In the last decade, there have been tremendous advancements in methodologies to extract records of past earthquake shaking from onshore and offshore sediment archives (e.g. giant piston coring in hadal trenches and lacustrine ground motion modelling). Integration of these methods has thus far been limited, but tracking earthquake-shaking across land-to-sea transects has potential to elevate fundamental understanding of rupture processes, earthquake recurrence and associated hazards. Hence, we aim to gather international experts ranging from marine seismologists to limnologists, and students to senior scientists, to coordinate impactful future scientific endeavours and drilling proposals aimed at collectively advancing scientific understanding of seismic hazard at active plate boundaries.
