In this explosive episode, we find out how geology, chemistry, physics and even creativity go into understanding volcanoes. We learn volcanoes are different ages and sizes and also have labels such as active, dormant and extinct, and cone, shield and composite. Kai and Anostin travel to Iceland - the land of fire and ice! They meet Volcanologist Dr. Rikke Pedersen who explains the volcanology of Iceland and the differences between the types of eruptions. The Hawaiian islands were also created from volcanoes. We talk with Indigenous Hawaiian geophysicist Dr. Jim Kauahikaua who studies volcanic activity in Hawaii, drawing from science, story and history. Commander John Herrington explains how volcanoes are one of the most powerful forces of nature. Kai shows us his rockin’ volcanorock collection, while the Cosmic Surfer visits some famous volcanoes.
