The Yellowstone supervolcano at the Yellowstone National Park in Wyoming is mathematically overdue for another devastating eruption. Since the most recent giant (caldera-forming) eruption 631,000 years ago, approximately 80 relatively nonexplosive eruptions have occurred. Why are there so many earthquakes at Yellowstone? The most recent volcanic eruption at Yellowstone was a lava flow that occurred 70,000 years ago. The documentary found there would be very little in the way of lava flows from a volcano eruption at Yellowstone. 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. One such solution that NASA is looking. Yellowstone is a plateau high in the Rocky Mountains, and is snowbound for over six months per year. Given that volcanoes tend to erupt only when a vast amount of magma is readily available, should this finding be a cause for concern? 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. Given the inherent uncertainties, however, it is even possible that Yellowstone will never see an eruption on such a scale again. Every few thousand years, a hydrothermal explosion will form a crater as much as a few hundred meters across. In honor of our students participating in Columbia Public Schools Science Department trips to Grand Teton and Yellowstone National Park, we take a look at what mighthappen when this giant volcano will erupt. 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. "This [research] really just confirms what we already know about Yellowstone," Poland said. The supervolcano's last eruption was 631,000 years . 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 report summarizes the activities and findings of YVO during the year 2020, focusing on the Ye, Volcanic eruptions are among Earths most dramatic and powerful agents of change. 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. Thursday, December 31, 2020 6:37 AM UTC. The landslide and resulting flooding. The new research, which uses more advanced techniques but the same data, suggests it is closer to 16-20% molten. Official websites use .gov Mike Szydlowski is science coordinator for Columbia Public Schools. The take-home message is that the magma chamber is mostly solid. The last Yellowstone eruptions would have been total surprises to the existing life on Earth. Steam explosions, earthquakes, and volcanic eruptions -- what's in Yellowstone's future? This comes out to an average of about 725,000 years between eruptions. While past giant eruptions help to define a supervolcano, they are not necessarily a good indicator of how a given volcano will behave in the future, the researchers said. 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 last major eruption in Yellowstone took place a little more than 630,000 years ago. This update, Yellowstone National Park, a nearly 9,000 km2(~3,468 mi2) area, was preserved in 1872 as the worlds first national park for its unique, extraordinary, and magnificent natural features. Yellowstone National Park is unique beyond its overwhelming beauty, highest-elevation lake in North America, and abundant wildlife its geothermal features. The chamber is mostly solid, with only about 5-15% melt. All rights reserved. Winds would carry ash to the East Coast of the US in amounts that would still be dangerous to human lungs. Within the next few decades, light-to-moderate earthquakes and steam explosions are certain to occur. 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. Geologists believe it is only a matter of time before the big one strikes. It occurred on December 21st, 2012 as Earth Crust Displacement begun during the apocalypse. Volcano and earthquake monitoring plan for the Yellowstone Caldera system, 20222032, Yellowstone Volcano Observatory 2020 annual report, 2018 update to the U.S. Geological Survey national volcanic threat assessment, Geologic field-trip guide to the volcanic and hydrothermal landscape of the Yellowstone Plateau, U.S. Geological Survey Volcano Hazards ProgramAssess, forecast, prepare, engage, Protocols for geologic hazards response by the Yellowstone Volcano Observatory. How overdue is a Yellowstone eruption? Therefore, a key issue for eruption hazard assessment is to ascertain how much magma is below the surface and where.". In some cases, limited scientific drilling for research can help us understand magmatic and hydrothermal (hot water) systems; however, drilling to mitigate a volcanic threat is a much different subject with unknown consequences, high costs, and severe environmental impacts. Meanwhile, individual supereruptions can take place over periods of days to weeks, or be spread out over decades. So what might indicate that a massive eruption is imminent? 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. Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. Instead, magma would be shot with great force, most of it blasted into the sky. 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. "This is perhaps the most common misconception about Yellowstone, and about volcanoes in general. The science of forecasting a volcanic eruption has significantly advanced over the past 25 years. Just because Yellowstone has produced three very large eruptions over the last 2.2 million years doesn't mean that you should expect such an eruption. In this type of eruption, the magma blasts into the air and breaks apart into pieces called tephra. Everyone Practices Cancel Culture | Opinion, Deplatforming Free Speech is Dangerous | Opinion. Thankfully, they'll all miss. Each of the three past supereruptions of the Yellowstone hotspot spewed more than 1,000 cubic kilometers of magma into the environment the benchmark of a "supervolcano." According to Jacob Lowenstern, scientist-in-charge at the Yellowstone Volcano Observatory, that's a large enough eruption to cover much of North America in an ash blanket . In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. Millions of people would die, in the immediate . That's what a bevy of conspiracy-minded bloggers have been claiming, anyway. Will Yellowstone erupt anytime soon? RealLifeLore RealLifeLore goes on to say that lava from the volcano would destroy just about everything within a 40-mile radius of. Those farther away wont have to deal with the explosion, but the outlook mightnot be much better. 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. I find this result reassuring.". As the underground magma chamber emptied, the ground above it collapsed and created the first of Yellowstone's three calderas. 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. The park sits atop a giantsupervolcanothat last erupted around 70,000 years ago. Humans who were in its path would surely die, but it would not mean the extinction of the entire human race. Sharp volcanic ash may be the most immediate concern, but the long-term impactis worse. What type of eruption will Yellowstone have if it erupts again? Rimmed by a crescent of older mountainous terrain, Yellowstone National Park has at its core the Quaternary Yellowstone Plateau, an undulating landscape shaped by forces of late Cenozoic explosive and effusive vol, At least 170 volcanoes in 12 Statesand 2 territories have erupted inthe past 12,000 years and havethe potential to erupt again. 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. Why is volcanic ash more dangerous than regular wood ash? Huang et al., 2015/The University of Utah. The study estimated that tens of millions of people who live within a 621-mile radius of the volcano would die from the ash alone. Keep in mind that this evacuation order would go far beyond a 50-mile radius due to the amount of ash and debris that follows lava or magma substances. Why are there so many earthquakes at Yellowstone? It is, of course, more complicated than that there are many variables at play but for that reason, it makes more sense to say that a fault is 'overdue' for an earthquake.". "An obvious but key requirement for an eruption is the presence of magma," Cooper wrote in a "Perspective" article about the Science study. A supervolcano is a large volcano that has experienced at least one eruption of magnitude 8 or morethe highest value on the Volcanic Explosivity Index. Sponsored by PureCare Knee Protector The Yellowstone supervolcano thousands of times more powerful than a regular volcano has only had three truly enormous eruptions in history. Snow and ice accumulation on GPS antennas due to winter storms cause occasional apparent subsidence of 13 centimeters, but this does not represent real ground motion and recovers itself quickly once the antennas are free of snow/ice. 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. Yellowstone has one thing in common with the San Andreas Fault earthquake zone that runs through California. The debris ejected would transform into airborne ash particles and small and scorching pieces of jagged rocks, which in itself would be potentially lethal. The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit. NASA warns of 3 skyscraper-sized asteroids headed toward Earth this week. Stock image: A hydrothermal feature in Yellowstone National Park. Other 'supervolcanoes' would likely include the large caldera volcanoes of Japan, Indonesia, Alaska (e.g. There are five types of hydrothermal features readily visible in Yellowstone: Hot springs: Pools of hydrothermally heated water. A massive eruption of the Yellowstone supervolcano would spread deadly ash for thousands of miles, killing plant life and affecting humans in its path. A large volcano with at least one eruption of magnitude 8 or higher-the highest value on the Volcanic Explosivity Index-is referred to as a supervolcano. As was mentioned earlier, the Yellowstone volcano has erupted several times in the last couple million years and we still have life on Earth today. During February 2023, the University of Utah Seismograph Stations, responsible for the operation and analysis of the Yellowstone Seismic Network, located 168 earthquakes in the Yellowstone National Park region. The most recent volcanic activity at Yellowstone consisted of rhyolitic lava flows that erupted approximately 70,000 years ago. "Initial findings were that the magma chamber beneath Yellowstone was only 5-15% molten. The mean annual temperature is 2.2C (36F), barely above the freezing point of water. A recent new volcanic study made a frightening finding. In September 2004, USGS scientists detected sudden, but unmistakable, signs that Mount St. Helens was waking up. When supereruptions do occur more than once in a volcanic system, they are not evenly spaced in time. When it comes to lava and magma flows spewing forth from this volcanic eruption, Yellowstone National Park would likely need to evacuate everyone within a 40 to 50 mile radius.

"The ground surface at Yellowstone is moving all the time, sometimes up and sometimes down, and it would not be cause for concern unless it was outside the normal patterns," Kari Cooper, a professor and chair of the University of California, Davis Department of Earth and Planetary Sciences, told the Associated Press. Related: The 11 biggest volcanic eruptions in history As at many caldera systems around the world, small earthquakes, ground uplift and subsidence, and gas releases at Yellowstone are commonplace events and do not reflect impending eruptions. The Yellowstone Series, a new disaster thriller from international best-selling author B If you have questions about how to cite anything on our website in your project or classroom presentation, please contact your teacher. 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. The falling ash is not like the soft ash from a campfire. But that's not how volcanoes work. One study published in the journal Science this year found that there was significantly more magma beneath the supervolcano than previously thought. 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. 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. Immediately after and for some years they may be difficult to live in if not impossible but they will survive. This comes out to an average of about 725,000 years between Yellowstone Volcano is monitored for signs of volcanic activity. The last full-scale eruption of the Yellowstone Supervolcano, the Lava Creek eruption which happened nearly 640,000 years ago, ejected approximately 240 cubic miles of rock, dust and volcanic ash into the sky.Geologists are closely monitoring the rise and fall of the Yellowstone Plateau, which measures on average 0.6 inches yearly, as an 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.

The inhaled ash would form a cement-like mixture within the lungs, leading to gradual suffocation. They also reassure that the next eruption "won't be cataclysmic." READ MORE: Yellowstone supervolcano eruption would be disastrous for entire US - study They expect that the buildup to larger eruptions would include intense precursory activity (far exceeding background levels) at multiple spots within the Yellowstone volcano. What are some examples of supervolcanoes? 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. The Rights Holder for media is the person or group credited. 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. Official websites use .gov . While the other two calderas form a much larger portion of the park, the third caldera is considered the Yellowstone Caldera, given its centralized location within the borders of the park. Joe Phelan is a journalist based in London. Map by Alejandro Tumas Credits User Permissions The Yellowstone Volcano Observatory (YVO) is a partnership between the U.S. Geological Survey (USGS), Yellowstone National Park, the University of Utah, the University of Wyoming, UNAVCO, the Montana Bureau of Mines and Geology, the Idaho Geological Survey, and the Wyoming State Geological Survey. Recent Work and News That being the case, you might expect earthquakes to occur at somewhat regular intervals. Share sensitive information only on official, secure websites. Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. National Geographic reports that the last Yellowstone eruption was. Two of these areas produced large . Though we've been looking at Yellowstone for years, no one has yet identified "long-period (LP) events" commonly attributed to magma movement. Almost all earthquakes at Yellowstone are brittle-failure events caused when rocks break due to crustal stresses. Secure .gov websites use HTTPS Knowledge about past eruptions of Yellowstone combined with mathematical models of volcanic ash dispersion help scientists determine where and how much ashfall will occur in possible future eruptions. 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. Scientists say the last Yellowstone eruption was 1,000 times greater than the notorious 1980 Mt. This event was part of a swarm of 76 earthquakes that occurred in the area during February 411. 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. In the last 3 million years, it has erupted with tremendous force only three times. If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. The Yellowstone volcano caldera formed some 640,000 years ago and measures 34 by 45 miles (55 by 72 km) in the northwest corner of Wyoming. ", To put that into perspective, the 1991 eruption of Pinatubo in the Philippines, arguably the most powerful volcanic eruption in living memory, was rated a 6 on the Volcanic Explosivity Index, making it, according to the Natural History Museum, "around 100 times smaller than the benchmark for a supervolcano.". A .gov website belongs to an official government organization in the United States. Diagram showing the Yellowstone supervolcano magmatic system. Even when a volcano is quiet, steep volcanic slopes can collapse to become landslides, and large rocks can be hurled by powerful steam blasts. If LP events are observed, that will NOT mean Yellowstone is getting ready to erupt. That will be a problem. Many volcanoes go through cycles of activity and inactivity, Poland said. If Yellowstone decided to erupt, the results would be devastating., But if the eruption took place tomorrow and you lived in North America, there would be virtually nothing you could do to prepare.. But as long as these processes do not stray too far outside normal levels they are not considered a sign that an eruption is imminent. "This really just confirms what we already know about Yellowstone". The chamber is mostly solid, with only about 5-15% melt. How much volcanic activity has there been at Yellowstone since the most recent giant eruption? Steam explosions, earthquakes, and volcanic eruptions -- what's in Yellowstone's future? The dashed outline of the lower magma reservoir indicates that its boundaries are uncertain. The "huge mountain" in this instance is believed to be Yellowstone. Share sensitive information only on official, secure websites. The ash that gets caught in the stratosphere will stay suspended for months or even years. Most of the national park and vicinity are sparsely populated, but significant numbers of people as well as park resources could nevertheless be at risk from these hazards. An official website of the United States government. Almost all earthquakes at Yellowstone are brittle-failure events caused when rocks break due to crustal stresses. Why should your family not worry too much about the Yellowstone volcano? According to Epoch Times, multiple videos of such incidents have been posted online recently, one of which shows a herd of buffalo .
