Resilience to New Zealand’s Hazard Spectrum
Prof Mark Bebbington
New Zealand has a complex natural hazard environment, and it is important that we understand those hazards so that we can be prepared for their effects. The Resilience to New Zealand’s Hazard Spectrum programme is generating new knowledge about interacting hazards, and a set of fit-for-purpose hazard tools and solutions for nationally consistent delivery of risk information. These tools will underpin development of resilience solutions across all relevant natural hazard types.
Specifically, this programme is developing new frameworks and methods for consistent expression of all parts of the hazard spectrum, from low-magnitude/high-frequency to high-magnitude/low-frequency cases. These are being utilised with hazard and resilience-relevant knowledge by a wide range of community groups, governance and private agencies and other science stakeholders. The programme also takes into account the dynamic shifts that may occur along the hazards impact spectrum, due to factors including: climate change, societal change, and geological activity.
Franz Josef is vulnerable to a range of hazard events, and the community needs to ensure it is resilient enough to live through, and prosper after, any future major hazard event.

It is hard to quantify the dynamic interactions that cause multi-hazard events, meaning that we don’t have a good understanding of how they will play out.
PhD researcher Alex Dunant is modelling multi-hazard impact scenarios to increase our understanding and better inform communities and emergency services.
