DEFORMATION EXTRACTION AND ANALYSIS OF COSEISMIC DEFORMATION FIELD BASED ON D-INSAR TECHNOLOGY

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Abstract. Extracting the seismic deformation field and analyzing the surface deformation after an earthquake occurs are of great significance for explaining earthquake mechanism and earthquake relief. Through the dual polarization mode of the two-pass method D-InSAR technology, this paper extracted the coseismic deformation fields based on two Sentinel-

Recent Crustal Deformation in West-Central South America [PDF]

open access: yes, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Improved SAR Amplitude Image Offset Measurements for Deriving Three-Dimensional Coseismic Displacements [PDF]

open access: yes, 2015
Offsets of synthetic aperture radar (SAR) images have played an important role in deriving complete three-dimensional (3-D) surface displacement fields in geoscientific applications. However, offset maps often suffer from multiple outliers and patch-like
