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

Dense magnetotelluric imaging of the Akan Caldera (Hokkaido, Japan): insights into its magma plumbing system and caldera-forming reservoir

Earth, Planets and Space
To investigate the magma plumbing system beneath the Akan Caldera (Hokkaido, Japan), we conducted broadband magnetotelluric surveys and imaged its three-dimensional resistivity structure to a depth of approximately 30 km.

The Stromboli geophysical experiment. Preliminary report on wide angle refraction seismics and morphobathymetry of Stromboli island (Southern Tyrrhenian sea, Italy)based on integrated offshore-onshore data acquisition (cruise STRO-06 R/V Urania) [PDF]

, 2007
The Stromboli geophysical experiment, performed to acquire onshore and offshore seismic data through a combined on-land and marine network, was finalized to reconstruct the seismic tomography of the volcano and to investigate the deep structures and the

Instrumental Artefacts Can Reverse Apparent Lightning–Climate Trends

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Lightning is an Essential Climate Variable, yet long‐term detection records may be compromised by changes in detection technology. Using more than three decades of Austrian lightning observations (1992–2024), we show that instrumental artefacts can reverse the apparent sign of lightning–climate trends.

Seismology in India: Colonial Geologists and the Raj, 1880-1910 [PDF]

, 2018
At the end of the nineteenth century, seismologists were trying to create a ‘universal’ seismology that could be applied worldwide. Applying the observational European techniques in various places across the world challenged scientists to reassess their ...

Tracing Mantle Upwellings Beneath Changbaishan/Mount Paektu: New Insights From Transition Zone Discontinuity Structure

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Intraplate volcanism in Northeast Asia, located in a distant back‐arc setting, challenges conventional models of mantle convection and volatile cycling. Using receiver function data from over 300 broadband stations, we image the mantle transition zone (MTZ) beneath the Changbaishan/Paektu volcano.

The Aurora Vent Field at the Transition From Magmatic Accretion to Tectonic Extension on Gakkel Ridge: Constraints From Microseismicity and Aeromagnetic Observations

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The Aurora hydrothermal vent field (AVF) is the first confirmed active vent system on the Arctic Ocean seafloor, located at the western end of the ultraslow spreading Gakkel Ridge. It marks a distinctive endmember among ridge‐axis hydrothermal systems, where volcanic construction and ultramafic influence co‐exist.
