The document discusses the tsunami warning system in the Indian Ocean. It describes the old system, which lacked coordination between countries. This led to disasters like the 2004 Indian Ocean tsunami that killed over 230,000 people. Now, two main warning centers - the Pacific Tsunami Warning Center and Japan Meteorological Agency - work together to quickly analyze earthquakes and predict potential tsunamis. They use seismic and sea level monitoring instruments and communication networks to alert countries via radio, TV, internet, sirens and alarms.

2. Old Tsunami Warning System
● The organizations such as PWTC, JMA have
already existed.
● But there was not organizations responsible for
tsunami warning system.
● And the instruments for monitoring the sea-
level were not arranged enough.
● And the counties didn't communicate and
exchange information fully.
● Therefor, serious accident like India Ocean
tsunami happened.
3. About effects of the Indian Ocean
Tsunami
● This tsunami happened in 2004 and killed
about 230,000 people.
● For this reason, PWTC put the more sea-level
monitoring instruments .
● There are the better each other countries
communication and sharing the information.
● This becomes a large network of tsunami
warning system.
4. Two Major Tsunami Warning Center
And Their Jobs 1
● There are two major tsunami warning center.
One is PWTC introduced previous slide.
Another is Japan Meteorological Agency(JMA).
● They have two major jobs.
● One is to determine the size of earthquakes.
● Two is to predict how long tsunami strikes the
regions.
● It takes about 20 minutes to analyze the
earthquake.
5. Two Major Tsunami Warning Center
And Their Jobs 2
● And they receive the information of earthquake.
There is a great communication network.
● Many countries have the facilities of
earthquake. They send the seismic information
they take to PWT and JMA. Finally, This
information is sent and received around the
world.
6. About Pacific Tsunami Warning
Center In Detail
● It is alerting countries
to come the tsunami.
● Using the instruments
, it can predict
whether tsunami
happens or not.
● It has been alerting
for over 40 years.
● The picture is how
PWTC warns the
tsunami.
7. The Ways of Alerting The Region
● The information is sent and exchanged by
various ways.
● Indirectly, Warning of tsunami is sent out
through a radio, TV and Internet.
● Directly, we use a bell, amplification equipment
in the region which has possible of striking
tsunami
