Utilization of Sentinel-1 satellite imagery data to support land subsidence analysis in DKI Jakarta, Indonesia

Journal of Degraded and Mining Lands Management, 2020
Land subsidence had been a significant problem in DKI Jakarta and Semarang, with at least 20 kilometres of roads affected. Repairing them will require at least US $ 1 million per kilometre.

State‐of‐the‐Art Technologies Integrated With InSAR: A Focus on Structural Health Monitoring of Railway Infrastructure

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Interferometric synthetic aperture radar (InSAR) processing is widely implemented to remotely inspect linear infrastructure, such as railway tracks, enabling a wide range of spatiotemporal coverage. Despite InSAR is nowadays integrated with other remote sensing data and in situ measurements to establish structural health monitoring systems of railway ...

Designing an Illegal Mining Detection System based on DinSAR

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
Satellite Differential Radar Interferometry (DInSAR) has demonstrated its ability for monitoring mine-induced ground subsidence. However, it is still a challenging task to routinely identify all mining activities from the large-scale coverage interferogram, especially the illegal mines.

Peatland Surface Motion: Terminology, Measurement Approaches, Models and Insights From a Global Dataset

Ecohydrology, Volume 18, Issue 8, December 2025.
ABSTRACT The surface of peatlands is constantly in motion. While pristine mires are characterized by peat growth and reversible surface fluctuation, induced by water level fluctuations, drained peatlands show subsidence due to peat mineralization and physical compaction. Still, drained peatlands show smaller but marked short‐term surface fluctuation as

Satellite Geodesy Reveals Shallow, Transient Magma Intrusions at Sotará Volcano, Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Sotará is a little‐known andesitic‐dacitic stratovolcano in southwestern Colombia. Although there are no recorded historical eruptions, the volcano shows clear evidence of geothermal activity, deformation, and volcano‐tectonic seismicity. Its remote location and rugged terrain pose challenges for access and routine monitoring.

L2-norm deformation phase unwrapping in mining area driven by matrix pencil model

Meikuang Anquan
To address the limitations of traditional phase unwrapping (PU) approaches in differential interferometric synthetic aperture radar (DInSAR) technology which performs poorly in unwrapping low-coherence deformation interferograms in mining areas, an L2 ...

STABILITY ANALYSIS OF RAILWAY SUBGRADE IN MINING AREA BASED ON DINSAR [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
DInSAR technology have been applied to monitor the mining subsidence and the stability of the railway subgrade. A total of 10 Sentinel-1A images acquired from 2015/9/26 to 2016/2/23 were used in DInSAR analysis. The study mining area is about 13.4

Coseismic Kinematics and Early Afterslip Evolution of the 2025 Mw ${\mathbf{M}}_{\mathbf{w}}$ 7.1 Dingri Earthquake (Southern Tibet) From Space Geodesy

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The 2025 Mw ${\mathrm{M}}_{\mathrm{w}}$ 7.1 Dingri earthquake is a large normal‐faulting event within the Southern Tibet Rift System. We use space‐borne radar interferometry to investigate both coseismic rupture and ∼3‐month early afterslip. Results show that this event ruptured a west‐dipping (48°) fault, exhibiting a predominant normal dip ...

Railway deformation detected by DInSAR over active sinkholes in the Ebro Valley evaporite karst, Spain [PDF]

Natural Hazards and Earth System Sciences, 2015
Subsidence was measured for the first time on railway tracks in the central sector of Ebro Valley (NE Spain) using Differential Synthetic Aperture Radar Interferometry (DInSAR) techniques. This area is affected by evaporite karst and the analysed railway
