Modeling Geoid and Dynamic Topography From Tomography‐Based Thermo‐Chemical Mantle Convection
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract Mantle convection causes the most important contribution to the geoid and dynamic topography. With mantle density inferred from high‐resolution tomography models and numerical methods solving the governing equations of viscous mantle flow, the modeled geoid can fit the observations well.

Moho Depth Disposition of the Contiguous United States: A Multi‐Modal Data Driven Approach
Journal of Geophysical Research: Machine Learning and ComputationPrecise determination of Moho depth is essential for understanding lithospheric deformation, lower crustal rheology, and crust‐mantle interactions. This study employs a Random Forest Regressor (RFR) model to predict Moho depth across the contiguous ...

Moho Fold Structure Beneath the East China Sea and Its Tectonic Implications
Remote SensingMoho fold structures provide critical insights into the tectonic evolution of the East China Sea. However, previous models exhibit substantial uncertainties, primarily resulting from the unaccounted gravitational effects of crustal sources and ...

Contributions to Geophysics and Geodesy, 2014 Using a very fast 1D method of integrated geophysical modelling, we calculated models of the Moho discontinuity and the lithosphere-asthenosphere boundary in the Carpathian-Pannonian Basin region and its surrounding tectonic units. This method is capable

From topography to topography: Surface elevation, Moho geometry and African lithosphere dynamics
, 2014 Multi-seismic experiments acquired across the central and southern part of the Iberian Peninsula provide a new insight into the structure and nature of the lithosphere beneath these areas. Normal incidence and wide-angle seismic reflection data acquired in the area resolve the internal architecture and constrain the distribution of the physical ...

Crustal structure of the Colima rift, western Mexico: gravity models revisited [PDF]
Geofísica Internacional, 1999 Two 250 km and 280 km long gravity transects, across the southern (SCR) and central (CCR) sectors of the Colima rift are reinterpreted. Spectral analysis is used to estimate statistical depths to major interfaces.

A new lithospheric model in the eastern part of the Western Carpatians: 2D integrated modelling
Contributions to Geophysics and Geodesy, 2015 Using 2D integrated geophysical modelling we recalculated lithospheric model along transect KP-X in the eastern part of theWestern Carpathians. Our model takes into account the joint interpretation of the heat flow, free air anomalies, topography and ...

Qinghai-Tibet Plateau crustal thickness derived from EGM2008 and CRSUT2.0
Geodesy and Geodynamics, 2014 Qinghai-Tibet Plateau is the most complex region for crustal thickness inversion, while high-resolution earth gravity model (EGM) makes it possible to obtain high precision gravity anomaly, which is a key parameter to depict the Earth’s inner structure ...

The 2023 Mw 6.8 Morocco Earthquake: A Lower Crust Event Triggered by Mantle Upwelling?
Geophysical Research LettersA M6.8 earthquake struck the High Atlas Mountains in Morocco on 8 September 2023, ending a 63‐year seismic silence. We herein attempt to clarify the seismogenic fault and explore the underlying mechanism for this seismic event based on multiple data sets.
