Adapting the Africa Array Model – Building Capacity Around the WorldBoston,18-19 February 2008
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
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
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

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.

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)

• Warning is issued based on estimated tsunami height at identified beaches– H > 3 m; Major tsunami– 0.5m <H <3m ; Tsunami– H < 0.5m ; Advisory
• Update the warning based on the observation– Earthquake parameter– Tide gauges network– Buoys networks– GPS network– Image satellite

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)
BMG program in 2008• 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
