Around 65 million years ago, a massive asteroid crashed into Mexico's Yucatan Peninsula. Nearly 75% of all life on earth vanished. But could a single asteroid have been the lone killer? Theories about what happened after the impact have been speculated on by the entire scientific community. Ranging from global warming to lethal worldwide firestorms, ideas have been put forth, but none have been proven. Then in 1995 a new theory claimed that a powerful mega-storm known as a hypercane caused the extinction. The hypercane allegedly reaches 20 miles into the stratosphere and has wind speeds of up to 500 miles per hour. 3-D computer graphics will reveal how this storm could have brought down nearly all life on the planet.

The largest volcanic eruption of the past two million years occurred on the Indonesian island of Sumatra some 75,000 years ago. The impact from the supervolcano Mount Toba decimated the local habitat, but gas, ash and debris from Toba made their way around the planet and formed a shield in the atmosphere that deflected the sun's warming rays. Temperatures plummeted and the planet was thrown into a volcanic winter and may have even pushed the planet into an ice age. 3-D computer animation will recreate the storm and unveil how this one volcano could have brought humanity to the edge of extinction.

Modern dams are marvels of engineering but after decades of neglect the U.S. infrastructure is in crisis and by 2020, 85% of U.S. dams may be near their breaking point. When the South Fork Dam near Johnstown, Pennsylvania gave way in a storm in 1889, killing 2200 people, it was the worst disaster in U.S. history. Today, with millions of Americans living nearby massive dams, the result of a failure could be catastrophic.

The U.S. Department of Energy and the Nuclear Regulatory Commission plan to transport 77,000 tons of nuclear waste to a permanent storage facility 950 feet below Nevada's Yucca Mountain. If the plan goes through, much of the cargo will travel through Las Vegas, making an accident there a very disturbing possibility. If history has taught us anything, it's that transporting dangerous goods can sometimes have catastrophic results. Take a look at the potential disaster that such a rail accident would have in Las Vegas.

Anthrax is the most feared of all the biological weapons--spores entering the body through the lungs are lethal. In 2001, a simple letter, sent through the US mail, paralyzed a nation, when anthrax spores were found inside. Experts predict that anthrax released over a populated area would result in unprecedented loss of life--a few pounds of anthrax released under the right conditions could kill hundreds of thousands of people. Will anthrax be used to create a worldwide disaster?
