[S-SS09] Strong Ground Motion and Earthquake Disaster

Sun. May 21, 2023 10:45 AM - 12:00 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

convener:Takumi Hayashida(International Institute of Seismology and Earthquake Engineering, Building Research Institute), Yasuhiro Matsumoto(Kozo Keikaku Engineering), Chairperson:Yasumaro Kakehi(Department of Planetology, Graduate School of Science, Kobe University), Ikuo Cho(National Institute of Advanced Industrial Science and Technology)

This session discusses strong ground motion directly related to earthquake disasters. We call for presentations aimed at understanding phenomena based on theory and observations, such as source characteristics, seismic wave propagation, and site amplification factors that characterize ground shaking. We also welcome research presentations and proposals for mitigating future earthquake disasters.
