| Outline of Final Research Achievements |
The advancement of earthquake ground motion and crustal deformation observation is being promoted in order to mitigate earthquakes and to elucidate the mechanisms of earthquake phenomena. In order to make better use of such advanced observation data, more detailed analysis has been required, but this has been difficult to achieve because the analysis cost is too large. In this research project, we have created a new analysis method by utilizing state-of-the-art computational science and computer science, and demonstrated the effectiveness of the developed method by applying it to actual problems based on state-of-the-art measurements and the latest knowledge from solid earth science.
