Moho Depth of Northern Baja California, Mexico, From Teleseismic Receiver Functions

open access: yesEarth and Space Science, 2021
We estimated Moho depths from data recorded by permanent and temporary broadband seismic stations deployed in northern Baja California, Mexico, using the receiver function technique. This region is composed of two subregions of contrasting geological and

Convergent flow in a two-layer system and mountain building [PDF]

open access: yes, 2010
With the purpose of modelling the process of mountain building, we investigate the evolution of the ridge produced by the convergent motion of a system consisting of two layers of liquids that differ in density and viscosity to simulate the crust and the

Marked lateral variations in the Moho topography below the Uttarakhand Himalaya (India)

open access: yes, 2022
Abstract Utilizing broadband waveform data from 52 stations, we model the detailed crustal structure below the Uttrakhand Himalaya through the Common Conversion Point (CCP) staking of radial P- receiver functions and seismic velocity tomography. We detect marked lateral variations in the Moho depths dipping toward the east (i.e.

Scattering of regional Pn by Moho Topography

open access: yesGeophysical Research Letters, 1991
The often observed relatively large amplitudes in the later part of the Pn signal cannot be explained with the traditional interpretation of Pn in 1‐D crust‐mantle models. To determine the cause of these characteristics we have analyzed in some detail the NORESS array records of Pn from a suite of quarry blasts in S.W. Norway.

S‐velocity model and inferred Moho topography beneath the Antarctic Plate from Rayleigh waves [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2015
AbstractSince 2007/2008, seismographs were deployed in many new locations across much of Antarctica. Using the records from 122 broadband seismic stations, over 10,000 Rayleigh wave fundamental‐mode dispersion curves have been retrieved from earthquake waveforms and from ambient noise.

Geometry and seismic properties of the subducting Cocos plate in central Mexico [PDF]

open access: yes, 2010
The geometry and properties of the interface of the Cocos plate beneath central Mexico are determined from the receiver functions (RFs) utilizing data from the Meso America Subduction Experiment (MASE).

Crustal Thickness Variations and Tectonic Settings in the Southwest Cameroon Inferred from Gravity and Topography Data

open access: yesLithosphere, 2022
EIGEN 6C4 gravity anomalies are interpreted to determine the lateral and vertical variations in the crust and upper mantle structure and their influence on the isostasy of the coastal plain, transition zone between the Congo Craton (CC), the Pan-African ...

The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling [PDF]

open access: yes, 2006
The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...
