Outline of Final Research Achievements

In this study, we found that the definition of source-to-site distance, a fundamental variable in the ground motion prediction equation, can be improved. We then proposed a new source-to-site distance called the median line distance (MED). Based on this distance and the strong motion database including those from recent Japanese earthquakes, we developed a new ground motion prediction equation on the bedrocks. In the new equation, apparent source effects, such as the hanging wall effect, can be solved to some extent. The knowledge obtained in this study is expected to contribute to an advancement of probabilistic ground motion assessment.
