Active crustal deformation model of the Fen–Wei rift zone, North China: Integration of geologic, geodetic, and stress direction datasets

open access: yesFrontiers in Earth Science, 2022
The Fen–Wei rift zone (FWRZ) of North China is an important zone of active crustal deformation representing a transition from extrusion tectonics related to the Tibetan Plateau to subduction tectonics related to the potential far-field influence of the ...

Unrest at Domuyo Volcano, Argentina, detected by geophysical and geodetic data and morphometric analysis [PDF]

open access: yes, 2019
New volcanic unrest has been detected in the Domuyo Volcanic Center (DVC), to the east of the Andes Southern Volcanic Zone in Argentina. To better understand this activity, we investigated new seismic monitoring data, gravimetric and magnetic campaign ...

Advances in Deformable Plate Tectonic Models: 2. Reconstructing the Southern North Atlantic Back Through Time

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The offshore rifted margins of the North Atlantic have a spatially complex crustal structure comprised of variable crustal morphologies, continental blocks, and inherited structures. Recently, deformable plate tectonic models have permitted the interplay

Opposing shear senses in a subdetachment mylonite zone: Implications for core complex mechanics [PDF]

open access: yes, 2010
[1] Global studies of metamorphic core complexes and low‐angle detachment faults have highlighted a fundamental problem: Since detachments excise crustal section, the relationship between the mylonitic rocks in their footwalls and the brittle deformation

Deep lithospheric structures along the southern central Chile Margin from wide-angle P-wave modellilng [PDF]

open access: yes, 2009
Crustal- and upper-mantle structures of the subduction zone in south central Chile, between 42 degrees S and 46 degrees S, are determined from seismic wide-angle reflection and refraction data, using the seismic ray tracing method to calculate minimum ...

Block Motion Changes in Japan Triggered by the 2011 Great Tohoku Earthquake [PDF]

open access: yes, 2017
Plate motions are governed by equilibrium between basal and edge forces. Great earthquakes may induce differential static stress changes across tectonic plates, enabling a new equilibrium state.

Crustal deformation

open access: yesEos, Transactions American Geophysical Union, 1991
One of the lessons of geology, and now one of the tenets of plate tectonics theory, is that most of the Earth's crust does not deform very much. Most of the deformation takes place along the relatively narrow plate boundaries. Working out the details of how this deformation takes place, and the physics of the Earth revealed by it, is a major research ...

The large-scale surface uplift in the Altiplano-Puna region of Bolivia: A parametric study of source characteristics and crustal rheology using finite element analysis [PDF]

open access: yes, 2013
This paper focuses on the driving mechanism behind a 70 km wide region of ground uplift centered on Uturuncu volcano, in the Altiplano-Puna region of southern Bolivia.

Quantifying offshore fore-arc deformation and splay-fault slip using drowned Pleistocene shorelines, Arauco Bay, Chile [PDF]

open access: yes, 2017
Indexación: Web of Science; Scopus.Most of the deformation associated with the seismic cycle in subduction zones occurs offshore and has been therefore difficult to quantify with direct observations at millennial timescales.

Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

open access: yes, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...
