Seismological data shows that the subduction zone seismogenic interface is composed of a network of simultaneously active, metres-thick faults, which influences afterslip propagation and earthquake rupture dynamics.

Using observations of double-difference relocated earthquakes in a local three-dimensional velocity model for Ecuador, a detailed image of seismicity is created, forming the base for more realistic models of earthquake rupture, slip and hazard in subduction zones.
