Smart Speed Imaging in Digital Image Correlation: Application to Seismotectonic Scale Modeling
Frontiers in Earth Science, 2019 Analog models of earthquakes and seismic cycles are characterized by strong variations in strain rate: from slow interseismic loading to fast coseismic release of elastic energy.

Seismotectonics of Mongolia and Baikal Rift Zone Controlled by Lithospheric Structures
Geophysical Research Letters, 2022 Active tectonics are developing in Mongolia and the Baikal rift zone, where large crustal earthquakes (Mw ≥ 6.0) occur frequently. To clarify the mechanism of these earthquakes, we determine a high‐resolution 3‐D P‐wave velocity model of the crust and ...

Evidence of Segmentation in the Iberia–Africa Plate Boundary: A Jurassic Heritage?
Geosciences, 2019 The present structure of the Iberia−Africa plate boundary between the Gorringe Bank and the Algerian Basin is characterized by a highly segmented geometry and diffused seismicity. Filtered Bouguer gravity data show conspicuous highs coinciding with

THE GLOBAL ENDODRAINAGE SYSTEM: SOME FLUID-PHYSICAL MECHANISMS OF GEODYNAMIC PROCESSES
Геодинамика и тектонофизика, 2019 The article presents the main results of more than forty-year studies of the hydrogeodeformation field. We have establish some new properties of lithospheric massifs, which are clearly detectable during the periods of fast geodynamic activation (FGeDA ...

Geochemistry, Geophysics, Geosystems, 2020 In this work we study the dynamics of double subduction systems with opposite polarity in adjacent segments. A combined approach of numerical and analog experiments allows us to compare results and exploit the strengths of both methodologies.

Lithospheric failure on Venus [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003 Summary: We develop a predictive model which has the ability to explain a postulated style of episodic plate tectonics on Venus, through the periodic occurrence of lithospheric subduction events. Present-day incipient subduction zones are associated with the existence of arcuate trenches on the Venusian lithosphere.

GEODYNAMICS OF URANIUM ORE FIELDS IN THE WESTERN PART OF THE INHUL MEGABLOK OF THE UKRAINIAN SHIELD
Геохімія техногенезу, 2021 The Ingul megablock of the Ukrainian Shield contains a number of endogenous deposits of the sodium-uranium formation, which have been developed for more than 55-60 years.

Discoidal Structure of the Lithosphere [PDF]
Proceedings of the National Academy of Sciences, 1919 Advanced Summary The following discussion seeks to determine inductively the structural character of the lithosphere at depths beyond the reach of observation. The mechanical state of the outer shell of the lithosphere is discussed on the basis of Adams’ experiments with rocks under confining pressures, which demonstrate that pressure increases the ...
