KW  - Volcanic activity prediction
N2  - Looks at ways and means volcanologists predict volcanic eruptions. Watch as they put those theories to the test at the summit of smoldering Mount Tungurahua in Ecuador. It's a high-stakes game of man versus the mountain; because if any of these theories prove correct, they could help forecast future volcanic activity and save lives all over the planet.
