  abstract = {{T}he 2016 {M}w 6.1 {P}arina earthquake ruptured a shallow-crustal normal fault within the high {A}ndes of south {P}eru. {W}e use high-resolution {DEM}s and field mapping of the surface ruptures generated by the earthquake, in combination with co-seismic and post-seismic {I}n{SAR} measurements, to investigate how different features of the geomorphology at {P}arina are generated by the earthquake cycle on the {P}arina {F}ault. {W}e systematically mapped 12 km of {NW}-{SE} trending surface ruptures with up to similar to 27 cm vertical displacement and similar to 25 cm tensional opening along strike, separated by a gap with no observable surface ruptures. {C}o- and post-seismic {I}n{SAR} measurements require slip below this gap in surface ruptures, implying that surface offsets observed in paleoseismic trenches may not necessarily be representative of slip at seismogenic depths, and will typically yield an underestimate of paleo-earthquake magnitudes. {T}he surface ruptures developed along 10-20 m high cumulative scarps cutting through late {Q}uaternary fluvio-glacial deposits and bedrock. {T}he 2016 {P}arina earthquake did not rupture the full length of the late {Q}uaternary scarps, implying that the {P}arina {F}ault does not slip in characteristic, repeat earthquakes. {A}t {P}arina, and across most of the {P}eruvian {A}ltiplano, normal faults are most-easily identified from recent scarps cutting late {Q}uaternary moraine crests. {I}n regions where there are no recently-deposited moraines, faults are difficult to identify and lack time constraints to quantify rates of fault slip. {F}or this reason, current fault maps may underestimate the seismic hazard in the {A}ltiplano.},
