One study published in the journal Science this year found that there was significantly more magma beneath the supervolcano than previously thought. Despite starting the problem for years and looking for strategies to reduce the impact and prevent it,NASAfindings concluded politicians would be unlikely to fund the millions necessary to minimize a Yellowstone eruption risk. Volcanologists have suggested that the ramification they are most concerned about is wind-flung ash, which could end up coating a surrounding region 500 miles (800 kilometers) across in more than 4 inches (10 centimeters) of ash. On 17 August 1959, a magnitude 7.3 earthquake struck the Yellowstone area and kicked off a 73-million-metric-ton landslide that dammed the Madison River. 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.

Given that volcanoes tend to erupt only. When was the last time Yellowstone erupted? - Anil Agga. Scientists are monitoring the volcano 24 hours a day, measuring everything from geyser eruptions, hot spring temperaturesand ground uplift. 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 largest earthquake of the month in this sequence, a magnitude 2.4 event, occurred on February 14 at 3:03 AM MST. National Geographic Headquarters 1145 17th Street NW Washington, DC 20036. Fortunately, the chances of this sort of eruption at Yellowstone are exceedingly small in the next few thousands of years. If Yellowstone does erupt again, it need not be a large eruption. The Yellowstone supervolcano is an eight out of eight on the Volcanic Explosivity Index but has only erupted three times in the last 2.1 million years. In turn, this would threaten water supplies and agriculture worldwide. 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. The Yellowstone supervolcano sits above a hotspotan area of anomalously high temperaturesin the Earth's mantle that causes melting of the material in the region. So, how do experts keep an eye on Yellowstone's subterranean activity so that, in the case of a major volcanic eruption, warnings can be given? Videos of bison seemingly fleeing Yellowstone National Park in Wyoming have sparked concerns among some bloggers that recent seismic activity could trigger the eruption of the park's so-called supervolcano. The ash that gets caught in the stratosphere will stay suspended for months or even years. 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. Answer (1 of 5): Braelynn, No, the Yellowstone Supervolcano will not erupt in 2022, nor likely ever because the magmatic hot spot that created the supervolcano which collapsed and became the Yellowstone Caldera has the North American Tectonic Plate moving slowly over it. Answer (1 of 3): I imagine all the states will survive, if there are still states at that date. Sharp volcanic ash may be the most immediate concern, but the long-term impactis worse. The last major eruption in Yellowstone took place a little more than 630,000 years ago. Volcanic ash is very sharp if you look at it under a microscope, it is like shards of glass. 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. They can blast out clouds of hot tephra from the side or top of a volcano. The most recent volcanic eruption at Yellowstone, a lava flow on the Pitchstone Plateau Yellowstone is underlain by two magma bodies.

Humans who were in its path would surely die, but it would not mean the extinction of the entire human race. 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. The next prediction will be made when it is possible to do so. 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. 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. Those farther away wont have to deal with the explosion, but the outlook mightnot be much better. 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. More often than not, a volcano's activity is a direct consequence of the magma supply. Can we drill into Yellowstone to stop it from erupting? In fact, Earths temperature would drop by an estimated 10 degrees Celsius and persist for as long as a decade.

Poland added that the effects would also be felt beyond the United States' borders. Diagram showing the Yellowstone supervolcano magmatic system. Is Yellowstone monitored for volcanic activity? 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. The ejected material would be so vast that it would quickly blanket most of the entire US and Canada. What is the most immediate danger associated with a Yellowstone eruption? Steam explosions, earthquakes, and volcanic eruptions -- what's in Yellowstone's future? When will the next large earthquake occur in Yellowstone? Will Yellowstone erupt 2020? Yellowstone's supervolcano last erupted 70,000 years ago. 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. 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. 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. The biggest difference between then and now is that the Earth did not have such a huge population of humans to feed after the last eruptions. 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. What is a supereruption? The falling ash is not like the soft ash from a campfire. 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.
