The most recent volcanic eruption at Yellowstone, a lava flow on the Pitchstone Plateau Yellowstone is underlain by two magma bodies. Thus defined, the Yellowstone Supervolcano is the volcanic field that produced the latest three supereruptions from the Yellowstone hotspot; it also produced one additional smaller eruption, thereby creating the West Thumb of Yellowstone Lake [12] 174,000 years ago. Steam explosions, earthquakes, and volcanic eruptions -- what's in Yellowstone's future? National Geographic Headquarters 1145 17th Street NW Washington, DC 20036. Volcano monitorshad picked up the Executive SummaryThe Yellowstone Volcano Observatory (YVO) is a consortium of nine Federal, State, and academic agencies that: (1) provides timely monitoring and hazards assessment of volcanic, hydrothermal, and earthquake activity in and around Yellowstone National Park, and (2) conducts research to develop new approaches to volcano monitoring and better understand volcanic activity in the Yellow, The Yellowstone Volcano Observatory (YVO) monitors volcanic and hydrothermal activity associated with the Yellowstone magmatic system, conducts research into magmatic processes occurring beneath Yellowstone Caldera, and issues timely warnings and guidance related to potential future geologic hazards. It has happened before and it will happen again. With a previous eruption occurring a little more than 600,000 years before that. A new study has found that before a catastrophic eruption takes place, the ground will likely begin to swell up. The last Yellowstone eruptions would have been total surprises to the existing life on Earth. Secure .gov websites use HTTPS Heres how it works. The shallower one is composed of rhyolite (a high-silica rock type) and stretches from 5 km to about 17 km (3 to 10 mi) beneath the surface and is about 90 km (55 mi) long and about 40 km (25 mi) wide. However, even those beyond the 621-mile range would still be threatened. EES 0836 Yellowstone Volcano Observatory (YVO) Disasters: Geology vs. Hollywood Introduction This week, we watched a clip from the movie 2012 (2009), where the supervolcano Yellowstone erupts. The odds that the Yellowstone supervolcano will erupt are roughly the same as those that the National Weather Service estimates you'll get struck by lightning in your lifetime: 1 in 10,000. What is a supervolcano? Despite such an. Many scientists are keeping watch over the activity occurring in the Yellowstone volcano because of its potential to inflict large-scale damage in the . An official website of the United States government. The resulting volcanism has been characterized by the eruption of voluminous rhyolites and subordinate basalts but virtually no lavas of intermediate composition. Learn more:Yellowstone Volcano Observatory. "Neither condition is in place at Yellowstone right now," he added. Of courseit will. Why is volcanic ash more dangerous than regular wood ash? This movementin particular uplift, or elevation of the groundcan be a sign that magma is moving toward the surface but this is not necessarily an indicator of an imminent eruption. This eruption 2.1 million years agoamong the largest volcanic eruptions known to mancoated 5,790 square miles with ash, as far away as Missouri. If breathed in, the ash will cut up your lungs and will also form a cement in your body. Castle currently has no prediction available. Secure .gov websites use HTTPS Share sensitive information only on official, secure websites. Media reports have often claimed that Yellowstone is due to erupt. The landslide and resulting flooding. Besides intense earthquake swarms (with many earthquakes above M4 or M5) we expect rapid and notable uplift around the caldera (possibly tens of inches per year). In a related report by The Inquisitr, it's claimed that the recent Yellowstone earthquakes won't trigger a volcano, but scientists have acknowledged that if a Yellowstone volcano were to erupt the Continue reading Yellowstone . Any interactives on this page can only be played while you are visiting our website. Those farther away wont have to deal with the explosion, but the outlook mightnot be much better. The explosion will be so powerful that huge amounts of ash will be ejected into the stratosphere. Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely. He is drawn to the weird, wonderful and under examined, as well as anything related to life in the Arctic Circle. Hazardous volcanic conditions might la, When erupting, all volcanoes pose a degree of risk to people and infrastructure, however, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location. If a media asset is downloadable, a download button appears in the corner of the media viewer. Yellowstone is a plateau high in the Rocky Mountains, and is snowbound for over six months per year. Given that supervolcanoes often go through periods of unrest, including seismic activity, ground deformation, and gas emissions, the monitoring of these processes must contend with the challenge of differentiating "normal" unrest from signs that an eruption is imminent, the authors of the Nature study wrote. This do, Yellowstone, one of the worlds largest active volcanic systems, has produced several giant volcanic eruptions in the past few million years, as well as many smaller eruptions and steam explosions. Thankfully, they'll all miss. Chart and map of ancient eruptions of Yellowstone supervolcano. The pool of magma underneath Yellowstone is huge, and it will take days or weeks to empty. Other recent research has examined the processes taking place under the ground in the Yellowstone region, shedding light on the eruptive potential of the volcano. The ejected material would be so vast that it would quickly blanket most of the entire US and Canada. YELLOWSTONE VOLCANO OBSERVATORY MONTHLY UPDATE U.S. Geological Survey Wednesday, February 1, 2023, 10:31 AM MST (Wednesday, February 1, 2023, 17:31 UTC) YELLOWSTONE (VNUM #325010) 4425'48" N 11040'12" W, Summit Elevation 9203 ft (2805 m) Current Volcano Alert Level: NORMAL Current Aviation Color Code: GREEN. The Yellowstone Caldera Eruption of 2012 was a cataclysmic event marked by the eruption of the Yellowstone Caldera in Yellowstone National Park. Many aspects of our daily lifeare vulnerable to volcano hazards,including air travel, regionalpower generation and transmissioninfrastructure, interstatetransportatio, Yellowstone, one of the worlds largest active volcanic systems, has produced several giant volcanic eruptions in the past few million years, as well as many smaller eruptions and steam explosions. Ever since the 4.8 earthquake that struck the park on March 30 the largest . Yellowstone Caldera. NASA warns of 3 skyscraper-sized asteroids headed toward Earth this week. "Given Yellowstone's past history, the yearly probability of another caldera-forming eruption could be calculated as 1 in 730,000 or 0.00014%. The gigantic volcano in Yellowstone has erupted three times over the last two million years, covering a huge area of surrounding land. When was the last time Yellowstone erupted? If Yellowstone does erupt again, it need not be a large eruption. This eruption was so violent that people say this is much more worser than the last eruption 640,000 years ago, In fact this eruption was so violent that researcher's have found as much as 5 feet of ash in Europe. And the study isnt talking about a few inches it is talking possibly several or more meters. In the next few hundred years, hazards will most probably be limited to ongoing geys, This region of Yellowstone National Park has been the active focus of one of the Earth's largest magmatic systems for more than 2 million years. In Yellowstone, ground uplift, for example, can be caused by other factors other than upward magma movements, like water or gas accumulation. The most recent volcanic eruption at Yellowstone was a lava flow that occurred around 70,000 years ago, but scientists think it has the potential to erupt in the future, given that there is. Having said that, eruption forecasting has significantly improved in the past two decades or so, and there are now a number of signs scientists can look for that may be giveaways of an imminent eruption. This comes out to an average of about 725,000 years between eruptions. These eruptions occurred around 2.1 million years ago, 1.3 million years ago, and around 631,000 years ago, creating the calderamassive craters that form when a volcano erupts and collapsespresent today. Since the giant explosion 631,000 years ago, there have been dozens of smaller eruptive events leading right up until the lava flow of 70,000 years ago. Given that volcanoes tend to erupt only when a vast amount of magma is readily available, should this finding be a cause for concern? YVO scientists monitor seismic activity with a network of seismographs, and track ground deformation, or movement of the Earth's surface, using a combination of Global Positioning System and InSAR (Interferometric Synthetic Aperture Radar) satellite-based techniques. Why the Yellowstone Supervolcano Could Be Huge Smithsonian Channel 4.03M subscribers Subscribe 35K 5.3M views 7 years ago One of the world's largest supervolcanoes erupted 2.1 million years ago. Between the ash, lack of sunlight, and colder temperatures, finding food to eat is going to be the most dangerous consequence of a super-volcanic eruption. Hazardous volcanic conditions might la, When erupting, all volcanoes pose a degree of risk to people and infrastructure, however, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location. Though we've been looking at Yellowstone for years, no one has yet identified "long-period (LP) events" commonly attributed to magma movement. While extremely unlikely, such an event would be catastrophic, resulting in the ejection of vast amounts of ash and debris into the atmosphere that could have the potential to affect the global climate. The ash, along with different volcanic gases, will block out much of the suns energy. The most recent volcanic eruption at Yellowstone was a lava flow that occurred 70,000 years ago. The science of forecasting a volcanic eruption has significantly advanced over the past 25 years. If one could even call it that, one positive benefit would be a huge reduction in global warming. When Yellowstone does erupt, it won't be like Hawaii and it won't even be like Mount St. Helens. All rights reserved. Volcanic debris from these eruptions has been discovered as far south as Louisiana and as far west as California.

The region's most recent caldera-forming eruption 640,000 years ago created the 35-mile-wide, 50-mile-long (55 by 80 km) Yellowstone Caldera. "This [research] really just confirms what we already know about Yellowstone," Poland said. 'High Threat' Earthquakes Looming Over US Supervolcano: What Stars Foretell ? Earthquake sequences like these are common and account for roughly 50% of the total seismicity in the Yellowstone region. The most likely explosive event to occur at Yellowstone is actually a hydrothermal explosion (a rock hurling geyser eruption) or a lava flow. Despite the tools now available to scientists, one study published in the journal Nature Reviews Earth and Environment last year found that giant supervolcano eruptions are hard to predict because they are so diverse in the rapidity of onset, duration of eruption, and triggering mechanisms, among other factors. Many volcanoesparticularly calderas like Yellowstoneshow signs of uplift and subsidence for many thousands of years without ever erupting. The largest of these flows formed the Pitchstone Plateau in southwestern Yellowstone National Park. The Yellowstone Caldera the cauldron-like basin at the summit of the volcano is so colossal that it is often called a "supervolcano," which, according to the Natural History Museum (opens in new tab) in London, means it has the capacity to "produce a magnitude-eight eruption on the Volcanic Explosivity Index, discharging more than 1,000 cubic kilometers [240 cubic miles] of material. His work has appeared in VICE, National Geographic, World Soccer and The Blizzard, and has been a guest on Times Radio. The supervolcano, or caldera, sitting under Yellowstone National Park is nearing a cataclysmic eruption, and the government has been silently evacuating local towns in preparation. Sharp volcanic ash may be the most immediate concern, but the long-term impactis worse. Since the most recent giant (caldera-forming) eruption 631,000 years ago, approximately 80 relatively nonexplosive eruptions have occurred. Joe Phelan is a journalist based in London. The debris ejected would transform into airborne ash particles and small and scorching pieces of jagged rocks, which in itself would be potentially lethal. Steam Explosions, Earthquakes, and Volcanic EruptionsWhats in Yellowstones Future? It was quite frankly, Earth's greatest killer. So what might indicate that a massive eruption is imminent? Yellowstone's supervolcano last erupted 70,000 years ago. The magmatic system at depth remains active and drives the massive hydrothermal circulation, 12201 Sunrise Valley Drive Reston, VA 20192, Region 2: South Atlantic-Gulf (Includes Puerto Rico and the U.S. Virgin Islands), Region 12: Pacific Islands (American Samoa, Hawaii, Guam, Commonwealth of the Northern Mariana Islands), Forecasting Ashfall Impacts from a Yellowstone Supereruption.

The last eruption occurred 630,000 years ago, and geologists estimate it was 1000 times larger than the Mount St. Helens eruption in 1980. What caused Yellowstone's past eruptions, and how do we know? The chamber is mostly solid, with only about 5-15% melt. These eruptions do not happen at regular intervals making them difficult to predict, not to mention the fact that there is no direct way to see what is going on beneath a volcano. While there are some (to put it mildly) inaccuracies with the clip, fascination surrounds the volcano. Right near the article's opening, I wrote: "To be clear, the new research does not indicate that the supervolcano that created Yellowstone's calderawhich last erupted 640,000 years ago . Official websites use .gov The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning that at one point in time it erupted more than 1,000 cubic kilometers (240 cubic miles) of material. The deeper reservoir is composed of basalt (a low-silica rock type) and extends from 20 to 50 Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth's surface. There's nothing static about Yellowstone's geothermal features, Hesler said. Fortunately, the chances of this sort of eruption at Yellowstone are exceedingly small in the next few thousands of years. They claim that because the last eruption of the supervolcano was 70,000 years ago (opens in new tab), it's bound to blow soon. Future US, Inc. Full 7th Floor, 130 West 42nd Street, RealLifeLore RealLifeLore goes on to say that lava from the volcano would destroy just about everything within a 40-mile radius of. Many volcanoes go through cycles of activity and inactivity, Poland said. Every few thousand years, a hydrothermal explosion will form a crater as much as a few hundred meters across. Volcano and earthquake monitoring plan for the Yellowstone Caldera system, 20222032, 2018 update to the U.S. Geological Survey national volcanic threat assessment, U.S. Geological Survey Volcano Hazards ProgramAssess, forecast, prepare, engage. Overview. Research published in the journal Science (opens in new tab) in December 2022 found that the Yellowstone caldera holds more liquid molten rock than previously estimated. As Yellowstone has been continuously monitored for about 30 years, scientists say, that there have been no indications that the volcano will erupt in 10 months, or even 10 years. The explosion of the Toba supervolcano, located on the modern island of Sumatra, some 74,000 years ago was Earth's largest volcanic eruption in the past 28 million years and formed a caldera. For example, if and when Yellowstone does erupt again, the most likely outcome would be a hydrothermal eruption, which is characterized by violent explosions that eject steam, water, mud, and rock. It occurred on December 21st, 2012 as Earth Crust Displacement begun during the apocalypse. Yellowstone's next major eruption will probably be centered in one of three parallel fault zones running north-northwest across the park, a new study predicts. Everyone Practices Cancel Culture | Opinion, Deplatforming Free Speech is Dangerous | Opinion. Researchers at the Yellowstone Volcano Observatory (YVO) are constantly monitoring the region for such signs using an array of technologies that provide real-time information. Yellowstone was not an ordinary volcano. 1996 - 2023 National Geographic Society. But the scientists said the amount of melt is significantly lower than required for an eruption to occur in the near future. Its Old Faithful geyser is world-renowned and a visual reminder of the hotbed of activity going on beneath the surface. The largest of these flows formed the Pitchstone Plateau in southwestern Yellowstone National Park. READ MORE: Ground RISING after 121 earthquakes strike . The most likely explosive event to occur at Yellowstone is actually a hydrothermal explosion (a rock hurling geyser eruption) or a lava flow. Yellowstone National Park sits on top of one of the Earths hot spots. 2022 Weather Pro Live. However, rumors of an imminent major eruption had no scientific backing. Even so, the math doesnt work out for the volcano to be overdue for an eruption. The inhaled ash would form a cement-like mixture within the lungs, leading to gradual suffocation. While it is possible that another eruption will occur in the future given Yellowstone's history and the presence of magma, scientists simply do not know when such an event will happen again nor what it will look like. The largest event of the month was a minor earthquake of magnitude 2.9 located about 11 miles northeast of West Yellowstone, Montana, on February 7 at 8:44 PM MST.

Will Yellowstone erupt anytime soon? Winds would also carry ash to Europe and the rest of the world, where it could trigger extreme weather changes. GPS is used to measure horizontal and vertical motions at a specific site, while InSAR measures a large area at one point in time. Yellowstone has endured three major caldera-forming eruptions within the past 2 million years. In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. Ash, mudflows, and lava flows can devastate communities near volcanoes and cause havoc in areas far downwind, downstream, and downslope. A caldera-forming eruption would create a massive natural hazard in Yellowstone. The most recent volcanic activity at Yellowstone consisted of rhyolitic lava flows that erupted approximately 70,000 years ago. She or he will best know the preferred format. The Yellowstone supervolcano at the Yellowstone National Park in Wyoming is mathematically overdue for another devastating eruption. Yellowstones steaming attractions bring in millions of visitors who enjoy the spectacular sights. A short documentary by What If asks: What if the Yellowstone Volcano erupted tomorrow? The documentary runs a Yellowstone Volcano eruption simulation to explore what the subsequent effects would be,the Expressreported. Volcanoes don't work on timelines," Michael Poland (opens in new tab), a geophysicist and the scientist-in-charge at Yellowstone Volcano Observatory, told Live Science in an email. The Yellowstone Series, a new disaster thriller from international best-selling author B Geologists believe it is only a matter of time before the big one strikes. Diagram showing the Yellowstone supervolcano magmatic system. The scientists also believe that this swelling will take place for many years prior to the next eruption possibly as many as several hundred years. Most volcanic systems that have a supereruption do not have them multiple times. The new research, which uses more advanced techniques but the same data, suggests it is closer to 16-20% molten. In fact, over half of the worlds geysers and hydrothermal features reside in Yellowstone. Consider the scale of things: Let's say that the criteria presented in (1) and (2) suggest an eruption is in the works because the evidence is coming from all over the caldera and YVO agrees an . 3.

Wednesday, March 1, 2023, 9:30 AM MST (Wednesday, March 1, 2023, 16:30 UTC), There were no recorded eruptions of Steamboat Geyser during the month of February, and the total number of eruptions for the year remains at two. So where does the idea of Yellowstone being "overdue" for an eruption come from, then? Related: The 11 biggest volcanic eruptions in history What are some examples of supervolcanoes? Though we've been looking at Yellowstone for years, no one has yet identified "long-period (LP) events" commonly attributed to magma movement. If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. UPDATED VERSION - https://youtu.be/O3-X3CNsVVsI know that Yellowstone eruption will be much more powerful than this, but this is hardly working on my pc it f. The most recent volcanic eruption at Yellowstone was a lava flow that occurred around 70,000 years ago, but scientists think it has the potential to erupt in the future, given that there is hot, fluid or semi-fluid material present beneath the ground (magma) as evidenced by the abundance of hydrothermal features and frequent seismic activity in the area. In the case of a large eruption, scientists expect that the period beforehand would be characterized by intense activity far exceeding normal background levels in various locations across the Yellowstone supervolcano. Grand is predicted to erupt at 9:00pm 90 minutes on August 21, 2022. Secure .gov websites use HTTPS The authors of the Science article found that more melt was present than had previously been recognized and that it was located at shallow depths in the crustin the depth range where previous eruptions were sourced. From that day forward, John's work with AI became a benchmark for how technology and human . Yellowstone earthquake activity is currently at background levels. In the next few hundred years, hazards will most probably be limited to ongoing geys, This region of Yellowstone National Park has been the active focus of one of the Earth's largest magmatic systems for more than 2 million years. The Yellowstone supervolcano has unleashed three cataclysmic eruptions in the past 2.1 million years; all well before humans populated North America. Huang et al., 2015/The University of Utah. This event was part of a swarm of 76 earthquakes that occurred in the area during February 411. Most scientists think that the buildup preceding a catastrophic eruption would be detectable for weeks and perhaps months to years. Why are there so many earthquakes at Yellowstone? They expect that the buildup to larger eruptions would include intense precursory activity (far exceeding background levels) at multiple spots within the Yellowstone volcano. The take-home message is that the magma chamber is mostly solid. Almost all earthquakes at Yellowstone are brittle-failure events caused when rocks break due to crustal stresses. ThisEarthWord is straight up steampunk New study investigates groundwater from the air, Executive SummaryThe Yellowstone Volcano Observatory (YVO) is a consortium of nine Federal, State, and academic agencies that: (1) provides timely monitoring and hazards assessment of volcanic, hydrothermal, and earthquake activity in and around Yellowstone National Park, and (2) conducts research to develop new approaches to volcano monitoring and better understand volcanic activity in the Yellow, The Yellowstone Volcano Observatory (YVO) monitors volcanic and hydrothermal activity associated with the Yellowstone magmatic system, conducts research into magmatic processes occurring beneath Yellowstone Caldera, and issues timely warnings and guidance related to potential future geologic hazards. A .gov website belongs to an official government organization in the United States. In fact, Earths temperature would drop by an estimated 10 degrees Celsius and persist for as long as a decade. 5. Almost all earthquakes at Yellowstone are brittle-failure events caused when rocks break due to crustal stresses. But not only was the park open, but the ground in Yellowstone has also actually been subsiding, or deflating, in recent years. Yellowstone is one of a dozen supervolcanoes on Earth, each at least seven times more powerful than Mount Tambora, which produced the biggest recorded eruption in history. "Initial findings were that the magma chamber beneath Yellowstone was only 5-15% molten. "Continued monitoring of the subsurface should provide a clear picture if the situation begins to dramatically change," the researchers wrote in the paper. Therefore, a key issue for eruption hazard assessment is to ascertain how much magma is below the surface and where.". The Yellowstone supervolcano thousands of times more powerful than a regular volcano has only had three truly enormous eruptions in history. Of these eruptions, at least 27 were rhyolite lava flows in the caldera, 13 were rhyolite lava flows outside the caldera, and 40 were basalt vents outside the caldera. Right now, in the US, one of the worlds largest volcanoes is gearing up to explode, the narrator of the documentary noted. During the three caldera-forming eruptions that occurred between 2.1 million and 640,000 years ago, tiny particles of volcanic ash covered much of the western half of North America. Map by Alejandro Tumas Credits User Permissions Many aspects of our daily lifeare vulnerable to volcano hazards,including air travel, regionalpower generation and transmissioninfrastructure, interstatetransportatio, The Yellowstone Plateau hosts an active volcanic system, with subterranean magma (molten rock), boiling, pressurized waters, and a variety of active faults with significant earthquake hazards.
