Deep Seismic Tremors in the 2025 Santorini Seismo‐Volcanic Crisis Highlight Magmatic Feeding From a Mid‐Crustal Reservoir

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An intense seismic swarm started on 27 January 2025 in the Santorini‐Amorgos region and lasted for approximately 45 days. A widely observed seismic tremor on 14 February 2025 suggested a volcanic origin for the 2025 Santorini crisis. Here we present an in‐depth combined seismological analysis of the earthquakes and tremors that occurred during

An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

Rapid UAV‐ and Ground‐Based Magnetic Mapping of Subsurface Fractures During a Volcano‐Tectonic Crisis in Grindavík, Iceland

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We applied an integrated UAV‐ and ground‐based magnetometry workflow to map shallow subsurface fractures and cavities in the town of Grindavík during the 2023–2025 volcano‐tectonic crisis. Short‐wavelength linear and semi‐circular magnetic lows delineate open or partially open fractures and localized cavities, including features with no ...

Disentangling Anthropogenic Effects on Southern Hemisphere Circulation and Surface Climate: A Multi‐Model Large Ensemble Approach

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Southern Hemisphere (SH) circulation and surface climate changes are emerging in recent decades. For example, in most seasons, the SH Hadley cell edge and the eddy‐driven jet stream have shifted polewards, and the Southern Annular Mode (SAM) has trended towards its positive phase.

Unveiling the Shortwave Absorption Spectra of Alumina Aerosols: Radiative Implications for Solar Radiation Modification

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Alumina is proposed for Stratospheric Aerosol Injection (SAI)‐based solar radiation modification due to its presumed ability to scatter sunlight strongly while absorbing weakly. Alumina is assigned negligible solar shortwave absorption in climate models; this assumption is not validated owing to technological challenges in quantifying its weak

Lidar Ratios and Fluorescence Properties of Stratospheric Volcanic Sulfate

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract From January to June 2025, a stratospheric sulfate layer originating from the eruptions of the Ruang volcano in April 2024 could be observed with a multi‐wavelength Raman and fluorescence lidar over Leipzig, Germany. The aerosol‐optical depth of the stratospheric volcanic sulfate was <0.02 ${< } 0.02$, decreasing with time.
