[S-SS09] Seismic wave propagation: Theory and Application

Sat. Jun 5, 2021 9:00 AM - 10:30 AM Ch.18 (Zoom Room 18)

convener:Kaoru Sawazaki(National Research Institute for Earth Science and Disaster Resilience), Kiwamu Nishida(Earthquake Research Institute, University of Tokyo), Takao Nibe(JAPEX), Kyosuke Okamoto(National Institute of Advanced Industrial Science and Technology), Chairperson:Kaoru Sawazaki(National Research Institute for Earth Science and Disaster Resilience), Kurama Okubo(National Research Institute for Earth Science and Disaster Resilience)

Seismic wave propagation provides rich information on earth's heterogeneities and the excitation sources. Understanding of this information requires various research fields:
mathematical/numerical studies based on wave theory, physical experiments using rock samples, seismic data analysis, etc. With recent developments of observational techniques, various wave phenomena have been elucidated: seismic waves, acoustic waves, traveling ionospheric disturbances, and tsunamis. New frameworks will be crucial for comprehensive understanding of these phenomena. This session widely invites presentations about the theories and applications related to seismic and other geophysical waves.
