Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity‐strengthening friction in barriers and velocity‐weakening friction in asperities. However, afterslip also exhibits spatial overlap with coseismic slip for some events.

Least-Square-Based Joint Coregistration Method for SAR Image Series and Its Application for PS-InSAR Processing

IEEE Access, 2020
Joint coregistration (JC) approach, based on least square (LS) method, is proposed to improve the synthetic aperture radar (SAR) images' coregistration precision and persistent scatterer interferometric synthetic aperture radar (PS-InSAR) performance ...

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 ...

Research on Time Series Monitoring of Surface Deformation in Tongliao Urban Area Based on SBAS-PS-DS-InSAR

Sensors
As urban economies flourish and populations become increasingly concentrated, urban surface deformation has emerged as a critical factor in city planning that cannot be overlooked. Surface deformation in urban areas can lead to deformations in structural

Land Subsidence Susceptibility Mapping in Semi‐Arid Regions Using PS‐InSAR and Tree‐Based Ensemble Machine Learning: A Case Study From Çumra, Türkiye

Transactions in GIS, Volume 30, Issue 4, June 2026.
ABSTRACT Land subsidence is an increasing environmental hazard in semi‐arid agricultural basins where intensive groundwater abstraction, compressible geological units, and expanding land‐use pressures interact. This study presents a PS‐InSAR and machine‐learning‐based framework for land subsidence susceptibility mapping in the Çumra District of the ...

Land subsidence analysis using synthetic aperture radar data

Heliyon, 2023
Land subsidence is considered a threat to developing cities and is triggered by several natural (geological and seismic) and human (mining, groundwater withdrawal, oil and gas extraction, constructions) factors.

Production-Induced Subsidence at the Los Humeros Geothermal Field Inferred from PS-InSAR [PDF]

Geofluids, 2019
Surface deformation due to fluid extraction can be detected by satellite-based geodetic sensors, providing important insights on subsurface geomechanical properties. In this study, we use Differential Interferometric Synthetic Aperture Radar (DInSAR) observations to measure ground deformation due to fluid extraction at the Los Humeros Geothermal Field (

An Upper Bound on Carbon Emissions of Drained Peat Soil Grasslands From Satellite Radar Interferometry

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Drained and cultivated grasslands on peat soils behave as a significant source of greenhouse gasses by oxidation. However, the lack of empirical estimates of carbon losses from peatlands with adequate spatial and temporal resolution has forced researchers to rely on process‐based model approximations to make quantitative, regional‐ or national‐

Geomorphological mapping of the Becca d'Aver deep‐seated gravitational slope deformation (Aosta Valley, Italy) based on multi‐scale and multi‐sensor analysis

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Geomorphological characterization of the DsGSD enables us to identify the sources of sediment that could be mobilized as debris flows. In the area, pseudo‐badlands morphotype has been defined and mapped, representing the main sources of risk beside abandoned quarry deposits.
