Description:

This paper presents a broad overview, characterisation, and matrix visualisation of the interrelationships between 21 natural hazards, drawn from six hazard groups (geophysical, hydrological, shallow Earth, atmospheric, biophysical, and space hazards). Interrelationships considered are primarily those where a primary hazard triggers or increases the probability of secondary hazards occurring. The paper includes a suite of additional matrix visualisations which characterise these interrelationships, including (a) exploring how well we can characterise secondary hazards, given information about the primary hazard, (b) determining the spatial overlap and temporal likelihood of triggering relationships occurring, and (c) examining the relationships between primary and secondary hazard intensities for hazard interrelationships. This work has since been adapted into a range of context-specific multi-hazard interrelationship matrices (e.g., for Guatemala, Istanbul, Nairobi, and Kathmandu), all available in the open-access peer-review literature.
