  abstract = {{T}he {N}azca {R}idge subduction beneath the {P}eruvian forearc presents a unique setting to evaluate the interplay between buoyant ridge subduction and continental forearc deformation. {T}he current understanding of forearc deformation is largely based on numerical models with limited, field-based input data from small areas. {T}his paper therefore presents a reconstruction of tectonic deformation in this region based on two topographic profiles across the entire continental forearc. {T}he forearc overlying the ridge crest and leading edge hosts the large {Q}uaternary {N}azca {P}eneplain ({QNP}), which has registered uplift and deformation since the onset of ridge subduction. {W}e developed a {C}onditional {V}ariational {A}utoencoder ({CVAE}) deep learning model to reconstruct the {QNP} to its pre-eroded state and used this surface as input for two retrodeformed topographic profiles. {T}he {QNP} and adjacent marine terraces were then dated using cosmogenic nuclide exposure and luminescence methods and used to calculate deformation rates. {F}orearc deformation involves uplift primarily due to folding, with basal thrusting or buoyancy of the {N}azca {R}idge acting as secondary drivers. {S}hortening rates since 1.85 +/- 0.18 {M}a to the present range from 0.32 to 0.36 mm a-1, and surface uplift rates up to 0.37 mm a-1. {T}he 1.85 +/- 0.18 {M}a age combined with a regional bounding surface between shallow marine and fluvial gravels, provides an estimate for the timing of {N}azca {R}idge-overriding plate coupling. {T}hese results align with, and refine, previous numerical predictions on forearc deformation due to buoyant ridge subduction and offer a high-resolution dataset for future studies.},
