[M-IS33] Progress in marine geoscience off Pacific coast of Tohoku after the 2011 earthquake and tsunami

Tue. May 26, 2015 2:15 PM - 3:00 PM 102B (1F)

Convener:*Kazuko Usami(Institute of Geology and Geoinformation, National Institute of Advanced Industrial Science and Technology), Ken Ikehara(Institute of Geology and Geoinformation, National Institute of Advanced Industrial Science and Technology), Yoshihiro Ito(Disaster Prevention Research Institute, Kyoto University), Takashi Toyofuku(Japan Agency for Marine-Earth Science and Technology (JAMSTEC)), Chair:Kazuko Usami(Institute of Geology and Geoinformation,)

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.
