Lifeline networks are the infrastructure and critical services needed for everyday life. Lifeline network failure has wide reaching impacts on residents, businesses, other critical services and, in a disaster, rescue and recovery. Currently there is limited research on the impact natural hazard events have on these systems and the flow on effects from their failure. To estimate the true impact of lifeline network disruption during a disaster, this study is developing a better understanding of network behaviour, interconnectedness and exposure to potential natural hazards.

Research questions being investigated include:

  • What portion of contingent business interruption loss is caused by the failure of lifeline network infrastructure and is this loss currently insured?
  • Can the interconnectedness of networks lead to a cascade of failures? 
  • What influences network recovery and how long can it take to rebuild?
  • How long can the impacts of a natural hazard event last and what is the cost of long term network disruption?
  • What scenarios could generate a potential catastrophic disruption in the future?
