| Scope |
The 2011 Mw 9.0 Tohoku-oki earthquake remains one of the best-recorded megathrust events. Fifteen years on, an exceptional variety of observations from onshore and seafloor geodesy, strong-motion and broadband seismology, tsunami and oceanographic records, geological and drilling constraints, to laboratory experiments and physics-based and data-driven modeling now enables a more integrative understanding of the full earthquake cycle.
This session invites contributions that consider pre-seismic, co-seismic, and post-seismic processes, including slip deficit and interplate coupling, foreshocks and slow earthquakes, large near-trench slip and tsunami generation, structural and material controls on rupture, aseismic afterslip, viscoelastic and poroelastic responses, stress transfer and seismicity migration, and longer-term recurrence gleaned from historical and paleo-records. We particularly welcome studies that bridge methods or disciplines such as data assimilation that fuses geodesy, seismology, and tsunami constraints; dynamic-to-kinematic rupture linkages; integration of drilling or petrological data with geophysical inversions; physics-informed neural networks (PINNs) and related machine-learning approaches grounded in physics.
Our goal is to promote cross-disciplinary synthesis that clarifies how multi-scale processes interact across the Tohoku-oki system and, by extension, other subduction zones. We encourage updates to established findings as well as new perspectives that challenge or refine prevailing views. Both observational and modeling studies are welcome, and submissions addressing implications for hazard assessment and forecasting are encouraged. Our goal is to foster integrative understanding through cross-disciplinary discussion.
