[S-SS11] Strong Ground Motion and Earthquake Disaster

Sat. Jun 5, 2021 3:30 PM - 5:00 PM Ch.18 (Zoom Room 18)

convener:Kazuhiro Somei(Geo-Research Institute), Yasuhiro Matsumoto(Kozo Keikaku Engineering), Chairperson:Tomohisa Okazaki(RIKEN Center for Advanced Intelligence Project), Kentaro Emoto(Graduate School of Science, Tohokuk University)

Strong ground motion has social impacts as it induces earthquake disasters. We solicit contribution on any seismological topics related to strong ground motion that includes, but are not limited to, source processes, wave propagation, and site effects. We also welcome contribution on earthquake related disaster mitigation.
