2. About Tsunami early warning
system
Tsunami early warning system is the system that
alert people living near the coastline of Tsunami
being coming.
We can escape from Tsunami because this
system alert us that Tsunami is coming.

3. How the system works 1
The Pacific Tsunami Warning Centre (PTWC)
receive earthquake information and data from tidal
gauges and Deep-ocean Assessment and
Reporting of Tsunamis (DART) sensors or buoys.

4. How the system works 2
These two centres determine the size of
earthquakes, determine whether they have the
potential to produce tsunamis and predict tsunami
wave arrival times wherever possible.

5. How the system works 3
They judge the Inland earthquakes will not cause
tsunamis and not all underwater earthquakes
cause tsunamis. This depends on the location and
nature of the earthquake.

6. How the system works 4
The two centres issue watches, if necessary, to
national bodies in the Indian Ocean and it is the
responsibility of each national agency to alert its
population, by whatever means.

7. How the system works 5
Warnings to the population are delivered in a
variety of ways. Over the airwaves - radio,
television, SMS, email - and manually, using bells,
megaphones or loud-speakers attached to
mosques. In some countries, well-rehearsed drills
will kick in and local agencies will coordinate an
evacuation.

8. Conclusion
Thanks for this system, many people can escape
from this Tsunami, but In other areas, there are no
escape routes as transport infrastructure is poor.
