  abstract = {{I}n the context of increasing evidence of plate interface coupling variability in subduction zones, there is a need to extend the short time window given by instrumental data and to gather data over multiple time and spatial scales. {W}e hence investigated the long-term topography on {B}arbuda island, located in the northern part of the {L}esser {A}ntilles, west of the {C}aribbean subduction zone. {F}ollowing pioneering work using a set of marine terraces on the eastern side of the island, we performed the first {U}-{T}h dating on 10 corals in growth position from the lowest terrace, for which the highest relative sea-level ({RSL}) indicator is found at 9 +/- 1 m above the mean sea level. {W}e find that this terrace corresponds to the {L}ast {I}nterglacial ({LIG}) (ages between 122.8 +/- 0.3 ka and 128.1 +/- 0.3 ka) and we estimate a paleo {RSL} of 7 +/- 2 m above the current mean sea level. {T}he present elevation of the {LIG} shoreline on {B}arbuda might imply tectonics as an additional mechanism to eustatic sea level, mantle dynamic topography and glacial isostatic adjustment. {E}ast-west morphological asymmetry of {B}arbuda and difference in {LIG} shoreline elevation between {B}arbuda and {A}ntigua suggest a regional tectonic process. {A}s with the proposed westward tilting from the forearc to the volcanic arc of the {G}uadeloupe archipelago, vertical deformation on {B}arbuda could be related to plate-scale subduction processes. {L}ong-term uplift of {B}arbuda might be related to the accumulation of residual coseismic deformation not fully recovered by interseismic subsidence and the corresponding seismogenic segment would extend below the {M}oho.},
