Web-based geographical information system has been developed for understanding the damage of RC buildings in the Great Kanto Earthquake. Building damage data and analyzed results examined in the two investigation reports about the 1923 Great Kanto Earthquake in the City of Tokyo are included in the system. This system integrates various kinds of data such as damage data examined in old reports, estimated seismic intensity, newly observed micro-tremor data, old maps and digital elevation topographical map. This is useful for engineers to assist estimating the structural performance of historical modern architecture, and for citizen to consider the importance of disaster mitigation countermeasure.
