[S-SS05] Crustal Deformation

Thu. Jun 3, 2021 1:45 PM - 3:15 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:Yoshiyuki Tanaka(Earth and Planetary Science, The University of Tokyo), Keisuke Yano(The Institute of Statistical Mathematics)

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.
