The terraces build until vents clog and pressure from gases force a weaker spot to open somewhere else. Bram Role ties a piece of rock to a tube to stabilize it in the water as he assists Ken Sims with research at Boiling River. Yellowstone, one of the world’s 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. In fact, there is no actual structure to house YVO. The last eruption, 70,000 years ago, was a relative poof compared with the climate-changing eruptions hundreds of thousands of years earlier. “If you look at the evolutionary history of life and the metabolic functions that it uses, you can map back pretty much all of those functions to an origin in a hot environment,” said Eric Boyd, a thermal biology professor at Montana State University who will work on the project. There are older volcanic systems that march their way up the plains, and as they got older and older, all of those systems eventually cooled,” Lowenstern said. The Island Park Caldera supereruption (2.1 million years ago), which produced the Huckleberry Ridge Tuff, was the largest, and produced 2,500 times as much ash as the 1980 Mount St. Helens eruption. “The initial pulse of lava flow activity was 500,000 - 600,000 years ago. Concealed beneath the park rests the Yellowstone Caldera, the largest supervolcano in North America. Please subscribe to keep reading. A supervolcano is a large volcano that has had an eruption with a Volcanic Explosivity Index (VEI) of 8, the largest recorded value on the index. They track the number and strength of earthquakes and record when the ground lifts even as little as a centimeter. Still, the debate over the volcano’s potential reflects one enduring truth about Yellowstone and the geology beneath its surface: The park remains one of the foremost research laboratories in the world, drawing internationally renowned scientists studying everything from earthquakes to the origins of life to, yes, the power of that volcano lurking beneath the ground. It was formed during the last three big events over the past 2.1 million years and is constantly monitored by the USGS (United States Geological Survey) for signs of anything out of the ordinary. That estimate changes as technology improves. Scientists can’t simply X-ray the Earth’s insides as they would a human’s bones or organs. Not every eruption at Yellowstone is a full-scale catastrophe, non-explosive eruptions of lava and less-violent events have occurred in and near the caldera since the last supereruption. The Yellowstone Caldera is one of nature’s most awesome creations and sits atop North America’s largest volcanic field. Yellowstone is one of the largest known volcanoes in the world and the largest volcanic system in North America.
