Outline of Final Research Achievements

The aim of this research is to mitigate a seismic disaster through the support for the decision making of house owners on upgrading of their houses and for the formulation of efficient measures by a local government. A methodology of accurately estimating the ground motion intensity at the location of each house using the information of soil conditions through boring data and using the ground motion intensities estimated at the boring sites is developed on the basis of geostatistics. In order to utilize the above detailed information of ground motion intensity, damage functions for a house with a given strength and under a ground motion measured by peak ground velocity are developed considering the differences in the soil conditions and the magnitude of an earthquake. The validity of the damage functions is investigate on the basis of the results of field survey, and then a system for estimating seismic risk for each house is developed.
