[S-SS33_30AM1] Crustal Deformation

Wed. Apr 30, 2014 9:00 AM - 10:45 AM 315 (3F)

Convener:*Masayuki Murase(Department of Geosystem, College of Humanities and Sciences, NIHON University), Yusaku Ohta(Research Center for Prediction of Earthquakes and Volcanic Eruptions, Graduate School of Science, Tohoku University), Chair:Masayuki Murase(Department of Geosystem, College of Humanities and Sciences, NIHON 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.
