Outline of Final Research Achievements

For a better estimation of earthquake hazard and disaster, this research studies the three targets, taking advantage of Integrated Earthquake Simulation (IES).
The first target is the development of next-generation urban model. A new module of automated model construction which is applicable to civil infrastructures such as bridge networks is developed; an existing module is for residential buildings. The second target is the development of an analysis methodology for IES results. A methodology that is based on the fundamental mechanism of seismic response of ground and structure, the amplification of response components of natural frequencies, is established. The third target is the execution of multi-earthquake scenario IES. It is shown that earthquake hazard and disaster in Tokyo Metropolis are computed by using IES, and the results are analyzed, which indicates the applicability of the multi-earthquake scenario IES to actual cities.
