Fri. Jun 3, 2022 11:00 AM - 1:00 PM Online Poster Zoom Room (19) (Ch.19)

convener:Tadafumi Ochi(Institute of Earthquake and Volcano Geology, Geological Survey of Japan, The National Institute of Advanced Industrial Science and Technology), convener:Masayuki Kano(Graduate school of science, Tohoku University), Fumiaki Tomita(International Research Institute of Disaster Science, Tohoku University), convener:Yusuke Yokota(Institute of Industrial Science, The University of Tokyo), Chairperson:Tadafumi Ochi(Institute of Earthquake and Volcano Geology, Geological Survey of Japan, The National Institute of Advanced Industrial Science and Technology), Masayuki Kano(Graduate school of science, Tohoku University)

Study of crustal deformation plays an extremely important role in the investigation of wide scale earth dynamics those are earthquake and volcanic activity, plate motion and so on. In our session, we discuss the study related to crustal deformation, such as development of observation instrument, observed crustal deformation, analysis method, and simulation study.
