(Color online) Prefailure dynamics is governed by pathway redundancy. Evolution of the pathway redundancy \(p_{min}\) for (a) D1 and (b) D2. Inset shows spatial distribution of links that leave \(\mathcal {P}\) but remain in \({\mathcal {N}}\) (no access), enter \(\mathcal {P}\) (replacement), unchanged and damaged links in \(\mathcal {P}\) due to rerouting. Black arrow marks the general location of \({\mathcal {C}}\). Dashed vertical line marks the stage at peak load.
