Our main research interest is the thermal structure of subduction zones, which can be estimated through measurements of terrestrial heat flow and numerical models taking account of other geophysical and geological information. We have been studying thermal structures of Nankai Trough and Japan Trench subduction zones and revealed that the heat flow distributions around the trenches are closely related to the structure of the oceanic crust and pore fluid flow in the crust. For investigation of the causes of the relationships and their influence on physical processes in the seismogenic zone, we are conducting more detailed measurements and modeling of fluid flow and heat transport. We also study seafloor fluid discharge, groundwater flow and the past ground surface temperature history through high-precision and long-term temperature measurements in marine sediments and land boreholes.
