Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Pulse‐like infrasound accompanying volcanic phenomena sometimes suggests interaction with water at the crater. We focus on pulse‐like infrasound observed at Semisopochnoi Island in the Aleutian Arc, Alaska, during the phreatomagmatic activity on 13 July 2021.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract The Eurasian Basin of the Arctic Ocean opened by ultraslow spreading along the Gakkel Ridge, yet crustal thickness has remained poorly constrained due to sparse seismic data. We present a new basin‐wide 3‐D gravity model, updated by the most comprehensive sediment thickness and seismic observations, offering the first systematic view of ...

New Insights Into the Cooling of the Oceanic Lithosphere From Surface‐Wave Tomographic Inferences
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract How oceanic plates cool and thicken with age remains a subject to debate, with several thermal models supported by apparently contradictory data. Combining a novel imaging technique that balances resolution and uncertainty with finite‐frequency surface‐wave measurements, we build tomographic model SS3DPacific to revisit the cooling style of ...

Deep Earthquakes Can Generate Larger Co‐Seismic Displacements Than Shallow Events
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract We report the counter‐intuitive observation that a deep earthquake can generate larger co‐seismic displacements than a shallow event across a broad region (e.g., >4° from epicenter). This finding is based on a detailed comparative GNSS analysis of the co‐seismic displacement observations from two MW 8.3 events—the 2013 598.1 km‐deep Okhotsk ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract The Laguna del Maule volcanic field in Chile has been uplifting at exceptional rates since 2007, offering a unique opportunity to examine the interplay between crustal deformation and magma dynamics. To understand this relationship, we integrate GNSS with local seismic observations from 2013 to 2024 to model the reservoir strain field ...

Tide‐Modulated Ocean‐to‐Earth Energy Conversion Quantified With Coastal Fiber Sensing
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Quantifying how incident ocean waves transfer energy into seismic surface waves along the nearshore is essential for understanding coastal hazards and Earth–ocean coupling, yet time‐resolved in situ estimates have been scarce. Here we use a beach‐deployed distributed acoustic sensing array co‐located with an ocean‐bottom node to directly ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.

Vertical Land Motion and Human Exposure Across India's Coastal Regions
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract In India, over 200 million people live within 100 km of the coastline, and many reside in low‐lying areas exposed to increasing flood risks associated with sea‐level rise. However, the role of vertical land motion (VLM)—particularly land subsidence—in shaping this coastal exposure remains poorly quantified. Here we present the first assessment

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Deep‐sea rare earth elements and yttrium (REY)‐rich sediments have attracted considerable attention since their discovery in 2011. However, the environmental factors controlling REY enrichment remain poorly understood, largely because paleoceanographic proxies are absent in pelagic clays.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.Abstract Nitrogen stable isotopes (δ15N) of ice core nitrate (NO3−) are often subject to diverse interpretations associated with changes in nitrogen oxide (NOx) sourcing, atmospheric reactions, and/or post‐depositional processes. Here, an ice core from Mont Blanc (French Alps) was analyzed to investigate the δ15N(NO3−) record over the past 1,000 years.
