Review of the SBAS InSAR Time-series algorithms, applications, and challenges

Geodesy and Geodynamics, 2022
In the past 30 years, the small baseline subset (SBAS) InSAR time-series technique has emerged as an essential tool for measuring slow surface displacement and estimating geophysical parameters. Because of its ability to monitor large-scale deformation with millimeter accuracy, the SBAS method has been widely used in various geodetic fields, such as ...

Deformation Analysis and Reinforcement Effect Evaluation for the No. 65 Slope on the Shangsan Expressway Based on SBAS-InSAR

Buildings
The deformation of the No. 65 slope on the Shangsan Expressway poses a potential threat to road safety. In July 2021, the deformation rate of this slope accelerated significantly, leading to the implementation of reinforcement measures in 2022.

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 ...
