Abstract: The 2014 Iquique event was not the earthquake that had been expected to fill the regional seismic gap; given that significant sections of the northern Chile subduction zone have not ruptured in almost 150 years, it is likely that future megathrust earthquakes will occur south and potentially north of the 2014 Iquique sequence.
