[S-SS06] Statistical seismology and underlying physical processes

Thu. Jun 3, 2021 9:00 AM - 10:30 AM Ch.20 (Zoom Room 20)

convener:Yasuhiro Yoshida(Meteorological Research Institute, Japan Meteorological Agency), Chairperson:Youichi Asano(National Research Institute for Earth Science and Disaster Prevention), Yohei Yukutake(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.
