the deep ocean. If this can be achieved, a subsequent 

 development of a real-time reporting system would greatly 

 improve the capabilities of the international Tsunami Warn- 

 ing System. The existing system (Figure iS), with head- 

 quarters at the NOAA Honolulu Observatory, uses an array of 

 seismographs around the Pacific to report earthquake data. 

 Using a very high priority on all available communication 

 systems, the location of an epicenter for a large earthquake 

 is ordinarily computed in less than an hour after the event.
