[S-SS26] Seismic wave propagation: Theory and Application

Tue. May 26, 2015 4:15 PM - 5:45 PM 103 (1F)

Convener:*Tatsuhiko Saito(National Research Institute for Earth Science and Disaster Prevention), Hisashi Nakahara(Solid Earth Physics Laboratory, Department of Geophysics, Graduate School of Science, Tohoku University), Jun Matsushima(School of Engineering, The University of Tokyo), Kiwamu Nishida(Earthquake Research Institute, University of Tokyo), Kazuya Shiraishi(JGI, Inc.), Chair:Takuto Maeda(Earthquake Research Institute, the University of Tokyo), Kaoru Sawazaki(National Research Institute for Earth Science and Disaster Prevention)

In order to deeply understand seismic wave propagation through the heterogeneous earth and to successfully extract the properties of the heterogeneity from the observed seismograms, integrated studies are needed among mathematical/numerical studies based on the wave theory, miniature physical experiments using rock specimens, and practical data analyses. Furthermore, it is greatly beneficial to conduct comparative studies of various kinds of waves such as elastic, acoustic, electromagnetic, and oceanic waves. This session widely invites presentations about theories and applications related to seismic and other geophysical waves.
