NotesAttempts to estimate potential flooding and beach retreat following subsidence from a great earthquake. Uses geological record of paleoearthquakes. "The larger bays of southern Washington and northwest Oregon demonstrate the greatest potential hazard for regional post-seismic flooding of coastal lowlands. Specifically, dikes constructed to 100-year flood levels could be overtopped annually, following coseismic subsidence of 1-2 m." (p.266)
