In this episode host John Watt tackles the titans of Mother Nature - the earthquakes, tsunamis and volcanoes that have shaped the very bedrock of New Zealand. Through a series of intelligent interviews, explosive field-testing and gritty archival footage we see what science is doing to demystify our biggest natural phenomena. We'll be traveling the length and breadth of the country to discover exactly what the country's finest scientific minds are doing to help predict and prepare for the 'big one'. In doing so we meet geologists, palaeontologists and seismologists at the forefront of research into the most powerful forces of nature and the revolutionary measures being taken to minimize any potentially devastating fall out.
