Cascadia’s Fault: The Coming Earthquake and Tsunami that Could Devastate North America

Includes a new Afterword by the author on the 2011 Japan Earthquake, the lessons learned, and the parallel threat to North America. A new study just published by the US Geological Survey confirms and underlines many of the issued raised in the first edition of Cascadia’s Fault.

There is a crack in the earth’s crust that runs roughly 31 miles offshore, approximately 683 miles from Northern California up through Vancouver Island off the coast of British Columbia. The Cascadia Subduction Zone has generated massive earthquakes over and over again throughout geologic time–at least thirty-six major events in the last 10,000 years. This fault generates a monster earthquake about every 500 years. And the monster is due to return at any time. It could happen 200 years from now, or it could be tonight.

The Cascadia Subduction Zone is virtually identical to the offshore fault that wrecked Sumatra in 2004. It will generate the same earthquake we saw in Sumatra, at magnitude nine or higher, sending crippling shockwaves across a far wider area than any California quake. Slamming into Sacramento, Portland, Seattle, Victoria, and Vancouver, it will send tidal waves to the shores of Australia, New Zealand, and Japan, damaging the economies of the Pacific Rim countries and their trading partners for years to come.

In light of recent massive quakes in Haiti, Chile, Mexico — and Japan — Cascadia’s Fault not only tells the story of this potentially devastating earthquake and the tsunamis it will spawn, it also warns us about an impending crisis almost unprecedented in modern history.
