In this poster, utilising the core Project AF8 Alpine Fault earthquake scenario, we detail hazard exposure, impacts, and recovery of interdependent critical infrastructure networks across the energy, transportation, water & waste, and telecommunications sectors across the South Island of New Zealand. Asset failures are simulated across each individual network, based on shaking intensities, exposure to co-seismic hazards and estimated component fragilities, which have been further refined and validated through expert elicitation. Network disruptions are then propagated across an interdependent network framework to quantify and delineate the spatial reach of both direct and indirect failures. By incorporating recovery strategies, temporal changes in service levels are quantified to offer insights into expected interdependent network performance and the possible disconnection of communities from the nationally connected networks, otherwise not apparent when studying each infrastructure in isolation.
