Research Interests:　

One of the most important aspects of plate subduction zones is that they represent the sites of the world's
     largest earthquakes; moreover, they are fundamental components of mountain belts.In addition,submarine
     landslides in such regions heighten the risk for tsunamis, which can affect coastal communities and offshore
     infrastructure. To understand the geological and seismological significances,it is important to study primary
     subduction processes and progressive variation of deformation styles and related changes in physical
     properties of sediments along the plate interface. We are studying the nature of deformations by means of
     outcrop- and ocean drilling (IODP)-based studies, and construct geologic hypotheses. Then, we are going to
     demonstrate them by our experimental studies. We are working with many of international collaborators.
     We will welcome you to our lab.

Recent research topics:　

  • Various geologic phenomena (e.g., earthquake, submarine landslide, etc.) in plate convergent margins
  • Deformation and related phys. props variation of sediments between trench to seismogenic zone
  • Any secrets of the Earth
  • Tectonics: especially, Island-arc collision
  • Geo-thermometry for short geologic events using organic matters
