KW - Winchester Bay VL - 72 IS - 2 N1 - All who live on the West Coast of the United States should be aware of the possibility of a major earthquake occurring. But what if only a part of the subduction zone ruptures? This article examines a possible rupture in the southern half of the Cascadia Subduction Zone (south of Alsea Bay, Oregon). The authors ask important questions. How quickly does tsunami wave height decline north of the southern rupture areas? How much time do communities north of the southern rupture areas have to evacuate before the first inundation and the largest inundation occur? How far north of the southern rupture areas will felt shaking likely trigger evacuation of a populace trained to evacuate for a local earthquake? (p.851) The authors address these questions using a 10,000-year record of offshore turbedite deposits and a ~4,600-year record of tsunami deposits at Bradley Lake. ER -
