Cascading And Linked Multi Hazards October 2013 The growing prevalence of cascading hazards and compound disasters underscores the need for a more comprehensive and integrated understanding of risk. Natural hazard impacts on industrial activities handling hazardous substances can result in severe cascading events such as fires, explosions, and toxic or radioactive releases. these so called natech accidents are often overlooked in regional and national disaster risk management plans.
Cascading And Linked Multi Hazards The unisdr (united nations office for disaster risk reduction, 2016) defines multi hazards as “events [that] may occur simultaneously, cascadingly, or cumulatively over time, considering the potential interrelated effects.”. This study introduces a new approach to multi hazard risk assessment, leveraging hypergraph theory to model the interconnected risks posed by cascading natural hazards. Despite increased research in "multiple hazards" and "cascading effects", there remains terminological ambiguity of the concepts. in this paper, we review the literature to explore how these. Despite increased research on ‘multiple hazards’ and ‘cascading effects’, ambiguity remains concerning terminology. this paper reviews the literature to explore how these two concepts are defined in relation to critical infrastructures and their vital societal functions.

In this context, multi hazards refer to situations in which at least two hazards occur simultaneously, in cascades or cumulatively, where hazards may be physically linked or independent but interact through their combined effects (undrr and isc 2020). The framework is illustrated with a multi hazard example close to the epicenter of the wenchuan earthquake, which involved a chain of hazards including slope failures, a large debris flow, river damming, and flooding. The infrarisk project proposes a multi hazard assessment methodology that considers both cascading events and co occurrences of interacting main hazards. this methodology is outlined in d’ayala et al. (2014). Hazards that are related in a systemic causal relationship and expressed in a sequence of secondary events in natural and human systems that lead to physical, environmental, social, or economic disruption, and where the resulting impact is significantly larger than under a single hazard event.
