Type 16 Flood Insurance Study: Tsunami Predictions for Monterey and San Francisco Bays and Puget Sound

Garcia, Andrew W. / Houston, James Robert

Calculations of runup due to seismic sea waves (tsunamis) of distant origin were made for Monterey and San Francisco Bays and the greater part of Puget Sound. Those areas which are specifically included and excluded are listed. The values presented are interpreted as being equaled or exceeded on the average of once per 100 (R??????) or once per 500 (R??????) yr, whichever is indicated. All runup values, R?????? and R??????, are referenced to the mean sea level datum. The combined effects of astronomical tides and tsunamis are incorporated into the analysis as are certain local effects. The effects of wind waves superimposed on the tsunami have been neglected. The simultaneous occurrence of a storm surge and tsunami is considered highly improbable and therefore unlikely to constitute a 1 in 100- or 1 in 500-yr event. Analysis of the error attributed to each of the various steps in the procedure results in an estimated maximum average error of about ±40 percent._x000D_ _x000D_ NOTE: This file is large.
