Implications of Thermal Weakening and Magma Compressibility for Volcano Monitoring
Journal 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.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

Water Resources Research, Volume 62, Issue 9, September 2026.Abstract Although geothermal energy is a low‐carbon resource, some powerplants can coproduce and release CO2 ${\text{CO}}_{2}$, which is then subject to emissions monitoring and sometimes financial penalty. Accurate attribution of these emissions is difficult because exploitation of the reservoir alters hydrological flows that in turn modify surface ...

, 2023 Two caldera forming ignimbrite eruptions of Taupō volcano (New Zealand) are among the most violent, powerful, and complex known Late Quaternary volcanic eruptions on Earth. The >530 km3 (dense rock equivalent [DRE]) ~25.5 ka Ōruanui, and 35 km3 (DRE) 232

Conspecific Negative Distance‐Dependence and New Zealand Podocarp Forest Dynamics
Austral Ecology, Volume 51, Issue 9, September 2026.ABSTRACT The Janzen‐Connell hypothesis proposed that conspecific negative density or distance dependence (CNDDD) helps maintain the species richness of tropical rainforests through the action of specialist natural enemies that suppress conspecific recruitment beneath canopy trees.

Seismic Anisotropy And Time-Frequency Analyses During Taupō's 2019 Unrest
, 2022 The currently active Taupō volcano (with its most recent eruptive event at ∼ 1.8 ka) was responsible for Earth’s youngest supereruption at 25.5 ka. In the past 141 years, 21 unrest events have been observed in records of seismicity, crustal deformation ...

A Microphysical Model for Predicting Magma Fragmentation
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Explosive volcanic eruptions occur when coherent bubbly magma breaks apart in a process called “fragmentation.” Accurate conceptual and numerical models of fragmentation are a pre‐requisite for prediction of eruption explosivity. However, existing models, which neglect bubble‐scale magma physics, agree poorly with new experimental evidence ...

A Dendrogeochemical Study of Kauri & The 232 Ce Taupō Eruption
, 2021 Full Text is available to authenticated members of The University of Auckland only.The exact date of the devastating Late Holocene Taupō eruption has been debated for decades with the currently accepted date set at 232 +/- 10 years Common Era (CE). This

Implications of a Supervolcano’s Seismicity
, 2020 Last year’s rumblings beneath New Zealand’s Taupō supervolcano, the site of Earth’s most recent supereruption, lend new urgency to research and outreach efforts in the ...
