episode description
They can turn bright blue skies dark as the night. They can, in an instant, make entire cities disappear. They can crush the human spirit with unflinching indifference. They are natural disasters — unforgiving forces of nature that bend steel, smash concrete and rip human bodies to shreds. Rampaging floods. Roiling Oceans. Boiling mountains of lava — the beauty of nature can turn on a dime, creating some of the most horrific events ever recorded in human history. Names like Vesuvius, Galveston, Johnstown are tragic reminders of a unbridled power unleashed without warning — destructive forces that can catch even the most wary souls off guard, wiping them from the face of the Earth. These monstrous spectacles are at once mesmerizing and haunting. The visual record left in their wake is like none other. Now using restored film footage and high-definition photos, we can dig deep beneath the madness — and the rubble — to explore what happens to cities, towns and people… when mother nature decides to let loose.
