Knowledge on subduction zone earthquake phenomena has considerably increased in the last decade. On the other hand, there are limits to seismological approach alone to comprehensively elucidate the earthquake mechanism in which phenomena that differ drastically in space and time, from earthquake nucleation/growth processes to its driving force. Steps to enable scientific earthquake forecasting should include; monitoring regional seismic/tectonic activity using networked observatories, sampling of and insitu measurement in seismogenic faults and plate materials through ultra-deep drilling, and reproduction/insitu-observation of fracture nucleation processes by high-pressure quantum-beam experiments. Through a close collaboration, we challenge a dynamic imaging of earthquake processes. This year, we focus on the state & property of seamount subduction and its possible consequence on seismicity. We welcome, but not limited to, presentations from fields of ocean and land networks observation, seismogenic zone drilling, rock mechanical & quantum beam experiments, fracture process theory, etc.
