A Lithospheric Drip Triggered Green and Colorado River Integration

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The integration of the Green and Colorado Rivers shifted the continental drainage divide of North America, marking a key event in the hydrological and biogeographical evolution of the continent. Sedimentological and stratigraphic evidence shows that for integration to occur, the Green River likely cut through the Uinta Mountains between 8 and ...

Experimental Verification of a Two‐Dimensional Inverse Method for Turbidity Currents Using a Deep Neural Network

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Turbidites have been widely studied as indicators of the occurrences and magnitudes of paleo‐tsunamis and paleo‐earthquakes. Inversion to estimate flow conditions from turbidites offers valuable insights into the magnitudes of paleo‐seismic and tsunami events.

Timing and Style of Tectonic Assembly and Exhumation of the McHugh Complex Within the Chugach‐Kodiak Accretionary Wedge, Alaska

open access: yesTectonics, Volume 45, Issue 2, February 2026.
Abstract Accretionary complexes are key archives of subduction zone processes, preserving records of forearc growth, deformation, and tectonic reorganization. The Chugach–Kodiak accretionary complex of southern Alaska records Jurassic to Cretaceous underplating at shallow to intermediate subduction conditions. The McHugh Complex, an imbricated sequence

Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

open access: yesTectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Expanding the Ichnofacies Model to Tidal Straits: Testing Predictions and Assessing Anomalies

open access: yesTerra Nova, Volume 38, Issue 1, Page 19-26, February 2026.
ABSTRACT Trace fossils are instrumental in facies analysis, but some depositional environments remain underexplored. Cenozoic deposits in Italy have been studied to evaluate the ichnology of tidal straits. These comprise four zones: (1) strait centre, (2) dune‐bedded strait zone, (3) strait end and (4) strait margin.

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
