Communicating the status of volcanic activity in New Zealand, with specific application to caldera unrest
Paper number: 4618
This research focuses on recognising changes at a caldera volcano when it begins to show signs of unrest, and the communication of this information using the Volcanic Alert Level system.
Paper number: 4616
The attenuation of eruption ashfall thickness with distance is a complex response to a large number of eruptive and environmental factors. The journal paper presents a rigorous statistical method...
Paper number: 4614
The models produced in this study give new insights into the eruption of lava domes, and the evolution of the porosity and permeability within. Understanding the processes of dome growth, bubble...

An examination of seismic characteristics before, during and after small phreatic eruptions at Mt. Ruapehu volcano, New Zealand.
Paper number: 4612
New radiometric ages determined on basalt lava flows at Kaikohe and Bay of Islands in Northland, New Zealand demonstrate that volcanoes were active as recently as about 70,000 and 40,000 years ago,...
Time-varying seismic velocity in New Zealand's volcanic regions: Comparisons between shear wave splitting and surface wave noise correlations
Paper number: 4611
Techniques used in this study provide substantial steps toward the ultimate goal of eruption early-warning based on near-real time seismic tomography.
Paper number: 4610
Borehole seismometers were installed on Mt. Ruapehu volcano to examine seismic waveforms of earthquakes and explosions recorded on these and other GeoNet and portable seismometers.
Paper number: 4609
This preliminary study has provided some important parameters, but has equally shown that a more complete, longer term study is needed to provide the type of information needed by planners to...
Paper number: 4608
This study describes the findings following comparison of computer simulated waves to real earthquake waves observed from repeating low-frequency earthquakes produced by the Ngauruhoe volcano from...
Paper number: 4607
This study used geological techniques to measure the gas pressure of inclusions within quartz crystals at Mt Ngauruhoe.
