The risk of consecutive disasters will increase due to growing exposure, the interconnectedness of human society and the increased frequency and intensity of non-tectonic hazard. While a large body of literature addresses multi-risk based on the spatial overlap between the exposure of different hazard types faced by one particular area, the temporal aspect of sequential hazards has been studied to a much lesser extent.
Yet, neglecting the residual risk from the impact of consecutive hazards can lead to a strong bias in the total risk. This study looks at the different implications of consecutive risk modelling on:
- the asynergies, the potential adverse effects, of DRR measures aimed at decreasing the risk of one hazard on the risk of another hazard;
- changing migration and displacement;
- changing wildlife populations.
This study was conducted in collaboration with Red Cross 510, British Geological Survey and Karlsruhe Institute of Technology.
