“Physical volcanology and multi-hazard analyses of Mt. Ruapehu for the late Holocene”

Research objectives

Volcanic eruptions are amongst the most lethal natural hazards on Earth. In New Zealand, these hazards pose enormous potential threat to life. Their impacts have the potential to induce permanent change to infrastructure, tourism and primary industries. Despite previous research, one of the key risk dimensions of volcanic eruptions must still be addressed – their dynamic evolution during the course of an eruption sequence, leading to multiple, and strongly interdependent, hazards. This PhD research will develop the first multi-stage multi-hazard eruption model, using the late Holocene eruption sequence of Mount Ruapehu as the benchmark. Quantitative data of the order, style and magnitude of hazards will help to identify fundamental recurrence, progression and cascading patterns in hazards, as well as their likelihood and uncertainties. The data and analyses comprised in this model will form the base to develop hazard tools for stakeholders

The second part of this research will target a selection of eruptive sequences to determine the underlying processes and causes that influence the main characteristics of an eruption sequence (e.g. style and order of events, magnitude, recurrence intervals). Here, geochemical and physical volcanology methods will be applied to characterise i.a. magma storage and eruption dynamics. These data will be combined with existing models and will improve understanding of eruption processes at andesitic volcanoes.
