What are Cascading Disasters?

David Alexander, Gianluca Pescaroli (corresponding) (2019)

Cascades have emerged as a new paradigm in disaster studies. The high level of dependency of modern populations on critical infrastructure and networks allows the impact of disasters to propagate through socio- economic systems. Where vulnerabilities overlap and interact, escalationpoints are created which can create secondary effects with greater impact than the primary event. This article explains how complexity can be categorised and analysed in order to find those weak points in society that enable cascading impacts to develop. Scenarios can be used to identify critical dependencies and guide measures designed to increase resilience.Experience suggests that many potential impacts of cascading disasters remain uninvestigated, which provides ample scope for escalation of impacts into complex forms of crisis.

Review text

The paper is very interesting.

It introduces an original treatment of Cascading Disasters.

The general aspects of the method proposed for the Cascading disasters evaluation are well described.

The theoretical algorithms description is not reported in the paper.

References to predictive evaluation models of Cascading effetcs would be useful in order to define a complete framework of the topic.

Hi Giulio, thank you for your feedback. That's a good idea. We will add references to some methodologies referring to the papers of the special issue on IJDRR.
