  1. Developing a Global Tsunami Warningand Mitigation System:From Commitment to Action EWC-III, Scientific and Technical SymposiumBonn, 28 March 2006UNESCAP Thailand Trust Fund BriefingBangkok, 28 March 2006 Patricio A.

  2. A Call to Action … 26 December 2004250,000 dead, 500,000 injured 1 million displaced $8 billion in damages “We cannot stop natural calamities, but we can and must better equip individuals and communities to withstand them.”UN Secretary-General Kofi Annan

  3. Plate Tectonics Active subducting plate boundaries

  4. IOC ICG/PTWS • 1965 - response to 1960 Pacific-wide Chile tsunami IOC established ICG/ITSU (now ICG/PTWS) Intergovernmental Coordination Group for the Pacific Tsunami Warning and Mitigation System • successful & operational Tsunami Warning and Mitigation System • PTWC - Operational HQ • ITIC - Oversee and monitor effectiveness, Facilitate to establish new systems, preparedness, outreach

  5. IOC ICG/PTWS 28 member States (2005): Australia, Canada, Chile, China, Colombia, Cook Islands, Costa Rica, Democratic People's Republic of Korea, Ecuador, El Salvador, Fiji, France, Guatemala, Indonesia, Japan, Mexico, New Zealand, Nicaragua, Peru, Philippines, Republic of Korea, Russian Federation, Singapore, Thailand, United States, Samoa, Vietnam. • Successful Operational Tsunami Warning System > 40 yrs • Successful international scientific program • Pacific Basin monitoring of seismicity and sea levels • Direct humanitarian aim • Mitigate tsunami effects - save lives/property

  6. PTWC Global Seismic Network

  7. March & April 2005: Considering the devastating tsunami on Dec 26th 2004, two International Coordination meetings on the Development of an IO TWS took place in Paris and Mauritius

  8. Time schedule and milestones in 2005 Implementation Interim System IOC-JMA-PTWC 16 National Assessment Missions WMO/ISDR/IOC/ADRC/JMA/UNESCAP Sea level stations being deployed • March 3-8: UNESCO/IOC 1st Regional Technical Coordination Meeting, Paris • April 14-16: UNESCO/IOC 2nd Regional Coordination Meeting, Mauritius • June 21: IOC General Assembly, Paris: Formal establishment of ICG/IOTWS • August 3-5: ICG/IOTWS-I , Perth: focus on technical aspects • December 14-16: ICG/IOTWS-II, Hyderabad: recommendations & commitments

  9. Initial System for July 2006 • Based on Existing: • Network of 26 (of 29) National Information Centres [7/24] • Tsunami Focal Points [7/24] • Slowly evolving into a • Network of Tsunami Warning Centres in charge of • National Mitigation Plans (Assessment, Warning, Preparedness) • Need to develop Regional Instrumental Networks: • Improved Seismographic network (faster and more accurate detection of earthquakes through denser network, better real-time source characterization) • Real-time network of sea-level stations (faster detection of tsunamis through denser network)

  10. Operational Planned Core IOTWS Seismographic Network Agreed on Stations

  11. IOTWS: National Assessment and Plans

  12. The Challenge • We essentially know what is needed at the country level in 16 countries Work for rest of countries will be completed in 2006 (6 countries) • ICG is requesting a Comprehensive IOTWS Plan, including the Country level • Therefore, we need the development of the National Plans at the Country level.

  13. TSUNAMI Early Warning Overview • Hazard Risk Assessment • Warning Guidance • Mitigation - Preparedness Earthquake Tsunami National Government Local Government Tsunami Warning Center What is Tsunami? People Where is Evacuation Route? Mass Media International - Regional Framework National Warning System Public Awareness Cabinet Office Japan

  14. A perfect warning will be useless if people do not know what to do in case of an emergency Awareness and preparedness at the country level is essential

  15. :STAKEHOLDER COORDINATION

  16. June 21-30, 2005: the 23rd IOC General Assembly decided resolutions on the establishment of a global and three regional Intergovernmental Coordination Groups on TEWS (XXIII-12 to XXXIII-15) for -the Indian Ocean (ICG/IOTWS) - the Caribbean (ICG/CARTWS) - the NE Atlantic and Med (ICG/NEAMTWS)

  17. Three more regions to coordinate

  18. Intergovernmental Coordination Group meetings • 03-05 Aug 2005: ICG/IOTWS-I, Perth • 21-22 Nov 2005: ICG/NEAMTWS-I, Rome • 14-16 Dec 2005: ICG/IOTWS-II, Hyderabad • 10-12 Jan 2006: ICG/CARTWS-I, Barbados and to come: • May 2006: ICG/ITSU-XXI, Melbourne • May 2006: ICG/NEAMTWS-II, Nice • July/August 2006: ICG/IOTWS-III, Bali • Dec 2006: ICG/CARTWS-II, Venezuela

  19. Beyond immediate response: Multi-Hazard Platforms • Storm – surges (IOC, WMO, JCOMM) • Tropical storms (WMO, JCOMM) • Improving Storm and cyclones track forecasts (IOC, WMO, JCOMM) • Ice Hazard (IOC, WMO, JCOMM) • Oil Spills (IOC, WMO, UNEP)
