Crustal Flow‐Driven Plateau Growth and Expansion Front in NE Tibet: Insights From High‐Resolution Attenuation Tomography With High‐Density ChinArray Lg Data

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Northeastern (NE) Tibet, as the front of plateau growth, widely absorbs northeastward extrusion, leading to significant uplift and forming a basin‐mountain tectonic framework. However, it remains unclear how the crust of NE Tibet deformed in response to the far‐field effects of the India‐Eurasia collision.

Moho topography beneath the Iberian-Western Mediterranean region mapped from controlled-source and natural seismicity surveys

Tectonophysics, 2016
The complex tectonic interaction processes between the European and African plates at the Western Mediterranean have left marked imprints in the crustal architecture of this area, particularly concerning the lateral variations in crustal thicknesses. The detailed mapping of such variations is hence of large interest, as it provides a major constraint ...

A Seismically Active Shear Zone in the Uppermost Mantle Beneath the Canadian Rockies

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Continental mantle earthquakes are uncommon but hold important clues for understanding lithospheric rheology. Few of these earthquakes (<10) have been documented in western North America, though it is likely more exist owing to difficulties in resolving focal depth for small earthquakes.

Crustal velocity structure of the Apennines (Italy) from P-wave travel time tomography

Annals of Geophysics, 1996
In this paper we provide P-wave velocity images of the crust underneath the Apennines (Italy), focusing on the lower crustal structure and the Moho topography.

Integrated gravity and topography analysis in analog models: Intraplate deformation in Iberia [PDF]

, 2012
Trends in the topography of the Iberian Peninsula show a pronounced contrast. In the western part of the Iberian microplate the main topographic highs trend E-W to NE-SW and are periodically spaced with wavelengths of 250 km.

Influence of station topography and Moho depth on the mislocation vectors for the Kyrgyz Broadband Seismic Network (KNET) [PDF]

Geophysical Journal International, 2013
Deviations of slowness and backazimuth from theoretically calculated values, the so-called mislocation vectors, are measured for the Kyrgyz Broadband Seismic Network (KNET) in the Tien Shan region. 870 events have been analysed for arrivals of P and PKP waves from all azimuths.

Magmatic and Tectonic Structures in the Crust Beneath Armenia and Surrounding Regions of Lesser Caucasus Inferred From Body‐Wave Earthquake Tomography

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract The Armenian Highlands, a tectonically active segment of the Arabia‐Eurasia collision zone, exhibit widespread Quaternary volcanism, rapid uplift, and intense seismicity. However, the lithospheric processes driving these phenomena remain poorly understood.

Evidence of Subduction, Collision, and Extension in Northern Borneo: Constraints From Receiver Functions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract What happens when subduction stops is a key, but poorly understood, part of the tectonic cycle. Northern Borneo (Sabah) with a complex geological history of multiple episodes of subduction, magmatism, uplift, subsidence, and extension since the Mesozoic, is an ideal location for studying post‐subduction processes.

A Novel Iterative Stable Algorithm for Global Moho Modeling in the Spherical Harmonic Domain

Earth and Space Science
The Mohorovičić discontinuity (Moho) marks the boundary between Earth's crust and the underlying mantle, serving as a critical interface for understanding Earth's structure, composition, and geodynamic processes.

Modelling of compression and extension of the continental lithosphere: towards rehabilitation of the necking-level model [PDF]

, 2010
International audienceWe present a dynamic model of continental lithosphere deformation under extension or compression, focusing on the role of an effective mechanical parameter called "necking level" or "necking depth", a widely used concept in basin ...
