The Nature of the Lithosphere‐Asthenosphere Boundary
Plate tectonic theory was developed 50 years ago and underpins most of our understanding of Earth's evolution. The theory explains observations of magnetic lineations on the seafloor, linear volcanic island chains, large transform fault systems, and deep

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

Estimation of the effective elastic thickness of the lithosphere: progress and prospects
The lithospheric strength is a key factor in controlling the lithosphere dynamics and deformations. The effective elastic thickness (Te) of the lithosphere can always be used to address the lithospheric strength. Hence, it is a powerful tool for studying

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 ...

Lithospheric failure on Venus [PDF]
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.

Significance We show high-resolution P and S images of the subducted Indian mantle lithosphere, which has been torn into four main pieces. The tearing provides a unified mechanism for (i) Late Miocene and Quaternary rifting, (ii) mantle earthquakes in ...

Seismic anisotropy of Precambrian lithosphere : Insights from Rayleigh wave tomography of the eastern Superior Craton [PDF]
The seismic data used in this study are freely available from the CNDC (Canadian National Data Centre for Earthquake Seismology and Nuclear Explosion Monitoring) and IRIS DMC (Data Management Center) via their data request tools.

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 ...

Several possible lithosphere–atmosphere–ionosphere coupling mechanisms before earthquake occurrence are presented in the literature. They are described by several models with different interaction channels (e.g., electromagnetic, mechanics, chemical ...
