Résumé
Shockwave investigates the impending earthquake/tsunami predicted to hit the Pacific Northwest. The Cascadia Subduction Zone is a crack on the ocean floor that runs from California to British Columbia. It is nearly identical to the fault that ruptured off Sumatra in 2004, triggering a tsunami that killed more than 225,000 people. Five major cities (Vancouver, Victoria, Seattle, Portland and Sacramento) plus hundreds of small towns along a thousand kilometres of coastline will be heavily damaged. This documentary, detailed with state of the art computer animation, visits scientists who are creating new disaster survival plans based on what they have learned from the Sumatran disaster.
