Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Both mantle plumes and passive margin extension have been recognized as crucial mechanisms governing intracontinental volcanism and lithospheric evolution. However, the synergistic interactions between these two processes in modulating lithospheric modification remain poorly constrained.

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Precise position and geometry of the subducted slab are crucial for deciphering subduction zone volcanism. This is particularly important in the southern Costa Rican subduction zone, where the Cocos Ridge subducted at ∼2–3 Ma, coincident with the uplift of the Talamanca Range but later than the arc volcanism cessation (∼5–8 Ma). Here, we apply

On the geodynamics of the Aegean rift
Tectonophysics, 2010 The Aegean rift is considered to be either a classic backarc basin, or the result of the westward escape of Anatolia, or the effect of a gravitational collapse of an over-thickened lithosphere. Here these models are questioned. We alternatively present a number of geodynamic and magmatic constraints suggesting a simple model for the genesis of the ...

Analysis of Shear Wave Splitting Patterns in Alaska: Evidence for Strong Intra‐Slab Anisotropy
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Shear wave splitting (SWS) patterns at subduction zones are often interpreted by complex mantle flow above or below the slab. However, our recent previous work shows dipping anisotropic slabs can explain observed patterns in Japan. Here, we extend this analysis to the Alaska subduction zone, using 2,567 high‐quality teleseismic SWS ...

Ice Sheets Without Dynamic Topography
Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract Dynamic topography results in uplift and subsidence events on Earth's surface with amplitudes on the order of a kilometer. These vertical motions are known to have influenced ice sheet evolution, but how dynamic topography has controlled the current state of present ice sheets is unknown.

Magnetic Declination Chart 2006 of Europe – produced by the MagNetE Group
Annals of Geophysics, 2013 During its 4th Workshop in Helsinki in 2009 the Group for European Repeat Station Surveys, MagNetE, decided to produce a European Declination Chart 2006 which is based on the numerous magnetic repeat station measurements performed in more than 20 ...
