Machine Learning‐Based New Earthquake Catalog Illuminates On‐Fault and Off‐Fault Seismicity Patterns at the Discovery Transform Fault, East Pacific Rise

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Oceanic transform faults connect spreading centers and are imprinted with previous tectonic events. However, their tectonic interactions are not well understood due to limited observations.

Rifting/spreading propagation interacts with preexisting transform faults: 3D geodynamic modeling

open access: yesFrontiers in Earth Science, 2023
The divergent rifting/spreading centers and the strike-slip transform faults are the essential tectonic units on Earth, the dynamic evolution of which regulates the development of rifting/spreading basins. The propagation of rifting/spreading centers may

Tectonic structure and formation conditions of the submerged plateau and Socotra Island. Part II. Physical modeling

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020
The authors studied the formation conditions and the character of deformations of the margin plateau and Socotra Island using the physical modeling. In experiments, a plate with elastic-plastic properties lying on a liquid base was subjected stretching ...

Rifting continents

open access: yes, 2022
Abstract. Continental rifts can form when and where continents are stretched. If the driving forces can overcome lithospheric strength, a rift valley forms. Rifts are characterised by faults, sedimentary basins, earthquakes and/or volcanism. With the right set of weakening feedbacks, a rift can evolve to break a continent into conjugate rifted margins ...

PIV and topographic analysis data from analogue experiments involving 3D structural inheritance and multiphase rifting [PDF]

open access: yes, 2021
This data set includes videos depicting the surface evolution (time-lapse photographs and Particle Image Velocimetry or PIV analysis) of 38 analogue models, in five model series (A-E), simulating rift tectonics.

Exploring Best Practices in Geoscience Education: Adapting a Video/Animation on Continental Rifting for Upper-Division Students to a Lower-Division Audience

open access: yesGeosciences, 2021
Well-crafted and scientifically accurate videos and animations can be effective ways to teach dynamic Earth processes such as continental rifting, both in live course offerings as well as in online settings.

Measuring and Modeling Viscoelastic Relaxation of the Lithosphere with Application to the Northern Volcanic Zone, Iceland [PDF]

open access: yes, 2010
Viscoelastic relaxation of the stress perturbation caused by an earthquake or diking event can produce measurable ground deformation over 100 km away from the source. We consider the role of viscoelastic relaxation in two different contexts.

Tectonic structure and conditions for the formation of the marginal plateau and Socotra Island (physical modeling). Part 1. Structure of the Socotra Island

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
The structure of the eastern part of the Gulf of Aden is peculiar for the presence of a submerged plateau and the island of Socotra, which were formed at the initial stage of its formation.

A new look at old debates about the Corbières (NE-Pyrenees) geology: salt tectonics and gravity gliding

open access: yesBSGF - Earth Sciences Bulletin, 2023
In the Corbières area, a large-scale nappe has been identified at the beginning of the 20th century: the “Nappe des Corbières Orientales” (NCO) resting over a thick Triassic sole.

Controls on the Thermomechanical Evolution of Hyperextended Lithosphere at Magma-Poor Rifted Margins: The Example of Espirito Santo and the Kwanza Basins [PDF]

open access: yes, 2019
High-quality, long offset seismic data from many distal rifted margins show evidence for hyper-extended,
