Late Cenozoic Convergence Between the Pamir and the Tianshan Revealed by Low‐Temperature Thermochronology

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The Cenozoic India–Eurasia collision drove widespread deformation across Central Asia, culminating in northward indentation of the Pamir and its eventual contact with the South Tianshan. However, the timing and kinematics of Pamir–Tianshan convergence, as well as its influence on regional topography and climate, remain debated. Here, we report

Exhumation History of the Sangre de Cristo Range, Colorado, From Mid‐ to Low‐Temperature Thermochronology: New Insights Into Laramide Contraction and Oligocene–Miocene Extension in the Northern Rio Grande Rift, USA

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The Sangre de Cristo Range in southern Colorado records a complex tectonic history that includes Late Cretaceous–Eocene Laramide contraction and Oligocene–Quaternary Rio Grande rift extension. We present new thermochronologic data (40Ar/39Ar, fission‐track, (U‐Th)/He) and thermal history models that provide insight into this polyphase history ...

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Seismic Risk of Critical Transport Systems: Sensitivity Analysis of the Campania Railway Network to Bradyseism's Features

open access: yesRisk Analysis, Volume 46, Issue 8, August 2026.
ABSTRACT This study examines the impact of epistemic uncertainties on the seismic risk of a critical transport system, the Campania railway network, during the ongoing bradyseismic unrest at Campi Flegrei, south of Italy. Seismic risk is quantified as the length of the railway requiring post‐event inspection, an operational proxy for service disruption.

Investigating Meter‐Scale Wavefield Complexity and Amplification at the Basin Edge With a Fiber‐Optic Array

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Edges of sedimentary basins generate complex seismic wavefield effects and localized amplification. Characterizing these effects and incorporating them into hazard models is difficult because tomographic models are often smooth and wavefield observations are often aliased.

High‐Resolution Imaging of a Distant M6 Intermediate‐Depth Earthquake Using Ocean‐Bottom DAS and Seismic Network

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Distributed Acoustic Sensing (DAS) provides dense, wide‐aperture observations potentially ideal for imaging earthquake rupture processes. By combining data from a ∼450 km‐long seafloor DAS array offshore Chile and a conventional seismic network, we image an Mw 6.0 intermediate‐depth earthquake ∼400 km away in Argentina, achieving km‐scale ...
