Tectonic evolution of the southern part of Central Viet Nam and the adjacent area

Геодинамика и тектонофизика, 2018
Interpretations of seismic, gravity and magnetic anomalies and structural data on the coastal zone of southern part of Central Viet Nam (SCVN) and the adjacent Tertiary basins suggest several phases in the tectonic evolution of the study region since the

Slab Dehydration Observed Down to Lower Seismicity Plane Depths in the Northern Chile Subduction Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We present a high‐resolution local earthquake tomography model that constrains the distribution of hydration and dehydration processes within the subducting Nazca slab beneath Northern Chile. We image a distinct downdip transition from high Vp/Vs (∼1.75) over low Vp/Vs (∼1.65) to a homogeneously high Vp/Vs slab at depths of ≥ ${\ge} $85 km ...

Mapping the internal structures of fault zones of the sedimentary cover: a tectonophysical approach applied to interpret TDEM data (Kovykta gas condensate field)

Геодинамика и тектонофизика, 2019
The article presents the results of studying the internal structures of platform fault zones with the use of a new tectonophysical approach to processing and interpretation of electrical exploration data obtained by the transient elec‐ tromagnetic method

Hydraulic Control of the Foreshocks and Mainshock of the 2017 Valparaíso, Chile, Earthquake

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Slow‐slip events (SSE) are a key mode of aseismic deformation and can enhance fault permeability through fracturing, enabling fluid migration from the overpressured oceanic crust to the plate interface. Whether the resulting poroelastic stress changes promote seismicity and larger megathrust events, however, remains unclear.

GENETIC SOURCES AND TECTONOPHYSICAL REGULARITIES OF DIVISIBILITY OF THE LITHOSPHERE INTO BLOCKS OF VARIOUS RANKS AT DIFFERENT STAGES OF ITS FORMATION: TECTONOPHYSICAL ANALYSIS

Геодинамика и тектонофизика, 2015
The paper presents the first tectonophysical reconstruction of initial divisibility of the protolithosphere as a result of convection in the cooling primitive mantle. Initial division of the protolithosphere into separate masses, i.e.

Seismic Attenuation Reveals Fault and Forearc Structure Across the Subduction‐Collision Transition in Southern Taiwan

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Southern Array for the Lithosphere and Uplift of Taiwan Experiment (SALUTE) provides a new window into the subduction‐collision transition zone in southern Taiwan, where the Eurasian Plate‐Luzon Arc convergence drives intense orogeny and crustal deformation. Using dense P‐ and S‐wave spectral amplitude data recorded by SALUTE and a quality

Spontaneous rupture on natural fractures and seismic radiation during hydraulic fracturing treatments

Geophysical Research Letters, 2016
We extend spontaneous rupture models in earthquake source studies to analyze fluid injection problems. We perform these analyses on a 2‐D fracture network model with a propagating hydraulic fracture (HF) and three sets of natural fractures (NFs). We find

TECTONOPHYSICAL SIGNS OF THE FORMATION OF STRONG EARTHQUAKE FOCI IN SEISMIC ZONES OF CENTRAL ASIA

Геодинамика и тектонофизика, 2016
Vibrations of the Earth crust and variations in the physical fields of the Earth atmosphere and ionosphere are continuously monitored by a variety of techniques and specialized facilities across the world. Nevertheless, most catastrophic earthquakes even

Seismic source in the Iberian-African plate boundary [PDF]

, 2003
The plate boundary between Iberia and Africa has been studied using data on seismicity and focal mechanisms. The region has been divided into three areas: A; the Gulf of Cadiz; B, the Betics, Alboran Sea and northern Morocco; and C, Algeria.

Constraining the Relative Chronology of Repeated Large Earthquakes in the Longmen Shan Thrust Belt, Eastern Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Yingxiu–Beichuan Fault Zone (YBFZ), located in the Longmen Shan Thrust Belt (LSTB) on the eastern Tibetan Plateau, is highly seismically active. However, direct evidence of large earthquakes at depth is scarce. Here, we present rock magnetic, microstructural, and geochemical analyses of four fault zones from the Wenchuan Earthquake Fault ...
