§Tsunami
watches and warnings are disseminated by PTWC to over 100 dissemination
points scattered throughout the Pacific Basin under the varying control
of the member states with general guidance from IOC, and the ICG/ITSU.
These major dissemination points are responsible for further
dissemination to hundreds of other points within their geographical
jurisdictions.
The major dissemination responsibility of the ITWS is the tsunami watch and/or warning.
§
§The
dissemination program is a sophisticated cooperative venture using
existing national and international communication facilities. The
communications systems to over 100 dissemination points along with over
100 data gathering stations are tested monthly with dummy messages. The
tests are monitored for minimum message travel times.
§
§These
dissemination points in turn disseminate to many more points in their
respective local areas.
