When the Siren Goes Part 3 - Volcanoes

Beginning with a remarkable recording of an eyewitness recalling the Mt Tarawera eruption of 1886, the programme looks at what would happen in Auckland if a volcano were to erupt. The conclusions of current research are set out, along with a scientific explanation of how and why eruptions occur. An Auckland primary school is visited to see how effective disaster planning is, and a volcanologist reflects on how New Zealanders would face the challenge of living off the land.
