Episode 2

Kate Humble and Professor Iain Stewart present a four day journey into our extraordinary and dynamic planet, live from Kilauea on Hawaii, the world's most active volcano. They broadcast from the site of the 1969 Mauna Ulu eruption which saw more than 17 square miles of lush rainforest covered in lava. Kate also travels to Iceland to the island of Heimeay where a village of fishermen fought a volcano - and won. And volcanologist Hugh Tuffen sends back a video diary of his expedition to Mount Puyehue in Chile.
