At least 170 volcanoes in 12 States and 2 territories have erupted in the past 12,000 years and have the potential to erupt again. Does rational science have room for irrational belief? Following the 1991 eruption of Mount Pinatubo in the Philippines, cooler than normal temperatures were recorded worldwide and brilliant sunsets and sunrises were attributed to this eruption that sent fine ash and gases high into the stratosphere, forming a large volcanic cloud that... Vazquez, J., Stelten, M., Bindeman, I., and Cooper, K., 2017, A field trip guide to the petrology of Quaternary volcanism on the Yellowstone Plateau: U.S. Geological Survey Scientific Investigations Report 2017–5022–Q, 68 p., https://doi.org/10.3133/sir20175022q. Experts in these matters believe that a massive Yellowstone super-eruption would damage buildings and shut down power plants. A caldera is a large, usually circular volcanic depression formed when magma is withdrawn or erupted from a shallow underground magma reservoir. Could a single volcanic eruption destroy all life on Earth? Yellowstone National Park is American’s first national park and is an amazing place to see some unique hydrothermal features found in few other places in the world. The caldera formed during the last of … Citizens might be mildly … Volcanic ash fallout of more than 39.4 inches (one metre) would blanket Yellowstone’s immediate vicinity in the states of Wyoming, Montana and Utah. Experts believe a Yellowstone eruption would inject 2,000 million tonnes of sulphur 40-50km above the Earth's surface. Below the surface of this outdoors person's paradise lurks another natural wonder, however — one that has the potential to wipe the park off the map. Could a large Yellowstone eruption significantly change the climate? USGS Scientist-in-Charge of Yellowstone Volcano Observatory, Jake Lowenstern, answers If yellowstone erupts on the scale which it has in history a massive caldera would most likely result, a 'huge crater' would not necessarily be created, i.e. Almost certainly not. The Yellowstone Volcano Observatory closely monitors earthquake activity, ground deformation, streamflow and stream temperatures in the Yellowstone area. That's not to mention the variety of wildlife that call the park home, including grizzly bears, moose, elk, beavers and bighorn sheep. We had the pleasure of visiting Yellowstone in our 25 foot RV during our June crossing of America. The eruption could be expected to kill as many as 90,000 people immediately and spread a 10-foot (3-meter) layer of molten ash as far as 1,000 miles (1,609 kilometers) from the park. That depends on who you ask and which way the prevailing winds are blowing when the eruption occurs. in less than 1 second. ", "What is a Supervolcano? The Yellowstone supervolcano is a massive source of granitic magma that rests miles under the park's surface. 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. A map can be a symbolic depiction highlighting connections between components of a distance, such as items, locations, or themes. Since the most recent giant ( caldera-forming ) eruption 631,000 years ago, approximately 80 relatively nonexplosive eruptions have occurred. Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely. If Yellowstone erupts, will it be the "big one" modeled in this recent article?

The past 20 eruptions at Yellowstone have been lava flows with no significant amounts of ash fall outside of Yellowstone. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate. By early May 19, the eruption had stopped. Wind carried sulfur aerosol and the lightest ash particles around the planet and likely caused a notable decrease in temperatures around the globe. Yellowstone isn't just an American treasure; it's the world's oldest national park. (May 16, 2015) http://www.ryot.org/supervolcano-yellowstone-volcano-will-it-erupt/765673, U.S. Geological Survey. 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. If the findings sound far-flung, so to speak, researchers point out that Yellowstone’s last … The most recent was Most of Yellowstone National Park sits inside three overlapping calderas. In this image, the distance from the erupting vent to the upper left corner of the image. That would create a mixture of magma, rocks, vapor, carbon dioxide and other gases. Odds are very high that Yellowstone will be eruption- free for the coming centuries. The science of forecasting a volcanic eruption has significantly advanced over the past 25 years. This ash might reach so far that you'd see a fine dusting of it on your car in New York. What would happen if a "supervolcano" eruption occurred again at Yellowstone? The ash would block off all points of entry from the ground, and the spread of ash and gases into the atmosphere would stop most air travel, just as it did when a much smaller volcano erupted in Iceland in 2010 [source: Lemas]. The eruption of the Yellowstone supervolcano would be disastrous, so it's good to know that it probably won't blow again any time soon. USGS emeritus geologist Patrick Muffler describes his career working on Yellowstone geysers and hydrothermal systems from the 1960's through 2014. It is often difficult to visualize how calderas form. Ash Coating from Rabaul Volcanic Eruption, Satellite image of eruption cloud from Pavlof Volcano in November 2014, The Yellowstone Volcano: Past, Present and Future, Inside USGS, No. The plumes from such eruptions can rise 30 to 50 km into the atmosphere, three to five times as high as most jets fly. Yellowstone National Park is home to more than 500 geysers. ","Why are there geysers at Yellowstone? Its crater is 72 kilometers (45 miles) across, and its underlying plumbing contains several tens of thousands of cubic kilometers of magmatic material. Most scientists think that the buildup preceding a catastrophic eruption would be detectable for weeks and perhaps months to years. If that doesn't put you at ease, rest assured that the USGS has calculated the yearly risk of an eruption and it's pretty low, coming in at 1 in 730,000 — or that aforementioned 0.00014 percent chance. "When Yellowstone Explodes." When will Yellowstone erupt? Yellowstone's plume of ash, lava, and volcanic gases would reach a height of fifteen miles or more, and from this lofty position, be blown across North America. a caldera on the scale of 10's of km is possible but nothing much bigger.

So if you're planning a trip there, you shouldn't be too concerned. the following questions to explain volcanic eruptions at Yellowstone: When was the last supereruption at Sulfuric gases released from the volcano would spring into the atmosphere and mix with the planet's water vapor. In addition to the enormous expense and technological difficulties in... Kīlauea Volcano is renowned for its relatively benign eruptions of fluid lava flows. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. In fact, that's what many climate scientists believe happened in C.E. The study suggested that the supervolcano would not erupt soon, though. Yellowstone is one of a few dozen volcanoes on earth capable of "supereruptions" that expel more than 1,000 cubic km of ash and debris. 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. The caldera and most of the park are located in the northwest corner of Wyoming. That ash was likely a third of a meter deep several hundred kilometers from Yellowstone and several centimeters deep farther away (see this map). The Yellowstone Plateau is one of the largest manifestations of silicic volcanism on Earth, and marks the youngest focus of magmatism associated with the Yellowstone Hot Spot. ", "What is a Caldera?
