One of the most powerful supervolcanoes on Earth is found in the American northwest — Yellowstone. It has the largest magma reservoir on Earth, and its geothermal and seismic activity has been constantly evolving for the last 10 years. What if that activity were the first indication of the volcano’s great reawakening? And if Yellowstone erupts, what would be the consequences for humanity? This 52-minute documentary will take you through different possible scenarios of a Yellowstone super eruption using impressive 3D models and the help of leading experts in the field.
