[S-CG64_30PM2] Slow earthquakes

Wed. Apr 30, 2014 4:15 PM - 6:00 PM 501 (5F)

Convener:*Hitoshi Hirose(Research Center for Urban Safety and Security, Kobe University), Kazushige Obara(Earthquake Research Institute, The University of Tokyo), Ryoko Nakata(Japan Agency for Marine-Earth Science and Technology), Chair:Ryoko Nakata(Japan Agency for Marine-Earth Science and Technology), Naoki Suda(Department of Earth and Planetary Systems Science, Graduate School of Science, Hiroshima University)

A variety of slow earthquakes, such as slow slip events, low frequency tremor, very low frequency earthquakes, and so on, has been observed in various geological environments, e.g., subduction plate boundaries and volcanoes. This session welcomes contributions on any aspect of the phenomena including observational, theoretical, and experimental studies from various fields for understanding the nature of these phenomena through interdisciplinary and comprehensive discussions.
