Contents: This publication presents calculations of runup due to seismic sea 
waves (tsunamis) of 
equaled or exceeded 
combined effects of 
analysis as well as 
plete discussion of 
distant origin. The values given are interpreted as being 
on the average of once per 100 or once per 500 years. The 
astronomical tides and tsunamis are incorporated into the 
local resonance effects where judged significant. A com- 
the methodology is presented in Appendix A. 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 for the southern 
California communities and +75 percent for the Alaskan communities. It is 
essential that these runup predictions be reviewed approximately every 5 years 
in the light of advancements in the theory of tsunami generation, propagation, 
and runup.
