Smart Speed Imaging in Digital Image Correlation: Application to Seismotectonic Scale Modeling
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
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 ...

Modification of the lithospheric stress field by lateral variations in plate-mantle coupling [PDF]
The presence of deeply penetrating continental roots may locally increase the magnitude of basal shear tractions by up to a factor of 4 compared to a layered viscosity structure.

Evidence of Segmentation in the Iberia–Africa Plate Boundary: A Jurassic Heritage?
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
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 ...

Lithospheric failure on Venus [PDF]
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.

In the last decade, the real time ground–based geomagnetic observations realized in correlation with the Vrancea seismicity in Romania, together with supplementary studies related to some earthquakes (Mw9.0 Tohoku, Japan on 11 March 2011 and Mw8.3 ...

Sensitivity kernels or partial derivatives of phase velocity (c) and group velocity (U) with respect to medium parameters are useful to interpret a given set of observed surface wave velocity data.

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.

GEODYNAMICS OF URANIUM ORE FIELDS IN THE WESTERN PART OF THE INHUL MEGABLOK OF THE UKRAINIAN SHIELD
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.
