Sea level change doesn't just flood cities, it can also move the ground under them. up and down. Rapid sea-level rise drives increased faulting, and when we look at it relative to glacial sea-level change, one can also see it.

Post-LGM intensification of marine faulting: resolution-dependent hazard assessment

Abstract. In marine environments, site-specific fault hazard assessments conventionally calculate average slip rates by measuring the displacement of the youngest mappable stratigraphic horizon. However, due to data resolution limits, this horizon is typically tens to hundreds of thousands of years old. Consequently, hazard surveys provide long-term averages that may mask recent, non-linear fault behavior. In this study, we examine how increasing stratigraphic resolution affects the calculated s

How is this for a feedback loop? Ice sheets build up during a glaciation lowering global sea level → reduced water load leads to increased mid ocean ridge volcanism after a 10-20 kyr lag → volcanism releases iron in the ocean → iron causes plankton blooms → atmospheric CO₂ goes down → ice sheets build up #ClimateChange #IceSheets #SeaLevel https://www.nature.com/articles/s41561-026-01982-7
