Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract The mid‐tropospheric winter North Pacific storm track (NPST) underwent an interdecadal transition from weak to strong in the mid‐1980s and exhibited a significant intensification trend. Using climate model outputs, this study investigates the contributions of external forcing and internal variability to the NPST intensification.

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Volcano‐tectonic (VT) earthquakes generated during dike propagation provide useful constraints on stress changes in volcanic systems. During the 1998 pre‐eruptive unrest at Piton de la Fournaise, ∼600 VT earthquakes were recorded. Using manually picked first‐motion polarities and corrected station metadata, we calculated more than 400 high ...

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 ...

Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main eruptive phase, and secondary events hours later.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.Abstract Aerosol radiative effects are the largest uncertainty in anthropogenic forcing estimates due to challenges in accurately representing aerosol properties and aerosol‐cloud interactions. In this study, we implement the Advanced Particle Microphysics module (APM) into the Energy Exascale Earth System Model (E3SMv3) to represent evolving size ...

Large (∼80 km) Shield Volcanoes on the Moon Possibly Fed by Shallow Magma Reservoirs
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Large shield volcanoes are among the most prominent volcanic structures on terrestrial bodies. The Moon, while volcanically very active in the past and hosting various volcanic features, seems to lack such large shield volcanoes. Here, we report the identification of two lunar volcanic domes (Prinz‐Harbinger and Theophilus) with diameters ...

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

Very‐Long‐Period Seismic Signals During Lateral Dike Propagation at Piton de La Fournaise Volcano
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract We report a previously undocumented sequence of very long period (VLP) signals preceding the September 2022 eruption at Piton de la Fournaise. These events occurred during lateral magma propagation and exhibit quasi‐periodic sawtooth‐shaped displacement transients.
