The stressed state of the Earth’s crust in the Altai-Sayan mountain region: reconstruction based on the modified algorithms of the cataclastic method [PDF]

open access: yesГеосистемы переходных зон
The article presents the results of a new reconstruction of stress in the Earth’s crust in the Altai-Sayan mountain region and their adjacent territories based on seismological data, and using a new modification of the method of cataclastic analysis ...

Cenozoic evolution of Neotethys and implications for the causes of plate motions [PDF]

open access: yes, 2003
Africa-North America-Eurasia plate circuit rotations, combined with Red Sea rotations and new estimates of crustal shortening in Iran define the Cenozoic history of the Neotethyan ocean between Arabia and Eurasia. The new constraints indicate that Arabia-

Asymmetric continental deformation during South Atlantic rifting along southern Brazil and Namibia [PDF]

open access: yes, 2017
Plate restoration of South America and Africa to their pre-breakup position faces the problem of gaps and overlaps between the continents, an issue commonly solved with implementing intra-plate deformation zones within South America.

Layered Seismic Anisotropy and Tectonics of the Anatolian Plate

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Anatolian tectonics are associated with slab retreat in the west and gravitational potential energy and continental collision in the east, leading to westward motion of Anatolia relative to Eurasia, partially accommodated on the North and East Anatolian transform faults.

Dielectric properties of Granodiorite partially saturated with water and its correlation to the detection of seismic electric signals

open access: yes, 2011
Transient electric signals emitted prior to earthquake occurrence are recorded at certain sites in the Earth's crust termed sensitive. These field observations enforce the laboratory investigation of the dielectric response of rocks forming these ...

Partial Ruptures, Cascading Multi‐Fault Ruptures, and Aftershocks in 2D Random Fault Network

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Gutenberg‐Richter law for the distribution of earthquake magnitude and the Omori law for the decay of aftershocks are two universal laws in seismicity. Although numerical models have been developed to reproduce these laws, they sometimes produce many more foreshocks and fewer aftershocks than observed.

Zones of concentrated deformation (flower structures): field observations and modeling data

open access: yesГеодинамика и тектонофизика, 2018
Our study was focused on narrow linear zones that penetrate to different depths the crust and have complex infrastructure. Rocks in such zones are more intensively tectonically altered in comparison with the background.

Synchrotron FTIR imaging of OH in quartz mylonites [PDF]

open access: yesSolid Earth, 2017
Previous measurements of water in deformed quartzites using conventional Fourier transform infrared spectroscopy (FTIR) instruments have shown that water contents of larger grains vary from one grain to another.

Structural heterogeneity in the megathrust zone and mechanism of the 2011 Tohoku-oki earthquake (Mw 9.0) [PDF]

open access: yes, 2011
The great 2011 Tohoku-oki earthquake (Mw 9.0) and its 339 foreshocks and 5,609 aftershocks (9–27 March 2011) were relocated using a three-dimensional seismic velocity model and local P and S wave arrival times.

The Slip Distributions of the 1952 and 2025 Kamchatka Earthquakes From Tsunami Waveforms Recorded Around the Pacific Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The July 2025 Kamchatka earthquake (Mw 8.8) generated Pacific‐wide tsunamis. Inversion of 40 DART bottom pressure records revealed a large (∼9 m) slip at 200–400 km southwest of the epicenter. This model reproduces the local geodetic data, and is similar to other finite fault models based on teleseismic and geodetic data. Inversion of the tide
