Automatic GNSS Coordinate Time Series Analysis for Very Large Networks

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract We present a new algorithm, AutoCF, for automatically constructing coordinate functions (CFs) for continuously operating GNSS reference stations (CORSs). The iterative algorithm alternates between application of LASSO and Ridge Regression methods, with hyperparameters successively tightened with each iteration to more judiciously scrutinize ...

Width of surface rupture zone for thrust earthquakes. Implications for earthquake fault zoning.

, 2017
. The characteristics of the zones of coseismic surface faulting along thrust faults are analysed in order to define the criteria for zoning the Surface Fault Rupture Hazard (SFRH) along thrust faults.

Seismic Versus Sub‐Seismic Experimental Mirror‐Like Fault Surfaces in Bituminous Dolostones

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Mirror‐like Surfaces (MSs) are ultra‐polished surfaces frequently found in exhumed seismogenic fault zones in carbonates. They form over a wide range of pressure‐temperature conditions and slip rates, from seismic (≈1 m/s) to sub‐seismic (≈0.1–100 μm/s), reflecting distinct phases of the seismic cycle.

Wenchuan Ms8.0 earthquake coseismic slip distribution inversion

, 2015
By using GPS and gravity data before and after the Wenchuan Ms8.0 earthquake and combining data from geological surveys and geophysical inversion studies, an initial coseismic fault model is constructed.

Fault‐Related Carbonates as Quaternary Seismotectonic and Paleoclimate Archives (Monte Marine Fault, Central Apennines)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Seismogenic faults shape continental landscapes, drive crustal deformation and influence fluid exchange between the lithosphere and atmosphere. Yet, quantitative links between fault activity, exhumation and near‐surface environmental evolution remain poorly understood. Here, structural (meso‐ and micro‐scale) investigations are integrated with

Constraining Shear Strength of Fault Damage Zone Using Geodetic Data and Numerical Simulation

Geophysical Research Letters
Shear strength of damage zone, representing the stress threshold for rupture initiation, is a critical parameter in faulting mechanics. Despite its significance, the damage‐zone's shear strength has not been estimated in natural earthquake ruptures. Here

Earthquakes and the Metamorphic Sole of the Tinos Ophiolite, Cyclades, Greece

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract We analyze deformation fabrics, compositions of melts, metamorphic temperatures, and paleopiezometric data beneath the Tsiknias Thrust, Tinos, Greece, which formed part of the plate boundary that, in Late‐Cretaceous time, absorbed convergence between Africa and Europe associated with final closure of the Vardar Ocean.

Fault Orientation Trumps Fault Maturity in Controlling Coseismic Rupture Characteristics of the 2021 Maduo Earthquake [PDF]

Fault maturity has been proposed to exert a first order control on earthquake rupture, yet direct observations linking individual rupture to long-term fault growth are rare.

Investigating the Milun Fault: The coseismic surface rupture zone of the 2018/02/06 ML 6.2 Hualien earthquake, Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2019
On 6 February 2018, a ML 6.2 earthquake struck the east coast of Taiwan and caused more than 200 casualties in the Hualien area. The mainshock initiated at a shallow depth of 6.3 km and was accompanied by numbers of foreshocks and aftershocks. Coseismic ruptures widely occurred along the Milun Fault with various deformational structures and caused a ...
