Shell‐Dense Island Off Culasawani, Vanua Levu Island, Fiji: Midden or Muddle?

open access: yesGeoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT Investigations of a 3000 m2 shell‐dense island surrounded by mangroves off the coast of Culasawani, a very lightly inhabited part of northern Vanua Levu Island in Fiji, suggest it is likely to be a ‘midden island’ rather than a (tsunami) wave deposit.

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

open access: yesNew 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 ...

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

open access: yesEarth 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 ...

Application of Singular Spectrum Analysis (SSA) for Delineating Geomagnetic and Lithospheric Signatures Associated With M7.6 Japan Earthquake

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract In this paper, Singular Spectral Analysis (SSA) is applied to the geomagnetic field to delineate signatures from different sources, such as geomagnetic variability and lithospheric processes. We performed SSA on the Y component of the Swarm satellite magnetic field By during the period from September 2023 to January 2024. Eigen values obtained

Effectiveness of Ecosystem‐Based Coastal Defenses Against Flooding

open access: yesEarth's Future, Volume 14, Issue 3, March 2026.
Abstract Coastal flooding is growing substantially as storms increase and sea levels rise rapidly due to climate change. It is therefore important to find safe and sustainable ways to protect coastal communities against this growing risk. However, the effectiveness of traditional coastal defenses (hard seawalls) (HS) is being questioned due to concerns
