Since 1976, the Dead Sea's level has dropped more than 100 feet, leaving its coastline pockmarked with thousands of sinkholes. NOVA follows the unprecedented endeavor to connect the Red Sea to the Dead Sea by way of a massive desalination plant - perhaps the world's largest water chemistry experiment - as scientists race to save the Dead Sea and bring water to one of the driest regions on Earth.

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.
