[S-SS12] Statistical seismology and underlying physical processes

Wed. May 28, 2025 3:30 PM - 5:00 PM Convention Hall (CH-B) (International Conference Hall, Makuhari Messe)

convener:Keita Chiba(Association for the Development of Earthquake Prediction), Nana Yoshimitsu(Kyoto University), Chairperson:Masahiro Kosuga(Graduate School of Science and Technology, Hirosaki University), Takeshi Akuhara(Earthquake Research Institute, University of Tokyo)

This session aims to improve our understanding on seismicity. Any contribution on behavior of earthquakes as a cluster, such as regional seismicity and aftershocks, are welcomed. We also welcome contribution on temporal and spatial interactions that control seismicity, and tectonic processes, and geological and thermal structures that regulate seismicity.
