Scientists Warn of Global Fallout from Potential Yellowstone Super-Eruption

Scientists Warn of Global Fallout from Potential Yellowstone Super-Eruption

Scientists said a future eruption of the Yellowstone super-volcano could generate massive ash fallout, cause a brief global cooling period and lead to widespread indirect fatalities, and they noted that extensive monitoring would likely provide early warning. Earlier modeling reported by The Conversation described possible seismic precursors and evacuation measures. A scenario outlined by FOX Weather, based on UK volcanic research, projected months-long disruptions to air travel, infrastructure, agriculture and global climate.

SciTechDaily added that widespread ashfall could disrupt infrastructure and agriculture and cause long-term climate and health effects. Westword noted that ash could affect Denver’s atmosphere, infrastructure and public health.
