Outline of Final Research Achievements

We revealed that heat flow significantly varies at a scale of 3 to 5 km on the incoming Pacific plate seaward of the Japan Trench. The short-wavelength heat flow variation can be attributed to heterogeneity in development of fractures and fluid circulation in oceanic crust due to bending of the plate near the trench. We also estimated the electrical resistivity structure seaward of the Japan Trench using electromagnetic survey data and could obtain information on water distribution in the upper part of the Pacific plate and its variation toward the trench.
