The largest earthquakes globally occur along plate boundaries, producing intense shaking and associated secondary hazards over broad regions. In the past few years, there have been significant improvements in the quantity and quality of geodetic, seismological, and geological observations of the slow accumulation and rapid release of strain at these plate boundaries. At the same time, improvements in modeling techniques are providing new insights into the geodynamic processes controlling the occurrence of major earthquakes. With these advances, it is now becoming possible to address outstanding issues about both seismic and aseismic deformation at plate boundaries, such as time-variable locking and unlocking of the plate interface, the extent and role of slow slip events, the links between earthquake cycles and permanent deformation, and the behavior of complete cycles revealed by paleo-seismic and paleo-geodetic observations.

We invite contributions that investigate the spectrum of deformation occurring throughout the earthquake cycle at plate boundaries, from aseismic to seismic and across a variety of spatial and temporal scales. Submissions that utilize improved remote and field observational capabilities, developments in data analysis, or innovations in analog and numerical modeling to advance the understanding of the underlying physical processes are encouraged.
