[S-SS10] Strong Ground Motion and Earthquake Disaster

Tue. May 28, 2024 9:00 AM - 10:30 AM 302 (International Conference Hall, Makuhari Messe)

convener:Yusuke Tomozawa( KAJIMA Corporation), Takumi Hayashida(International Institute of Seismology and Earthquake Engineering, Building Research Institute), Chairperson:Kazuki Koketsu(SFC Research Institute, Keio University), Kosuke Chimoto(Kagawa 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.
