Multiscale imaging of the 2016 Pedernales megathrust earthquake rupture zone offshore northern Ecuador. Analysis of the mainshock and seismic sequence after the earthquake reveal a segmented subduction zone primarily controlled by subducted seafloor topography, accreted terranes, and inherited structure. A range of slip behavior accommodates deformation including fast earthquakes, slow slip earthquakes, earthquake swarms, and repeating earthquakes. The 2016 main shock triggered both moderate to large earthquakes and earthquakes swarms north of the mainshock rupture in the vicinity of a patch of the subduction zone that ruptured in 1958 in a Mw 7.7 earthquake and the epicenter of the 1906 Mw 8.8 earthquake.
