This paper explores how critical infrastructure (CI) resilience can be improved through effective crisis communication between CI operators and members of the public. Drawing on academic and practice-based research into crisis and risk communication, as well as the results of 31 interviews conducted with key stakeholders from across Europe, the AESOP guidelines are proposed for enhancing the communication and information-sharing strategies of CI operators. These emphasise the importance of integrating both traditional and digital media into a multi-channel communication strategy that facilitates dialogue between CI operators and key stakeholders including emergency management organisations and representatives of local communities. The information-seeking behaviours of citizens should be evaluated by these organisations in order to ensure that this messaging reaches key demographics in disaster-vulnerable areas. This paper concludes by examining how post-disaster learning should be incorporated into a flexible framework for crisis and risk communication that manages public expectations about the time needed to restore services in the aftermath of large-scale incidents.
