Research Interest

Megathrust earthquakes occur at subduction zones that are accompanied by strong ground motion and tsunamis. Moreover, varioius types of slow earthqukes occur on the megathrust fault. To understand such complex slip behavior of the megathrust faults, we need to know physical properties of the megathrust faults. I have tackled receiver function analysis using ocean-bottom seismometer (OBS) data. Although receiver functions calculated with OBS data suffer from water- and sediment-related reverberations, they have potential to provide a unique constraint (i.e., shear modulus) on the megathrust properties.
