What if Yellowstone ‘blows’? A look at the worst-case scenario
A Yellowstone supervolcano eruption would begin with weeks of warning signs, including earthquake swarms and ground uplift, culminating in a VEI 8 eruption with devastating ash fall, pyroclastic flows, and crippled infrastructure across North America. The eruption would devastate the US, particularly Denver, and threaten the global climate. The scenario would unfold with a series of immense volcanic eruptions.

Yellowstone Supervolcano Eruption Threatens US and Global Climate
A Yellowstone supervolcano eruption would begin with weeks of warning signs, including earthquake swarms and ground uplift, culminating in a VEI 8 eruption with devastating ash fall, pyroclastic flows, and crippled infrastructure across North America. The eruption would devastate the US, particularly Denver, and threaten the global climate. The scenario would unfold with a series of immense volcanic eruptions.
Why it matters
The Yellowstone supervolcano is a massive volcanic system located in Yellowstone National Park. A super-eruption occurred around 631,000 years ago, causing catastrophe in northwestern Wyoming and dispersing ash across much of North America. The effects were felt worldwide.
