The relationship between crustal deformation characteristics and strong earthquakes in western China revealed by GNSS

Scientific Reports
To clarify the relationship between GNSS (Global Navigation Satellite System) crustal deformation and the preparation of strong earthquakes in the western Chinese Mainland, a series of methods including velocity field, strain rate field, and strain ...

Relation between Crustal Structures and Crustal Movements in Japan

Journal of Geography (Chigaku Zasshi), 1964
As the present crustal structures have been formed by the tectonic movements through the long geological age, problems of the crustal movements must be studied in connection with the information of the present crustal structures obtained from geological, geomorphological and geophysical methods.

Delineation of deep-seated crustal structures from magnetic data in the southeastern part of the Niger Delta basin, Nigeria

Frontiers in Earth Science
Regional magnetic data in the southeastern segment of the Nigerian Niger Delta were evaluated with the aim of mapping deep-seated tectonic elements. Enhanced filtering operations and 3D forward modelling were applied on the magnetic data.

Crustal structure of the Arteaga Complex, Michoacán, southern Mexico, from gravity and magnetics

Geofísica Internacional, 1997
The Arteaga region, Michoacán, southern Mexico is one of the few areas with basement outcrops in the Guerrero ter¬rane. The Zihuatanejo subterrane is characterized by Late Jurassic-Early Cretaceous island-arc volcanosedimentary se¬quences that rest ...

Crustal velocity structure and composition of Bayan Har block and surrounding areas

Earthquake Research Advances
The Bayan Har block, one of China's most seismically active regions, has experienced multiple major earthquakes (≥M 7.0) in recent years. It is a key area for investigating the interactions between the Qinghai-Xizang (Qingzang) Plateau and adjacent ...

Strong Serpentinization and Hydration in the Subducting Plate of the Southern Mariana Trench: Insights From Vp/Vs Ratios

Geophysical Research Letters
The southern Mariana subduction zone, home to the Challenger Deep—the deepest known point on Earth—poses significant challenges for studying the hydration of the subducting plate due to its extreme depth.

Crustal Structure of Etna Volcano (Italy) From P‐Wave Anisotropic Tomography

Geophysical Research Letters
Several seismic tomographic studies have been carried out to outline the intricate interplay between tectonics and magma uprising at Etna volcano. Most of these studies assume a seismically isotropic crust.

Mercury's Crustal Porosity as Constrained by the Planet's Bombardment History

Geophysical Research Letters
Knowing the structure of the crust is critical to understanding a planet's geologic evolution. Crustal thickness inversions rely on bulk density estimates, which are primarily affected by porosity.
