COMPARISON OF THE PREDICTED GROUND MOTIONS TARGETING INTRA-PLATE EARTHQUAKE BY DIFFERENT SOURCE MODELS

Abstract

 Source modeling method for strong ground motion prediction targeting intra-plate earthquake has not been established in the technical standards for civil engineering works yet. In this study, authors applied two kinds of source model that are likely to be introduced to the practical design. One is characterized source model in accordance with the latest recipe for strong-motion prediction shown by the Headquarters for Earthquake Research Promotion and the other is pseudo point-source model proposed by Yamada et al.. Results of the study showed that pseudo point-source model gives conservative earthquake ground motions compared with the characterized source model.
