3 3 Activities of BRI / IISEE IISEE Training Course (for participants from developing countries) IISEE net (Web site for information transfer)

4 4 History 1960 IISEE Training Course Seismology Course and Earthquake Engineering Course The necessity of the training on seismology and earthquake engineering was emphasized at the 2nd WCEE (World Conference on Earthquake Engineering) in Tokyo and 1961 The training course was held at University of Tokyo and Waseda University IISEE was established at BRI as the training organization supported by JICA. Special Lecture by Dr. Carlos Zavala, Peru

5 5 History 2004 IISEE Training Course Tsunami Disaster Mitigation Course Gigantic tsunami generated by a major earthquake off Sumatra wreaked havoc on the coastal areas of the Indian Ocean In response, the Tsunami Disaster Mitigation Course was established. Tsunami Simulation at Sumatra in 2004 Study Trip

11 11 IISEE net Web site Country List

12 12 IISEE net Seismic Network 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. Example: COLOMBIA Seismic Network Seismic Activity Tectonics

13 13 IISEE net Seismic Damage List of damaging earthquake and its characteristics Country report for earthquake damage Distribution of after shocks, fault mechanism, wave propagation analysis List of Damaging Earthquake Search Engine Source Rupture Process (Colima, Mexico Earthquake)

14 14 IISEE net Seismic Design Code Seismic design codes of approximately 45 developing countries. A summary of the Japanese Building Standard Law European code and ISO information. Example: MEXICO Seismic Design Force Design Spectrum Zone Factor

15 15 IISEE net Microzonation Microzonation project reports are reported from several countries focusing on their metropolitan areas. Seismic Intensity, liquefaction, building damage, etc. Example: IRAN Microzonation of Teheran Estimated Seismic Intensity
