Supervolcanoes Trailer. Narrated by Benedict Cumberbatch.
Experience Earth as it was 250 million years ago - lush with vegetation and teeming with life on land and in the sea. Giant primordial reptiles roamed the forests and swamps, while invertebrates and fish inhabited vibrant coral reefs. Scientists now believe that a gigantic volcanic eruption across Siberian Russia laid waste to the rich diversity of the Permian Period. This global catastrophe claimed 70% of all plant and animal species in a time known as "the Great Dying."
Can a supervolcano erupt in our own time? Look no further than the fabled geyser fields of Yellowstone National Park. Deep below, a colossal dome of magma is building. It has exploded numerous times in the past, sending ash as far as Los Angeles. Supervolcanoes delivers audiences into the belly of this beast by reconstructing the landscape from thousands of high resolution images, then cutting away a section of the earth to reveal an image, derived from scientific data, of the fury building below the surface.
Earth does not have a monopoly on Supervolcanoes. In one of the program's most dramatic sequences, audiences will fly down onto the roiling surface of Jupiter's moon Io, to experience up close the largest volcano in our solar system: Loki. It likely formed when an impact blew a hole in Io's thin crust, and continually spews lava in towering columns that flood the landscape in a molten sea.
