Slip on the Peru megathrust Hugo Perfettini and colleagues show that the 2007 magnitude-8.0 Pisco earthquake in central Peru ruptured two asperities within a patch that had remained locked over the interseismic period, and triggered aseismic frictional afterslip on two adjacent patches. The most prominent patch of afterslip coincides with the subducting Nazca ridge, an area also characterized by a low interseismic coupling, which seems to have repeatedly acted as a barrier to seismic rupture propagation in the past. Aseismic slip accounts for as much as 50–70 per cent of the slip budget on the seismogenic portion of the megathrust in central Peru, and the return period of magnitude-8.0 earthquakes in the Pisco area is estimated to be 250 years. |
