Convener	Yoshihiro Ito
Scope	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.
