[S-SS31] Crustal Deformation

Mon. May 25, 2015 2:15 PM - 4:00 PM 304 (3F)

Convener:*Yusaku Ohta(Research Center for Prediction of Earthquakes and Volcanic Eruptions, Graduate School of Science, Tohoku University), Masayuki Murase(Department of Geosystem, College of Humanities and Sciences, NIHON University), Chair:Mako Ohzono(Faculty of Science, Yamagata University), Kosuke Heki(Department of Natural History Sciences, Faculty of Science, Hokkaido 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.
