Seismotectonics in subduction zones
I have been working to understand seismo- and volcano-tectonics in subduction zones. My research includes seismic velocity and attenuation tomography, spectral analyses of waveforms, plate geometry, and related topics.
* Seismic tomography (velocity and attenuation)
* Seismic imaging of arc magmatism
* Genesis of intraslab earthquakes ~ fluid-related embrittlement~
* Genesis of crustal earthquakes
* Heterogeneous structure around tremor and LFEs
* Fluid migration above the megathrust
* Plate geometry of the Pacific and Philippine Sea plates around Japan
* Dehydration in the slab crust
* Seismicity (LFEs, repeating earthquakes, and earthquake swarm)
