[S-SS09] Strong Ground Motion and Earthquake Disaster

Mon. May 22, 2023 9:00 AM - 10:30 AM 301A (International Conference Hall, Makuhari Messe)

convener:Takumi Hayashida(International Institute of Seismology and Earthquake Engineering, Building Research Institute), Yasuhiro Matsumoto(Kozo Keikaku Engineering), Chairperson:Nobuyuki Morikawa(National Research Institute for Earth Science and Disaster Resilience), Fumiaki Nagashima(Disaster Prevention Research Institute, Kyoto University)

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.
