One of nature's most spectacular and perilous wonders, volcanoes are capable of cataclysmically consuming entire forests or towns and triggering tsunamis, flash floods, earthquakes, mudflows and rock falls. Of hundreds of active volcanoes in the world, over three-quarters are part of the explosive Ring of Fire. Explore this fiery and earthquake-prone region of the Pacific Ocean -- from the U.S. to Japan and beyond -- to learn the causes of eruptions and how 500 million people have adapted to --even embraced -- living in their volatile shadow ... from miners in Chile eking out a perilous living from the sulphur produced in the heart of active volcanoes to macaques monkeys luxuriating in naturally formed hot mineral springs in Japan's remote "Hell Valley."
