The mission of the division of Geosphere and Geotechnical Engineering is to conduct education and research that contribute to the survey, design, construction, and maintenance of infrastructures related to the geosphere and ground, prevention, and mitigation of geohazards, and creation and utilization of the geosphere environment. This division explores the mechanisms of earth activities and unravels the linkage between earth activities and geotechnical engineering issues. We also aim to elucidate the mechanisms of geo-disasters and to develop effective disaster prevention and mitigation measures. Furthermore, we actively utilize innovative digital technologies and data-driven approaches to promote research based on soil mechanics and geotechnical engineering.
