  • 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.  
  • 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.
  • 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.  
  • 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.  
  • 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.    
  • 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.  
  •   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.
