1 INFORMATION NETWORK FOR EARTHQUAKE DISASTER MITIGATION IN DEVELOPING COUNTRIES Dr. Taiki SAITO Chief Researcher, IISEE Building Research Institute Tsukuba, Japan XIX INTERNATIONAL SYMPOSIUM IN HONOR OF PROFESSOR YUJI ISHIYAMA

2 INTERNATIONAL TRAINING PROGRAM ON SEISMOLOGY AND EARTHQUAKE ENGINEERING 1960 Training project started IISEE was established in BRI Joint project with UNESCO 1972 The project was continued by JAPAN Master Degree for regular course participants. Regular Course Global Seismological Observation Course Individual Course Seismology, Earthquake Engineering And Disaster Mitigation Global Seismological Observation Seismology Earthquake Engineering 12 months2 monthsArbitrary Field Period Max. Members Training Courses History

3 1,164 participants from 89 countries Unknown Others Private Company University Research Inst. Administration Seismology Course Earthquake Eng. Course

4 Background Severe earthquake damage in developing countries Weak social and economical bases Lack of technical information for earthquake disaster mitigation In order to disseminate technical information Training for seismologists and earthquake engineers Transfer of technical information Algeria Earthquake 5/21,2003, BBC News

5 Survey Results of Ex-participants Perceptions Through the IISEE Preferred way of continuous information acquisition? (Unit: person, multiple answer allowed) Technical cooperation between nations Through the Internet Journals and technical papers Attend international workshop Individual network Others Continue training program What do you expect on IISEE? (Unit: person, multiple answer allowed) International research cooperation Serve as information center Award degrees Conduct seminar New training course Others

6 IISEE-net Internet-based system designed to disseminate a variety of technical information regarding seismology and earthquake engineering. Free Web site to find technical information about seismic networks, the strong motion observatory network, seismic damage archives, seismic design codes, and microzonation data of developing countries. Technical information on IISEE-net was obtained mainly through the International Training Program on Seismology and Earthquake Engineering and its ex-participants. IISEE-net works not only as a system to disseminate technical information, but also as an forum for interactive information exchange among research institutes and researchers in developing countries.

7 IISEE-net

8 Seismic Network Seismic Activity Tectonics Example: COLOMBIA Based on country reports by the ex-participants, the Web site provides information on approximately 50 earthquake-prone countries about their seismic networks, seismic activity, tectonics, and macrozonation.

9 Seismic Damage List of Damaging EarthquakeSearch EngineSource Rupture Process (Colima, Mexico Earthquake) List of damaging earthquake and its characteristics Country report for earthquake damage Distribution of after shocks, fault mechanism, wave propagation analysis

10 Seismic Design Code Seismic Design Force Design Spectrum Zone Factor Example: MEXICO Seismic design codes of approximately 45 developing countries. A summary of the Japanese Building Standard Law European code and ISO information.

11 Microzonation Microzonation of Teheran Estimated Seismic Intensity Example: IRAN Microzonation project reports are reported from several countries focusing on their metropolitan areas. Seismic Intensity, liquefaction, building damage, etc.
