Yellowstone supervolcano eruption simulation models global catastrophe

Researchers have published a detailed scientific thought experiment modeling the hypothetical consequences of a Yellowstone super-eruption. Experts emphasize that this is a mathematical simulation and not a prediction of imminent activity, noting that the caldera is not considered overdue for an eruption.

The model outlines a potential two-month escalation period, beginning with unusual earthquake swarms and ground uplift detectable by seismometers and GPS stations. This progression would likely trigger rising volcanic alert levels and eventual mass evacuations for approximately 200,000 residents within a 100-kilometer zone.

In the event of an eruption, the simulation projects catastrophic impacts, including massive ash clouds that could blanket North America, disrupt power grids, and cause significant infrastructure collapse. The long-term global consequences modeled include a drop in average temperatures by approximately 32 degrees Fahrenheit and potential famine, which researchers estimate could lead to up to 1.3 billion premature deaths worldwide.
