Description:

This paper describes a replicable approach for characterising interrelations between natural hazards. This characterisation is one step within a multi-hazard risk assessment. The focus of this paper is Guatemala, a context exposed to multiple, interrelating natural hazards. Diverse evidence of natural hazards and natural hazard interrelationships is used to construct matrices of hazard interrelationships for Guatemala at national and sub-national scales. Evidence types considered in this work include (a) internationally accessible literature, (b) locally accessible civil-protection bulletins, (c) field observations, (d) stakeholder interviews, and (e) a stakeholder workshop. We believe that hazard interrelationship matrices are scalable and the approach used to develop these can enhance cross-disciplinary and cross-institutional dialogue on multi-hazard interrelationships, their likelihood, and potential impacts.

Technical Considerations:

Other examples of hazard interrelationship matrices for different scales and contexts exist in the open-access, peer-reviewed literature.
