スコープ和文
英文The purpose of this session is to share recent advances of geo-scientifical studies for intraslab (intraplate) earthquakes. We seek to formulate future directions of the interdisciplinary study of the occurrence of intermediate-depth intraslab earthquakes from the viewpoint of seismology, geodynamics and mineral physics. We welcome presentations from a wide variety of scientific disciplines, including seismology, seismotectonics, geodynamics, mineral and rock physics, other geophysics, geology, and numerical modeling. Studies for outer-rise earthquakes, shallow-depth intraplate earthquakes and deep earthquakes are also welcomed because it is important to know the characteristics of shallow-depth intraslab earthquakes and deep earthquakes for understanding for the generation process of intermediate-depth intraslab earthquakes.
