Interseismic Deformation From Sentinel‐1 Burst‐Overlap Interferometry: Application to the Southern Dead Sea Fault

چکیده
Interferometric Synthetic Aperture Radar (InSAR) data are increasingly being used to map interseismic deformation with ascending and descending-orbit observations allowing for resolving the near-east vertical displacement components. The north component has, however, been difficult retrieve due limited sensitivity of standard InSAR in that direction. Here, we address this problem by using time-series analysis along-track interferometric burst-overlap areas Terrain Observation Progressive Scan imaging mode Sentinel-1 radar satellites. We apply method southern part near-north striking Dead Sea transform fault show ∼5 mm/year relative motion is well recovered. Furthermore, results indicate locking depth decreases toward south as it enters transtensional Gulf Aqaba basin. Our can be obtain meaningful rates slow-moving northerly faults.

Modes and rates of horizontal deformation from rotated river basins: Application to the Dead Sea fault system in Lebanon
Partitioning of horizontal deformation between localized and distributed modes in regions of oblique tectonic convergence is, in many cases, hard to quantify. Here we use the geometry of river basins and numerical modeling to evaluate modes and rates of horizontal deformation associated with the Arabia-Sinai relative plate motion in Lebanon. We focus on river basins that drain Mount Lebanon to ...
متن کاملA Quantitative Assessment of DInSAR Measurements of Interseismic Deformation: The Southern San Andreas Fault Case Study
We investigate the capabilities and limitations of the Differential Interferometric Synthetic Aperture Radar (DInSAR) techniques, in particular of the Small BAseline Subset (SBAS) approach, to measure surface deformation in active seismogenetic areas. The DInSAR analysis of low-amplitude, long-wavelength deformation, such as that due to interseismic strain accumulation, is limited by intrinsic ...

S U M M A R Y Studies of interseismic strain accumulation are crucial to our understanding of continental deformation, the earthquake cycle and seismic hazard. By mapping small amounts of ground deformation over large spatial areas, InSAR has the potential to produce continental-scale maps of strain accumulation on active faults. However, most InSAR studies to date have focused on areas where t...
متن کاملPotential and limits of InSAR to characterize interseismic deformation independently of GPS data: Application to the southern San Andreas Fault system
The evaluation of long-wavelength deformation associated with interseismic strain accumulation traditionally relies on spatially sparse GPS measurements, or on high spatial-resolution InSAR velocity fields aligned to a GPS-based model. In this approach the InSAR contributes only shortwavelength deformation and the two data sets are dependent, thereby challenging the evaluation of the InSAR unce...
متن کاملFeasibility study of dam deformation monitoring in northern Sweden using Sentinel1 SAR interferometry
Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. Recently, the technique of Interferometric Synthetic Aperture Radar (InSAR) has proved its potential to measure ground and structural deformation. This geodetic method represents a cost...
