| スコープ | 和文 | The purpose of this session is to share recent advances of geo-scientifical studies for intraslab and shallow-depth intraplate earthquakes. We seek to formulate future directions of the interdisciplinary study of the occurrence of intermediate-depth and deep 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. | |
