Volcanic Eruptions Reorganize Climate Teleconnections: Detection via Riemannian Covariance Fingerprinting

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Standard detection and attribution of volcanic forcing targets spatial temperature anomalies. We show that the covariance structure of climate variability carries an independent volcanic fingerprint. Applying tangent‐space regression on the symmetric positive definite manifold SPD(8) to 40 years of eight teleconnection indices, we detect ...

Bathymetry Prediction With SWOT Gravity Anomaly Using Machine Learning Methods: Paper 1–Model Development

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Only one quarter of the global ocean floor has been directly surveyed; the remaining three quarters are inferred from satellite altimeter‐derived gravity data using techniques developed in the 1990s. These classical methods correlate gravity anomalies with known depths and extrapolate bathymetry in unsounded regions.

Evaluation of Pelletized Artificial Geopolymer Aggregate Manufactured From Volcano Ash [PDF]

open access: yes, 2013
This paper introduced the new pelletized artificial geopolymer aggregate made from volcano ash. This is one of the effort to diminish the high quantity of volcano mud from East Java, Indonesia, that become a major issue since May 29, 2006 when it ...

Sedimentary and volcano-tectonic processes in the British Paleocene Igneous Province: a review [PDF]

open access: yes, 2009
Research on the British Paleocene Igneous Province (BPIP) has historically focused on the emplacement, chemistry and chronology of its elaborate central intrusive complexes and lava fields.

Along‐Strike Variations in Sub‐Arc Melting Beneath the Alaska Peninsula Revealed by P‐Wave Attenuation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The diverse volcanic activity in the Alaska Peninsula section of the Alaska‐Aleutian subduction zone is presumably caused by substantial variations in mantle wedge melting or trans‐crustal processes beneath the arc. In this study, we investigate sub‐arc melting beneath the Alaska Peninsula by measuring P‐wave attenuation, as attenuation is ...

Registration of the atmospheric effect of the Hunga Tonga volcano eruption

open access: yesSolar-Terrestrial Physics
The paper presents the results of recording of acoustic waves, caused by the Hunga Tonga volcano eruption in the South Pacific Ocean on January 15, 2022, in Eastern Siberia at a distance of about 11230 km from the eruption.

Extending Māori Concepts in Secondary School Geography

open access: yesNew Zealand Geographer, Volume 82, Issue 2, August 2026.
ABSTRACT Secondary school geography brings together tāngata (people) and whenua (land), the central concepts of te ao Māori (the Māori world). Therefore, geography is ideally placed to respond to calls for mātauranga Māori (Māori knowledge) to gain “equal status” with Western knowledge.

How pro-poor is the selection of seasonal migrant workers from Tonga under New Zealand's recognised seasonal employer (RSE) program? [PDF]

open access: yes, 2008
Temporary migration programs for unskilled workers are increasingly being proposed as a way to both relieve labour shortages in developed countries and aid development in sending countries without entailing many of the costs associated with permanent ...

Investigating the Magma Reservoir of Taupō Volcano Using Receiver Functions

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Taupō Volcanic Zone (TVZ), one of the most active volcanic systems globally, poses significant hazards. To improve our understanding of crustal structure and implications for hazards, we apply P‐to‐S receiver function analysis, supplemented by S‐to‐P for validation, to temporary seismic network data surrounding Taupō volcano. This provides
