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

open access: yesAnnals 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.

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

open access: yesGeophysical 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.

Multi‐scale geophysical mapping of the brine and bedrock surfaces along the Dolores River, Paradox Valley, Colorado, December 2023

open access: yesNear Surface Geophysics, Volume 24, Issue 1, Page 36-49, February 2026.
Abstract Total dissolved solids derived from salt dome–sourced brine in the underlying alluvial aquifer substantially increase with distance in the reach of the Dolores River that passes through Paradox Valley in southwestern Colorado. The area has been the site of salinity control operations since the 1990s to reduce salt loading to the downstream ...

Describing the Global Gravity Field of Mars With Lithospheric Flexure and Deep Mantle Flow

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The volcanic complex Tharsis Region on Mars is known for its numerous volcanoes on top of the crust, elevated topography (doming), and a long‐wavelength gravity anomaly correlated with the region. Flexural modeling of the lithosphere has commonly been used to understand the relationship between observed topography, crustal structure, and ...

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

open access: yesEarth 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.

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Late‐Stage Rift Evolution at Back Arc Basins: Insights From a Tomography Experiment at Orca Volcano, Bransfield Basin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Back‐arc basins provide insights into the processes governing the evolution of continental rifting to seafloor spreading. The Bransfield basin hosts a back arc rift that is hypothesized to be in the late stages of this transition. Orca volcano is a submarine volcano that lies on the most evolved portion of the rift.

Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Most published global and regional shear‐wave (VS ${V}_{\mathrm{S}}$) velocity models of cratons include a VS ${V}_{\mathrm{S}}$ increase with depth below the Moho, with a maximum at 100–150 km depth. This feature has long been debated, as it appears to require either (implausible) temperature decreases with depth, or substantial, layered ...

Crustal Structure of Laurentia and Peri‐Gondwanan Terranes Beneath Ireland and Britain and Comparison With Eastern North America

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Appalachian‐Caledonian orogen was built during the Paleozoic by accretion of peri‐Gondwanan terranes onto Laurentia, culminating in the formation of Pangea. During the Mesozoic, Pangea broke apart, displacing one section of the belt to eastern North America and another to northwestern Europe.

Complex local Moho topography in the Western Carpathians: Indication of the ALCAPA and the European Plate contact

open access: yesTectonophysics, 2015
AbstractSeismic data from deep refraction and wide-angle reflection profiles intersecting the Western Carpathians show distinct upper-mantle Pn phases with anomalous apparent velocities identified in the first and later arrivals. Their systematic analysis indicates that such phases are present in numerous seismic sections both for in-line and off-line ...
