Research Abstract

In the present study, we propose to use a new method for the prediction of strong groud motion induced by earthquakes. Although the method has a potential to predict accurate ground motion in a simple manner, the method has not been applied to the estimation of ground motion yet. Therefore, we investigated the applicability of this method to the estimation of strong ground motion. Our results revealed that this method can predict ground motion more accurate that the conventional methods in a simple manner.
