be included in the ship-of-opportunity pro- 

 gram. Additional instrumentation should 

 be placed on offshore platforms. 



Another iiiea for immediate improvement 

 is in tlie Tsnnami "Warning System. The 

 present ability to forecast tsunami arrival 

 times at Pacific Ocean locations appeare to 

 be adequate, but run-up forecasts often are 

 grossly in error. The Tsunami Warning Sys- 

 tem performance is limited by lack of suffi- 

 cient nearshore, deep ocean tidal, and seismic 

 information as well as inadequate theoretical 

 understanding of energy- focusing processes. 

 Additional instrumentation is required in the 

 Pacific, possibly at island stations, and fur-, 

 ther development of deep ocean tidal instru- 

 mentation is needed. 



World Merchant Ship Density, June 12, 1964 



The Commission recommends that the 

 National Oceanic and Atmospheric 

 Agency (ESSA) expand the tide and seis- 

 mic monitoring network in the Pacific 

 basin. International communications from 

 South America and the Southwest Pacific 

 should be improved. Additional research 

 on tsunami generation and run-up prob- 

 lems should be instituted. 



Improvements in our capability to fore- 

 cast hurricane development and motion and 

 the storm surge are urgently required. 



Xavy, Air Force, and ESSA aircraft 

 should be augmented by additional high per- 

 formance aircraft with up-to-date instrumen- 

 tation. In addition, there is a continuing oper-
