2. In
2004
a
tsunami
in
the
Indian
Ocean
There
was
no
sea-­‐level
monitoring
instruments
in
the
Indian
Ocean
in
2004.
Many
countries
did
not
have
agencies
responsible
for
tsunami
warnings
or
points
of
contact
to
receive
messages
from
international
warning
centers.
The
United
Nations
Intergovernmental
Oceanographic
Commission
began
to
create
an
Ocean
tsunami
early
warning
system
after
the
2004
Indian
Ocean
tsunami.

3. Work
of
JAM
and
PTWC
When
an
earthquake
strikes
in
the
Indian
Ocean
region,
data
is
transmitted
to
the
Pacific
Tsunami
Warning
Centre
(PTWC)
and
Japan
Meteorological
Agency
(JAM).
They
have
responsibility
for
providing
the
Indian
Ocean
with
what
are
known
as
tsunami
watches.

4. Works
of
ADPC
ADCP
is
a
private
international
disaster
prevention
center
founded
in
Bangkok
in
1986.
ADCP
are
on
track
to
become
regional
watch
providers.
The
ADPC
has
been
coordinating
to
have
a
multi-­‐hazard
early
warning
system
(RIMES).
RIMES
will
work
alongside
the
national
and
regional
watch
providers
and
will
also
share
information
with
Hawaii
and
Japan.

5. Primary
responsibility
of
Hawaii
and
Japan
They
receive
earthquake
information
and
data
from
tidal
gauges
and
Deep-­‐ocean
Assessment
and
Reporting
of
Tsunamis
(DART)
sensors
or
buoys.
They
receive
news
bulletins,
telegrams,
and
information
over
the
telephone.
The
commission
for
the
Nuclear-­‐Test
Ban
Treaty
Organization
(CTBTO)
provide
data
from
seismographic
stations.
The
job
of
these
two
centres
is
to
locate
and
determine
the
size
of
earthquakes.
The
possibility
that
the
earthquake
causes
the
tsunami
decides
of
how.
The
attainment
time
of
the
tsunami
is
forecast.

6. When
the
two
centres
issue
watches
to
national
bodies
in
Indian
Ocean
It
is
the
responsibility
of
each
national
agency
to
alert
its
people.
26
out
of
28
Indian
Ocean
countries
have
focal
points
to
receive
tsunami
bulletins,
according
to
UNESCO.

7. Warnings
ways
to
the
population
Radio,
television,
SMS,
e-­‐mail,
bell
megaphone,
and
loudspeaker
are
used
as
a
transmission
ways.
In
the
some
countries,
well-­‐rehearsed
drills
is
done.

8. Warning
is
confused
by
the
difference
of
the
language.
In
the
place
where
the
infrastructure
is
poor,
it
is
difficult
to
transmit.
The
Tsunami
Warning
System
will
keep
upgrading
to
defend
our
body
in
the
future,
and
working.
