Watch Digging for the Truth online: Episode 3 Pompeii Secrets Revealed

In 79 AD, the volcano Vesuvius exploded in one of history's deadliest eruptions, burying the city of Pompeii and other Roman towns along the Bay of Naples beneath layers of ash and pumice. Pompeii was rediscovered in the 18th century, but only recently have archaeologists and volcanologists come to understand exactly how the eruption unfolded, and why it took the people of Pompeii almost entirely by surprise. Intrigued, host Josh Bernstein visits the Bay of Naples, and learns the entire area is built on ancient volcanic rock, some of it still steaming. He climbs the world's most active volcano--Stromboli--an island near Sicily, where ""fireworks"" from the mountain are a nightly entertainment. Back at Pompeii, he searches for clues that might have enlightened the Romans to the growing threat in their midst. And he literally plays with fire as he follows the story right into the heart of Vesuvius.
