[S-GD03] Crustal Deformation

Mon. May 26, 2025 9:00 AM - 10:30 AM Convention Hall (CH-A) (International Conference Hall, Makuhari Messe)

convener:Masayuki Kano(Graduate school of science, Tohoku University), Fumiaki Tomita(International Research Institute of Disaster Science, Tohoku University), Akemi Noda(Japan Meteorological Agency), Yuji Himematsu(Geospatial Information Authority of Japan), Chairperson:Takuya NISHIMURA(Disaster Prevention Research Institute, Kyoto University), Tomohisa Okazaki(RIKEN Center for Advanced Intelligence Project)

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.
