Differential Mountain‐Building in the South Tian Shan Revealed by Multi‐Spatiotemporal Foreland Deformation

open access: yesTectonics, Volume 45, Issue 2, February 2026.
Abstract Understanding how spatially variable mountain‐building processes proceed within large intracontinental orogens provides critical insights into continental tectonics and regional paleoenvironmental evolution. Here, we address this issue in the central South Tian Shan (cSTS), a key transitional segment between the well‐studied eastern and ...

Seismic Velocity Variations, Ground Deformation and the Role of Fluids During a Low‐Energy Seismic Swarm

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract On March 9th $9\mathrm{th}$, 2023, three small earthquakes (3.8≤Mw≤4.5) $(3.8\le {M}_{w}\le 4.5)$ occurred near Umbertide (Central Italy), within 4 hours. Analyzing seismic ambient noise in the frequency band 0.1–1 Hz from six seismometers within 20 km of the Mw 4.5, we detect a significant drop in seismic velocity at the time of occurrence of

Seismological Evidence of Multiple Crustal Magma Reservoirs Beneath Mt. Wrangell in Southcentral Alaska

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Recent studies have challenged the classical view of magma chambers as ephemeral, melt‐rich bodies confined to shallow depths beneath arc volcanoes at subduction zones. Instead, increasing evidence supports the existence of long‐lived, vertically extensive magmatic systems with persistent partial melts within the crust. Nevertheless, the depth

Abnormally Large Magma Flux Does Not Lead to Eruption in Subduction Zone Calderas: The 2022–2023 Episode of Uplift of Aniakchak Crater (Aleutians)

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Observations of ground deformation provide insights on the triggering mechanisms of eruptions. At Aniakchak Crater (Aleutians) InSAR measured ∼ ${\sim} $72 cm of uplift in less than 7 months between 2022 and 2023. The uplift can be explained by the inflation of a point pressure source at a depth of 3.2 km.

Tracking Subsurface Changes via Frequency Shifts in Volcanic Tremor Spectral Lines: Observations From Mt Etna

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Episodes of volcanic tremor provide valuable insights into the dynamics of subsurface processes at active volcanoes. Previous studies have suggested that evolving tremor properties may relate to changes in the stress conditions of the plumbing system. However, a strong causative link has remained elusive.

Full‐Wave SKS Splitting Intensity Tomography Suggests Depth‐Dependent Upper Mantle Fabrics and Anisotropy Beneath Alaska

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Alaska's tectonic complexity makes it ideal for probing upper mantle deformation. We present a 3D shear‐wave anisotropy model obtained by inverting 7,985 SKS splitting intensity measurements from 261 broadband stations using 941 events from 2000 to 2023.

Crustal Flow‐Driven Plateau Growth and Expansion Front in NE Tibet: Insights From High‐Resolution Attenuation Tomography With High‐Density ChinArray Lg Data

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Northeastern (NE) Tibet, as the front of plateau growth, widely absorbs northeastward extrusion, leading to significant uplift and forming a basin‐mountain tectonic framework. However, it remains unclear how the crust of NE Tibet deformed in response to the far‐field effects of the India‐Eurasia collision.

Supershear Transitions and Bilateral Asymmetric Rupture of the 2025 Sagaing (Myanmar) Earthquake Revealed by Geodetic and Seismic Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Sagaing Fault (SF) accommodates major plate motion in Myanmar, yet large earthquakes along it have rarely been captured by modern geodetic and seismic observations. The 2025 Sagaing earthquake generated an exceptionally long rupture (∼535 km), offering a rare opportunity to investigate rupture dynamics along continental transform fault. We
