Abstract
When Hurricane Maria struck the island of Puerto Rico on September 20, 2017, it devastated the island’s aging power systems infrastructure and inflicted an island-wide power outage that left Puerto Rico in total darkness for an entire week before the system slowly started to recover. This unprecedented failure of the critical power systems infrastructure exacerbated the failure of other critical infrastructures or lifeline systems of the island. This research explores and quantifies the relationships or interdependencies that exist between the power systems and other critical infrastructure systems by investigating the post-hurricane recovery data of these lifeline systems. Subsequently, the research validates the discovered interdependencies using critical infrastructure systems recovery data following Hurricane Fiona on September 18, 2022. The findings indicate that strong interdependency relationships exist between power systems and some of the critical infrastructure systems whereas other critical systems display weak associations with the power systems infrastructure. Focusing efforts to improve the resiliency of the power systems by targeting the post-disaster recovery phase, increases the resiliencies of other critical infrastructure systems strongly associated with power systems, and, thereby, leads to a more resilient community in disaster-prone areas.
