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

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

5. 5 Operation procedure to support International Rescue Team of Japanese Fire-Service (IRT-JF) Earth Observation Satellite (Terra-ASTER) Earth Observation Satellite (ALOS-PAL-SAR) Communications Satellite (WINDS, ETS-VIII) Disaster site Headquarter 1.Preparedness period Evaluating the risk by earth quake using DEM 2. Information gathering period Detect collapsed building 3. Dispatching JRT-JF team 4. Rescue period - Information exchange between headquarter and disaster site

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