Take an in-depth look at some of nature's most terrifying scenarios in this 3-disc DVD set examining six possible catastrophes that could result in unprecedented destruction. Learn how cities such as Dallas could be reduced to rubble within minutes and why London may be poised for a flood of New Orleans proportions. From a mega-sized tornado measuring two miles across, to a solar wind that could cause a worldwide blackout, understand the science behind mega-disasters, why they happen and whether you're at risk for a major event.

Super Tornado
With wind speeds exceeding 350 mph, a two mile wide super tornado would reduce downtown Dallas to a war zone within minutes. When it does, a Dallas emergency city manager is forced to choose between his family's safety and saving the lives of millions.

Solar Storm
Beneath the boiling surface of the sun lies a force that could destroy crucial technology and electrical grids – throwing the modern world back to the Stone Age. With only hours to prepare, a New York City engineer struggles to convince the mayor to take immediate action to save an entire country.

Super Typhoon
So far, the 7 million inhabitants of Hong Kong have escaped a direct hit by the Pacific's powerful hurricanes. However, a slight change in weather sends an emergency coordinator scurrying through the streets to make sure her city is safe as a super typhoon eyes the island.

Mega Flood
We saw what happened to New Orleans after the sea breached its levies. But, could the same thing happen to London? The city is well protected against the power of a storm surge, but there is one weakness, floods.

Fire Storm
The Australian city of Sydney faces the threat of an unstoppable wildfire every year. For the men and women working at the forefront of fire science, the nightmare is about to begin.

Ice Storm
More than a decade ago, an ice storm brought the Canadian city of Montreal to its knees. Scientists now believe there is far worse to come. Learn how the big freeze began with a warm spell.
