Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere
Geochemistry, Geophysics, GeosystemsMost published global and regional shear‐wave (VS) velocity models of cratons include a VS increase with depth below the Moho, with a maximum at 100–150 km depth.

Seismicity at the Rwenzori Mountains, East African Rift: earthquake distribution, magnitudes and source mechanisms [PDF]
, 2012 We have analysed the microseismic activity within the Rwenzori Mountains area in the western branch of the East African Rift. Seismogram recordings from a temporary array of up to 27 stations reveal approximately 800 events per month with local ...

Relation between crustal stress and thickness of earth's crust [PDF]
Podzemni Radovi, 2019 Available models for estimation of crustal stress consider the vertical stress component as weight of above laying rocks, while horizontal stress components are estimated as function of vertical component.

Contributions to Geophysics and Geodesy, 2009 We investigate globally the correlation of the step-wise consolidated crust- stripped gravity field quantities with the topography, bathymetry, and the Moho bound- ary. Global correlations are quantified in terms of Pearson’s correlation coefficient.

Are there superposed Mohos in the south-western Alps? New seismic data from fan-profiling reflections [PDF]
, 2007 International audienceThe Moho preserves imprints of the regional geodynamic evolution of the lithosphere. As such, its detailed topography in divergence or convergence zones has a strong bearing on any geodynamic model. This is still more critical where

Harry Hess and sea-floor spreading [PDF]
, 1999 Harry Hess's hypothesis of sea-floor spreading brought together his long-standing interests in island arcs, oceanic topography, and the oceanic crust. The one unique feature of Hess's hypothesis was the origin of the oceanic crust as a hydration rind on ...

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 ...

Rayleigh wave velocities and structural informations in Central Northern Italy
Annals of Geophysics, 1978 Rayleigh wave dispersion has been observed along the three profiles<br />Trieste-Olbia, Olbia-Bologna and Olbia-Bolzano, in central-northern Italy.<br />The interpretation of phase velocities indicates a crustal thickness increasing<br ...

Joint inversion of Rayleigh wave phase velocity and ellipticity using USArray: Constraining velocity and density structure in the upper crust [PDF]
, 2012 Rayleigh wave ellipticity, or H/V ratio, observed on the surface is particularly sensitive to shallow earth structure. In this study, we jointly invert measurements of Rayleigh wave H/V ratio and phase velocity between 24–100 and 8–100 sec period ...
