Upper Mantle Earthquakes Along the Edge of the Wyoming Craton

open access: yesGeophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Earthquakes in continental regions overwhelmingly occur in the crust where low pressure and temperature promote brittle failure in response to tectonic stress. In rare cases, primarily in the thickened lithosphere near the Himalayas and Tibet, continental earthquakes occur in the uppermost mantle, perhaps implying an abnormally deep brittle ...

Degree of Coupling in 3D Multilayer Continental Lithospheric Buckling: Implications for Tectonic Underpressure

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract The interplay between lithospheric strength contrast and tectonic compression by relative plate motion drives buckling instability. Analysis of lithospheric buckling with plate tectonic history is essential for inferring lithospheric strength.

High‐Resolution Moho Depth and Vp/Vs Mapping Beneath the Carpatho–Pannonian Region Using P‐Wave Coda Autocorrelation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract The Carpathian–Pannonian Region (CPR), including Austria, Slovakia, Hungary, Croatia, Serbia, Romania, and Ukraine, exhibits significant seismic activity, necessitating detailed crustal studies. Despite recent improvements in understanding CPR's crustal structure, it remains poorly known. Here, we applied improved autocorrelation of the P‐wave

Linking Cenozoic Magmatism in the North‐Central Tibetan Plateau With Plateau Growth

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Accurate reconstruction of paleo‐crustal and lithospheric thicknesses is crucial for understanding the deep geodynamic processes driving the uplift and growth of the Tibetan Plateau (TP) and their association with Cenozoic magmatism. We reconstruct the Cenozoic crustal thickness evolution of the north‐central TP using a machine learning model ...

Tesauros: estándares y recomendaciones

open access: yesEl Profesional de la Informacion, 2012
Los tesauros se han adaptado al entorno tecnológico y constituyen una pieza esencial como medio de organización del conocimiento para la web semántica. Tras un largo período sin abordar la actualización de estándares y recomendaciones de los tesauros, en los últimos cinco años se han realizado revisiones en el seno de los organismos normalizadores.

A New Approach to Imaging Deep Crustal Structures: Implications for the Crustal Architecture of Southeast Australia's Passive Margin

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract In the passive margin of southeast Australia, a mosaic of tectonic structures of the Otway Basin records the protracted Cretaceous to Eocene break‐up evolution of Australia and Antarctica. Here, we use an innovative approach that combines Euler deconvolution and DBSCAN clustering of global magnetic data and drill‐hole‐constrained ...
