Complex Shear‐Wave Splitting Behavior in the Northern Andes and Possible Implications for Mantle Flow Around the Caldas Tear

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract We investigate shear‐wave splitting of SKS and SKKS phases from teleseismic earthquakes to study the anisotropic structure of the lithosphere and upper mantle beneath the Colombian Andes. This area is shaped by complex interactions between the subducting Nazca and Caribbean plates beneath the South American plate. A recent broadband deployment

Along‐Strike Seismic Structure of the Andreanof Aleutian Arc Segment and Implications for the Formation of Continental Crust

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Crust formed in volcanic arcs is accreted to continents over geologic time, serving as the source material for new continental crust in Earth's present and recent past. Geochemically, arcs are found to be significantly more mafic than bulk continental crust.

Lunar Crustal Formation by Melt Migration and Differentiation Within a Stagnant Lid

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The lunar anorthosite highlands represent the Moon's primary crust, which formed during the solidification of a magma ocean following the Moon‐forming giant impact. However, the canonical model of anorthite flotation in the crystallizing magma ocean often struggles to reproduce the long > ${ >} $200 Myr solidification timescale required by the

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).
