		| Scope | The goal of this session is comprehensive understanding of geodynamics of island arcs in subduction margins, including their structural evolution, short- and long-term crustal deformation, seismicity, crustal and mantle architectures overprinted by structural histories, volcanisms, and rheological properties of the lithosphere and its response to geodynamic processes.  We solicit contributions from a wide range of disciplines, including geodynamics, tectonics, geophysics, geochemistry, seismology and earthquake prediction, from both observational, numerical and experimental approaches. |
