POMPEII: THE DOOMED CITY from HISTORYr, looks at one of the world's most devastating natural disasters and projects  what would happen if Mt. Vesuvius erupted again today. Many scientists believe we are playing with fire and that Vesuvius  will erupt soon, and they question how the now three million residents could escape. In 79 AD, Vesuvius exploded, burying  the city of Pompeii and other Roman towns along the Bay of Naples beneath layers of ash and pumice, killing thousands.  DIGGING FOR THE TRUTH's Josh Bernstein visits the Bay of Naples and finds the entire location is built on ancient volcanic  rock, some of it still steaming. He even climbs Mt. Stromboli, on an island near Sicily, where "fireworks" from the mountain are  considered nightly entertainment. Actual footage, interviews with scientists and public safety experts, along with stunning  computer graphics map out the realities of another eruption.
