Abstract : Calculations of runup due to seismic sea waves (tsunamis) of distant origin are made for 15 coastal communities within the state of California and 3 coastal communities within the state of Alaska. The values given are interpreted as being equaled or exceeded on the average of once per 100 or once per 500 years, whichever is indicated. The combined effects of astronomical tides and tsunamis are incorporated into the analysis as well as local resonance effects where judged significant. A complete discussion of the methodology is presented. It is essential that these runup predictions be reviewed approximately every five years in the light of advancements in the theory of tsunami generation, propagation, and runup.
