magma chamber.' This is the reason that hot ash comes bursting up through the surface. It's the original source of my lava and my crater lake. It's where much of the important action in a volcano unfolds — and could hold secrets to help us better predict when a devastating eruption will occur. The problem is that we know much less about magma chambers like this than we'd like to. We're not even good at depicting them. 'We draw them as red balloons,' says Mike Poland, a geophysicist and scientist-in-charge at the Yellowstone Volcano Observatory. 'They are not. But it's a very difficult thing to represent.' Magma chambers are so hard to represent because they're so complex. They can be thousands of degrees Fahrenheit and have blends of solid material and hot liquid rock. These chambers have different temperatures in different spots, and different minerals melting at different heats or moving around in different ways. And, making things even more complex, there's a multitude of different gases that might make pressure build up before an eruption. But if we could better represent magma chambers — and just generally better understand exactly how they work — Poland says we might be able to dramatically improve our understanding of how volcanoes operate, and therefore be better able to anticipate what to expect from an impending eruption. But right now, because these chambers are so hot and so deep underground, it's hard to plumb their secrets. 'We don't have, like, the glass-bottomed volcano where you can just sort of look into and go like, Oh, that's what's going on,' Poland jokes. But what if we could have a glass-bottomed volcano that we could sort of look into and go like, Oh, that's what's going on? What if we could build, say, a little observatory deep down under the ground, right in the hot little heart of a volcano? It sounds absurd, and yet… ' There's a project in Iceland,' Poland tells me, 'They want to build a magma observatory. They want to drill into a magma chamber and put some monitoring equipment in the hole. … That would give us some idea of what's going on in there.' The project is called the Krafla Magma Testbed, or KMT, and the researchers working on it think it could revolutionize volcanology — and how we forecast eruptions. But first, what's missing from our volcano forecasts? One of the key motivations for building an observatory like this is that volcanology has a prediction problem. On the one hand, volcanoes are much more predictable than, say, earthquakes — they tend to give us some warning signs before they erupt. But on the other hand, it's hard to perfectly interpret those warning signs, which means the predictions volcanologists can make with our existing technology can be both incredibly helpful and frustratingly imprecise. For example, for the last year or so, a potential eruption has been brewing at Mount Spurr, a volcano near Anchorage, Alaska. Twice in the last 100 years, eruptions from Mount Spurr have rained ash down on the city, clogging up roadways, shutting down the local airport (one of the busiest cargo ports in the world), and settling like a fine dusting of gritty, gray, unmelting snow on cars and lawns and leaves of trees. People are understandably worried about a repeat performance, and the Alaska Volcano Observatory is monitoring the situation closely. Matt Haney, the scientist-in-charge at that observatory, told me while he can be sure that the volcano is displaying several key warning signs, he can't be sure exactly what the upcoming volcanic activity might look like — if there will be one eruption or many, exactly how intense they will be, or when they'll occur. 'That is not possible in the current levels of technology that we have,' he said. 'There's no definitive time frame, like, Oh, it's going to do exactly this, like it did in 1992. It's not the precise same playbook.' Even with 11 seismic stations gathering real-time data about the Alaskan volcano — even with devices measuring how it is changing shape in response to incoming magma, with planes circling in the sky to understand the venting of gases, and with an enormous amount of truly impressive work — these volcanologists still can't give us as clear a picture of the future as we might like them to. That's tricky enough when you're dealing with the prospect of a clogging and choking coating of volcanic ash, but it gets even more complicated when you're trying to make determinations about people's lives. 'This is the problem. How do you know how big an eruption's going to be?' — Mike Poland, geophysicist and scientist-in-charge at the Yellowstone Volcano Observatory Look, for example, at the case of Soufrière de Guadeloupe, a volcano on the Caribbean island of Basse-Terre. In the mid-1970s, it started venting steam. That, paired with increased earthquake activity, had people worried that a dramatic eruption might be brewing. And they had very good reason to worry: In 1902, another Caribbean volcano eruption sent a deadly mix of hot gas and ash and rock careening through a nearby city at 300 miles an hour, killing 27,000 people. So, hoping to avoid a repeat of this devastating event, the governmental authorities decided to go ahead and evacuate. More than 70,000 people left Basse-Terre. But the subsequent eruption was minor. As one report put it, the 'explosive emission of steam and debris was certainly impressive to those who had the misfortune to view it at close quarters. But from a volcanological point of view, it represented a rather trivial outburst.' If anything, the biggest impact on the volcanic activity was the evacuation itself — it hurt the local economy and disrupted kids' schooling. Sometimes, though, evacuations are extremely necessary. In 1991, at Mount Pinatubo in the Philippines, volcanologists once again read the volcanic tea leaves — stuff like seismic activity and steam explosions — and predicted a big eruption. Once again, people were evacuated. But this time, the decision to abandon the area saved thousands of lives — the ensuing eruption was one of the biggest in the 20th century. 'This is the problem,' Poland says. 'How do you know how big an eruption's going to be?' You don't want to evacuate too little, or too late, at the cost of human lives, he says. But equally, you don't want to be the boy who cries wolf, or the volcanologist who cries, 'ERUPTION!' ' It erodes trust in the scientists,' he says. Volcanology has come a long way since the 1970s, or even the 1990s. Scientists have much more monitoring equipment set up on volcanoes, and they have made better equipment over time. Their ability to make predictions about volcanoes has improved dramatically as a result. But as the case of Mount Spurr shows, even now — in 2025 — the field still grapples with the same fundamental problem of precision in their predictions. So how do these predictions get better? How could volcanologists further improve their predictions in order to help people make decisions about how to prepare for eruptions? Poland has spent a fair amount of time thinking about the answers to this question. He wrote a whole paper about it, in fact. And he thinks that improving volcano forecasting is not just about continuing to improve our monitoring equipment. Instead, he says, what we really need is better information about volcanoes themselves, and the hot molten rocks that power them. What can molten rock teach us about eruptions? Let's talk about how we currently forecast volcano eruptions. A lot of volcano prediction involves making very informed guesses about what a volcano might do in the future based on what that volcano has done in the past — what Poland calls pattern recognition. Take, for example, gas emissions or earthquakes. Essentially, he says, researchers will take a lot of very, very precise measurements of those phenomena that will allow them to then say 'Alright. X is happening. And when X happened before, Y happened afterward, so maybe now Y will happen again soon.' 'It's not necessarily based on any special understanding of the physics of volcanic activity or that particular volcano,' Poland says, 'It's more based on…We've seen this movie before, and we know how it's likely to evolve over time.' Related Your weather forecast is about to get a lot worse This approach has been incredibly useful. It's saved a lot of lives and helped scientists make some really good predictions about how a volcano might behave, broadly. But Poland likes to draw a comparison between this approach and with how we forecast the weather. Because in the past, weather scientists also relied heavily on pattern matching. If the pressure was dropping and it was getting colder, say, they might expect a storm to come through. But then, weather forecasting went through a kind of revolution. Scientists used satellites and other instruments to collect information about clouds and winds and rain. They collected huge amounts of data about the atmosphere, and people even flew directly into the eyes of phenomena like hurricanes to measure what was happening inside of those storms. 'This really abundant information was then used by modelers…to work out the physics of what's going on,' Poland says. Weather scientists still use a lot of historical data to inform their understanding of the future (and now, with AI, are actually turning back to their massive bodies of data to try some more advanced pattern recognition), but they have also built really sophisticated models of the physics of the atmosphere that help them make their predictions. And it has paid off: Last year, according to the National Hurricane Center, hurricane forecasters set new records for accuracy in their predictions for the 2024 Atlantic hurricane season. 'We can now forecast, with some degree of accuracy, whether a hurricane will form, how intense it is going to be, where it's going to go,' Poland says. 'Obviously not every forecast is perfect. And that's because our knowledge is still imperfect. But they know enough.' Poland wants volcanologists to build similar models of the underlying physics of volcanoes, which would mean building models of magma chambers. Scientists have been working on making models like this — and have even been working on applying them to forecasting. But if the weather scientists built their models by flying directly into things like hurricanes and taking measurements, volcano researchers have had a bit of a harder time doing the equivalent for magma chambers. They can't take direct measurements, so they've used seismic and electromagnetic imaging to take the equivalent of X-rays of the Earth, and they've studied places where ancient volcanoes have eroded away, bringing their cooled, frozen magma chambers up to the surface. They've even read the layers of volcanic crystals as though they were tree rings. This has been helpful, but it's kind of like studying your neighbors by eavesdropping on their conversations through the wall and going through their trash instead of just talking to them directly. So that's why some researchers are hoping to talk to volcanoes directly — to observe their magma chambers in real time. Krafla volcanic area in Iceland. Getty Images/iStockphoto Introducing KMT: The Krafla Magma Testbed In some ways, the dream of a magma observatory started with an accident. Or to be a little more specific, it started with three different accidents in three different countries, each more than a decade ago. In each case, people set out to drill a deep hole into the rock near a volcano, and in each case, they accidentally drilled right down into the magma chamber. These accidents were a big surprise to the people doing the drilling, but to John Eichelberger, they were a big opportunity. Eichelberger has been studying volcanoes for around five decades. For much of that time, he's been curious about magma chambers. He thinks that knowing more about them could not only help us forecast volcanoes better, but also maybe tap into them for geothermal power. Unfortunately, he says, for a long time, it was difficult to find a way to drill into magma chambers and find out more about them, because people were not sure what would happen if you did. What if you triggered an eruption? 'Really the only way [drilling down to a magma chamber] could happen was by serendipity,' Eichelberger says. Serendipity like these three drilling accidents. They provided some real-world examples of what would happen if you drilled down to a magma chamber. And the answer was, it turns out, not all that much. In each of these three cases, the drilling companies hit the magma chamber and instead of like hot rock shooting out of their hole in a hot plume of fire, the magma basically climbed a little ways up the hole, and then cooled off into a plug of dark obsidian glass. This was very good news for Eichelberger. As he remembers it, he wound up meeting someone from a power company that was involved in one of these accidents. That representative let him know that they would be open to letting Eichelberger and other researchers do some more research near their power plant in the Krafla volcanic region of Iceland. And so, in 2014, Eichelberger gathered researchers together for a consortium – including a researcher named Yan Lavallée, now at Ludwig Maximilian University of Munich. 'Fifty or 60 of us spent the best part of a week together browsing ideas as to…what could we learn if we were to do this?' Lavallée syas, 'What could we learn if we were to drill back in the magma?' This was the start of the dream of KMT: The Krafla Magma Testbed, named for the volcanic system in Iceland. It's a dream that Eichelberger, Lavallée, and their collaborators are still trying to get funded, but they have a clear idea of how they'd make it a reality. 'First, we're going to install a drill rig at the Earth's surface, and we're going to start drilling,' Lavallée tells me. As they drill down, things will get hotter and hotter. They will pump fluid through, which will cool things down. Eventually, as they start to approach the magma of the magma chamber, the fluid will even start to cool down a little bit of that magma, too. 'It will vitrify to a glass,' Lavallée says. This glass will likely not be transparent like a window. Instead, it will be obsidian — dark black and full of minerals. The researchers will then continue to keep things cool while they carve into that black glass, creating something like a pocket within it. Once that pocket is made, they hope to drop measuring devices into it. Lavallée works with tools in his lab that are made of the same kinds of heavy-duty materials that we put into things like jet engines and other materials that can withstand extremely high temperatures. Once everything's in place, they will stop cooling things down. Then the heat of the surrounding molten rock should start warming the obsidian of the glass pocket back up again slowly, until it melts back into magma and flows back around the instruments, submerging them fully in the magma of the chamber. Then, hopefully, the researchers will finally have their observatory: a set of measuring devices feeding them real-time data about an active magma chamber. If this first project succeeds, then Eichelberger and Lavallée are brimming with ideas for further drilling projects that could help them tease out more information about volcanoes. They both hope this research could help the world tap into volcanoes as a source of power, but also that it could help with forecasting — to help us build the models of volcanoes' hearts that will give us the tools to predict their behavior as effectively as we predict hurricanes. And overall, Lavallée thinks that if this dream of theirs succeeds, it might revolutionize volcanology. 'I don't think we can really fully conceive how it's going to change things,' he says. Obviously, Lavallée has a clear reason to think this way, but when I asked Poland, who has no involvement with this project, what he thought, he was also pretty enthusiastic. 'I am excited to hear what they can come up with,' Poland said, 'I mean, you go into a magma chamber, you're going to learn some things.'
