Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Volatile Conduits Beneath Vulcano Island (Italy) Revealed by High‐Resolution Nodal Local Earthquake Tomography During Volcanic Unrest

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Understanding shallow magmatic and hydrothermal systems at active volcanoes is essential for interpreting unrest and forecasting eruptions. We present the first high‐resolution three‐dimensional Vp $Vp$, Vs $Vs$, and Vp/Vs $Vp/Vs$ models of Vulcano Island, Aeolian Islands, Italy, derived from a dense nodal seismic network.

Preservation of Isolated Vesicles in Submarine Pumice and Implications for Submarine Slope Stability

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Pumice clasts from submarine eruptions contain abundant isolated vesicles that are completely encased in glass. As erupted clasts cool, gas inside isolated vesicles contracts, leading to low pressures inside those vesicles. Despite low pressures, isolated vesicles can be preserved in submarine pumice deposits to water depths of approximately 1–

Expanding OCO‐2's Volcanic Observation Record to the Low‐Intensity 2021 Fagradalsfjall and the Ninth Sundhnúkur Crater Row Eruptions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Since 2021, Iceland experienced 12 volcanic eruptions, all located on the Reykjanes peninsula. From these events, the 2021 Fagradalsfjall and the ninth Sundhnúkur crater row (16 July–5 August 2025) eruptions were detected by the Orbiting Carbon Observatory‐2 (OCO‐2).
