  2. TOPICS • Tsunami Monitoring System in Indian Ocean and in South east Asia • Indonesian Tsunami Early Warning System (InaTEWS) • Goal of InaTEWS and requirement • Current Status of the monitoring system • Future plan

  3. IOTWS and SCMG of ASEAN • IOTWS = Indian Ocean Tsunami Warning System • WG-1, Seismic Measurements, Data Collection, And Exchange • WG-2, Sea Level Data, Deep-ocean measurement And Exchange • WG-3, Risk Assessment • WG-4, Modeling, Forecasting And Scenario Development • WG-5, The System Of Interoperable Advisory And Warning Centres • WG-6, Mitigation, Preparedness And Response • SCMG= Sub Committee on Meteorology and Geophysics • Technical Task Force for establishing national tsunami center in ASEAN countries • AEIC = ASEAN Earthquake Information Center • To rapidly disseminate information on earthquakes and their associated events occurring in various parts of ASEAN countries to authorities and public. • Hosted by BMG of Indonesia

  4. Terms of Reference of WG – 1 of IOTWS • Identify the core seismic stations in Indian Ocean region • Establish the core seismic network in Indian Ocean region • Make seismic data of core seismic station available to member state countries in real time for tsunami warning purposes. • Establish the communication link to the members to update the status of development of seismic stations and new available technology

  5. Operational Planned Core Seismic stations

  6. Core Seismic Stations, existing and planned 2010 Number Identified core stations 75 75 2007 2006 46 38

  7. WG-1 Recommendation of IOTWS • The group endorsed the high importance of sharing waveform data in real time for tsunami warning purposes. • Where the countries can not provide waveform data in real time, it is recommended to share the parametric data including phase arrival time in real time. • The SeedLink protocol and miniseed format are the recommended method for real time waveform data exchange. • The Group recommended that the seismology training should be extended to all Indian Ocean sub-Regions.

Education, BAKORNAS, LIPI, loc Gov)

  12. Institutions involved in Monitoring System • Seismograph and Accelerograph Networks • BMG, Meteorological and Geophysics Agency. • GPS and Tide Gauge networks BAKOSURTANAL, National coordinating Agency for Survey and mapping LIPI, Indonesian Science Institute • DART buoy • BPPT, Assessment and Application Technology Agency • Earth Observation • LAPAN, National Aero space Agency • Tsunami Early Warning Center • BMG, Meteorological and Geophysics Agency.

  16. BMG Improvement to reduce false WARNING • Detail information on Warning message content • Identify the affected region for every event, prior to warning message dissemination • Installation of Tsunami simulation database • Aggregate information to confirm tsunami; • OBU data related to tsunami height on the beach • Tide gauge data or tsunami height to update tsunami message • Installation of Decision Support System (DSS)

  22. Commitment for Real Time Tide gauge Stations

  23. On going development • Continue to develop new seismic stations as required for tsunami purposes • Guide to develop and evaluate seismic stations • Maintain the performance of seismic stations and networks • Require regular Training in seismology, instrumentation, Database and Metadata • Guide to support routine operation, data exchange and system communication • Introduce the seismic network and all networks for tsunami warning to universities in Indonesia (28 Universities; 2006, 2007) • Attract the attention of Student and lecturer from University • Require GUI for accessing and sharing data for research purposes (GFZ, Germany)

  24. BMG program in 2008 BMG • Complete the new building for new operation center • Move operation center from old building to new building (May 2008) • Install DSS (Decision Support System) • Install seismic processing system in BMG regional centers (10 centers) • Prepare redundant system of Warning center in Denpassar (Bali), one of BMG regional centers • Inauguration of InaTEWS, 12 November 2008
