Geometry, kinematics and rates of deformation in a normal fault segment boundary, central Greece [PDF]

, 2004
The geometry, kinematics and rates of deformation within a fault segment boundary between the ends of two major active normal fault segments have been investigated through examination of a faulted 126 ka marine terrace.

Why blind thrust faults do not propagate to the Earth's surface: Numerical modeling of coseismic deformation associated with thrust‐related anticlines [PDF]

Journal of Geophysical Research: Solid Earth, 1997
High fault‐tip stress concentrations are associated with coseismic slip on blind thrust faults and suggest that these structures should readily propagate to the Earth's surface. Seismic profiles of blind‐thrust‐related earthquakes reveal diffuse zones of aftershocks surrounding the fault tip which are attributed to inelastic deformation, such as ...

Mechanochemical Enhancement of Siderite‐To‐Magnetite Conversion in Faults

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Magnetic phases in fault rocks offer potential “geothermometers” for estimating frictional heating during fault slip. However, the thermochemical kinetics of magnetic minerals subjected to shear deformation in hydrothermal fluids‐conditions typical of natural faults ‐ remains poorly understood, hindering accurate temperature estimates.

Coseismic Shallow Slip Deficit Accounted for by Diffuse Off‐Fault Deformation

Geophysical Research Letters
Earthquake ruptures produce fault slip and kilometer‐wide diffuse deformation of the host rocks. However, the origin of the diffuse deformation and its role in the rupture process are debated.

Coseismic and Early Postseismic Deformation of the 2020 Mw 6.4 Petrinja Earthquake (Croatia) Revealed by InSAR

Remote Sensing, 2023
The largest earthquake (Mw 6.4) in northwestern Croatia ruptured the faults near the city of Petrinja on 29 December 2020, at 11:19 UTC. The epicenter was located ~3 km southwest of Petrinja, ~40 km southeast of Zagreb, the capital of the Republic of ...

Geodetic, teleseismic, and strong motion constraints on slip from recent southern Peru subduction zone earthquakes [PDF]

, 2007
We use seismic and geodetic data both jointly and separately to constrain coseismic slip from the 12 November 1996 M_w 7.7 and 23 June 2001 M_w 8.5 southern Peru subduction zone earthquakes, as well as two large aftershocks following the 2001 earthquake ...

Compound fault rupture during the 2004 off the Kii Peninsula earthquake (M 7.4) inferred from highly resolved coseismic sea-surface deformation [PDF]

Earth, Planets and Space, 2005
For a tsunami inversion analysis, we incorporated a new technique that uses many Green’s functions to improve model spatial resolution. Since this method precisely reproduces observed tsunami waveforms, we can obtain a better model of the tsunami source process.

Size‐Dependent Melting Behavior of Ultrafine Fault Rocks

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Dynamic weakening during earthquake ruptures is essential for accommodating fault slip and controlling seismic energy release. This weakening is localized within narrow principal slip zones (PSZs) that commonly contain nanoparticles in both natural and experimental faults.

Horizontal coseismic deformation of the 1999 Chi-Chi earthquake measured from SPOT satellite images: Implications for the seismic cycle along the western foothills of central Taiwan [PDF]

, 2003
The 1999 Chi-Chi earthquake, M_w = 7.6, broke a major thrust fault along the western foothills of the Central Range of Taiwan. We have measured the horizontal coseismic displacement field by correlating optical satellite images acquired before and after ...

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor
