  1. Distribution of Earthquake Damage Estimation using Broadband Satellite Communications for Supporting International Rescue Operations Hoang Nam Nguyen Disaster Management and Mitigation Group National Institute of Information and Communications Technology

  2. Outline • Introduction • Operation procedure for supporting global rescue activities • Data process flow for earthquake damage detection • Satellite experiments using WINDS • Conclusions

  3. Introduction • Motivations and Aims of the project • Provide an appropriate solution of earthquake risk evaluation to developing countries • Support International Rescue Team of Japanese Fire-Service (IRT-JF) when operating in earthquake-stricken countries • Project activities • Earthquake damage estimation • Satellite communications experiments • International cooperation • Earthquake preparedness • Data distribution • Satellite communications experiments

  4. The IRT-JF operating in the Kingdom of Thailand (2004) • The Swiss rescue team operated at Kobe earthquake in Japan (1995 ).

  5. Operation procedure to support International Rescue Team of Japanese Fire-Service (IRT-JF) • Preparedness period • Evaluating the risk by earth quake using DEM Earth Observation Satellite (Terra-ASTER) Earth Observation Satellite (ALOS-PAL-SAR) Communications Satellite (WINDS, ETS-VIII) 2. Information gathering period • Detect collapsed building 4. Rescue period - Information exchange between headquarter and disaster site 3. Dispatching JRT-JF team Disaster site Headquarter

  6. Project goals • Low cost method for estimating earthquake damage • Appropriate solution to developing countries • Promotion of international cooperation in disaster preparedness and relief

  7. Data process flow Terra/ASTER preparation period 1995 Kobe Earthquake ALOS/PALSAR DEM Landform SAR images Elevation Amplification (R) Fault A earthquake occur Information gathering period Epicenter location, magnitude etc. SAR image ～110kine 63～ 110kine 35～ 63kine Dispatch period Shake map: (Vmax) Coherence or difference image Inside of the line shows intensity of 7 in Japanese scale based on ground survey (Vmax) & (Coherence ratio or difference) & (landcover) Damage detection map Rescue period Via WINDS Dispatched team in stricken country

  8. WINDS: Wideband Internetworking ENgineering Test and Demonstration Satellite

  9. SDR-VSAT: Super high Data Rate VSAT HDR-VSAT: High Data Rate VSAT USAT: Ultra Small Aperture Terminal MBA: Multi-Beam Antennas APAA: Active Phased Array Antennas

  10. Experiment scenario 1: Direct access for low and medium data amount Headquarter Disaster site Data network

  11. Experiment scenario 2: Access via local data network in case of huge data amount Headquarter Disaster site Data network Data network Internet

  12. Conclusion • This project aims to develop a low cost method for earthquake damage estimation which is suitable for developing countries • WINDS is used for testing and verifying utilizations of broadband satellite communications in supporting rescue activities of IRT-JF teams • Cooperation with NECTEC in WINDS’s experiments • We expect to bring collaboration opportunities to Asian countries in emergency preparedness and disaster mitigation in case of future earthquakes
