Name Kazutoshi Imanishi Affiliation National Institute of Advanced Industrial Science and Technology Co-convener 2. Name Makoto Otsubo Affiliation National Institute of Advanced Industrial Science and Technology (AIST), Institute of Geology and Geoinformation Co-convener 3. Name Aitaro Kato Affiliation Earthquake Research Institute, University of Tokyo International Symposium No request Language Japanese Scope Deformation and stress fields and their temporal changes are keys to understanding the Earth's crustal dynamics. Methods for estimating crustral stress state have been developed in each discipline such as seismology, structural geology and geotechnology. For example, the following methods are widely employed; stress tensor inversion techniques to analyze focal mechanisms of earthquakes, orientations of faults, dikes, veins and microcracks gathered from outcrops and hand specimens, in situ stress measurements in boreholes and paleopiezometers such as calcite twins and micro boudinages. For the purpose of discussing crustal dynamics, this session aims at sharing achievements and unsolved problems in studies of crustal stress and deformation interdisciplinarily. We welcome presentations of methodology, application, rock experiments, and numerical simulations. Type of presentation Oral and Poster presentation Invited papers NISHIKAWA, Osamu （Akita University）
