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?

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.
