*  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.  

In  2004  a  tsunami  in  the  Indian  Ocean�

*  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.�

Work  of  JAM  and  PTWC �

 *  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.  

Works  of  ADPC �

*  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.  

Primary  responsibility  of  Hawaii  and  Japan �

*  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.  

 

When  the  two  centres    issue  watches  to  national  bodies  in  Indian  Ocean�

*  Radio,  television,  SMS,  e-­‐mail,  bell  megaphone,  and  loudspeaker  are  used  as  a  transmission  ways.  

 *  In  the  some  countries,    well-­‐rehearsed  drills  is  done.  

Warnings  ways  to  the  population�

*  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.
