What if Yellowstone erupts? What would happen to the US and the world

The prospect of a supervolcano eruption at Yellowstone National Park heralds dire consequences on multiple fronts.

Experts predict detectable signs, such as seismic activity and ground shifts, prior to any eruption event.

This would necessitate evacuations for nearly 200,000 individuals, both locals and tourists, leading to significant turmoil.

An ash cloud would ensue, disrupting transport and agricultural sectors for considerable periods.
