Project Title: Robust volcanic eruption forecasts: leveraging magmatic speedometry into geophysical monitoring

The key question asked of a volcano monitoring agency is “When will the volcano erupt?” While it is possible to determine whether a volcano is in a state of unrest, it is very difficult to forecast an imminent eruption based on geophysical monitoring signals alone. We will use petrography and geochemistry to decipher magmatic processes that are preserved within erupted material, as crystals and volcanic glass or groundmass reflect a history of growth within a variable (pressure, temperature, chemical, etc.) magmatic environment. We have recently demonstrated that these magma-speedometric methods allow the quantification of rates and timing of events leading to former explosive eruptions, as well as informing the geometry of the respective plumbing systems. In this project we will extend these insights to effusive eruptions, providing geophysical monitoring experts with knowledge about how the entire subvolcanic plumbing system operates. We will combine this field-leading knowledge with seismic and ground deformation observations that signal magma movement at depth. Building models will enhance scientific understanding of how seismicity and deformation are modulated by variations in volume, depth, and conduit geometry during magma ascent, and how these signals change over time as magma ascends from great depth to the surface. High-resolution geochemical information gained from deposits of previous eruptions will provide the boundary conditions for these models. Combining the models with future real-life geophysical observations during periods of volcanic unrest will allow rapid interpretation to identify timing, size, and style of potential eruptions. This method will be directly applied to monitoring of New Zealand’s volcanoes and incorporated into the GeoNet project. The outcomes of this work will protect the lives of people and the long-term livelihoods of stakeholders in volcanically active areas.

Project Title: He Tatai Whenua: A Te Ao Maori landscape classification

Our research will synthesize a Te Ao Maori landscape classification that can be directly integrated with existing geographical information systems (GIS). We will produce the first indigenous peoples, or Maori metric based Landscape Classification for New Zealand. Despite Maori expert elicitation, or interpretation, of landscape features being well recognised, coherent representation and display of this knowledge is significantly underdeveloped. Data of this kind is still treated as anecdotal or qualitative and, as a result, lacks impact in environmental management and decision-making. In stark contrast, the underlying descriptors and datasets used to classify NZ's environment for decision-making are all displayed in advanced GIS systems utilising cutting edge technology (e.g. geology (Qmap), soils (SMap), bio-diversity (Landcover Database/LENZ), and land use/capability (NZ Land Resource Inventory)). Many of the fundamental methods used to create these datasets are based on frameworks and criteria created through quasi-quantitative methods with no inclusion or recognition of matauranga Maori. This will be achieved through three components: 1. Development of Maori landscape classification criteria based on matauranga Maori, tikanga, kaitiakitanga and tohu taiao from leading Maori academics and Iwi partners 2. Generation of the first Maori Landscape Classification GIS (MLC-GIS) and database using new IT, GIS, remote sensing techniques and mathematical methods to visualise landscapes based on the developed criteria 3. Application of the MLC-GIS alongside existing environmental databases in new catchment management strategies Our research will use the Manawatu catchment to develop the protocols required to extend the proposed Maori Landscape Classification GIS to the whole of NZ. Globally this will be the first time such a dataset will be created. Additionally, new geospatial visualisation methods will be developed that will have significant impact.
