A geologic history of earthquakes at the Cascadia subduction zone.

Scientific reportage on what we know and don’t know about the mega-earthquake predicted to hit the Pacific Northwest Scientists have identified Seattle, Portland, and Vancouver as the urban centers of what will be the biggest earthquake—the Really Big One—in the continental United States. A quake will happen—in fact, it’s actually overdue. The Cascadia subduction zone is 750 miles long, running along the Pacific coast from Northern California up to southern British Columbia. In this fascinating book, The Seattle Times science reporter Sandi Doughton introduces readers to the scientists who are dedicated to understanding the way the earth moves and describes what patterns can be identified and how prepared (or not) people are. With a 100% chance of a mega-quake hitting the Pacific Northwest, this fascinating book reports on the scientists who are trying to understand when, where, and just how big The Big One will be.

Chap. 1 sets forth the general require. for applying the analysis & design provisions contained in Chap. 2 through 12 of the Nat. Earthquake Hazards Reduction Prog.
