Block Kinematics, Interseismic Coupling and Fault Slip Rates in the Aegean Region From GPS and Earthquake Slip Vector Data: 2. Hellenic Subduction System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract The Hellenic subduction system is the primary locus of Nubia‐Eurasia convergence, yet the distribution of strain accumulation along it is still debated. Here, we invert 832 geodetic velocities and 146 earthquake slip vectors to assess the spatial variability of interseismic locking and provide new constraints on the rate of slip deficit ...

Coseismic surface deformation analyses using SAR and optical images: 2023 Kahramanmaraş earthquake sequence, Türkiye

Turkish Journal of Earth Sciences
The 2023 Kahramanmaraş earthquake sequence in Türkiye, including Mw 7.7 and 7.6 mainshocks, caused significant surface ruptures along the East Anatolian Fault (EAF) and Sürgü–Çardak Fault (SCF). We calculated the coseismic displacement fields through pixel offset tracking (POT) analysis of Sentinel-1 SAR data and optical image correlation (OIC ...

Brittle Creep as a Mechanism for Postseismic Relaxation in Upper Crustal Dolomite Marble

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract In many locations, earthquakes in the upper crust occur in carbonate rocks, whose deformation affects aftershock sequences and postseismic relaxation. We investigate the stress relaxation process and strain evolution in Jinping dolomite marble (porosity <0.2%) subjected to multi‐stage stress ramp‐relaxation cycles under confining pressures of ...

Coseismic three-dimensional displacements determined using SAR data: theory and an application test [PDF]

, 2009
We present a methodology to construct three-dimensional deformation maps using different parameters that can be extracted using SAR data. We apply the methodology using ENVISAT SAR data before and after the December 26th, 2003 Mw 6.6 Bam earthquake in ...

Temperature Dependence of Fault Frictional Healing in Quartz Gouges at Hydrothermal Conditions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Fault healing allows the accumulation of stress along faults during interseismic periods. In this critical stage, temperature‐dependent fluid‐rock interactions within fault zones become crucial at seismogenic depth in controlling fault strength recovery. However, frictional healing at hydrothermal conditions is still underexplored.

Coseismic and postseismic displacements related with the 1997 Earthquake Sequence in Umbria-Marche (Central Italy) [PDF]

, 2001
We study the coseismic and postseismic displacements related with the 1997 Umbria-Marche earthquake sequence by means of leveling lines along a deformed aqueduct located in the epicentral area. Comparing the 1960 and 10/1997 measurements we obtain 0.49 0.

Post‐Seismic Variation in Petrophysical Parameters and Heat Storage at the Tuzla Geothermal Field, Biga Peninsula (NW Anatolia) From Resistivity‐Depth Model Using Differential Evolution Algorithm

Geophysical Prospecting, Volume 74, Issue 6, July 2026.
ABSTRACT Electrical resistivity has been shown to offer significant insights into post‐seismic changes in geothermal reservoirs; however, its interpretation is complicated by the fact that it is controlled not only by temperature, but also by porosity and clay content.

Stima della potenza dissipata per attrito durante i terremoti: confronto tra faglie sperimentali e naturali. = Estimate of frictional seismic power dissipation from natural and experimental faults. [PDF]

, 2012
In the last decades, several approaches were applied to understand the physics of seismic faulting. In the field, the recognition of pseudotachylytes (solidified friction melts produced during seismic slip) which record seismic ruptures along a fault ...

Coseismic dislocation modeling by physical experiments [PDF]

, 2013
Detecting coseismic surface deformation provides useful information about geometry and kinematic of the seismo- genic fault activated during an earthquake. Recent advances in inversion of geodetic data (e.g.
