"Fault Line" is the eighth episode of Thunderbirds 2086, and fifth produced overall. The episode first aired in Japan on May 15, 1982.


U.E. Plant #1, the world's first underwater commercial thermoelectric power plant, is built directly over the Maui fault line near Hawaii. Progress goes well, until Edward Frontosa heads down to illegally mine for a mysterious substance. His greed results in the fault going unstable, and threatens to destroy the entire power plant.
