[S-SS24_1PM2] Seismicity

Thu. May 1, 2014 4:15 PM - 6:00 PM 315 (3F)

Convener:*Yoshihiro Ito(Disaster Prevention Research Institute, Kyoto University), Chair:Tomoko Elizabeth Yano(National Research Institute of Earth Science and Disaster Prevention), Ryoya Ikuta(Faculty of Science, Shizuoka University)

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