| Outline of Final Research Achievements |
In SW Japan and Cascadia we observe that the amount of slip by short-term slow slip events (which is a type of slow earthquakes) is large where the slab bends away from the trench. In this study we demonstrated that these observations may reflect 3D fluid migration due to complex slab geometries by using numerical models including the effects of permeability anisotropy in the serpentine layer on top of the slab.
