The question of when the last Yellowstone supervolcano eruption occurred is fundamental to understanding the volcano's behavior and assessing the potential risks it poses. The focus for scientists is on deciphering the complex signals from the volcano to better understand its plumbing system and improve long-term forecasts, ensuring that the primary risk from Yellowstone remains from localized hazards like hydrothermal explosions, rather than a civilization-ending super eruption.
