[S-GD02] Crustal Deformation

Tue. May 23, 2023 9:00 AM - 10:15 AM 304 (International Conference Hall, Makuhari Messe)

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(International Research Institute of Disaster Science, Tohoku University), Chairperson:Mako Ohzono(Institute of Seismology and Volcanology, Faculty of Science, Hokkaido University), Tadashi Yamasaki(National Institute of Advanced Industrial Science and Technology)

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.
