Name Takashi Toyofuku Affiliation Japan Agency for Marine-Earth Science and Technology (JAMSTEC) Email toyofuku@jamstec.go.jp International Symposium No request Language Japanese Scope Many studies on submarine topography and structure, tectonic deformation, sediment and radioactive material movement and marine biology at off Pacific coast of Tohoku region have been proceeded after the 2011 off the Pacific coast of Tohoku Earthquake and tsunami. In this session, we discuss drastically expanded knowledge and results by these studies carried out at the Japan Trench, inner slope and shallow-water regions along with the changes of marine environments, sea-floor sediments and sea bottom through four years after the earthquake, leading interdisciplinary knowledge sharing. We will organize "what occurred corresponding to the earthquake and tsunami" and "what is going on in the area after the 2011 event", indicating future direction of the survey, through the oral/poster papers and discussion. Type of presentation Oral and Poster presentation Invited papers Ryota Hino (Tohoku University) Hiroshi Kitazato (JAMSTEC)
