| Outline of Final Research Achievements |
Crustal deformation observed by geodetic survey is the sum of elastic strain and permanent strain. The schedule at the start of the study was to focus on crustal movements around active faults. However, the 2014 Kamiro fault earthquake occurred. In the earthquake, a surface rupture appeared, but it was a smaller than a characteristic earthquake. This proved that there are multiple cases of earthquakes occurring along the active fault. It was also found that the crustal deformation observed by geodetic survey changes under the influence of the surrounding crustal movement event. The results of this research show that the crustal deformation in the island arc due to the slip of active fault is part of the whole deformation system and showed the necessity to consider the comprehensive crustal deformation process in the next step.
