[S-SS11] Strong Ground Motion and Earthquake Disaster

Fri. May 30, 2025 1:45 PM - 3:15 PM Convention Hall (CH-B) (International Conference Hall, Makuhari Messe)

convener:Hisahiko Kubo(National Research Institute for Earth Science and Disaster Resilience), Yusuke Tomozawa( KAJIMA Corporation), Chairperson:Kensuke Arai(Shimizu Corporation), Yusuke Tomozawa(KAJIMA Corporation)

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.
