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 ...

Seismic Radial Anisotropy of the Southern Tibetan Rifts From Ambient Noise Adjoint Tomography: Basal Shear and Localized Crustal Weak Zones Promote Rifting

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract North–south‐trending rifts in southern Tibet record E–W extension within the Tibetan Plateau, closely linked to high gravitational potential energy from collisional thickening and northward underthrusting of the Indian lower crust. To reveal how basal shear is transmitted upward and controls rifting, we use ambient noise adjoint tomography ...

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones.

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...
