Once it blows, how much of the southwest and The Great Plains states do you imagine would be left and able to grow crops? Think, at a minimum: debris cloud. What diameter do you imagine its super-caldera would eventually be?
TWO-PART ANSWER: Part 1
Many Americans grew concerned that a supereruption was looming after the New York Times detailed a project from a research team at Arizona State University. The team researched the events leading up to the last large eruption at Yellowstone. They found changes in the supervolcano’s system known to help trigger supereruptions, like magma flow, can develop faster than previously thought, according to the Times. “It’s shocking how little time is required to take a volcanic system from being quiet and sitting there to the edge of an eruption,” Hannah Shamloo, an ASU graduate student who was part of the research team, told the newspaper.
Many people mistakenly took that to mean Yellowstone’s supervolcano was overdue for a massive eruption. Christy Till, who was also part of the research team, later tweeted that the research team at no point suggested Yellowstone’s supervolcano was expected to erupt. “All signs of activity at Yellowstone are normal,” she wrote. “There are NO signs of eruption as some media outlets reporting.”
