450 million years ago, nearly all life on Earth was eliminated. Could this mass extinction have been caused by rays from outer space? And it could happen again?!

  • Stunning computer graphics and actual footage combine to create convincing pictures of the risks faced by U.S. cities.
  • MEGA DISASTERS explores the worst of what could happen.
  • A ten-second gamma ray burst could trigger a slow and miserable planetary death.


It has happened before, and it could happen again. What makes storms, earthquakes and other events into natural disasters is not how they occur, but where they strike. MEGA DISASTERS asks the "what ifs?" no one ever wants to face. A masterful blend of actual footage, computer graphics and interviews with leading scientists and public safety experts explores the outer limits of what could happen if everything went wrong.

Gamma ray bursts occur randomly and often. At times, they light up the reaches of deep space like fireworks. Just ten seconds' exposure to one would spell doom for Earth.

And scientists at the University of Kansas believe such a thing may have happened 450 million years ago. The resulting destruction of the ozone layer and chemical smog might explain the mass extinction that ended the Ordovician Period. If it occurred once, what's to stop it from happening again? And what would be the result if such a devastating event happened today?

In intricate detail and with compelling graphics, MEGA DISASTERS examines the terrifying possibility of another gamma ray burst. Food chains would collapse, leading to worldwide famine. An electromagnetic pulse would disable our electronics, returning us to the Stone Age. Scientists predict the Earth could support only 5 to 10 percent of its current population, leaving nearly 6 billion people to die, most by starvation.

You'll never gaze at the stars the same way again after seeing MEGA DISASTERS: GAMMA RAY BURST!
