Research Abstract

In this study, I show results of the prediction of future Tonankai and Nankai earthquakes. Our target period is form 1.0 to 20.0s ground motions that affect the damage of high-rise buildings. Next I performed 3D ground motion simulation of the 2007 Niigataken Chuetsu-oki earthquake and 3D ground motion simulation of Osaka basin using virtual source model to estimate the influence of 3D underground structure.
