[S-SS11] Statistical seismology and underlying physical processes

Wed. May 25, 2022 9:00 AM - 10:30 AM 103 (International Conference Hall, Makuhari Messe)

convener:Kazuyoshi Nanjo(University of Shizuoka), convener:Makoto Naoi(Kyoto University), Chairperson:Kazuyoshi Nanjo(University of Shizuoka), Takao Kumazawa(Earthquake Research Institute, The 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.
