[S-CG66] [EE] Shallow and intermediate depth intraslab earthquakes: seismogenesis and rheology of the slab
Tue. May 23, 2017 3:30 PM - 5:00 PM Poster Hall (International Exhibition Hall HALL7)
convener:Tomohiro Ohuchi(Geodynamics Research Center, Ehime University), Saeko Kita(Department of Earth and Planetary Systems Science, Hiroshima University), Brent G Delbridge(Berkeley Seismological Lab), Ikuo Katayama(Department of Earth and Planetary Systems Science, Hiroshima University)
The rheological behavior of subducting slabs contributes to the generation and occurrence of intraslab earthquakes; however, we currently lack an understanding of the physical mechanisms linking these properties to the generation of intraslab earthquakes. The purpose of this session is to share constraints and advances in the understanding of the mechanisms that generate shallow and intermediate depth earthquakes, including both brittle and ductile flow rheologies. We seek to formulate future directions of the interdisciplinary study of the occurrence of intraslab earthquakes from the viewpoint of seismology, geodynamics and mineral physics. We welcome presentations from a wide variety of scientific disciplines, including observational and theoretical seismology, seismotectonics, geodynamics, mineral and rock physics, geology, and numerical modeling. Studies related to the thermal and tectonic structures of the subducting slab are also welcomed.
