  abstract = {{W}e present the results of a paleoseismic survey of the {I}ncapuquio {F}ault {S}ystem, a prominent transpressional fault system cutting the forearc of {S}outh {P}eru. {H}igh-resolution {D}igital {E}levation {M}odels, optical satellite imagery, radiocarbon dating, and paleoseismic trenching indicate that at least 2-3 m of net slip occurred on the {I}ncapuquio {F}ault generating a complex, similar to 100-km long set of segmented fault scarps in the early 15th century (similar to 1400-1440 {CE}). {W}e interpret the consistent along-strike pattern of fault scarp heights, geometries and kinematics to reflect a surface rupture generated by a single {M}-w 7.4-7.7 earthquake, suggesting that brittle failure of the forearc poses a significant, yet mostly overlooked, seismic hazard to the communities in coastal areas of {P}eru. {T}he timing of this earthquake coincides with the collapse of the {C}hiribaya civilization in similar to 1360-1400 {CE}, and we present evidence of damaged buildings along the fault trace that may be of {C}hiribayas age. {O}ur surface faulting observations, when combined with observations of deformation in the forearc from geodesy and seismology, also demonstrate that the forearc in {S}outh {P}eru experiences a complex, time-varying pattern of permanent strain, with evidence for trench-parallel shortening, trench-parallel extension, and trench-perpendicular shortening all in close proximity but in different periods of the megathrust earthquake cycle. {T}he kinematics of recent slip on the {I}ncapuquio {F}ault are consistent with the sense of interseismic strain within the forearc measured by {GPS}, suggesting the fault is loaded toward failure between megathrust earthquakes.},
