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