Take a look at the latest volcanic survey data and marvel at the frightening number of volcanoes heating up around the world. Is this a simple, geological coincidence, or the sign of some larger, potentially deadly pattern at work? Join one group of scientists as they reveal a number of cutting-edge theories to explain the sudden surge in volcanic activity . Then, 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.
