Abstract
While the seismic intensity scale shows the level of ground shaking, it is closely related to the building damage during earthquakes. The seismic intensity data are analyzed with the aim of applying to the estimation of seismic damage. The relative value of seismic intensity at an intensity observation site can be evaluated considering the local site amplification of ground motion. The local site amplification of seismic intensity is obtained from the one-dimensional multiple reflection analysis based on the soil boring data. The seismic intensity distribution of recent moderate earthquake in Tokyo metropolitan area is considered in correlation to the Ansei-Edo earthquake. It is concluded that the seismic intensity distribution of major earthquake can be evaluated using the attenuation equation and site intensity amplification data.
