Geologist Freysteinn Sigmundsson and his team descend into the crater of a dormant volcano to find out, in this video from NOVA: Doomsday Volcanoes. Experience the sights inside a volcanic chamber and learn how clues from fissures within help scientists piece together the story of how Iceland’s potent volcanoes are connected.
