  abstract = {{T}he heterogeneous seafloor topography of the {N}azca {P}late as it enters the {E}cuador subduction zone provides an opportunity to document the influence of seafloor roughness on slip behavior and megathrust rupture. {T}he 2016 {M}-w 7.8 {P}edernales {E}cuador earthquake was followed by a rich and active postseismic sequence. {A}n internationally coordinated rapid response effort installed a temporary seismic network to densify coastal stations of the permanent {E}cuadorian national seismic network. {A} combination of 82 onshore short and intermediate period and broadband seismic stations and six ocean bottom seismometers recorded the postseismic {P}edernales sequence for over a year after the mainshock. {A} robust earthquake catalog combined with calibrated relocations for a subset of magnitude >= 4 earthquakes shows pronounced spatial and temporal clustering. {A} range of slip behavior accommodates postseismic deformation including earthquakes, slow slip events, and earthquake swarms. {M}odels of plate coupling and the consistency of earthquake clustering and slip behavior through multiple seismic cycles reveal a segmented subduction zone primarily controlled by subducted seafloor topography, accreted terranes, and inherited structure. {T}he 2016 {P}edernales mainshock triggered moderate to strong earthquakes (5 <= {M} <= 7) and earthquake swarms north of the mainshock rupture close to the epicenter of the 1906 {M}-w 8.8 earthquake and in the segment of the subduction zone that ruptured in 1958 in a {M}-w 7.7 earthquake.},
