Professor Iain Stewart examines the powerful geological forces that unleashed the devastating Japanese earthquake, and explores how the release of this power of the planet brought Japan to the brink of a nuclear meltdown.

He follows moment by moment how the earthquake was generated under the Pacific Ocean, travelled to the Japanese mainland, and the rare conditions that unleashed a tsunami.

He also reveals the latest science behind earthquakes - from why we can't predict them, to what causes some of them to reach such power.

Iain shows why our civilisation has developed such a dangerous relationship with earthquakes, and why millions of us continue to live in earthquake zones across the world. Show less
