Volcanic eruptions can produce many hazards which can impact society yet many cities, including Auckland, are built on or near active volcanoes. Auckland rests on the Auckland Volcanic Field (AVF), an active volcanic field of 500km2, including 53 volcanic centres, which poses a significant risk to Auckland and its residents. Volcanic eruptions are inherently multi-hazard, yet the majority of volcanic impact assessments focus on a single hazard or ignore any interactions between multiple hazards. A multi-volcanic hazard impact assessment considers the impacts of more than one volcanic hazard occurring at a given location and time period. The process recognises that there are significant interactions between volcanic hazards and the differing damage mechanisms of these hazards. Multi-volcanic hazard impact assessments can provide greater understanding of the impacts of interacting hazards, for which there are many applications. This research will focus on the impacts to timber framed residential buildings in the Auckland Volcanic Field and will be used to improve the quantitative assessment of volcanic hazard impacts by considering the effects of multiple volcanic hazards impacting buildings in different sequences over various timescales. Research will be completed using empirical experiments to simulate ash fall and volcanic ballistic impacts to residential buildings. This research will include testing of a timber-framed roof structure and will be complimented by post-eruption impacts assessments, geospatial analysis and review of relevant literature. It will also investigate how multiple volcanic hazards can influence habitability of housing in Auckland. This research will contribute to improving volcanic risk assessment and resilience decision making for Auckland city and reduce the impact of a habitability crisis when the next Auckland Volcanic Field eruption occurs.
