Megathrust ruptures and the ensuing postseismic deformation cause stress changes that may induce seismicity on upper plate crustal faults far from coseismic rupture area. In this study, we analyze seismic swarms occurred in north Ecuador area of Esmeraldas, beginning two months after 2016 Mw 7.8 Pedernales, megathrust earthquake. The Esmeraldas region is 70 km Pedernales a separate segment subd...
