Tsunami Communication Plan
Tsunami Communication Plan : The primary purpose of the Communication Plan for the Tsunami Warning System is to serve as the communications operating manual for the Pacific Tsunami Warning Center (PTWC) and for participants of the Tsunami Warning System (TWS) of the Pacific. The Plan lists each country's tidal and seismological stations with preferred methods of communications between those stations and the Pacific Tsunami Warning Center. The Plan also lists the dissemination agencies in each country which receive tsunami watch and warning bulletins and communications methods by which the bulletins are sent from PTWC to those agencies.A secondary purpose of the Communication Plan is to provide a general overview of the operational procedures of the Tsunami Warning System and of the nature of tsunamis. The Plan discusses the general nature of tsunamis, the operation of the Tsunami Warning System, the communication methods and procedures for data acquisition from seismological and tidal stations, and the dissemination of information to participating agencies. Finally the Plan discusses the U.S., Alaska and West Coast Regional Warning System, giving criteria under which Watches and Warnings are issued and the recipients of those messages
