Seismic Site Effects in Owhiro Bay Quarry, Wellington: Field Observations and Numerical Modelling

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Local topography and geology are well known factors affecting the intensity of seismic shaking. We have investigated the seismic site effects at a site of the Owhiro Bay Quarry in Wellington, New Zealand, using instrumental records and numerical models.

Newly Discovered Active Faults in the Wairarapa Valley: Implications for Multi‐Fault Rupture and Kinematics in the Southern North Island, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Active fault locations and constraints on the timing and size of earthquakes are important for understanding and mitigating seismic hazard in Aotearoa New Zealand. However, historical and instrumental records are too short to provide these data on most earthquake‐generating faults. Light detection and ranging (lidar) data provide us with the ability to

New Zealand Geological Timescale 2025

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

Detecting Snow Avalanche Activity Using Infrasound: Hooker Valley, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Snow avalanches pose considerable hazards to people and infrastructure in alpine environments. Traditional avalanche monitoring relies on meteorological data and visual observations, which can be limited in scope and timeliness. Infrasound offers a promising complementary monitoring tool by detecting the low‐frequency sound waves generated by ...

Forgetting and Remembering: Kenneth Cumberland and Soil Erosion in New Zealand, 1940s to 2020s

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 1, March 2026.
The speed and scale of landscape transformation in New Zealand was almost immediately apparent to British geographer Kenneth Cumberland on his appointment to Canterbury University College in 1938. His efforts culminated in the nationally and internationally well‐regarded book ‘Soil Erosion in New Zealand: A Geographical Reconnaissance (1944a)’, which ...

Detection and Modeling of the Effect of Large Earthquakes in GRACE/GRACE‐FO Mascons

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The usefulness of Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On (GRACE/FO) data products for ocean studies remains limited in a few areas, where large gravity signals from the 2011 Japan earthquake and three major earthquakes in the Andaman‐Sumatra area (in 2004, 2007, and 2012) obscure vastly smaller signals of interest ...

Subduction Zone Magnetism: The Influence of Metamorphism and Serpentinization in the Mantle Wedge

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction zone magnetic anomalies have previously been used to infer their thermal structure assuming a uniformly serpentinized mantle carries a homogeneous, isotropic magnetization. However, seismic tomography, geological observations and numerical modeling provide increasing evidence for a non‐uniformly serpentinized mantle wedge that may ...

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part I Theory

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Pattern formation in geological materials is commonly described using analogies to Turing‐type reaction–diffusion systems, yet a unifying thermodynamic explanation remains elusive. Here we develop a multiscale, thermodynamically consistent framework for pattern‐forming instabilities in porous media undergoing coupled thermo–hydro–mechanical ...
