[S-SS05] Crustal Deformation

Thu. Jun 3, 2021 3:30 PM - 5:00 PM Ch.22 (Zoom Room 22)

convener:Masayuki Kano(Graduate school of science, Tohoku University), Tadafumi Ochi(Institute of Earthquake and Volcano Geology, Geological Survey of Japan, The National Institute of Advanced Industrial Science and Technology), Fumiaki Tomita(Japan Agency for Marine-Earth Science and Technology), Chairperson:Yusaku Ohta(Research Center for Prediction of Earthquakes and Volcanic Eruptions, Graduate School of Science, Tohoku University), Yusuke Yokota(Institute of Industrial Science, The University of Tokyo)

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.
