The two-part A Volcano Odyssey discovers how a lava gush flooded an area as large as France, partially caused the demise of dinosaurs but also helped the emergence of mammals and new life forms.
These geological regions known as large igneous provinces (LIPs) can appear anywhere and cause massive havoc for life.
These LIPs have since been identified near Iceland, but also in the USA and Germany where they emerged as recently as 10,000 years ago and poisoned the atmosphere. Still active, what do these deadly volcanoes have in store for us next?
