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.
