Evolution of the Upper Crustal Deformation in Subduction Zones [PDF]

open access: yesJournal of Applied Mechanics, 2006
The uplift and evolution of a noncollisional orogen developed along a subduction zone, such as the Andean system, is a direct consequence of the interrelation between plate tectonic stresses and erosion. Tectonic stresses are related to the convergence velocity and thermal state, among other causes.

Measuring and modelling deformation during the Dabbahu (Afar) rifting episode [PDF]

open access: yes, 2010
In September 2005, a 60-km-long dyke intruded the Dabbahu segment of the Nubia-Arabia plate boundary (Afar, Ethiopia), marking the beginning of an ongoing rifting episode.

The influence of surface clinker on the crustal structures and dynamics of 'a'ā lava flows. [PDF]

open access: yes, 2010
Surface structures on 'a'ā and blocky lavas reflect the internal flow dynamics during emplacement and also influence the dynamics of developing flows.

Recent Crustal Deformation in West-Central South America [PDF]

open access: yes, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Crustal flow beneath Iceland [PDF]

open access: yes, 2005
Theoretical and experimental studies indicate that when oceanic crust is hotter than about 800°C, variations in crustal thickness drive lower crustal flow.

Towards using seismic anisotropy to interpret ductile deformation in mafic lower crust [PDF]

open access: yes, 2008
The lower crust forms an important geodynamic control in continental tectonics and the communication and coupling of kinematics between surface and deep-Earth processes.

Complex Crustal Deformation Beneath the Cathaysia Block in South China: Evidence From Receiver Function Analysis

open access: yesEarth and Space Science, 2023
By harmonically fitting the arrival times of the P‐to‐S converted phases from the Moho, we systematically investigate the crustal anisotropy beneath the Cathaysia Block (CaB) and the surrounding areas in South China for the first time.

Stress transmission along mid-crustal faults highlighted by the 2021 Mw 6.5 San Juan (Argentina) earthquake

open access: yesScientific Reports, 2022
Understanding the mechanisms of crustal deformation along convergent margins is critical to identifying seismogenic structures and assessing earthquake hazards for nearby urban centers. In the southern central Andes (28–33 $$^{\circ }$$ ∘ S), differences

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.

Does Large‐Scale Crustal Flow Shape the Eastern Margin of the Tibetan Plateau? Insights From Episodic Magmatism of Gongga‐Zheduo Granitic Massif

open access: yesGeophysical Research Letters, 2022
The mechanisms driving crustal deformation and uplift of orogenic plateaus are fundamental to continental tectonics. Large‐scale crustal flow has been hypothesized to occur in eastern Tibet, but it remains controversial due to a lack of geologic evidence.
