What does it take for a volcanic eruption to really shake the world?
Geologists say that the Yellowstone Supervolcano is 20,000 years past due for a major eruption. But no one knows whether it will happen tomorrow or thousands of years from now. This hidden volcano has the power to kill millions of people, plunge the world’sclimate into volcanic winter and render large portions of North America uninhabitable. We follow the scientists as they track seismic changes and plan for the unthinkable.
