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.
