1. How tsunami warning
system is developed

2. Introductory
In 2004, the Indian Ocean tsunami killed about
230,000 people. To save people from tsunamis,
how early warning system for tsunamis is
developed.

3. A step for tsunamis
●Before 2004, the Indian Ocean and many
countries didn't have instruments that monitor
sea-level.
● Thus, there were no agencies that receive
tsunami warning from international warning
centers.

4. Tsunami watches
● By 2011, Regional Tsunami Watch Providers in
Indian Ocean countries take over tsunami
watches.
● The Pacific Tsunami Warning Center and the
Japan Meteorological Agency are responsible that
they provide tsunami watches for the Indian
Ocean.

5. Regional Integrated Multi-Hazard
Early Warning System
● RIMES will work early next year.
●Two centers in Hawaii and Japan receive
earthquake data from a range of tide and Deep-
ocean Assessment and Reporting of tsunamis
sensors.
●The commission for the Nuclear-Test Ban Treaty
Organization also receive earthquake data from
seismographic stations.

6. How two centers work
●The job of two centers is that decide the size of
earthquakes and predict whether the potential to
occur tsunamis.
● Whether that tsunamis occur depend on the
location and nature of earthquakes.

7. How the data about earthquakes
is informed
●The data that two centers received is given
national agencies.
● Warnings that tsunamis will occur are delivered
in a variety of ways, such as radio, television,
email, megaphones, and so on.

8. Conclusion
● These technology dose not always reach all over
the world.
● If warning reach, there are not the the way of
that people escape from tsunamis in poor.
