  abstract = {{R}epeating earthquakes repeatedly rupture the same seismic asperity and are strongly linked to aseismic slip. {H}ere, we study the repeating aftershocks of the {A}pril 16, 2016 {M}-{W} 7.8 {P}edernales earthquake in {E}cuador, which generated a large amount of afterslip. {U}sing temporary and permanent stations, we correlate waveforms from a one-year catalog of aftershocks. {W}e sort events with a minimum correlation coefficient of 0.95 into preliminary families, which are then expanded using template-matching to include events from {A}pril 2015 to {J}une 2017. {I}n total, 376 repeaters are classified into 62 families of 4-15 events. {T}hey are relocated, first using manual picks, and then using a double difference method. {W}e find repeating earthquakes during the whole period, occurring primarily within large aftershock clusters on the edges of the areas of largest afterslip release. {T}heir recurrence times, shortened by the mainshock, subsequently increase following an {O}mori-type law, providing a timeframe for the afterslip's deceleration. {A}lthough they are linked temporally to the afterslip, repeater-derived estimates of slip differ significantly from {GPS}-based models. {C}ombined with the fact that repeaters appear more spatially correlated with the afterslip gradient than with the afterslip maxima, we suggest that stress accumulation at the edge of the afterslip may guide repeater behavior.},
