Short summary
We combined satellite radar and GPS data to model how the faults in El Salvador and nearby regions accumulate deformation. Motion across the central El Salvador Fault Zone is shared by several fault branches, while the offshore subduction zone appears to be weakly locked. These results improve the understanding of regional deformation and seismic hazard in Central America.
