Abstract
A Web-GIS based system is developed for utilization of seismic records observed by a number of organizations and its effective integration by data interoperation technology on the Internet. Various data on ground, building and regional conditions are collected and viewed on the Web GIS, such as geological condition on shallow and deep soil, structural specification on the observed buildings, estimated distribution of seismic intensity and seismic waves, and indices on disaster mitigation potential of the area. Further aspects on utilization of the system for aseismic structural design, regional disaster mitigation and disaster education are also discussed. New ways for low-cost and efficient seismic observation procedure are introduced using the developed system with assistance of school teachers and students, engineers, building users and the persons who are interested in the seismic observation and disaster mitigation.
