  1. Tsunami Warning and Mitigation SystemMasahiro YamamotoTsunami UnitIntergovernmental Oceanographic Commission (IOC)UNESCO

  2. IOC co-ordinates Tsunami Warning Systems as an end-to-end system Tsunami Early Warning System --effective utilization of existing systems--- O upstream detection, verification, tsunami forecast, dissemination of tsunami warning, intergovernmental O downstream delivery of warnings, initiate national counter-measures, prepare and implement standardized reaction

  3. 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

  4. Indian OceanWhere are we now? • All countries of the Indian Ocean participate • Interim Tsunami Advisory Information from centers in Hawaii and Tokyo • National 24/7 Tsunami Focal Point • Governance – UN/IOC through Intergovernmental Group (ICG/IOTWS)

  5. What is the System? The system must be: • Based on open and free data and information exchange • Based on international and multilateral cooperation • Effective utilization of existing infrastructure; seismic, sea level, communication

  6. オホーツク海沿岸 北海道日本海 沿岸北部 北海道太平洋沿岸東部 北海道日本海 沿岸南部 北海道太平洋 北海道太平洋沿岸中部 沿岸西部 青森県 太平洋沿岸 青森県日本海沿岸 陸奥湾 Major Tsunami 岩手県 Tsunami Tsunami Attention 宮城県 JMA Seismic Network Tidal Network Tsunami Warning Tsunami Forecast Operation for Tsunamis from nearby Origin Evaluation of Tsunami ・Quantitative Tsunami forecast (arrival time and Tsunami height) ・Tsunami warning for 66 regions Tsunami Database

  7. What we need for Tsunami Warning Occurrence of Earthquake Generation of Tsunami Components of tsunami warning system Detection of Seismic Wave Network of seismographs Real time data transmission Determination of Magnitude and Hypocenter Real time data processing system Evaluation of Tsunami Criteria for Tsunami grade Issuance of Tsunami Warning Communication facility to disseminate Tsunami Warning Detection of Tsunami Network of tide gauge to monitor tsunami Issuance of Tsunami Information Re-evaluation of Tsunami

  8. 3 DART-like systems deployed

  9. June 2005: IOC General Assembly decided resolutions on the establishment of a global and three regional Intergovernmental Coordination Groups on TEWS for -the Indian Ocean (ICG/IOTWS) - the Caribbean (ICG/CARTWS) - the NE Atlantic and Med (ICG/NEAMTWS)

  10. Three more regions to coordinate

  11. GLOBAL Tsunami Warning and Mitigation System 3 Oceans 4 Seas

  12. WG1/ICG/PTWS • Infrastructure of Seismic Network cooperation CTBTO, FDSN (real time) • Filling in the network gaps local tsunami/national system • New technologies for tsunami warning GPS, deep sea observation • Sharing operational techniques develop real-time operational system

  13. Next-Generation--Tsunami Warning System-- • Real time GPS processing system • Enhancement of real time analyzing system • Real time tsunami numerical modeling Strengthen cooperation between science communities and tsunami warning centers
