A new consistent and high-precision earthquake catalogue for the Taupō Volcanic Zone, New Zealand

open access: yesSeismica
The Taupō Volcanic Zone is a ~300 km long, volcanically active region in the North Island of Aotearoa New Zealand. As well as hosting numerous active volcanoes, it is also one of the most seismically active parts of the country.

Inferring the effects of compositional boundary layers on crystal nucleation, growth textures, and mineral chemistry in natural volcanic tephras through submicron-resolution imaging

open access: yesFrontiers in Earth Science, 2016
Crystal nucleation and growth are first order processes captured in volcanic rocks and record important information about the rates of magmatic processes and chemical evolution of magmas during their ascent and eruption.

Seismic Swarms Occurrence Rate and b-value Mapping at Taupo Volcanic Zone

open access: yesSeismica
We analyze the seismicity of the Taupō Volcanic Zone (TVZ) over a 17-year period (2007-2024) using a swarm-informed ETAS model and high-resolution b-value mapping.

Late Pliocene–Quaternary Arc Volcanism at the Southern Limit of the Hikurangi Subduction Zone: Revised Chronology of the Taranaki Peninsula, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Igneous centres across the Taranaki Peninsula represent the southwestern limit of arc volcanism associated with the Tonga–Kermadec–Hikurangi subduction system. Taranaki Maunga, the youngest and largest of three andesitic stratovolcanoes, dominates the geomorphology of the Taranaki Peninsula along with the eroded remnants of the Kaitake and Pouakai ...

Utilizing supercritical geothermal systems: a review of past ventures and ongoing research activities

open access: yesGeothermal Energy, 2017
Supercritical geothermal systems are very high-temperature geothermal systems that are located at depths near or below the brittle–ductile transition zone in the crust where the reservoir fluid is assumed to be in the supercritical state, that is for ...

CyberShake NZ: Probabilistic Seismic Hazard Analysis in New Zealand Using Physics‐Based Ground‐Motion Simulations

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
This study presents the computational components and workflow developed to conduct probabilistic seismic hazard analysis (PSHA) in New Zealand (NZ) using physics‐based ground‐motion simulations, referred to as “CyberShake NZ.” Semi‐automated procedures generate multiple realizations of kinematic rupture models, create rupture‐specific velocity models ...

Understanding Degassing Pathways Along the 1886 Tarawera (New Zealand) Volcanic Fissure by Combining Soil and Lake CO2 Fluxes

open access: yesFrontiers in Earth Science, 2019
CO2 flux measurements are often used to monitor volcanic systems, understand the cause of volcanic unrest, and map sub-surface structures. Currently, such measurements are incomplete at Tarawera (New Zealand), which erupted with little warning in 1886 ...

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited due to methodological differences across programs, taxonomic ...

Implications of Thermal Weakening and Magma Compressibility for Volcano Monitoring

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Magmatic intrusion and volcanic deformation are traditionally approximated with an inflating cavity in an elastic halfspace. Various analytical models predict surface displacement as a function of pressure or volume change, depth, and elastic crustal properties.
