IISEE-net　 http: //iisee. kenken. go. jp/net/index. htm | 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.

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 Tectonics Seismic Network Seismic Activity

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)

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

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
