Volcano Live! S01E01 - Our Active World

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 edge of thesummit crater and the Halema'uma'u lava lake. Kate also travels to Iceland to visit Eyjafyallajokull, the volcano which caused air traffic chaos in 2010, and comedian Ed Byrne heads to Bristol university to work out why different volcanoes erupt in different ways.
