A Lithospheric Drip Triggered Green and Colorado River Integration
Journal 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 ...

Space Weather, 2020 During magnetic storms, solar‐magnetosphere‐ionosphere‐Earth interactions give rise to geomagnetically induced currents (GICs) in man‐made technological conductors such as power grids, gas pipelines, and railway networks with potentially damaging ...

Crustal deformation, the earthquake cycle, and models of viscoelastic flow in the asthenosphere [PDF]
The crustal deformation patterns associated with the earthquake cycle can depend strongly on the rheological properties of subcrustal material. Substantial deviations from the simple patterns for a uniformly elastic earth are expected when viscoelastic ...

Tectonics, 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.

The Impact of Orogenic Inheritance on Rifted Margin Formation
Tectonics, Volume 45, Issue 2, February 2026.Abstract Many rifted margins form within pre‐existing orogenic belts, emphasizing the significance of structural, thermal, and compositional inheritance in shaping rift dynamics. However, a key unresolved question is how these different types of orogenic inheritance individually influence rift evolution.

The formation of the West European Rift; a new model as exemplified by the Massif Central area [PDF]
, 2001 International audienceIn this paper, we use mainly field data from the Massif Central area, which have been presented in a companion paper (Michon and Merle, 2001), to discuss the origin and the evolution of the West European Rift system.

Geophysical 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.
