Because of the limited data available on tsunamis, numerical methods are 

 commonly used to predict tsunami flooding of coastal areas. Finite-difference 

 equations are presented for simulating the propagation of tsunamis, but com- 

 puter programs are omitted because of the continuing work in progress and the 

 availability of up-to-date computer programs from other sources. Known mathe- 

 matical solutions, for tsunamis approaching the shoreline and tsunami-shoreline 

 interaction, are given to illustrate the effects of tsunamis and provide means 

 of verifying numerical results. The report discusses tsunami-structure inter- 

 action and illustrates various types of damage caused by tsunamis.
