In the 6th century AD, large parts of the world were affected by mysterious weather events causing temperature drop, crop failures and famines. All this might be the result of a large volcanic eruption in the tropics. But can a local natural disaster impact the global weather, thus influencing the course of history? Using stunning re-enactments and unique animation techniques, "The Power of Volcanoes" makes it clear: Volcanoes might be sleeping giants. But they can wake up quicker than you think and in the worst case trigger a fatal chain of events.
