Interseismic Creep Along the Enriquillo–Plantain Garden Fault, Haiti, Estimated From InSAR

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Enriquillo–Plantain Garden fault zone (EPGFZ) is a major left‐lateral strike‐slip fault in southern Haiti hosting several recent destructive earthquakes, including the 2021 MW 7.1 Nippes event with primary thrust‐slip. To investigate how strain is accommodated in the vicinity of the 2021 event, we analyzed Sentinel‐1 interferometric ...

Coseismic gravity and displacement changes of Japan Tohoku earthquake (Mw 9.0)

Geodesy and Geodynamics, 2016
AbstractThe greatest earthquake in the modern history of Japan and probably the fourth greatest in the last 100 years in the world occurred on March 11, 2011 off the Pacific coast of Tohoku. Large tsunami and ground motions caused severe damage in wide areas, particularly many towns along the Pacific coast. So far, gravity change caused by such a great

The Effect of Hydraulic Fracturing on the 2021 Ms 6.0 Luxian Earthquake as Revealed by Deformation and Numerical Simulations

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This study investigates whether hydraulic fracturing contributed to the 2021 Ms 6.0 Luxian earthquake in the Sichuan Basin. Time‐series InSAR analysis of multi‐temporal Sentinel‐1 data reveals coseismic deformation associated with the 2021 Luxian earthquake and localized uplift near hydraulic fracturing platforms.

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

A probabilistic model for coseismic vertical displacement hazard in coastal settings

Geosphere
Characterizing coastal multi-hazards in tectonically active regions requires considering possible coseismic vertical deformation. Coseismic uplift or subsidence can cause near-instantaneous meter-scale relative sea level changes that can exacerbate or reverse the effects of ongoing global sea-level rise.

Temporal changes in surface afterslip along the 2016 Kumamoto earthquake rupture revealed by repeated field surveys

Seismica
Surface afterslip can persist over several years, with displacements reaching tens of centimeters. Such deformations can damage structures, making it crucial to understand their temporal changes for effective post-earthquake reconstruction.

Tectonic Landform and Lithologic Age Impact Uncertainties in Fault Displacement Hazard Models

Geophysical Research Letters
Tectonic landforms and surficial lithologic age are essential data for producing quality late Quaternary fault maps and predicting coseismic fault rupture location before an earthquake.

Influence of fault roughness on surface displacement: from numerical simulations to coseismic slip distributions

Geophysical Journal International, 2019
SUMMARY Field studies have characterized natural faults as rough, non-planar surfaces at all scales. Fault roughness induces local stress perturbations during slip, which dramatically affect rupture behaviour, resulting in slip heterogeneity.

An Adaptive Loose Integration Method for High-Rate GNSS and Strong Motion with Colored Noise

Remote Sensing
Integration of high-rate Global Navigation Satellite Systems (GNSS) with strong motion (SM) sensors enables accurate broadband coseismic displacements, which are critical for earthquake early warning and rapid source inversion.

The Relationship between InSAR Coseismic Deformation and Earthquake-Induced Landslides Associated with the 2017 Mw 3.9 Ischia (Italy) Earthquake

Geosciences, 2018
We investigated the contribution of earthquake-induced surface movements to the ground displacements detected through Interferometric Synthetic Aperture Radar (InSAR) data, after the Mw 3.9 Ischia earthquake on 21 August 2017.
