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
Outline • Introduction • Operation procedure for supporting global rescue activities • Data process flow for earthquake damage detection • Satellite experiments using WINDS • Conclusions
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
The IRT-JF operating in the Kingdom of Thailand (2004) • The Swiss rescue team operated at Kobe earthquake in Japan (1995 ).
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
Project goals • Low cost method for estimating earthquake damage • Appropriate solution to developing countries • Promotion of international cooperation in disaster preparedness and relief
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
WINDS: Wideband Internetworking ENgineering Test and Demonstration Satellite
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
Experiment scenario 1: Direct access for low and medium data amount Headquarter Disaster site Data network
Experiment scenario 2: Access via local data network in case of huge data amount Headquarter Disaster site Data network Data network Internet
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
