How Supervolcanoes Work

In this episode, Josh and Chuck dive deep into supervolcanoes—those catastrophically powerful geological events that are way scarier than your average volcano. They break down what makes a supervolcano different from a regular volcano, explore past eruptions like the massive Toba explosion 74,000 years ago that nearly wiped out humanity, and dig into what's lurking beneath Yellowstone, where an absolutely enormous magma chamber sits poised and pressurized beneath the earth. While the hosts reassure listeners that the odds of Yellowstone blowing in any given year are incredibly slim, they make it clear that when these things do go off, they can literally change global climate, bury entire regions under hundreds of feet of ash, and trigger an ice age—all of which is genuinely terrifying to contemplate.
