This episode focuses on the Asia-Pacific side of The Pacific Rim of Fire, which stands as a living testament to the beauty and danger that powerful geologic forces can deliver. The Pacific Rim is home to half of the world's active volcanoes and ninety percent of the world's earthquakes, yet nearly 800 million people continue to live within its violent edge. Our journey begins in New Zealand, a land of volcanoes and earthquakes, where we find a 500-kilometre long slip-strike fault deep under the Pacific Ocean. Geologist Hamish Campbell will take us to the crater of White Island, the country’s most active volcano. Then we'll visit the country's southern island with John Youngson, to find out how New Zealand’s longest fault-line contributes to the gold industry. Finally in Japan, viewers will hike up to Mount Fuji – the iconic peak where science and legend converge, getting up-close and personal with a fault-line witnessing firsthand what it’s like to discover new ways of monitoring, and hopefully one day predicting, seismic activity onboard the world’s most advanced drilling vessels.

A tsunami is a dramatic indicator of geological activity magnifying the impact into extensive coastal destruction. Scientists searching for evidence of past tsunamis to predict when they are likely to recur and how severe they are likely to be uncover a new phenomenon, the mega-tsunami.
