Dear Dr. Hulman:

Enclosed is the final report comparing tsunami run-up estimates from a numerical time-stepping technique with the ray tracing method l

used by Dr. Wilson. Note in Figures 3 and 4 the relatively greater variability in run-up as compared to what one would derive from Dr. Wilson's study. This is, as we indicated in past discussions, both expected and more realistic in that tsunamis do show considerable variability in run-up from point-to-point.

In terms of the local tsunami potential, these results do not conflict with the figure of 15.6 ft, from MLLW derived in Dr. Wilson's l

report.

{

\\

With the availability of the time-stepping programs for both d

local (asusedforSanOnofre)andPacific-widetsunamis,Ibelieve that in the future we can produce results which will convince the most conservative critic.

Sincerely,

-j 1
