Crustal velocity and Moho structure beneath the Gulf of Corinth, Greece [PDF]

Geophysical Journal International, 2005
The Gulf of Corinth (GOC), Greece is a continental rift with high rates of seismicity and ex-tensional strain. How this strain is accommodated in the crust and whether there are variations in the mechanism along strike remain open questions, in part because of a lack of wide-angle reflection/refraction studies that constrain crustal velocity structure.

Crustal velocity structure in the South Yellow Sea revealed by the joint tomographic inversion of reflected and refracted seismic waves

Frontiers in Earth Science, 2023
The crustal velocity structure in the South Yellow Sea (SYS) Basin is crucial for understanding the basin’s geological structure and evolution. OBS (ocean-bottom station) data from the OBS2013 line have been used to determine the crustal velocity ...

A new approach for inversion of receiver function for crustal structure in the depth domain

Earth and Planetary Physics, 2022
A method for reconstructing crustal velocity structure using the optimization of stacking receiver function amplitude in the depth domain, named common conversion amplitude (CCA) inversion, is presented.

Geological Implications of Crustal Thickness, Vp/Vs, and Poisson's Ratio Beneath the Western Mesopotamian Plain Edge, Iraq

Iraqi Geological Journal, 2023
To know the crustal structure, composition, deformation, and evolution, it is crucial to appreciate the ratio between the velocity of the primary wave and the velocity of the secondary wave, Poisson's ratio, and crustal thickness.

Crustal structures beneath the Eastern and Southern Alps from ambient noise tomography [PDF]

Solid Earth, 2020
We study the crustal structure under the Eastern and Southern Alps using ambient noise tomography. We use cross-correlations of ambient seismic noise between pairs of 71 permanent stations and 19 stations of the Eastern Alpine Seismic Investigation (EASI)

Vestiges of underplating and assembly in the central North China Craton based on S-wave velocities

Scientific Reports, 2021
The destruction of the North China Craton (NCC) is a controversial topic among researchers. In particular, the crustal structure associated with the craton’s destruction remains unclear, even though a large number of seismic studies have been carried out

Crustal S-Wave Velocity Structure Beneath the Northwestern Bohemian Massif, Central Europe, Revealed by the Inversion of Multimodal Ambient Noise Dispersion Curves

Frontiers in Earth Science, 2022
The northwestern Bohemian Massif and adjacent areas are a tectonically active region associated with complex geodynamic activities, that manifest as Quaternary volcanism, earthquake swarms in the upper and middle crust, degassing of CO2, and crustal ...

Ambient Noise Tomography of Upper Crustal Structures and Quaternary Faults in the Seoul Metropolitan Area and Its Geological Implications

Earth and Space Science, 2021
We investigate the upper‐crustal seismic velocity structure in the Seoul metropolitan area, where about 20 million people live. The Chugaryeong fault zone (CFZ) is placed in this area, but the seismic hazard potential remains unclear.
