2. How the Tsunami Warning System
1: The need for tsunami warning system
PTWC (Pacific Ocean Tsunami Warning Center) was
inaugurated 40 years ago is now. 2004 Indian Ocean tsunami
and issued a death about 230,000 people. Since then, the
Intergovernmental Oceanographic Commission of the United
States has been trying to better things than ever in the Indian
Ocean tsunami warning system.
Not only between countries in the region can communicate,
share information is now more than ever. As a result,
information technology and can now also able to secure in
2004.
3. 2: How the Tsunami Warning System
Occurs around the Indian Ocean earthquake
Japan Meteorological Agency(JMA) in Tokyo and Hawaii
Earthquake Information was sent to the data of earthquake.
The data of earthquake was sent from JMA and Hawaii to
PTWC
The information is sent to countries such as the vigilance level
around the Indian Ocean.
4. What PTWC?
Go to the official: Pacific Ocean Tsunami Warning Center
Founded: 1949
Country Operations: National Oceanic and
Atmospheric Administration (NOAA)
Objective: To predict the future of the Tsunami.
To issue a tsunami warning in the Pacific
Ocean region a dangerous area when
deemed necessary.
5. The tsunami detection from deep-sea
● National Oceanic and Atmospheric Administration
(NOAA) has since 1995 and developed Deep-
ocean Assessment and Reporting of Tsunamis
(DART) system in 2001, was established six DART
stations in the Pacific Ocean.
● This is due to the Sumatra earthquake in 2004,
was developed from a heightened awareness of
the DART tsunami crisis in the world.
6. Far from the coast when the tsunami?
Far from shore when the tsunami, the DART station sent to
detailed information about tsunami to the PTWC. So there are
a number of DART station. Thus, DART was to detect the
passage of a tsunami, sending data to the PTWC tsunami.
From this system, improved significantly in the Pacific Ocean
tsunami warning and tsunami warning.
7. The way to warning
The way
Use to the radio breaking news, radio,
television, SMS,
e-mail
Manual Bell, megaphone,
loudspeaker
8. Conclusion
● Countries that around the Indian Ocean effect a lot of
damage by tsunami.So people should have know about
tsunami and this action.
● I think it's important to have a sense of crisis tsunami for all
people who live country
.
● Nobody know when a tsunami happens, I need to know and
evacuation routes.
