End Days - Super Volcanoes

This scenario is based on the supervolcano beneath Yellowstone National Park erupting, causing vast damage to the area 100 km around the volcano, as well as releasing ash into the atmosphere which cooled the earth. This segment has only aired in the UK. This scenario was explored in depth in another BBC docudrama, Supervolcano. See Yellowstone Caldera. YouTube - End Days - Super Volcanoes
