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 MONITORING IN DEZHOU CITY BASED ON SBAS-INSAR TECHNOLOGY [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Abstract. To monitor the large area land subsidence in Dezhou city, Shandong province, China. This paper uses 23 scenes of Sentinel-1A radar images from August 2017 to February 2019, and based on small baseline subset (SBAS) technology to obtain the subsidence information in Dezhou urban area. The monitoring results show that: Dezhou city has a serious

Characterisation and multiphase flow modelling of a rock avalanche turned into a supraglacial debris flow: Insights from Mt Job, British Columbia, Canada

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Photographs before (left) and after (right) the May 2023 landslide in Mt Job, Mount Meager Volcanic Complex, British Columbia, Canada. The initial rock avalanche impacted the glacier, producing a 4.5‐km‐long debris flow that ran over it and down the valley.

Nine‐Year L‐Band InSAR Time Series of Tectonic and Non‐Tectonic Surface Deformation in Northern California

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract This study evaluates the performance of ALOS‐2 ScanSAR time series for resolving tectonic, volcanic, hydrologic, and geomorphic deformation across Northern California. Beginning in 2021, ALOS‐2 acquired ScanSAR data with a 14‐day repeat interval over the region, providing the closest available analog to the recently launched NISAR mission. The

Rapid Land Surface Uplift and Groundwater Recovery Observed During the Syrian War

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Recent geopolitical upheaval in Syria is driving regional growth by returning populations, which increases demands on water resources. In northwest Syria, widespread cropland abandonment during the Syrian War starting in 2011 drastically changed the hydrological regime of the region.

Dual impacts of urbanization and precipitation on subsidence in Chongqing revealed by SBAS-InSAR

Environmental Earth Sciences
Abstract Rapid urbanization in Southwest China has exacerbated ground subsidence, imposing severe threats to infrastructure and the environment. However, an understanding of the intricate multi-factorial mechanisms inducing urban subsidence remains inadequate. This study harnesses 44 Sentinel-1A images and InSAR to gauge spaciotemporal patterns

Intelligent Environmental Hazards Detection in Transmission Line Construction Area Based on Remote Sensing and GIS

Engineering Reports, Volume 8, Issue 4, April 2026.
The test results displayed reveal that the proposed method efficiently accomplishes the remote sensing image processing of the area, yielding a differential interferogram of the image. This interferogram accurately represents the area and provides a solid foundation for calculating the environmental hazard zone within the construction area.
