| Outline of Final Research Achievements |
To estimate fault fracture process, we developed a new analysis based on the semblance analysis that is using the seismic waveform observed in arrays. In this study, we focused on two major problems. One is to estimate rupture process in accurately by introducing multiple arrays or a new calculation methods of semblance. And another is to make possible to estimate physical value such as amount of slip or seismic moment. We applied the newly developed method to the 2011 Tohoku-Pacific Ocean Earthquake and 2007 Chuetsu-oki earthquake and confirmed our new method can be a useful tool for analyzing complex rupture process.
