Abstract: Large earthquakes are a potentially important source of relative sea level variations, since they can drive global deformation and simultaneously perturb the gravity field of the Earth. For the first time, we formalize a gravitationally self–consistent, integral sea level equation suitable for earthquakes, in which we account both for direct effects by the seismic dislocation and for the feedback from water loading associated with sea level changes. Our approach builds upon the well established theory first proposed in the realm of glacio–isostatic adjustment modeling. The seismic sea level equation is numerically implemented to model sea level signals following the 2004 Sumatra–Andaman earth- quake, showing that surface loading from ocean water redistribution (so far ignored in post–seismic deformation modeling) may account for a significant fraction of the total computed post–seismic sea level variation.
