Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.

Uplift of the Transantarctic Mountains: Evidence for an Evolving and Long‐Lived Rayleigh‐Taylor Instability

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Rayleigh‐Taylor instabilities within the upper mantle are investigated as a mechanism for the uplift of rift‐margin mountain ranges within the continents. Our focus is on the Transantarctic Mountains (TAM). These mountains form at the margin between East and West Antarctica and have been free from the effects of subduction for about 500 ...

Inversion by Intrusion: Magma‐Driven Shortening in the Turkana Rift (East Africa)

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Late Pliocene to Pleistocene inversion in the Turkana Rift, observed on seismic reflection data and in outcrop, presents a tectonic paradox by indicating local shortening in an overall extensional setting. Previous studies attributed this inversion either to the reactivation of obliquely oriented structural weaknesses or to reorientation of ...

A Physics‐Based Frequency‐Temperature Seismic Anelastic Attenuation Model for Planetary Ice Shells

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Intrinsic attenuation in planetary ices remains poorly constrained at seismic frequencies and low temperatures, limiting quantitative predictions of wave propagation in icy moons. Existing models typically rely on constant‐Q, or power‐law formulations that lack microphysical grounding and fail to capture the strong temperature sensitivity of ...

Two Distinct Growth Styles of Riedel Shear Zones in Cratonic Strike‐Slip Fault System, Tarim Basin, NW China

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The kinematics and progressive evolution of Riedel shear zones have been extensively studied, yet the factors controlling their distinct evolutionary styles in natural settings remain debated. Understanding such fracture network architecture has great implications, such as predicting subsurface fluid flow and assessing seismic hazards.
